Urban agriculture in Cuba is often promoted as an example of how agroecological farming can overcome the need for oil-derived inputs in food production. This article examines the geographical implications of Cuba’s low-carbon urban farming based on fieldwork in five organopónicos in Pinar del Río. The article charts how energy flows, biophysical relations, and socially mediated ecological processes are spatially organised to enable large-scale urban agricultural production. To explain this production system, the literature on Cuban agroecology postulates a (...) model of two distinct modes: agroecology versus industrial agriculture. Yet this distinction inadequately explains Cuba’s urban agriculture: production in the organopónicos rather sits across categories, at once involving agroecological, organic-industrial, and petro-industrial features. To resolve this contradiction, a more nuanced framework is developed that conceptualises production systems by means of their geographical configuration. This provides analytical clarity—and a political strategy for a low-carbon, degrowth agenda. (shrink)

Climate change is a wicked problem with causes and consequences overlapping with other wicked problems and no single solution (Hulme 2015). For example, the frequent droughts associated with climate change exacerbate another major problem facing humanity as we enter the Anthropocene: how to produce adequate food to feed a growing population without increasing pollution or “more food with low pollution (MoFoLoPo)” (Davidson et al. 2015). Soils represent an intersection of these two wicked problems, because they are integral to food production (...) through agriculture and also are an important component of global climate models. Recent focus in the field of soil carbon cycling has facilitated a transformation in our understanding of the processes that control this important resource. This understanding is critical to responding to both wicked problems. (shrink)

Permaculture is primarily a thinking tool for designing low carbon, highly productive systems. It originated in Australia in the 1970s and was conceived by Bill Mollison and David Holmgren as a response to the devastating effects of a temperate European agriculture on the fragile soils of an ancient antipodean landscape. Like the dust bowls of the Great Plains in the USA in the 1930s, an alien agriculture has the capacity to turn a delicately balanced ecology into desert. (...) Their initial response was to design a permanent agriculture with tree crops and other perennials inhabiting all the niches from the canopy to the ground cover and below. The soil is left untilled to establish its own robust micro-ecology. Key to this is that the land must be biodiverse and stable for future generations. From perennial tree crops, permaculture has developed into an integrated system of design that encompasses everything from agriculture, horticulture, architecture, and ecology, as well as economy and legal systems for businesses and communities.

Many countries have included agriculture as one of the sectors where they intend to obtain significant greenhouse gas emission reductions. In Norway, the dairy-beef sector, in particular, has been targeted for considerable emission cuts. Despite publicly expressed interest within the agricultural sector for reducing emissions, significant measures have yet to be implemented. In this paper, we draw on qualitative data from Norway when examining the extent the wider agri-food network around farmers promotes or restrains the transition toward low-emission agricultural (...) production. A qualitative analysis based on interviews with key stakeholders from various parts of the agri-food network of dairy-beef indicates that, if it is up to the dairy-beef system itself, it will develop in the direction of continued increased production volumes and increased efficiency in production, combined with moderate measures to reduce emissions. There is an obvious reluctance to stimulate the consumer demand toward other products or meat products with reduced emissions because such a solution would complicate full exploitation of existing agricultural resources and hence could bring considerable negative economic consequences. Another factor limiting the scope and drive towards a low-carbon production is that the effects of various potential climate measures do not appear as unambiguous. Our study indicates that the dairy-beef sector will likely not reach the goal of reduced emissions from its own initiatives. Rather, significant changes would probably require both push and pull support from forces outside the agricultural system. (shrink)

Low-carbon innovation is usually depicted as an exemplar of pursuit of the common good, in both mainstream policy discussion and the emerging orthodoxy of transition studies. Yet it may emerge as a key means of intensifying inequality. We analyse low-carbon innovation as a social and political process through the prism of differential risk-classes, focusing on the pivotal global case of emergence of the Chinese middle-class in seaboard megacities, especially regarding the profound challenges of urban e-mobility transition. This approach (...) shows emergence of this still-forming sociopolitical grouping as tightly and complementarily coupled with the assembling of innovations that meaningfully tackle global risks, such as climate change, while also intensifying existing inequalities. Misrecognition of the duality of low-carbon innovations as both moral technologies and as relatively expensive consumer products has the potentiality to be a key mechanism of this process, thereby serving to reproduce, constitute and legitimize inequalities in novel and unexpected ways.

