The gap report of global climate change mitigation,finance, and governance after the United States declared its withdrawal from the Paris Agreement

On 1 June 2017, the US President Donald Trump officially announced the withdrawal from the Paris Agreement, thus the study on the reasons of withdrawal, the potential impacts, and coping strategies has become a focus among policy circles and of the international community. Based on the self-developed US Policy Assessment Model, this paper systematically evaluates the three potential “major deficits” in terms of mitigation, climate finance, and global climate governance, as a result of the US withdrawal from the Paris Agreement and puts forward policy suggestions for coping with such transformations accordingly. The study shows that the United States ’withdrawal from the Paris Agreement will affect the existence and implementation of successive climate policies and result in an additional 8.8–13.4% increase in the global emissions reduction deficit. The United States’ withdrawal will also deteriorate the existing climate finance mechanism. The Green Climate Fund (GCF)’s funding gap will increase by US$2 billion, while the gap of long-term climate finance will increase by about US$5 billion a year. Either the China–EU or the “BASIC plus” mechanism could fill the governance deficit caused by the United States and the lack of political momentum may continue for a while in the future.     

Competition gives way to cooperation:rethinking Sino-Indian relations in climate change negotiations

In global climate change politics,China and India have worked closely with each other,representing two big emitters from the developing world.This article reviews Sino-Indian cooperation during four UN climate change negotiations from 2009 to 2012.Their collaboration echoed the perception of neorealism in international relations(IR) studies that states will seek external balancing for maximizing national relative gains.China and India are expected to continue their cooperation on climate change issues when sharing the same structural position as big economies and big emitters,the same pressure in carbon emission reductions,and the same goal of improving living standards for their citizens.Encountering the devastating impacts of climate change and the deadlock in responsibility division in current global climate change governance,this work seeks to shed light on the evolving multilateral governance environment and its complex implications for Sino-Indian relations from an IR perspective.     

A social and ecological imperative for ecosystem-based adaptation to climate change in the Pacific Islands

Climate change is predicted to have a range of impacts on Pacific Island ecosystems and the services they provide for current and future development. There are a number of characteristics that can make adaptation approaches that utilise the benefits of ecosystems a compelling and viable alternative to other adaptation approaches. The objective of this paper is to determine what level of relative influence technical and planning considerations currently have in guiding the recognition and application of ecosystem-based adaptation (EbA) approaches in the Pacific Islands context. The technical feasibility of EbA in relation to the expected impacts of climate change and the compatibility of adaptation planning processes of the Pacific Islands with EbA requirements was considered. The main barrier to fully implementing EbA in the Pacific Islands is not likely to be financial capital, but a combination of stable technical capacity within government departments to advise communities on EbA opportunities and the compatibility of planning frameworks.     

The challenges of water,waste and climate change in cities

Cities play a prominent role in our economic development as more than 80 % of the gross world product (GWP) comes from cities. Only 600 urban areas with just 20 % of the world population generate 60 % of the GWP. Rapid urbanization, climate change, inadequate maintenance of water and wastewater infrastructures and poor solid waste management may lead to flooding, water scarcity, water pollution, adverse health effects and rehabilitation costs that may overwhelm the resilience of cities. These megatrends pose urgent challenges in cities as the cost of inaction is high. We present an overview about population growth, urbanization, water, waste, climate change, water governance and transitions. Against this background, we discuss the categorization of cities based on our baseline assessments, i.e. our City Blueprint research on 45 municipalities and regions predominantly in Europe. With this bias towards Europe in mind, the challenges can be discussed globally by clustering cities into distinct categories of sustainability and by providing additional data and information from global regions. We distinguish five categories of sustainability: (1) cities lacking basic water services, (2) wasteful cities, (3) water-efficient cities, (4) resource-efficient and adaptive cities and (5) water-wise cities. Many cities in Western Europe belong to categories 3 and 4. Some cities in Eastern Europe and the few cities we have assessed in Latin America, Asia and Africa can be categorized as cities lacking basic water services. Lack of water infrastructures or obsolete infrastructures, solid waste management and climate adaptation are priorities. It is concluded that cities require a long-term framing of their sectoral challenges into a proactive and coherent Urban Agenda to maximize the co-benefits of adaptation and to minimize the cost. Furthermore, regional platforms of cities are needed to enhance city-to-city learning and to improve governance capacities necessary to accelerate effective and efficient transitions towards water-wise cities. These learning alliances are needed as the time window to solve the global water governance crisis is narrow and rapidly closing. The water sector can play an important role but needs to reframe and refocus radically.     

