Climate advocates and finance industry titans suggest firms’ climate policies have economic payoffs. We examine whether stock markets reward firms that have joined the Science-Based Targets Initiative (SBTi), a voluntary climate program that verifies firms’ emission reduction pledges. Our analysis of S&P 500 companies’ quarterly stock prices for 2010–2023 finds little evidence that SBTi verification (of any type) increases stock prices. If stock markets are not incentivizing firms to voluntarily undertake climate actions, policymakers and climate advocates need to focus on providing nonfinancial rewards to encourage firms to invest in emission reductions.
气候倡导者和金融业巨头都认为企业的气候政策会带来经济回报。我们研究了股票市场是否奖励那些加入了 "基于科学的目标倡议"(SBTi)的公司,该倡议是一项自愿性气候计划,旨在核实公司的减排承诺。我们对 2010-2023 年 S&P 500 强公司的季度股票价格进行了分析,发现几乎没有证据表明 SBTi 验证(任何类型)会提高股票价格。如果股票市场不能激励企业自愿采取气候行动,那么政策制定者和气候倡导者就需要专注于提供非财务奖励,以鼓励企业投资减排。

Research shows that conservatives support fossil fuel extraction and distrust regulation. Yet scholarship overlooks where environmentalist and conservative interests may align—a question I explore through studying a rural, white, and conservative Pennsylvania community where many leased their land for shale gas drilling (fracking). Landowners endorsed fracking and discredited state regulators and environmentalists. Eventually, however, many became troubled by how their land sovereignty and community “home rule” were eroded by petroleum companies and state zoning preemption laws. Though few rejected fracking outright, most believed their town should be allowed to manage the industry’s footprint. Although climate advocates increasingly view local sovereignty as enabling NIMBYism that stymies climate action, communities often experience state-led energy siting policies as a procedural injustice. Regarding fracking, community empowerment would abet climate action by enabling municipal checks on industrial expansion. Environmentalists could forge alliances with rural, conservative towns by supporting greater local democratic decision-making over fracking.
研究表明,保守派支持化石燃料开采,不信任监管。然而,学术界忽略了环保主义者和保守派的利益可能一致的地方--我通过研究宾夕法尼亚州一个农村、白人和保守派社区来探讨这个问题,在这个社区,许多人将土地出租用于页岩气钻探(压裂法)。土地所有者支持压裂法,并诋毁州监管机构和环保人士。但最终,他们的土地主权和社区 "自治 "受到了石油公司和州分区豁免法的侵蚀,这让许多人感到不安。尽管很少有人断然拒绝压裂法,但大多数人认为他们的小镇应该被允许管理该行业的足迹。尽管气候倡导者越来越多地认为地方主权助长了阻碍气候行动的 "NIMBY主义",但社区往往认为州政府主导的能源选址政策是一种程序上的不公正。在压裂技术方面,社区赋权将使市政当局能够对工业扩张进行制约,从而促进气候行动。环保主义者可以通过支持地方在压裂问题上更大程度的民主决策,与保守的农村城镇结成联盟。

Fossil fuel subsidies remain a persistent problem notwithstanding multiple international commitments to phase them out. A new approach is needed to ensure commitments account for, and help overcome, domestic barriers to fossil fuel subsidy reform. This new approach should comprise time-bound roadmaps, steps to close existing loopholes, and support for lower-income countries.
尽管国际社会多次承诺逐步取消化石燃料补贴,但这一问题依然存在。需要采取新的方法,确保承诺考虑到并帮助克服化石燃料补贴改革的国内障碍。这种新方法应包括有时限的路线图、堵塞现有漏洞的步骤以及对低收入国家的支持。

America’s current housing regime—meaning the ways housing is allocated, owned, taxed, and regulated—is a major barrier to the kinds of collective action needed to decarbonize the economy and the atmosphere. We outline why this is the case and argue that major reforms to the housing regime are necessary for fostering collective climate action.
美国目前的住房制度,即住房分配、所有权、税收和监管方式,是经济和大气脱碳所需的集体行动的主要障碍。我们概述了出现这种情况的原因,并认为有必要对住房制度进行重大改革,以促进集体气候行动。