While most studies of low-carbon transitions focus on green niche-innovations, this paper shifts attention to the resistance by incumbent regime actors to fundamental change. Drawing on insights from political economy, the paper introduces politics and power into the multi-level perspective. Instrumental, discursive, material and institutional forms of power and resistance are distinguished and illustrated with examples from the UK electricity system. The paper concludes that the resistance and resilience of coal, gas and nuclear production regimes currently negates the benefits (...) from increasing renewables deployment. It further suggests that policymakers and many transition-scholars have too high hopes that ‘green’ innovation will be sufficient to bring about low-carbon transitions. Future agendas in research and policy should therefore pay much more attention to the destabilization and decline of existing fossil fuel regimes. (shrink)

As the EU implements measures to tackle the climate emergency on a continental scale, national governmental and economic actors haste to claim better positions in an eco-friendly low carbon market of goods and resources. With this gradual change, surprising factors hinder local community support for the de-carbonized promised future. In order to understand what inspires rural communities to contest and negate green economic action, I investigate a case of local unrest against the erection of an RES plant on public (...) non-arable agricultural land. Drawing upon in-depth interviews with local villagers, rebelling against the photovoltaic plant and municipal representatives, deciding the fate of the land, I outline three main axes of exclusion. These, I argue, fuel the opposition to the EU’s green acts: the symbolic exclusion of differing types of greenness (natural vs political); the geopolitical political exclusion of the local human for the benefit of the global one; the local exclusion, depriving some citizens of legitimate instruments for social claims-making.

Enterprises are the market players for carbon reductions and carbon trading, and they are also the significant driving force in a low-carbon economy and society. Using the data of A-share listed companies from 2010 to 2016, this study uses a difference-in-differences model to examine the effects of the low-carbon city construction on corporate carbon reduction performance. Consistent with our hypotheses, we find that the low-carbon city construction promotes corporate carbon reduction performance. Further analysis (...) indicates that the policy effect is stronger for state-owned enterprises than non-state-owned enterprises. Moreover, environmental quality can affect the promotion of local government officials, which is more prominent in pilot low-carbon cities, and political promotion incentives significantly improve corporate carbon reduction performance. Furthermore, the highest emission reduction effects come in the fourth year after adopting a carbon reduction policy and are concentrated among the firms in the eastern region. Overall, our findings offer a new point view for a deeper understanding of the improvement of corporate carbon reduction performance, and provide microscopic evidence for the objective evaluation of the environmental effects of China's low-carbon city pilot policies.

With the development of industrialization and urbanization, cities have become the main carriers of economic activities. However, the long-term development of cities has also caused damage to resources and the environment. Hence, objective and scientific evaluation of urban low-carbon sustainable development capacity is very important. An index system of urban low-carbon sustainable development capability is constructed in this paper, and a TOPSIS-BP neural network model is established to evaluate the low-carbon sustainable development capability of Beijing, Shanghai, Shenzhen, (...) and Guangzhou in China. At the same time, the difference degree of low-carbon sustainable development level in these four cities is analyzed by standard deviation and coefficient of variation, and the influencing factors of urban low-carbon sustainable development ability are extracted by grey correlation analysis. The results show that the capability of low-carbon sustainable development in four cities is rising and the difference of low-carbon sustainable development capability is decreasing; the general view that the higher the general investment in low-carbon sustainable development, the higher the level of low-carbon sustainable development in cities has not been verified; with the change of time series, the factors affecting the capability of low-carbon sustainable development in the same city are different and the influence of the same factor on the capability of low-carbon sustainable development in different cities is different.

The transition to a low carbon economy demands new strategies to enable organizations to take advantage of the potential for “green” growth. An organization's environmental stakeholders can provide opportunities for growth and support the success of its low carbon strategies, as well as potentially acting as a constraint on new initiatives. Building environmental capabilities through engagement with environmental stakeholders is conceptualized as an important aspect for the success of organizational low carbon strategies. We examine capability building across (...) a range of sectors affected by the sustainability agenda, including construction, rail, water, and health care. We identify a number of emergent environmental stakeholders and explore their engagement with the development of environmental capabilities in the context of the transition toward a low carbon economy. Our conceptual framework offers a categorization of environmental stakeholders based on their position in relation to a focal organization and the potential for the development of environmental capabilities.

