Carbon pricing is a powerful but politically contentious tool for tackling climate change. Governments can, however, try to increase public support for it by adjusting how the revenues raised by the carbon price are used. In a fully incentivized experiment with a large representative sample of the German population, we compare voter support for five different carbon pricing schemes. We show that uniform carbon dividends (equal per capita transfers to all citizens) receive substantially more support than a carbon dividend that favours poorer people, than earmarking revenues for climate projects and especially than using revenues for the general government budget. Among the uniform carbon dividend schemes, a climate premium that pays a fixed upfront transfer equal to the expected carbon revenues receives more support than a carbon dividend scheme where the size of the transfer is determined ex post based on the actual revenues. Furthermore, we show that participants and experts underestimate public support for carbon pricing. These findings suggest that policies for sustainable development gain more support when affected voters are uniformly compensated for the costs imposed on them. In addition, the paper highlights the importance of incentivized experiments in studying public support for such policies. How revenues from a carbon price are returned to society may affect public support for the adoption of such a policy. In an experiment with a large sample of the German population, public support for a carbon price is assessed for five different revenue recycling schemes.
碳定价是应对气候变化的有力工具,但在政治上存在争议。然而,政府可以尝试通过调整碳价带来的收入的使用方式来增加公众对它的支持。在一项充分激励的实验中,我们对德国人口的大量代表性样本进行了比较,比较了选民对五种不同碳定价方案的支持。我们表明,统一的碳红利(向所有公民平等的人均转移)比有利于穷人的碳红利、比专门用于气候项目的收入、特别是比将收入用于一般政府预算的碳红利获得更多的支持。在统一的碳红利计划中,与碳红利计划相比,支付与预期碳收入相等的固定前期转移的气候溢价计划获得了更多的支持,而碳红利计划的转移规模是根据实际收入在事后确定的。此外,我们表明参与者和专家低估了公众对碳定价的支持。这些发现表明,当受影响的选民对施加在他们身上的成本得到统一的补偿时,可持续发展政策获得了更多的支持。此外,本文还强调了激励实验在研究公众对此类政策的支持方面的重要性。碳价收入如何回馈社会,可能会影响公众对采用这一政策的支持。在一项以德国人口为大样本的实验中,对五种不同的收入回收方案评估了公众对碳价的支持。

Environmental policy in the United States is heavily influenced by civil litigation, which is used by government, environmental groups and industry to shape environmental protections. These disputes impact national and global environmental policy, but there is limited knowledge about outcomes for pro- and anti-regulatory plaintiffs or which areas of environmental policy are focused on by different plaintiffs. Drawing on 25,775 environmental civil suits and 4,142 judicial decisions filed in federal district courts between 1988 and 2022, we show that pro-regulatory plaintiffs tend to have a higher win rate than anti-regulatory ones, that federal enforcement litigation focuses overwhelmingly on pollution and waste-related conflicts, that environmental advocacy groups focus heavily on conservation-related conflicts and that climate and environmental justice-related themes are rarely discussed in environmental legal decisions. The inequality in legal advocacy that we document may help to explain areas of strength and weakness in US environmental policy, with implications for environmental justice and global sustainability. Environmental law is shaped by litigation outcomes as much as by legislation. This study examines nearly 30,000 civil suits and court decisions over 34 years to help reveal their influence on the legal and environmental landscapes of the United States.
美国的环境政策在很大程度上受到民事诉讼的影响,政府、环保组织和企业利用民事诉讼来制定环境保护政策。这些纠纷影响着国家和全球环境政策,但人们对支持和反对监管的原告的诉讼结果或不同原告关注的环境政策领域了解有限。根据 1988 年至 2022 年间在联邦地区法院提起的 25775 起环境民事诉讼和 4142 份司法判决,我们发现支持监管的原告往往比反对监管的原告胜诉率高,联邦执法诉讼绝大多数集中在与污染和废物相关的冲突上,环保倡导团体则主要集中在与保护相关的冲突上,而在环境法律判决中很少讨论与气候和环境正义相关的主题。我们所记录的法律宣传中的不平等现象可能有助于解释美国环境政策中的优势和劣势领域,并对环境正义和全球可持续性产生影响。环境法既受诉讼结果的影响,也受立法的影响。本研究考察了 34 年来近 30,000 起民事诉讼和法院判决,有助于揭示它们对美国法律和环境格局的影响。

Environmental law is a function of both regulations and the lawsuits that happen because of, or in the absence of, those regulations. Surveying the characteristics of climate-related lawsuits can help us to understand not just who is suing who, but whether the regulatory and legal system is working as intended.
环境法既有法规的作用,也有因这些法规而发生或在没有这些法规的情况下发生的诉讼的作用。调查与气候有关的诉讼的特点不仅有助于我们了解谁在起诉谁,还有助于我们了解监管和法律体系是否按预期运行。

