This document presents one view in a debate on the relevance of environmental impact assessment as a tool for climate change mitigation. In this piece, I argue that CA is emerging as a rule of customary international law, and that, moreover, it is a potentially useful mitigation tool. In another piece included in the same volume, Alexander Zahar questions the meaningfulness of CA, arguing that it is impossible to determine what constitutes a significant, excessive, or disproportionate emission of greenhouse gases in the case of a proposed activity subject to CA, or at all.
本文件在关于环境影响评估作为减缓气候变化工具的相关性的辩论中提出了一种观点。在这篇文章中,我认为CA正在成为习惯国际法的一项规则,而且,它是一种潜在的有用的缓解工具。在同一卷的另一篇文章中,Alexander Zahar对CA的意义提出了质疑,他认为,在受CA约束的拟议活动中,不可能确定什么构成了显著的、过度的或不成比例的温室气体排放,或者根本不可能确定。

The costs of the wildfire crisis in California have become uninsurable. This Note argues that the California Legislature must equitably invest in collective resiliency and mitigation efforts to minimize statewide losses before they occur, rather than focus on ex post liability schemes. It proposes a statutory amendment that would require private electric utilities to retrofit their lowest-income ratepayers' homes to fire-hardened standards in areas of high wildfire risk.
加州山火危机造成的损失已经无法投保。本说明认为,加州立法机构必须公平地投资于集体复原力和减灾努力,以便在全州范围内的损失发生之前尽量减少损失,而不是侧重于事后责任计划。它提出了一项法律修正案,要求私营电力公司对其最低收入纳税人的房屋进行改造,使其达到火灾高风险地区的防火标准。

Pricing of Climate Risk Insurance: Regulatory Frictions and Cross-Subsidies 气候风险保险定价:监管摩擦与交叉补贴
Pub Date : 2021-02-01 DOI: 10.2139/ssrn.3762235

Homeowners’ insurance provides households financial protection from climate losses. To improve access and affordability, state regulators impose price controls on insurance companies. Using novel data, we construct a new measure of rate setting frictions for individual states and show that different states exercise varying degrees of price control, which positively correlates with how exposed a state is to climate events. In high friction states, insurers are more restricted in their ability to set rates and adjust rates less frequently and by a lower amount after experiencing climate losses. In part, insurers overcome pricing frictions by cross-subsidizing insurance across states. We show that in response to losses in high friction states, insurers increase rates in low friction states. Over time, rates get disjoint from underlying risk, and grow faster in states with low pricing frictions. Our findings have consequences for how climate risk is shared in the economy and for long-term access to insurance.
房主保险为家庭提供气候损失方面的经济保护。为了提高保险的可及性和可负担性,州监管机构对保险公司实施价格控制。使用新的数据,我们构建了一个新的衡量单个州的价格设定摩擦的方法,并表明不同的州行使不同程度的价格控制,这与一个州对气候事件的暴露程度呈正相关。在高摩擦的州,保险公司在经历气候损失后,在设定费率和调整费率的频率和金额方面受到更多限制。在某种程度上,保险公司通过跨州交叉补贴保险来克服定价摩擦。我们表明,为了应对高摩擦状态下的损失,保险公司增加了低摩擦状态下的费率。随着时间的推移,利率与潜在风险脱节,在价格摩擦较低的州,利率增长更快。我们的研究结果对气候风险在经济中的分担方式以及长期获得保险的方式产生了影响。

Climate Change Law and Brazil: Climate Litigation As the Ultimate Ratio? 气候变化法与巴西:气候诉讼作为终极比例?
Pub Date : 2020-07-01 DOI: 10.2139/ssrn.3640847

The challenges posed by global warming require commitment and effective action from all countries. The hopes placed on the Paris Agreement have not yet materialized and, in many situations, due to the State's inaction or omission. As a result, this situation has led to demands by nationals against their own countries demanding a more effective stance in protecting their nationals from the consequences of global warming. This research has as its theme climate litigation as a citizen alternative and ultimate ratio in the fight against such a challenge. As a general objective, this research intends to analyze the foundations that underlie the judicial processes involving the issue of climate change in different countries and, from this analysis, to evaluate the situation of Brazil in this context, that is, this research also aims to analyze the possibilities and grounds of litigation in Brazil considering the theme of climate change. Regarding the methodology employed, the inductive research method was adopted, which starts from the analysis of specific cases in order to reach a conclusion of the theme. The article concludes that global governance of the environment for climate change, while making progress in implementing the Paris Agreement in 2015, has failed to make progress in reducing global greenhouse gas emissions. Due to the inaction and / or omission of some countries in fulfilling their commitments in Paris, climate litigation has emerged as an alternative to reverse this situation. The main grounds for climate change demands are commitments under the Paris Agreement, but they also involve constitutionally guaranteed human rights issues. Based on the examples brought to the discussion and the foundations that supported these demands, it can be concluded that governmental behavior, for example, the growth in deforestation and burning in the Amazon is sufficient for the exercise of climate litigation in Brazil.
全球变暖带来的挑战需要所有国家作出承诺并采取有效行动。对《巴黎协定》寄予的希望尚未实现,在许多情况下,这是由于国家的不作为或不作为。因此,这种情况导致各国人民对本国提出要求,要求采取更有效的立场,保护本国人民免受全球变暖的影响。本研究以气候诉讼作为公民应对这一挑战的选择和终极比例为主题。作为总体目标,本研究旨在分析涉及气候变化问题的司法程序在不同国家的基础,并从这个分析中评估巴西在这一背景下的情况,也就是说,本研究还旨在分析巴西在考虑气候变化主题的情况下进行诉讼的可能性和理由。在方法论上,采用归纳研究法,从具体案例分析入手,得出主题结论。文章的结论是,全球气候变化环境治理虽然在2015年实施《巴黎协定》方面取得了进展,但在减少全球温室气体排放方面却未能取得进展。由于一些国家在履行其在巴黎的承诺方面无所作为和/或遗漏,气候诉讼已成为扭转这种局面的另一种选择。气候变化要求的主要依据是《巴黎协定》下的承诺,但也涉及宪法保障的人权问题。根据讨论中的例子和支持这些要求的基础,可以得出结论,政府行为,例如亚马逊森林砍伐和焚烧的增长,足以在巴西进行气候诉讼。