‘Methodological cosmopolitanism’ connotes a profound transformation of the (social) sciences as forms of public reflexive social analysis on learning to live well together through building homes in the world: what may be called the ‘Beckian vision’, in memory of Ulrich Beck. This short note considers how Beck’s concept of emancipatory catastrophism may not be the most productive development of his own programme. This is precisely brought out by a methodologically cosmopolitan analysis of a key East Asian response to the global (...) risk of climate change: innovation of low-carbon cities in China. Instead, these presumptively archetypically cosmopolitan initiatives offer something of a political education regarding the irreducibly strategic power/knowledge dynamics at work – including in ongoing contestation about the very term ‘cosmopolitan’.

One major assumption in the climate change debate is that because respondents report positive attitudes to the environment and to low carbon lifestyles they will subsequently engage in environmentally friendly/low carbon behaviors when given the right guidance or information. Many governmental agencies have based their climate change strategy on this basic assumption, despite some anxiety about the value-action gap in psychology more generally. Here we test this assumption. We investigated the relationship between explicit and implicit attitudes to (...) class='Hi'>carbon footprint, and both self-reports of environmental behavior and low carbon behavioral choices. We found that self-reported attitudes to carbon footprint were significantly associated only with self-reported environmental and self-reported low-carbon behaviors. They were not significantly associated with the choice of low carbon alternatives in a simulated shopping task. Given that the vast majority of studies on attitudes and behavior in the environmental domain use self-report measures of behavior, this may mean that we are generating research findings that could be making policy makers overly complacent about our readiness for actual behavior change. Implicit attitudes were not significantly associated with either measure in terms of group comparisons, but those with a strong positive implicit attitude towards low carbon did choose more low carbon items, but only under time pressure. The opposite trend was found for explicit attitudes – this increased only when participants were not under time pressure. These results suggest that Kahneman’s hypothesis about contrasting systems of human cognition might be highly relevant to the domain of climate change and behavioral adaptation. (shrink)

Using data of 26 cities in China from 2004 to 2017, the green total factor productivity is investigated by the SMM-GML method. The corresponding empirical analysis is conducted with the DID model. This paper investigates the relation between low-carbon pilot policy and green total factor productivity and discusses the mediating effect of industrial structure and the number of R&D staff. First, we find that LCC has a significant effect on pilot cities’ GTFP. And, it also promotes GTFP via industrial (...) structure. Second, LCC can improve industrial structure optimization and realization, and industrial structure realization affects GTFP significantly, while optimization cannot. Third, LCC cannot attract more RDS, and RDS harms local GDFP because of talent misallocation. At last, the rate of GTFP presented different upward trends in the order of non-eastern cities and eastern cities. The effect of LCC on GTFP is significant in non-eastern cities, but not eastern ones, which clearly demonstrates the imbalanced development of the green economy. Therefore, the governments of eastern and non-eastern regions should adopt different measures based on local conditions in industrial structure transformation and recruitment and strengthen environmental regulations to make the effect of the low-carbon policy lasting and promote GTFP growth balance in all regions.

An existing industrial hydrogen generation and distribution infrastructure is described, and a number of large-scale investment projects are outlined. All of these projects have the potential to generate significant volumes of low-cost, low-carbon hydrogen. The technologies concerned range from gasification of coal with carbon capture and storage to gasification of a range of biomass streams. These biomass streams derive in turn from the supply chains that feed large liquid biofuel production plants—some operational and the others under construction. Having (...) described how such developments are coming together in a particular location to allow accelerated movement toward a hydrogen economy, this article explores the conditions under which similar acceleration could be seen in other locations.

Much discourse on low-carbon transition envisages progressive social change towards environmentally sustainable and more equitable societies. Yet much of this literature pays inadequate attention to the key question of (productive, relational) power. How do energy infrastructures and socio-technical systems interact with, construct, enable and constrain political regimes, and vice versa? Conceiving low-carbon energy transitions through a power lens, the paper explores a case study of huge, but overlooked, significance: the paradox of the ‘phenomenal’ resurgence of coal in an (...) era of low-carbon innovation. Through exposition of the strong connections between coal-based socio-technical systems and a political regime of classical liberalism, illustrated in two eras, we trace an emerging constellation of energy and political regimes connecting ‘clean coal’ with a ‘liberalism 2.0’ centred on a rising China. This affords a critique of the low-carbon society emergent from these developments – a society more reminiscent of coal's previous Dickensian heyday than the progressive visions of much ‘low-carbon transition’ literature.