Communities and individuals are turning to courts to hold governments and high-emitting firms to account for the adverse consequences of climate change. Such litigation is part of a broader trend in which stakeholders are increasingly scrutinizing firms for their sustainability practices. For firms, rising climate litigation risk may exacerbate wider sustainability risks. Here we construct a comprehensive database of filings and decisions relating to 108 climate lawsuits against US- and European-listed firms between 2005 and 2021. We show that firms experience, on average, a 0.41% fall in stock returns following a climate-related filing or an unfavourable court decision. Cases filed against Carbon Majors, primarily the world’s largest fossil fuel producers, saw the largest stock market responses, with returns reducing by 0.57% and 1.50% following filings and unfavourable decisions, respectively. Markets respond more to ‘novel’ climate litigation involving new legal arguments or jurisdictions. Our findings suggest that climate litigation provides a way for stakeholders to challenge actual and perceived weaknesses in the sustainability practices of firms. We conclude that financial markets consider such litigation to be a relevant financial risk. Climate lawsuits can cause direct changes in corporate behaviour, but market impacts are less understood. This study examines 15 years of litigation to find how much stock values fall when lawsuits are filed or resolved.
社区和个人正在诉诸法院,要求政府和高排放企业对气候变化的不利后果负责。利益相关者越来越多地对企业的可持续发展实践进行审查,此类诉讼是这一大趋势的一部分。对企业来说,气候诉讼风险的上升可能会加剧更广泛的可持续发展风险。在此,我们建立了一个全面的数据库,收集了 2005 年至 2021 年间针对美国和欧洲上市公司的 108 起气候诉讼的申请和判决。我们的研究表明,在出现与气候相关的诉讼或不利的法院判决后,企业的股票回报率平均会下降 0.41%。针对碳巨头(主要是世界上最大的化石燃料生产商)提起的诉讼对股市的影响最大,在提起诉讼和法院做出不利判决后,股票回报率分别下降了 0.57% 和 1.50%。市场对涉及新的法律论据或司法管辖区的 "新型 "气候诉讼反应更大。我们的研究结果表明,气候诉讼为利益相关者提供了一种挑战企业可持续发展实践中的实际和感知弱点的途径。我们的结论是,金融市场认为此类诉讼是一种相关的金融风险。气候诉讼可直接改变企业行为,但对市场的影响却不甚了解。本研究对 15 年的诉讼进行了研究,以发现当诉讼被提起或解决时,股票价值会下降多少。

Escalating global plastic pollution and the depletion of fossil-based resources underscore the urgent need for innovative end-of-life plastic management strategies in the context of a circular economy. Thermolysis is capable of upcycling end-of-life plastics to intermediate molecules suitable for downstream conversion to eventually high-value chemicals, but tuning the molar mass distribution of the products is challenging. Here we report a temperature-gradient thermolysis strategy for the conversion of polyethylene and polypropylene into hydrocarbons with tunable molar mass distributions. The whole thermolysis process is catalyst- and hydrogen-free. The thermolysis of polyethylene and polyethylene/polypropylene mixtures with tailored temperature gradients generated oil with an average chain length of ~C14. The oil featured a high concentration of synthetically useful α-olefins. Computational fluid dynamics simulations revealed that regulating the reactor wall temperature was the key to tuning the hydrocarbon distributions. Subsequent oxidation of the obtained α-olefins by sulfuric acid and neutralization by potassium hydroxide afforded sulfate detergents with excellent foaming behaviour and emulsifying capacity and low critical micelle concentration. Overall, this work provides a viable approach to producing value-added chemicals from end-of-life plastics, improving the circularity of the anthropogenic carbon cycle. The controllable conversion of plastic wastes to products with tailored molar mass would facilitate waste valorization but remains challenging. This study presents a catalyst- and hydrogen-free temperature-gradient thermolysis strategy to achieve this goal.
不断升级的全球塑料污染和化石资源的枯竭突出表明,迫切需要在循环经济背景下制定创新的废旧塑料管理战略。热分解能够将废弃塑料升级为适合下游转化为最终高价值化学品的中间分子,但调整产品的摩尔质量分布具有挑战性。在这里,我们报告了一种温度梯度热裂解策略,用于将聚乙烯和聚丙烯转化为具有可调摩尔质量分布的碳氢化合物。整个热解过程是无催化剂和无氢的。在特定温度梯度下,聚乙烯和聚乙烯/聚丙烯混合物热裂解生成的油平均链长为~C14。该油含有高浓度的合成有用α-烯烃。计算流体力学模拟表明,调节反应器壁温度是调节烃类分布的关键。得到的α-烯烃经硫酸氧化后,再经氢氧化钾中和,得到的硫酸盐洗涤剂具有优异的发泡乳化性能和较低的临界胶束浓度。总的来说,这项工作提供了一种可行的方法,从报废塑料中生产增值化学品,改善人为碳循环的循环性。将塑料废物可控地转化为具有定制摩尔质量的产品将促进废物增值,但仍然具有挑战性。本研究提出了一种无催化剂和无氢温度梯度热解策略来实现这一目标。

The spatial imprint of forest disturbances, which can result from a variety of anthropogenic and natural causes, is important in shaping the form and function of the world’s forests. However, we lack a systematic assessment of how the forms of forest disturbances differ globally, which could help in sustainable forest policy and management initiatives to protect forest biomes. Here we produce a global-scale quantification of disturbance patch structures. Using indicators of magnitude, complexity and context, we found that the forms of stand-replacing disturbances can be classified into four broad patterns, whose spatial dominance varies across regions. Human activities were shown to introduce disturbance structures that are not naturally common, especially in the tropics. The consistency of these patterns across biomes outside intact forests suggests that a continuation of current dynamics may lead to a structural homogenization of the world’s forests, with potential consequences for forest ecology and functions. These results provide a greater understanding of the mechanisms governing forest dynamics and elucidating the causal agents of disturbances. This will be a key step towards building more reliable projections of future forest conditions, informing policymaking and ensuring the sustainability of forest management. Forests are subject to natural and human-induced disturbances, which can be important in shaping their form and function. In this study, the authors examine the landscape patterns of global forest disturbance and their drivers to better inform sustainable forest management and policy.