Climate justice issues have been propelled onto political agendas by the recent wave of climate activism, which emphasizes the need for more equitable development. Although a substantial body of research identifies injustices related to climate change, policy research has yet to adequately address this topic. This contribution aims to bridge this gap by advocating for a stronger connection between climate justice and policy analysis. It reviews existing literature, highlighting key focal points in the research, and identifies avenues for future study. The review underscores the need for a more thorough examination of the intersection between policy measures and climate justice.
最近的气候激进主义浪潮强调必须实现更加公平的发展,从而将气候公正问题提上了政治议程。尽管大量研究指出了与气候变化相关的不公正现象,但政策研究尚未充分解决这一问题。本文旨在通过倡导加强气候正义与政策分析之间的联系来弥补这一差距。它回顾了现有文献,强调了研究中的关键焦点,并确定了未来研究的途径。回顾强调了对政策措施与气候正义之间的交叉点进行更深入研究的必要性。

Many actors have recently launched significant new initiatives in the domain of climate change and health. Given this important nexus, we undertook a review of funding patterns from 1985 – 2022, using the NIH RePORTER database for the United States and the Dimensions database globally. This includes an assessment of more than 9 million publicly funded projects across both databases with a collective budget of more than $3 trillion. We estimate that between 1985 and 2022 only 0.26% of research funding awarded by the NIH related to climate change, and only 0.70% of funded projects in the Dimensions database related to climate change and human health. Moreover, we thematically map funding patterns according to four thematic areas: changes in climate, the effects of climate change, health impacts, and interventions and strategies. More funding is needed to better anticipate and prepare for the projected health impacts of climate change.
许多行动者最近在气候变化与健康领域发起了重要的新倡议。考虑到这一重要关系,我们利用美国国立卫生研究院(NIH)的 RePORTER 数据库和全球的 Dimensions 数据库,对 1985 年至 2022 年的资助模式进行了审查。这包括对两个数据库中 900 多万个公共资助项目的评估,这些项目的总预算超过 3 万亿美元。我们估计,在1985年至2022年期间,美国国立卫生研究院(NIH)提供的研究经费中只有0.26%与气候变化有关,而在Dimensions数据库中,只有0.70%的资助项目与气候变化和人类健康有关。此外,我们还根据四个主题领域绘制了资助模式图:气候的变化、气候变化的影响、对健康的影响以及干预措施和战略。我们需要更多的资金来更好地预测气候变化对健康的预期影响,并为此做好准备。

Under the next cycle of target setting under the Paris Agreement, countries will be updating and submitting new nationally determined contributions (NDCs) over the coming year. To this end, there is a growing need for the United States to assess potential pathways toward a new, maximally ambitious 2035 NDC. In this study, we use an integrated assessment model with state-level detail to model existing policies from both federal and non-federal actors, including the Inflation Reduction Act, Bipartisan Infrastructure Law, and key state policies, across all sectors and gases. Additionally, we develop a high-ambition scenario, which includes new and enhanced policies from these actors. We find that existing policies can reduce net greenhouse gas (GHG) emissions by 44% (with a range of 37% to 52%) by 2035, relative to 2005 levels. The high-ambition scenario can deliver net GHG reductions up to 65% (with a range of 59% to 71%) by 2035 under accelerated implementation of federal regulations and investments, as well as state policies such as renewable portfolio standards, EV sales targets, and zero-emission appliance standards. This level of reductions would provide a basis for continued progress toward the country’s 2050 net-zero emissions goal.
根据《巴黎协定》的下一个目标设定周期,各国将在未来一年内更新并提交新的由本国确定的贡献(NDCs)。为此,美国越来越有必要评估实现新的、最雄心勃勃的 2035 年 NDC 的潜在途径。在本研究中,我们使用了一个包含州级细节的综合评估模型,对联邦和非联邦行为者的现有政策进行建模,包括《通货膨胀削减法》、《两党基础设施法》以及各州在所有部门和气体方面的主要政策。此外,我们还开发了一个雄心勃勃的方案,其中包括来自这些参与者的新政策和强化政策。我们发现,与 2005 年的水平相比,到 2035 年,现有政策可使温室气体(GHG)净排放量减少 44%(范围在 37% 到 52% 之间)。在加快实施联邦法规和投资,以及可再生能源组合标准、电动汽车销售目标和零排放设备标准等州政府政策的情况下,到 2035 年,雄心勃勃的情景可实现高达 65% 的温室气体净减排量(范围在 59% 到 71% 之间)。这一减排水平将为继续向该国 2050 年净零排放目标迈进奠定基础。

Do climate acts of EU countries enable the most vulnerable to participate in climate policymaking? 欧盟国家的气候法案是否使最弱势群体能够参与气候决策?