《巴黎协定》时代的气候融资:全球进展、治理挑战与中国对策

本文首先辨析了"气候资金"与"气候融资"两个基本概念,且通过对包括《巴黎协定》在内,最新的气候资金相关法律文件、信息通报、文献资料、智库报告的研究和系统梳理,指出全球气候融资发展趋势表现在全球气候融资缺口正在持续扩大;资金来源更加市场化;发展金融机构募集、管理和分配了大部分的公共资金;新型经济体用款权受到挤压,也呈现出更大的出资潜力;稳定的碳价格被认为是全球实现"零排放"长期减排目标的核心机制。与此同时,气候资金治理体系也处在关键的转型期,目前气候资金治理正在向"自下而上"的模式过渡,《公约》外平台承担了"气候风险主流化"的多重功能,但需要警惕"自下而上"的治理模式有绕过"共同但有区别责任"的风险,且绿色气候基金运作规则的导向性作用值得关注。据此,本文在最后提出了一系列治理建议。建议我国应积极影响国际气候资金机制运营规则和技术规则的制定,避免发达国家以及代表其利益的国际组织制定的标准片面地发展为国际规则;支持在全球设定渐进的、可预测的、可信的碳价格,并且肯定将气候与环境风险因素内生化的核心思想理念;与绿色气候基金开展多方位合作,推动气候公共资金治理规则转型;加强与世界银行在气候融资领域的合作;借G20平台逐步发展为气候融资政策突破和工具创新的引领者。     

Mediterranean agriculture under climate change: adaptive capacity, adaptation, and ethics

In the coming decades, the Mediterranean region is expected to experience various climate impacts with negative consequences on agricultural systems and which will cause uneven reductions in agricultural production. By and large, the impacts of climate change on Mediterranean agriculture will be heavier for southern areas of the region. This unbalanced distribution of negative impacts underscores the significance and role of ethics in such a context of analysis. Consequently, the aim of this article is to justify and develop an ethical approach to agricultural adaptation in the Mediterranean and to derive the consequent implications for adaptation policy in the region. In particular, we define an index of adaptive capacity for the agricultural systems of the Mediterranean region on whose basis it is possible to group its different sub-regions, and we provide an overview of the suitable adaptation actions and policies for the sub-regions identified. We then vindicate and put forward an ethical approach to agricultural adaptation, highlighting the implications for the Mediterranean region and the limitations of such an ethical framework. Finally, we emphasize the broader potential of ethics for agricultural adaptation policy.     

The uncertainty of climate sensitivity and its implication for the Paris negotiation

Uncertainty of climate sensitivity is one of the critical issues that may affect climate response strategies. Whereas the equilibrium climate sensitivity (ECS) was specified as 2–4.5 °C with the best estimate of 3 °C in the 4th Assessment Report of IPCC, it was revised to 1.5–4.5 °C in the 5th Assessment Report. The authors examined the impact of a difference in ECS assuming a best estimate of 2.5 °C, instead of 3 °C. The current pledges of several countries including the U.S., EU and China on emission reductions beyond 2020 are not on track for the 2 °C target with an ECS of 3 °C but are compatible with the target with an ECS of 2.5 °C. It is critically important for policymakers in Paris to know that they are in a position to make decisions under large uncertainty of ECS.     

