碳中和愿景的实现路径与政策体系

习近平主席在第七十五届联合国大会上郑重承诺中国将努力争取2060年实现碳中和目标，为中国未来低碳转型促进经济高质量发展、生态文明建设指明了方向、明确了目标，也提振了全球应对气候变化的信心。作为排放量全球最大的发展中国家，在2030年前达峰后用三十年左右的时间很快地实现碳中和愿景，任务异常艰巨，但总体上排放路径必然呈现尽早达峰、稳中有降、快速降低、趋稳中和的过程。支撑碳中和的技术几乎涉及所有的产业和经济活动，从控制碳排放途径的角度可以分为高能效循环利用技术、零碳能源技术、负排放技术。政府、企业、个人在迈向碳中和愿景进程中具有至关重要而又各有侧重的作用，需要科学的政策体系以形成系统有效的激励机制，促进资本和人才朝着碳中和技术创新和市场化推广应用方向快速汇集。     

我国县级地区生活垃圾焚烧设施环境社会风险分析及应对策略研究——基于31省份设施负荷率与网络舆情的分析

在政策支持和实际需求的驱动下,可能会导致县级地区垃圾焚烧项目迅速增多,且带来潜在的环境监管压力和环境社会风险,需要给予持续的特别关注,并对地方做好环境监管和风险管控的指导。本文基于全国精细化的生活垃圾焚烧处理设施、生活垃圾产生量、网络舆情等数据,通过构建泰森多边形等空间分析方法进行了焚烧处理设施的服务范围识别及负荷率计算,通过自然语言处理技术进行了关于生活垃圾焚烧处理设施的情感分析。在此基础上,基于焚烧处理设施的负荷率和负面舆情比例,对31个省份环境社会风险进行定量的评估分析并提出对策建议,一是平衡解决“缺口大”和“吃不饱”问题,合理规划布局县级地区生活垃圾焚烧处理设施;二是聚焦负面舆情高发领域、区域,积极防范县级地区生活垃圾焚烧处理设施环境社会风险。     

现代能源生态系统建设:一种理论探讨

在现代社会发展中,能源资源开发和利用所产生的巨大极化效应使整个人类可持续发展面临越来越严重的挑战。论文应用工业生态学的观点对能源系统的建设进行重新认识,提出了“能源生态系统”的概念;阐述了能源生态系统的3个组成部分:内生系统,外生系统,共生系统;并探讨了其空间结构的类型划分和基本形态。论文建立的现代能源生态建设基本框架,为进一步开展此方面的理论探讨提供有益借鉴。     

1615—1619年中国蝗灾时空演化及环境背景研究

基于对历史文献资料的梳理,针对1615—1619年我国发生的重大旱、蝗、涝等群发灾害,以蝗灾为主线,复原蝗灾事件的时空演化过程,解析其发生的气候背景和社会响应。结果表明：（1）蝗灾事件呈现五年的发生发展衰亡周期,县次波动明显,1616和1617年为峰值年份;（2）蝗灾以中、高等级发生为主,核心区域为黄淮海平原,热点地区为山东、河南、安徽等;空间上呈现“北密南疏”、“北方主导”的分布格局;（3）蝗与旱、涝的空间叠加显示,旱-蝗组合集中分布于黄淮海平原及其毗邻地区,涝-蝗组合则呈零星分布,旱蝗并发的频次高于涝蝗,旱蝗关系更紧密;（4）蝗灾频发与大发伴生饥荒、疫灾,体现了灾异的时空传递与承继,且次生灾害的出现存在滞后效应;（5）在寒冷期,蝗灾与温度呈现正相关,与降水呈现负相关。

介绍了定量风险评价的风险可接受准则和石油化工企业定量风险评价的一般程序。基本程序主要包括准备、资料数据收集、危险辨识、失效频率分析、失效后果分析、风险计算、风险评价及建议和风险评价报告和结论。此外,提出了评价过程中应注意的事项。     

用于组织和产品碳足迹的中国电力温室气体排放因子

讨论了组织和产品碳足迹与清洁发展机制(CDM)在计算电力温室气体排放因子方法上的区别,在发改委电力排放因子的基础上进行了多项修正与补充,分别得到用于组织和产品碳足迹的中国电力温室气体排放因子.结果表明,发改委发布的电力基准线排放因子与本文得出的组织和产品碳足迹的排放因子有显著差距,不应混用.本文计算的排放因子可为国内组织及产品碳足迹研究提供更恰当的数据来源.     

Five lessons to guide more effective biodiversity conservation message framing

Communication and advocacy approaches that influence attitudes and behaviors are key to addressing conservation problems, and the way an issue is framed can affect how people view, judge, and respond to an issue. Responses to conservation interventions can also be influenced by subtle wording changes in statements that may appeal to different values, activate social norms, influence a person's affect or mood, or trigger certain biases, each of which can differently influence the resulting engagement, attitudes, and behavior. We contend that by strategically considering how conservation communications are framed, they can be made more effective with little or no additional cost. Key framing considerations include, emphasizing things that matter to the audience, evoking helpful social norms, reducing psychological distance, leveraging useful biases, and, where practicable, testing messages. These lessons will help communicators think strategically about how to frame messages for greater effect.     

Ethical considerations when conservation research involves people

Social science is becoming increasingly important in conservation, with more studies involving methodologies that collect data from and about people. Conservation science is a normative and applied discipline designed to support and inform management and practice. Poor research practice risks harming participants and, researchers, and can leave negative legacies. Often, those at the forefront of field-based research are early-career researchers, many of whom enter their first research experience ill-prepared for the ethical conundrums they may face. We draw on our own experiences as early-career researchers to illuminate how ethical challenges arise during conservation research that involves human participants. Specifically, we considered ethical review procedures, conflicts of values, and power relations, and devised broad recommendations on how to navigate ethical challenges when they arise during research. In particular, we recommend researchers apply reflexivity (i.e., thinking that allows researchers to recognize the effect researchers have on the research) to help navigate ethical challenges and encourage greater engagement with ethical review processes and the development of ethical guidelines for conservation research that involves human participants. Such guidelines must be accompanied by the integration of rigorous ethical training into conservation education. We believe our experiences are not uncommon and can be avoided and hope to spark discussion to contribute to a more socially just conservation.     

Corporate Environmental Responsibility and Global Online Cross-sector Alliance Network: A Cross-national Study

With the rise of global environmental issues and the emerging trend of corporate social responsibility (CSR) and corporation–non-governmental organization (NGO) alliances, organizations are developing collaborative alliances across sectors and nations to address environment problems. An international perspective is needed to explain the global structure of cross-sector alliance networks and the divergence or similarity of CSR communication across nations. This exploratory study draws insights from the national business systems (NBS) approach and applies social network analysis to examine the cross-sector alliance network among Global 500 Fortune corporations and 441 environmental international NGOs. Findings suggest that (1) an NBS approach to CSR can explain the network structural features of a cross-sector alliance network; (2) political context and national education level strongly predict green partnerships; and (3) regional differences are apparent in the global network, with Asian corporations lagging behind in cross-sector alliance building.