One way to give recognition to and account for vulnerability in climate policymaking is enhanced public participation. This study examines national climate acts across the EU Member States from this perspective, paying particular attention to those members of the public who are considered most climate vulnerable. The analysis finds that few of the acts address public participation, and none of the acts examined directly provides for the participation of specified groups of people based on their presumed vulnerability to climate change impacts. There are, however, participation mechanisms that take into account climate vulnerable groups. Yet, many states have not regarded the national climate act as the legal instrument of choice for regulating public participation in climate policymaking. However, this paper argues that the institutionalization of public participation in the national climate acts would have added value.
在气候政策制定中承认和考虑脆弱性的一种方法是加强公众参与。本研究从这一角度研究了欧盟成员国的国家气候法案,特别关注那些被认为最易受气候影响的公众。分析发现,很少有法案涉及公众参与问题,所审查的法案中也没有一项直接规定特定人群的参与,而这些人群的参与是基于他们对气候变化影响的假定脆弱性。不过,有一些参与机制考虑到了气候弱势群体。然而,许多国家并未将国家气候法案视为规范公众参与气候决策的首选法律文书。然而,本文认为,在国家气候法案中将公众参与制度化将带来附加值。

Perspectives on climate change and infectious disease outbreaks: is the evidence there? 关于气候变化和传染病爆发的观点:有证据吗?

The accelerated warming of the planet caused by anthropogenic climate change is very concerning, as its impacts have the potential to be broad and its effects widespread. One climate change impact with significant interest from scientists, politicians, the media and the general public, is the proposed changes to infectious disease dynamics. Climate change has the potential to alter disease transmission through expansion to naive populations or by worsening risk factors. However, limitations exist in our ability to forecast the climate and disease, including how we incorporate changes in human behaviour and how we attribute climate/weather events solely to an infectious disease outcome. Broad statements about the impact of the climate on infectious disease may not be helpful, as these relationships are highly complex and likely lead to an oversimplification. The interdisciplinary field of climate-health research has the attention of those outside of science, and it is the responsibility of those involved to communicate attribution on an evidence basis, for better scientific communication and public spending. The uncertainty around the impacts of climate change is a call for action, to prevent pushing the Earth’s systems into the unknown.
人为气候变化造成的地球加速变暖非常令人担忧,因为它有可能产生广泛的影响。科学家、政治家、媒体和公众都非常关注的气候变化影响之一,就是传染病动态的拟议变化。气候变化有可能通过向幼稚人群的扩展或风险因素的恶化来改变疾病的传播。然而,我们预测气候和疾病的能力存在局限性,包括我们如何纳入人类行为的变化,以及我们如何将气候/天气事件完全归因于传染病的结果。笼统地说明气候对传染病的影响可能无济于事,因为这些关系非常复杂,很可能导致过度简化。气候-健康研究的跨学科领域受到了科学界以外人士的关注,相关人员有责任在证据的基础上交流归因,以便更好地进行科学交流和公共开支。气候变化影响的不确定性要求我们采取行动,防止将地球系统推向未知。

The uncertainty around the impacts of climate change is a call for action, to prevent pushing the Earth’s systems into the unknown.","PeriodicalId":186004,"journal":{"name":"npj Climate Action","volume":" ","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s44168-024-00115-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141736852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper describes how the ecovillage model for sustainability is currently spreading in Denmark through two different avenues. The first avenue is the creation of new eco-communities inspired by the ecovillage movement but created through top-down municipal support or from the side by the involvement of professional community builders. The second avenue is the spread of some aspects of the ecovillage model to mainstream housing neighbourhoods through the green neighbourhood movement, when neighbours meet, discuss what kind of sustainable interests they share, and act together to live more sustainably. Although eco-communities and green neighbourhoods will probably achieve less impressive carbon footprint reductions than ecovillages, they are exploring interesting avenues through which the spread of the ecovillage model, which is slow, costly, and exclusive, can be speed up and can trigger a mass movement that has the potential of bringing widespread changes.
本文介绍了可持续发展生态村模式目前如何通过两种不同的途径在丹麦传播。第一种途径是受生态村运动的启发,通过自上而下的市政支持或专业社区建设者的参与,创建新的生态社区。第二种途径是通过绿色邻里运动,将生态村模式的某些方面推广到主流住宅区,此时,邻居们会聚在一起,讨论他们共同的可持续利益,并共同行动,以更可持续的方式生活。虽然生态社区和绿色街区在减少碳足迹方面的成果可能不如生态村那么显著,但它们正在探索一种有趣的途径,通过这种途径,可以加快生态村模式的推广,因为生态村模式的推广速度慢、成本高,而且具有排他性,可以引发一场群众运动,从而有可能带来广泛的变化。