Low-carbon technological innovation is the main means to develop a low-carbon economy, and network knowledge sharing and collaborative innovation is an effective model for the development of low-carbon technologies. First of all, this article adopts a decision-making experiment and evaluation laboratory method and interpretation structure model, combines the two methods, extracts the advantages of the two, and discards the shortcomings of the two, thus constructing a new optimized and upgraded interpretation structure model. We give methods to explore (...) the main influencing factors of collaborative innovation of low-carbon technologies for online knowledge sharing. Based on the industrial network knowledge sharing and cooperation network environment, the network evolution game model of network knowledge sharing knowledge collaboration is constructed to study the rewards and punishments, the profit distribution rate, the knowledge potential difference, and the parameter pairing of the network knowledge sharing cooperation network structure in the process of network knowledge sharing and collaborative knowledge innovation. The influence of the network knowledge sharing cooperation strategy is obtained through simulation to change the size of the relevant parameters so that the network knowledge sharing cooperation agent chooses the network evolution game of the sharing strategy to realize the optimal evolutionary stable strategy. According to the simulation results, this article proposes suggestions from the following aspects, aiming to improve the overall knowledge synergy effect of the network knowledge sharing and cooperation network.

In this paper, we study the radial neural network algorithm for low-carbon circular economy in forest area, design a coupled development evaluation model, study its algorithmic ideas operation mode and the update formula obtained by standard algorithm, and finally optimize the RBF neural network by particle swarm algorithm.

Through the analysis and evaluation of the interaction between industrial ecosystem and carbon emission, the main influencing factors of carbon emission are identified, and the size and magnitude of the influence of economic growth, industrial structure, energy intensity, and energy structure on carbon emission are determined; the current situation of the industrial ecological structure is evaluated, and the direction of optimization and adjustment of industrial economic structure, energy structure, and ecological structure is clarified. We construct a multidimensional multiconstraint multimodel industrial ecological structure optimization prediction model, set the development scenarios of economy and society, and optimize the prediction of low-carbon industrial ecological structure in forest areas; based on the simulation analysis of the prediction results, we propose the direction of industrial ecological structure adjustment and the path of industrial ecological system construction.

Under the background that the development of low-carbon circular economy is the objective requirement for the in-depth implementation of scientific development and the inevitable choice for promoting the sustainable development of economy and society, it is not only the requirement of corporate social responsibility but also the path to realize corporate social responsibility. Enterprises should become the representative and model of social responsibility practice in the development of low-carbon circular economy, in order to promote the fulfilment and development (...) of corporate social responsibility in the whole society. Therefore, it is of great theoretical and practical significance to study the realization of corporate social responsibility in the context of low-carbon circular economy. This paper introduces the connotation of low-carbon circular economy and corporate social responsibility, analyses the reality and theoretical basis of realizing corporate social responsibility in low-carbon circular economy, analyses the interactive relationship between the development of low-carbon circular economy and the realization of corporate social responsibility, and puts forward the construction of enterprise low-carbon operation mechanism. This paper uses the research of corporate social responsibility based on radial basis function neural network to build a low-carbon circular economy. The evaluation model of environment economy coupling development is verified by an example, which provides useful guidance for the evaluation and development of corporate social responsibility.

Some ethical imperatives pertaining to climate change are mostly uncontroversial. Humanity has caused the problem and must do something to mitigate it and this job must to a large extent be carried by the current generations, as time is short.

With the implementation of national carbon emission reduction policies and the development of online shopping, manufacturers are making low-carbon efforts and selling products through dual channels. This paper constructs a dual-channel supply chain decision-making model composed of low-carbon emission reduction manufacturers and retailers and studies the optimal decision-making problem of the supply chain under subsidies by the government based on emission reduction R&D and per unit product emission reduction. The research results show the following: when the government (...) subsidizes emission reduction R&D, the emission reduction will have an impact on retailers’ optimal prices, manufacturers’ optimal wholesale prices, and optimal direct sales channel sales prices. The profit of the manufacturer increases with the increase in carbon emissions, and the profit of the manufacturer increases to a certain level and then appears to decline. When the government adopts a subsidy method based on the emission reduction per unit product, the manufacturer’s wholesale price and the selling price of direct sales channels, as well as the retailer’s own optimal price, will increase with the increase in emission reductions. Retailers’ profits will increase linearly with the increase in carbon emissions. Manufacturers’ profits will first increase in a straight line and then increase in a curve. (shrink)