Social participation and climate change

Social participation has been broadly analysed by comparing case studies of different types of socio-economic developments in Brazil and the United Kingdom (UK). A key objective has been to consider how effective social participation has been in incorporating society’s points of view in the decision making process. In most cases, it would appear that very little can be done by stakeholders to change big decisions on development policies that support public and private development because in reality social participation often only provides an opportunity for discussion and agreement on specific issues regarding how development will be undertaken and how stakeholders will be affected. Although Brazil and the United Kingdom have socio-economic and cultural differences, it is necessary to emphasize that education, self-organization and knowledge of civil rights are crucial for an effective social participation process. As climate change is an important topic for present and future generations and that some of the development activities analysed in this study will emit greenhouse gases, this study also attempts to investigate if climate change mitigation strategies have been integrated into the social participation process. Investigation shows that there is little evidence that climate change mitigation actions involving stakeholders have been integrated into development strategies or have been part of social participation schemes in the case studies analysed. Having said that, the study also describes positive examples of climate change mitigation actions in different parts of the world that involve local people in ‘carbon-neutral’ or ‘social-carbon’ projects and proposes the creation of a carbon-neutral committee that would be responsible for coordinating climate change mitigation measures within development proposals such as the ones analysed in this study.

Climate hotspots: key vulnerable regions,climate change and limits to warming

This paper reviews scientific and gray literature addressing climate change vulnerability and adaptation in the Inuvialuit Settlement Region (ISR) in the western Canadian Arctic. The review is structured using a vulnerability framework, and 420 documents related directly or indirectly to climate change are analyzed to provide insights on the current state of knowledge on climate change vulnerability in the ISR as a basis for supporting future research and long-term adaptation planning in the region. The literature documents evidence of climate change in the ISR which is compromising food security and health status, limiting transportation access and travel routes to hunting grounds, and damaging municipal infrastructure. Adaptations are being employed to manage changing conditions; however, many of the adaptations being undertaken are short term, ad-hoc, and reactive in nature. Limited long-term strategic planning for climate change is being undertaken. Current climate change risks are expected to continue in the future with further implications for communities but less is known about the adaptive capacity of communities. This review identifies the importance of targeted vulnerability research that works closely with community members and decision makers to understand the interactions between current and projected climate change and the factors which condition vulnerability and influence adaptation. Research gaps are identified, and recommendations for advancing adaptation planning are outlined.     

《巴黎协定》后的气候资金测量、报告和核证体系构建研究

气候资金测量、报告和核证产生于《联合国气候变化框架公约》(简称《公约》)之下,2009年以来一直是全球气候谈判的重点之一,也是未来全球共同应对气候变化和不断增进国际信任的重要环节。《巴黎协定》达成的"每两年通报"的决定,将推动气候资金测量、报告和核证得到不断的加强和完善。本文通过梳理最新的气候资金机制以及测量、报告和核证的文献资料和智库报告,分析了气候资金测量、报告和核证的内涵、目标和最新进展,以及公约框架下面临的挑战。分析指出,目前不同的气候资金统计和核算机构的资金分类标准存在差异,数据可比性有待改善;缺乏从资金上游到下游的反馈机制,影响气候资金测量、报告和核证体系的完整性;气候资金计量体系虽然正在发展和完善之中,但仍然难以提供准确的资金"支付"数据。据此,文章提出了构建综合性的国际气候资金测量、报告和核证体系的重点任务:建立具有统一数据基础和核算口径的气候资金测量体系,建立操作指南更为详细、形式更为标准统一的气候资金报告体系,以及"自上而下"和"自下而上"相结合的气候资金核证机制。最后,文章指出国际气候资金测量、报告和核证体系的构建需要发达国家和发展中国家在坚持公约资金机制的基础上共同参与和协作。作为国际上少数几个向GEF捐资的发展中国家之一,中国在参与过程中应力争体现发展中国家对气候资金性质的主张以及对测量、报告和核证机制的关键概念和范围界定的主张,影响国际气候资金机制的运营规则和技术规则。     

