丝绸之路经济带西南四省区温室气体排放核算及等级评估

为建设绿色丝绸之路提供决策参考,基于IPCC法和中国《省级温室气体编制指南》,核算了四川、重庆、云南、广西四省区的温室气体排放清单,并进行了动态分析和排放等级评估。结果表明:2000～2013年四省区温室气体排放总量呈快速增长趋势,其中CO_2排放比例最高,其次是N_2O和CH_4。能源消费是温室气体排放的主要来源,其中又以煤炭贡献量最大。林业固碳的增长速度赶不上温室气体排放的增长速度,且林业固碳能力增长不明显。人均和单位面积温室气体排放量均呈不断增长趋势,且高于全球承担减排义务与应对气候变化的目标,减排任务仍然非常艰巨。四省区GHG排放指数均呈不断增长趋势,排放等级四川、云南和广西均由较低(Ⅰc)上升为中下(Ⅱa);重庆由中下(Ⅱa)上升为较高(Ⅲa)。

加拿大油气系统温室气体逃逸排放清单简述

油气系统温室气体逃逸排放是温室气体排放清单的重要组成部分。加拿大在清单中统一考虑了油气系统可能存在的温室气体排放源,因此清单中不仅包括了温室气体的逃逸排放(泄漏、排空),还考虑了能源燃烧中的气体排放,所考虑的温室气体种类既包括甲烷,也包括二氧化碳。采用的是政府间气候变化专门委员会(IPCC)第三层次方法(Tier3),即设备清单法、操作时间法和活动水平法三种计算方法,详细地将排放源分类进行估算。该国对数据的管理、质量控制和质量评估、不确定性分析以及在如何保证数据的持续性方面的作法都值得我们学习和借鉴。     

大气温室效应及其能源对策

由于温室气体(指 CO_2、CH_4、N_2O、O_3、氯氟烃等共约30多种)在大气底层中不断增加,使地表热外流受阻,从而造成温度升高,象在玻璃温室中的情形一样,故称温室效应。监测表明,近十年来,大气中 CO_2浓度增长幅度为25％,达350ppm,照现增长速度到21世纪末可达600ppm。(据统计,人为排放 CO_2量达200亿吨/年,主要是燃料煤、石油、天然气和生物质能燃料如薪炭、秸秆、动物粪便的结果)。CO_2是造成温室效应的主导气体,其增长后果是气温升高,这将使两极冰帽融化,海面

我国生活垃圾无害化向减量化处理处置转换路径探析

对比发达国家与发展中国家生活垃圾减量化处理处置经验，本文运用制度分析、统计分析等手段探究我国即将经历的生活垃圾减量化处理处置阶段转换问题。研究发现：①以政府公共投资和无害化处理处置为主要特征的生活垃圾处理处置I阶段解决垃圾围城的方式行将结束，减量化程度逐渐提高和社会资本的进入是II阶段的主要表现形式。②从我国生活垃圾处理处置的发展脉络看，促使I阶段向II阶段转化的主导因素包括城市化速度的加快、国家供给侧结构性改革促使源头减量和公共财政投入向市场投入转化等。③考虑到我国各地生活垃圾处理处置和经济发展实际，应改变现有生活垃圾处理处置管理体系，确立企业的源头减量主体地位；提高生活垃圾分类回收比例，改善中端减量化效率；以无废城市建设为契机，推进生活垃圾全域减量；重塑经济与发展的联系，借助市场化力量推进资源与经济增长联系从数量关系向强价格关系转化。     

Carbon accounting rules and guidelines for the United States forest sector

The United States Climate Change Initiative includes improvements to the U.S. Department of Energy's Voluntary Greenhouse Gas Reporting Program. The program includes specific accounting rules and guidelines for reporting and registering forestry activities that reduce atmospheric CO2 by increasing carbon sequestration or reducing emissions. In the forestry sector, there is potential for the economic value of emissions credits to provide increased income for landowners, to support rural development, to facilitate the practice of sustainable forest management, and to support restoration of ecosystems. Forestry activities with potential for achieving substantial reductions include, but are not limited to: afforestation, mine land reclamation, forest restoration, agroforestry, forest management, short-rotation biomass energy plantations, forest protection, wood production, and urban forestry. To be eligible for registration, the reported reductions must use methods and meet standards contained in the guidelines. Forestry presents some unique challenges and opportunities because of the diversity of activities, the variety of practices that can affect greenhouse gases, year-to-year variability in emissions and sequestration, the effects of activities on different forest carbon pools, and accounting for the effects of natural disturbance.     