Due to excessive greenhouse gas emissions, carbon emission-reducing measures are urgently needed. Important emission-reduction measures mainly include carbon trading and low-carbon cost subsidies. Comprehensive consideration of these two policies is a research hotspot in the field of low-carbon technology investment. Based on this background, this paper considers the impact of consumer low-carbon preferences on market demand and the impact of uncertainty in carbon emission-reduction behaviour. We construct a stochastic differential game model with upstream and (...) downstream enterprises based on cost-sharing coordination under a cost subsidy. From a dynamic perspective, this paper researches the optimal equilibrium strategy and evolution characteristics of the joint emission-reduction mechanism in a supply chain. This paper discusses the sensitivity of the parameters and uses numerical simulation to verify the impact of each parameter on the emission-reduction decision-making activities of stakeholders after introducing the cost subsidy. The results show that a cost subsidy policy can promote carbon emission-reduction investment and supply chain profit. Thus, it is important to strengthen technical cooperation and exchange among enterprises. (shrink)

This paper tries to investigate the future development tendency of five typical industries in China and find out whether there exists a different innovation strategy preference between Chinese firms of low- and high-knowledge density industry in the background of low-carbon sustainable development. First, this paper finds that the innovation driven-based trend of industrial development is further accelerated in China. Firms in industries with high knowledge and technology density, such as specialized-supplier, scale-intensive, and science-based industries, are more likely to choose (...) exploratory innovation strategy than exploitative innovation strategy. Firms in industries with low knowledge and technology density like service- and supplier-dominated industries are more likely to choose the exploitative innovation strategy. Second, results indicate that exploratory innovation can bring higher technological innovation performance than exploitative innovation. And the effect of the ambidextrous strategy is better than the single exploitative strategy in industries with high knowledge and technology density like specialized-supplier, scale-intensive, and science-based industries. Third, this paper suggests that innovation strategy preference plays a mediating role between industry type and technology innovation and a moderating effect of knowledge management capacity between innovation strategy and firms’ technology innovation.

Energy innovation offers us our best chance to solve the three urgent and interrelated problems of climate change, worldwide insecurity over energy supplies, and rapidly growing energy demand. But if we are to achieve a timely transition to reliable, low-cost, low-carbon energy, the U.S. energy innovation system must be radically overhauled. Unlocking Energy Innovation outlines an up-to-the-minute plan for remaking America's energy innovation system by tapping the country's entrepreneurial strengths and regional diversity in both the public and private spheres. (...) The authors map three waves of energy innovation to show how we can speed up the introduction of new technologies and business models and accelerate their deployment on a massive scale. "Business as usual" will not fill the energy innovation gap. Nor will wishful thinking--common enough today, with politicians and others talking up some technologies, talking down others, and claiming that if we price it, or if we mandate it, or if we simply say it often and inspiringly enough, the innovations will flow. Only the kind of systemic, transformative changes to our energy innovation system described in this provocative book will help us avert the most dire scenarios and achieve a sustainable and secure energy future.

Traditional forms of farming, herding, and fishing are remarkably adapted to African conditions but these traditional approaches are being overtaken by modern pressures, particularly population growth. According to a report published by the Office of Technology Assessment (OTA), a nonpartisan analytical support agency of the U. S. Congress, one promising way to help African farmers and herders would be for development assistance organizations to focus more attention on the various forms of low-resource agriculture that predominate in Africa.In keeping with (...) OTA's mission and primary audience, “Enhancing Agriculture in Africa: A Role for U. S. Development Assistance” (1988) is a policy-oriented synthesis of available technical information.