The Response of Local Corporate Sustainability to Environmental Disasters: Evidence from Wildfires 地方企业可持续性对环境灾害的反应:来自野火的证据
Pub Date : 2020-07-01 DOI: 10.2139/ssrn.3640791

Environmental disasters are thought to increase the focus on corporate sustainability in the communities where they occur. Extracting data on wildfires (a frequent type of disaster in the U.S.), and using two rating agencies and EPA air enforcement actions to construct measures of local corporate sustainability, we study this conjecture. We show that severe wildfires in a county increase significantly its corporate environmental sustainability in the following year. This effect is not driven by pre-trends, such as the implementation of existing sustainability programs, nor does it exhibit post-trends, such as reversion or further growth of sustainability in later years. The impact is not homogeneous across counties: it is significant only in counties where the percentage of anthropogenic climate change believers is high, or where the majority of voters are Democrats.
人们认为,环境灾难使发生环境灾害的社区更加关注企业的可持续性。提取野火(美国常见的灾害类型)的数据,并使用两个评级机构和美国环保署的空气执法行动来构建当地企业可持续性的措施,我们研究了这一猜想。我们发现,一个县的严重野火在接下来的一年里显著增加了其企业的环境可持续性。这种效应不是由前趋势驱动的,比如现有可持续性项目的实施,也不是由后趋势驱动的,比如可持续性在以后几年的恢复或进一步增长。这种影响在各个县之间并不相同:只有在相信人为气候变化的比例很高的县,或者大多数选民是民主党人的县,这种影响才会显著。

The Iberian Peninsula is close to the Eurasia-Africa plate boundary resulting in a considerable seismic hazard. In fact, the southwestern Iberian Peninsula is affected by far away earthquakes of long-return period with large-very large magnitude. A project named PERSISTAH (Projetos de Escolas Resilientes aos SISmos no Território do Algarve e de Huelva, in Portuguese) aims to cooperatively assess the seismic vulnerability of primary schools located in the Algarve (Portugal) and Huelva (Spain). Primary schools have been selected due to the considerable amount of similar buildings and their seismic vulnerability. In Portugal, the Decreto Lei 235/83 (RSAEEP) is mandatory while in Spain, the mandatory code is the Seismic Building Code (NCSE-02). In both countries, the Eurocode-8 (EC-8) is recommended. Despite the fact that both regions would be equally affected by an earthquake, both seismic codes are significantly different. This research compares the seismic action of Ayamonte (Huelva) and Vila Real de Santo António (Portugal). Both towns are very close and located at both sides of the border. Moreover, they share the same geology. This analysis has been applied considering a reinforced concrete (RC) primary school building located in Huelva. To do so, the performance-based method has been used. The seismic action and the damage levels are compared and analysed. The results have shown considerable differences in the seismic actions designation, in the performance point values and in the damage levels. The values considered in the Portuguese code are significantly more unfavourable. An agreement between codes should be made for border regions.
伊比利亚半岛靠近欧亚板块边界,造成了相当大的地震危险。事实上,伊比利亚半岛西南部受到遥远地震的影响,这些地震具有长周期的大-特大震级。一个名为PERSISTAH(葡萄牙语:project jetos de Escolas Resilientes aos SISmos no Território do Algarve e de Huelva)的项目旨在合作评估位于阿尔加维(葡萄牙)和韦尔瓦(西班牙)的小学的地震脆弱性。选择小学是因为有相当数量的类似建筑和它们的地震脆弱性。在葡萄牙,法令235/83 (RSAEEP)是强制性的,而在西班牙,强制性规范是抗震建筑规范(NCSE-02)。在这两个国家,推荐使用欧洲代码8 (EC-8)。尽管这两个地区同样会受到地震的影响,但这两个地区的地震规范却有很大的不同。本研究比较了Ayamonte (Huelva)和Vila Real de Santo António(葡萄牙)的地震作用。这两个城镇都很近,位于边界的两侧。此外,它们拥有相同的地质。该分析已应用于位于Huelva的钢筋混凝土(RC)小学建筑。为此,采用了基于性能的方法。对地震作用和损伤程度进行了比较分析。结果表明,在地震作用的指定,在性能点值和损伤水平上存在相当大的差异。葡萄牙法典中所考虑的价值观明显更为不利。边境地区应达成代码间协议。