Environmental and resource sustainability of Chinese cities: A review of issues,policies, practices and effects

This paper synthesizes the English literature on current issues, policies and practices, and their effects on environmental and resource sustainability in China's ongoing urbanization. Aspects of urban sustainability reviewed include air, water, solid waste, energy efficiency, transportation and land use. It shows that Chinese cities have been and probably will continue to be struggling with issues such as air pollution, scarcity of clean water, solid waste and greenhouse gas emissions. But there are many opportunities for improvement. It suggests shortages of existing policies and major gaps in knowledge and practice, which can be helpful to policy makers, planners and researchers in China and other developing countries.     

城市生活垃圾处理能力提升的驱动因素研究——基于2004—2020年30个省份的实证分析

提升末端生活垃圾处理能力，走出城市“垃圾围城”之困，一直是地方政府关切的核心议题。为探究城市生活垃圾处理能力的影响因素及其时空差异，从“政府能力系统”视角出发，围绕需求驱动、经济驱动、政策驱动、技术驱动四个维度，提出相关研究假设，并运用2004—2020年30个省份的面板数据进行实证检验。研究发现：生活垃圾清运量、人均GDP、地方环保支出、政策文本出台数量、无害化处理厂数量以及市容环卫专用车辆数均对城市生活垃圾处理能力的提升具有促进作用。在时间变化上，2004—2007年为生活垃圾处理能力初创阶段，受到经济、政策与技术驱动因素的显著影响； 2008—2016年为生活处理能力缓慢提升和局部发展阶段，持续受到技术驱动因素的显著作用；2017—2020年为处理能力全面提升阶段，需求、经济与技术因素均呈现出显著促进作用。在区域变化上，经济驱动的影响效应由东部向西部逐渐减弱，需求驱动、政策驱动因素只在东部地区影响显著，技术驱动因素对不同区域的生活垃圾处理能力均具有显著促进作用。最后，研究从源头减量、资金投入、政策倾斜与技术创新等方面，对促进中国城市生活垃圾处理能力的发展提供了相应的政策建议。     

Making cities resilient to climate change: identifying “win–win” interventions

Urbanisation is truly a global phenomenon. Starting at 39% in 1980, the urbanisation level rose to 52% in 2011. Ongoing rapid urbanisation has led to increase in urban greenhouse gas (GHG) emissions. Urban climate change risks have also increased with increase in climate-induced extreme weather events and more low-income urban dwellers living in climate sensitive locations. Despite increased emissions, including GHGs and heightened climate change vulnerability, climate mitigation and adaptation actions are rare in the cities of developing countries. Cities are overwhelmed with worsening congestion, air pollution, crime, waste management, and unemployment problems. Lack of resources and capacity constraints are other factors that discourage cities from embarking on climate change mitigation and adaptation pathways. Given the multitude of problems faced, there is simply no appetite for stand-alone urban climate change mitigation and adaptation policies and programmes. Urban mitigation and adaptation goals will have to be achieved as co-benefits of interventions targeted at solving pressing urban problems and challenges. The paper identifies administratively simple urban interventions that can help cities solve some of their pressing service delivery and urban environmental problems, while simultaneously mitigating rising urban GHG emissions and vulnerability to climate change.     

Estimating local greenhouse gas emissions—A case study on a Portuguese municipality

This paper describes the study that led to the development of a carbon dioxide emissions matrix for the Oeiras municipality, one of the largest Portuguese municipalities, located in the metropolitan area of Lisbon. This matrix takes into account the greenhouse gases (GHG) emissions, due to an increase of electricity demand in buildings as well as solid and liquid wastes treatment, from the domestic and services sectors.Using emission factors that were calculated from the relationship between the electricity produced and amount of treated wastes, the GHG emissions in the Oeiras municipality, were estimated for a time series of 6 years (1998–2003).The obtained results showed that the electricity sector accounts for about 75% of the municipal emissions in 2003. This study was developed in order to obtain tools to base options and actions to be undertaken by local authorities such as energy planning and also public information.     

垃圾分类收费推进我国城市垃圾分类收集的探讨

我国城市生活垃圾产生量逐渐增大，严重威胁人体健康及城市环境。分类收集是实现废弃物减量化、资源化、无害化的有效手段。我国城市生活垃圾分类收集状况不佳，大部分城市均为混合收集，给垃圾处理和城市环境带来了巨大压力。本文从国外发达国家城市生活垃圾分类收费促进生活垃圾分类收集的成功经验出发，提出几点推动我国垃圾分类的对策。