In October 2010, the German conservative ruling coalition and Free Democratic Party ) passed a law permitting the extension of contracts for Germany’s seventeen nuclear power plants. This policy amended a law passed in 2001 by a Social Democratic Party and Green Party majority to phase out nuclear energy by the early 2020s. The explosions in the nuclear reactors at the Fukushima Daiichi nuclear power facility, however, resulted in a decision to speed up the phaseout of nuclear energy. The nuclear (...) meltdowns in Japan sent hundreds of thousands of protesters onto the streets. Angry voters made their disillusionment with the nuclear politics of the conservative government coalition clear in local elections. The federal government responded by setting up an Ethics Commission for a Safe Energy Supply, which recommended an end to nuclear energy and a shift to a renewable energy-based economy. Within months of the Fukushima disaster, the government had permanently shut down eight of the country’s oldest nuclear power plants and issued a schedule for the phased shutdown of the remaining nine plants by 2022. In addition, the government reaffirmed its climate change plans, which call for a reduction in greenhouse gas emissions by around forty percent of 1990 levels by 2020 and eighty percent by 2050. Thus, out of a crisis, the German government is forging an opportunity to become a global leader in the promotion of new renewable energies, energy efficiency, and greenhouse gas emission reductions. In Japan, the nuclear crisis has also weakened support for nuclear energy, but with a strong industrial coalition calling for its continued use, both for energy stability and in response to climate change, a complete nuclear phaseout is less certain, at least in the short term.

On a larger level, they reveal how the climate crisis is testing the limits of our current moral systems and helping to drive greater ethical innovation and adaptation in the process. (shrink)

Many companies offer their customers voluntary carbon ‘offset’ certificates to compensate for greenhouse gas emissions. Voluntary offset certificates are cheap because the demand for them is low, allowing consumers to compensate for their emissions without significant sacrifices. Regarding the distribution of emission reduction responsibilities I argue that excess emissions are permissible if they are offset properly. However, if individuals buy offsets only because they are cheap, they fail to be robustly motivated to choose a permissible course of action.This suspected (...) lack of robust motivation raises both pragmatic questions about the functioning of offsetting schemes and moral questions about the worth of such unstable motives. The analysis provided here also has wider implications for the normative analysis of partial compliance and ‘many hands’ problems, especially for those cases where compliance levels and costs interact.

Biologists who work on the pig (_Sus scrofa_) take advantage of its similarity to humans by constructing the inferential and material means to traffic data, information and knowledge across the species barrier. Their research has been funded due to its perceived value for agriculture and medicine. Improving selective breeding practices, for instance, has been a driver of genomics research. The pig is also an animal model for biomedical research and practice, and is proposed as a source of organs for (...) cross-species transplantation: xenotransplantation. Genomics research has informed transplantation biology, which has itself motivated developments in genomics. Both have generated models of correspondences between the genomes of pigs and humans. Concerning genomics, I detail how researchers traverse species boundaries to develop representations of the pig genome, alongside ensuring that such representations are sufficiently porcine. In transplantation biology, the representations of the genomes of humans and pigs are used to detect and investigate immunologically-pertinent differences between the two species. These key differences can then be removed, to ‘humanise’ donor pigs so that they can become a safe and effective source of organs. In both of these endeavours, there is a tension between practices that ‘humanise’ the pig (or representations thereof) through using resources from human genomics, and the need to ‘dehumanise’ the pig to maintain distinctions for legal, ethical and scientific reasons. This paper assesses the ways in which this tension has been managed, observing the differences between its realisations across comparative pig genomics and transplantation biology, and considering the consequences of this.

Summary: The evolution of complex societies began when agricultural subsistence systems raised human population densities to levels that would support large scale cooperation, and division of labor. All agricultural origins sequences postdate 11,500 years ago probably because late Pleistocene climates we extremely variable, dry, and the atmosphere was low in carbon dioxide. Under such conditions, agriculture was likely impossible. However, the tribal scale societies of the Pleistocene did acquire, by geneculture coevolution, tribal social instincts that simultaneously enable and (...) constrain the evolution of complex societies. Once agriculture became possible, a competitive ratchet drove further improvements in subsistence and in scale of social organization . Those societies that grew and became better organized were advantaged in individual wealth and economic and military power, and tended to conquer, absorb, or be imitated by smaller and less well organized societies. Internal competitors for power espousing useful social innovations could deliver improved returns when their quest was successful. Notwithstanding the ratchet, social complexity increased only slowly in the first half of the Holocene and even afterwards few periods except the past two centuries saw changes that were dramatic on the scale of individual lifetimes. We attempt a taxonomy of the processes that regulate rates of institutional evolution, cause reversals of complexity against the ratchet, and impose historical contingency on institutional evolution.