Residential Water Quality and the Spread of COVID-19 in the United States 美国住宅水质与COVID-19的传播
Pub Date : 2020-04-09 DOI: 10.2139/ssrn.3572341

Sanitation and hygiene practices to limit the spread of COVID-19 require ample water supply, and communities with poor or untrusted residential water infrastructure rely on bottled water retrieved from outside the home. Thus ability to adhere to sanitation and shelter-in-place recommendations may be limited for households lacking a safe, reliable, and trustworthy piped water source. Consistent with this hypothesis, the number of confirmed COVID-19 cases has grown faster in counties with lower-quality residential water infrastructure. These findings suggest that, in the short run, distribution of potable water to water-poor households may help slow the spread of COVID-19 or ameliorate community health consequences, and in the long run, investment in residential water infrastructure may increase resilience to future pandemics.
限制COVID-19传播的环境卫生和个人卫生做法需要充足的供水,而住宅供水基础设施差或不可信的社区依赖于从家庭外获取的瓶装水。因此,对于缺乏安全、可靠和值得信赖的管道水源的家庭,遵守卫生和就地安置建议的能力可能有限。与这一假设相符的是,在居民用水基础设施质量较差的县,新冠肺炎确诊病例的增长速度更快。这些研究结果表明,从短期来看,向缺水家庭分配饮用水可能有助于减缓COVID-19的传播或改善社区健康后果,从长期来看,对住宅供水基础设施的投资可能会提高对未来流行病的抵御能力。

The Propagation of the Economic Impact through Supply Chains: The Case of a Mega-City Lockdown against the Spread of COVID-19 经济影响通过供应链传播:以大城市封锁疫情为例
Pub Date : 2020-03-31 DOI: 10.2139/ssrn.3564898

This study quantifies the economic effect of a possible lockdown of Tokyo to prevent spread of COVID-19. The negative effect of the lockdown may propagate to other regions through supply chains because of shortage of supply and demand. Applying an agent-based model to the actual supply chains of nearly 1.6 million firms in Japan, we simulate what would happen to production activities outside Tokyo when production activities that are not essential to citizens' survival in Tokyo were shut down for a certain period. We find that when Tokyo is locked down for a month, the indirect effect on other regions would be twice as large as the direct effect on Tokyo, leading to a total production loss of 27 trillion yen in Japan, or 5.3% of its annual GDP. Although the production shut down in Tokyo accounts for 21% of the total production in Japan, the lockdown would result in a reduction of the daily production in Japan by 86% in a month.
这项研究量化了为防止新冠病毒传播而可能封锁东京的经济影响。由于供需紧张,封锁的负面影响可能会通过供应链传播到其他地区。我们将基于代理的模型应用于日本近160万家公司的实际供应链,模拟了东京以外地区的生产活动在东京市民生存不重要的生产活动关闭一段时间后会发生什么。我们发现,当东京被封锁一个月时,对其他地区的间接影响将是对东京的直接影响的两倍,导致日本的总产量损失27万亿日元,相当于其年GDP的5.3%。虽然东京的产量占日本总产量的21%,但封锁将导致日本的日产量在一个月内减少86%。

Abstract: The existence of externalities in fact makes it impossible to measure social costs and social well-being by market means. The solution of many urban problems demands an integrated approach. Urban economy is crucial domain where externalities disrupt efficiency and make it difficult reach prompt decisions. It is essential to pay attention to the function of a city and its spatial organization. Traditional economic theory fails to consider the externalities arising from the interaction of three city spheres: economic, ecological and social. The choice between environmental and social well-being is a very acute issue. The access to high-paying jobs and the availability of social benefits is associated in Russia with living or moving to cities or regions with an unfavorable environment. Authors have tried to find an efficient city size (in terms of population) for 114 Russian towns considering all three spheres and demonstrated how to achieve an efficient city size by means of ecological regulation and changes in city area.
摘要:外部性的存在使得用市场手段衡量社会成本和社会福利成为不可能。许多城市问题的解决需要采取综合办法。城市经济是外部性干扰效率、难以迅速做出决策的重要领域。重视城市的功能和空间组织是城市发展的关键。传统的经济理论没有考虑城市经济、生态和社会三个领域相互作用所产生的外部性。环境福利和社会福利之间的选择是一个非常尖锐的问题。在俄罗斯,获得高薪工作和社会福利与居住或迁移到环境不利的城市或地区有关。作者试图为114个俄罗斯城镇找到一个有效的城市规模(按人口计算),考虑到这三个领域,并展示了如何通过生态调节和城市面积的变化来实现一个有效的城市规模。