国外学术界对《巴黎协定》的评价及履约前景分析

2016年《巴黎协定》的正式生效是全球环境治理的重要里程碑,是国际社会在应对气候变化的艰难进程中迈出的重要一步,标志着全球环境治理从此进入履约阶段。本文基于宾夕法尼亚大学智库与公民社会项目(TTCSP)公布的《2015年全球智库指数报告》,选取其中排名前十位的国际环境智库的研究报告和环境领域中代表性学者的相关论文,对国外学术界有关《巴黎协定》履约前景的分析进行了系统梳理,并对此做出简要评述。文章在肯定《巴黎协定》有力推进国际气候治理进程的同时,也指出在新的国际形势之下,尤其是在英国正式启动脱欧进程和特朗普新任美国总统后,其履约过程中更是存在着协定之内和协定之外的众多挑战和不确定性,本文的基本结论如下:首先,协定之内面临着协定缔约方国内批准程序上的挑战;国家自主贡献的实现与发展中国家能力建设;2℃温升目标的实现前景;审评和盘点的效力评估;碳市场机制能否有效运行。其次,协定之外面临着英国脱欧的潜在气候政策变化及影响;美国气候政策的可能变化及其影响。基于对以上智库报告和相关研究论文的分析,笔者对《巴黎协定》的履约前景得出几点看法:(1)正视国际气候合作的机遇与挑战;(2)对具体议题的落实需充满信心;(3)理性冷静看待英美气候政策的可能变化;(4)鼓励环境类国际组织之外的非国家行为体展开通力合作。对此,我们应正视履约中的挑战与不确定性,做好充分的应对之策,确保履约进程的顺利完成。总之,《巴黎协定》的履约前景不容乐观,国际社会任重道远。     

Small island developing states: coastal systems, global change and sustainability

The intent of this paper is to place the concepts of exposure, vulnerability, resilience and risk in the context of the consequences of global change for the sustainable development of small island developing states (SIDS). Many such states face a number of global climate change risks, such as an increase in the proportion of more intense storms, along with other global change threats that include energy security and costs. All these threats come on top of local development threats, such as increased run-off, often with increasing levels of contaminants due to unsustainable agricultural and industrial practices. When taken together, the resulting pressures on islands and their communities lead to significant increases in vulnerability to change due to reduced resilience to these changes. Vulnerability is also increasing as a result of contemporary processes that heighten the exposure of material and other assets. The capacity to address hazard risk also influences vulnerability. This includes the level of awareness of coastal hazards and exposure, and access to critical life support infrastructure, especially for people living in hazard-prone areas. Vulnerability and resilience are considered to be important integrating concepts when managing the local consequences of global changes. There are many initiatives that will help reduce the vulnerability and enhance the resilience of SIDS to such changes. These include improving risk knowledge and coastal resource and land use management, while also strengthening socio-economic systems and livelihoods. In this way, managing global change can be closely aligned with local development and humanitarian processes, thereby enhancing the overall sustainability of development processes and outcomes.     

Australian agriculture: coping with dangerous climate change

Australian agriculture has operated successfully in one of the world’s most hostile environments for two centuries. However, climate change is posing serious challenges to its ongoing success. Determining what might constitute dangerous climate change for Australian agriculture is not an easy task, as most climate-related risks are associated with changes in the highly uncertain hydrological cycle rather than directly to more predictable changes in temperature. In addition, the adaptive capacity of Australian producers is generally high, as they have had to cope with a highly variable climate in which periodic, severe droughts are the norm. As the underlying global trends in climate interact with the continent’s patterns of natural variability, producers can generally deal with gradual changes in climate but are most concerned about high rates of change in regional and local climates and with abrupt, unexpected shifts in climate patterns. Perhaps the best indicator of dangerous climate change for Australian agriculture is the persistence, or not, of the drying trends in many of the Country’s most productive regions and the strength of the linkage between these trends and global climate change.