A question arising from the COVID-19 crisis is whether the merits of cases for climate policies have been affected. This article focuses on carbon pricing, in the form of either carbon taxes or emissions trading. It discusses the extent to which relative costs and benefits of introducing carbon pricing may have changed in the context of COVID-19, during both the crisis and the recovery period to follow. In several ways, the case for introducing a carbon price (...) is stronger during the COVID-19 crisis than under normal conditions. Oil costs are lower than normal, so we would expect less harm to consumers compared to normal conditions. Governments have immediate need for diversified new revenue streams in light of both decreased tax receipts and greater use of social safety nets. Finally, supply and demand shocks have led to already destabilized supply-side activities, and carbon pricing would allow this destabilization to equilibrate around greener production for the long-term. The strengthening of the case for introducing carbon pricing now is highly relevant to discussions about recovery measures, especially in the context of policy announcements from the European Union and United States House of Representatives. Key Policy Insights: • Persistently low oil prices mean that consumers will face lower pain from carbon pricing than under normal conditions. • Many consumers are more price-sensitive during the COVID-19 context, which suggests that a greater relative burden from carbon prices would fall upon producers as opposed to consumers than under normal conditions. • Carbon prices in the COVID-19 context can introduce new revenue streams, assisting with fiscal holes or with other green priorities. • Carbon pricing would contribute to a more sustainable COVID-19 recovery period, since many of the costs of revamping supply chains are already being felt while idled labor capacity can be incorporated into firms with lower carbon-intensity.

A uniform carbon tax with equal per capita dividends is usually advocated as a cost-effective way of reducing greenhouse gas (GHG) emissions without increasing, and in many cases even reducing, economic inequality, in particular because of the positive balance between the carbon taxes paid by the worse off and the carbon dividends they receive back. In this article, I argue that a uniform carbon tax reform is unjust regardless of how the revenue is used, because it (...) does not discourage the rich from indulging in wasteful emissions. This is at odds with a normative account of the distribution of the GHG budget that I define as emissions limitarianism, which is a climate derivative of economic limitarianism. Emissions limitarianism holds that, under low GHG budget conditions, emissions permits should not be used to achieve functionings that over-consume the GHG budget without producing significant welfare gains relative to the achievement of alternative functionings. Accordingly, I argue that a uniform carbon tax should be complemented by a limitarian carbon tax, which restricts the capabilities of the rich to achieve wasteful emission-generating functionings. The article adopts a methodological multi-level perspective on capabilities as a measure of welfare, distinguishing between basic, secondary and tertiary capabilities. (shrink)

This paper offers a preliminary assessment of the reactions of public agricultural researchers to three terms used currently in the debate surrounding reduced input farming systems: organic, alternative, and sustainable agriculture. It is argued that these terms have been appropriated by the land grant system and their critical content removed to make them palatable to more mainstream agricultural researchers. A national sample of agricultural production researchers is explored, and disciplinary differences in attitudes toward the three terms are assessed. We (...) conclude that sustainable and alternative agriculture do appear acceptable to the mainstream of production researchers, consistent with the hypothesis that they have been appropriated by the land grant system. Moreover, reasons why organic agriculture remains unacceptable are suggested. (shrink)

Carbon monoxide (CO), a product of organic oxidation processes, arises in vivo during cellular metabolism, most notably heme degradation. CO binds to the heme iron of most hemoproteins. Tissue hypoxia following hemoglobin saturation represents a principle cause of CO‐induced mortality in higher organisms, though cellular targets cannot be excluded. Despite extreme toxicity at high concentrations, low concentrations of CO can confer cytoprotection during ischemia/reperfusion or inflammation‐induced tissue injury. Likewise, heme oxygenase, an enzyme that produces CO, biliverdin and iron, as (...) well as a secondary increase in ferritin synthesis, from the oxidation of heme, can confer protection in vivo and in vitro. CO has been shown to affect several intracellular signaling pathways, including guanylate cyclase, which generates guanosine 3′:5′ cyclic monophosphate and the mitogen‐activated protein kinases (MAPK). Such pathways mediate, in part, the known vasoregulatory, anti‐inflammatory, anti‐apoptotic and anti‐proliferative effects of this gas. Exogenous CO delivered at low concentrations is showing therapeutic potential as an anti‐inflammatory agent and as such can modulate numerous pathophysiological states. This review will delve into the biological significance and medical applications of this gas molecule. BioEssays 26:270–280, 2004. © 2004 Wiley Periodicals, Inc. (shrink)

Recycling carbon revenues as Equal Per Capita Carbon Dividends (ECDs) is thought to neutralise the two main objections to carbon pricing, namely that it is regressive and that it hinders the poor from meeting basic needs. This article focuses on the waste objection to carbon pricing plus ECDs. If the rationale for ECDs is to protect the consumption of the worst off, why pay carbon dividends to the rich as well? I examine three different normative (...) arguments in favour of ECDs. First, the argument of common ownership of the atmosphere, which can be based on both libertarianism and isolationist egalitarianism. Second, the argument that the rich are net contributors to ECDs through their carbon taxes. Third, a consequentialist argument focusing on the pragmatic advantages of ECDs, especially in terms of social acceptability and low information costs. I conclude that none of these arguments can provide a normative justification for ECDs. (shrink)

In literature, the firm’s selection of dual-product strategy under cap-and-trade regulation and the optimal emission reduction decisions are not well studied, especially through an analytical approach. We develop a theoretic model to investigate the firm’s selection on three product strategies in the presence of cap-and-trade policy, including two single product strategies and a dual-product strategy, and identify two types of consumers: consumers with low-carbon preference and regular consumers. Our analysis shows that, in the absence of cap-and-trade policy, it is (...) optimal to adopt dual-product strategy, but in the presence of this policy, it is optimal to adopt dual-product strategy or low-carbon product strategy. Compared with ordinary product strategy, adopting a low-carbon product strategy or dual-product strategy benefits the firm under cap-and-trade regulation. The additional cost of producing low-carbon product has an impact on the firm’s product strategy selection under cap-and-trade regulation. When it falls below a certain threshold, it is optimal to adopt a dual-product strategy; otherwise, it is optimal to adopt a low-carbon product strategy. Our research can provide reference for firm’s decision-making and government’s policy formulation. (shrink)

As global warming becomes increasingly prominent, countries worldwide advocate for a low-carbon economy to cope with the pressure to reduce greenhouse gas emissions. The Chinese government has proposed a “dual carbon” goal of peaking carbon emissions by 2030 and becoming carbon neutral by 2060. The disclosure of carbon information by Chinese enterprises has attracted widespread attention from society. This study selects the constituents of the Social Responsibility Index of China Shanghai Stock Exchange from 2016 to (...) 2020 as samples to empirically analyze the relationship between the level of carbon information disclosure and corporate value, and the moderating effect of greenwashing behavior. Results indicated that the quality of carbon disclosure is positively correlated with the enterprise value. Greenwashing behavior promotes the positive impact of carbon disclosure quality on enterprise value in the short run, but this promoting effect fades in the long run. We further found that the carbon information disclosure of non-heavy-pollution enterprises has a more obvious positive impact on enterprise value than that of heavily polluting enterprises. Additionally, the positive impact of carbon information disclosure on enterprise value is more visible among enterprises in a good legal environment than those in a poor legal environment. This study enriches the relevant literature on carbon information disclosure and enterprise “greenwashing” behavior and has practical significance for promoting China’s low-carbon development in the context of ecological civilization and improving the enthusiasm for the quality of enterprise carbon information disclosure.

In the first decade of the twenty-first century, biofuels were recognized as an important element in the overall strategy to reduce climate-forcing greenhouse gases, especially carbon dioxide. Yet scientific research to more fully realize the potential of agricultural crops for liquid transportation fuel requires the coordination of many separate projects housed in different disciplines. Studies predicting and documenting adverse social impacts of plant-based ethanol and biodiesel led to the inclusion of social science components within research teams seeking to develop (...) biofuels. A 2008 rise in global food prices became a centerpiece of this research, leading to a search for non-food crops that could serve as energy feedstocks. Although coordinated scientific research teams have made significant strides toward incorporating social dimensions and broader impacts into what was originally a purely biophysical research effort, a simplistic diagnosis of the tension between agricultural production for food use and agricultural production intended for energy production continues to prevail. Some of the hard questions in the global development of the agricultural sector have been obscured as a result. (shrink)
