Managing carbon emissions in China through building energy efficiency   总被引:1,自引:0,他引:1  
This paper attempts to analyse the role of building energy efficiency (BEE) in China in addressing climate change mitigation. It provides an analysis of the current situation and future prospects for the adoption of BEE technologies in Chinese cities. It outlines the economic and institutional barriers to large-scale deployment of the sustainable, low-carbon, and even carbon-free construction techniques. Based on a comprehensive overview of energy demand characteristics and development trends driven by economic and demographic growth, different policy tools for cost-effective CO2 emission reduction in the Chinese construction sector are described. We propose a comprehensive approach combining building design and construction, and the urban planning and building material industries, in order to drastically improve BEE during this period of rapid urban development. A coherent institutional framework needs to be established to ensure the implementation of efficiency policies. Regulatory and incentive options should be integrated into the policy portfolios of BEE to minimise the efficiency gap and to realise sizeable carbon emissions cuts in the next decades. We analyse in detail several policies and instruments, and formulate relevant policy proposals fostering low-carbon construction technology in China. Specifically, Our analysis shows that improving building energy efficiency can generate considerable carbon emissions reduction credits with competitive price under the CDM framework.  相似文献

Most developing countries, particularly Indonesia, will be facing problems of sludge pressure in the next decades due to the increase in practices of legal and illegal logging as well as land and water demands. Consequently, they will also be facing the challenges of soil erosion and sludge management due to increased quantities of sludge coming from several potential sources, such as activated sludge, chemical sludge, fecal sludge and solid wastes as well as erosion and sedimentation. Although the government of Indonesia has enacted laws and policies to speed up the implementation of the programs and activities related to sludge management, the detailed practice concepts in implementing the programs need to be identified. Discussion of role-sharing amongst the related government agencies, private institutions and other stakeholders is urgent for clarifying the participation of each party in the next years to come. This paper proposes a management approach and level of responsibilities in sludge management. Implementation of zero ΔQ, zero ΔS and zero ΔP policies needs to be adopted by local and central governments. Application of sludge on the agricultural lands and other uses will promote sustainable development.  相似文献

Waste disposal is an issue that is becoming increasingly important in policy terms in the European Union, and in Italy, a country showing strong geographical heterogeneity in waste management. This paper analyses the process of decoupling/delinking between economic growth and landfilling trends in a framework where economic, policy, geographical elements and spatial issues are all considered as drivers behind the phenomenon. We exploit an original and very rich provincial panel dataset over 1999–2005 for the 103 Italian provinces. Evidence shows that the observed ‘absolute’ decoupling between economic growth and landfilling is driven by a mix of structural factors. Among the main factors, population density, more than the provincial income level, emerges as a crucial driver: local opportunity costs and landfill externalities matter in shaping waste policies and local commitment to a transition away from landfilling of waste (landfill diversion). However, not only structural factors are relevant. If on the one hand landfill taxes are not a significant driver of the phenomenon, waste management tools, such as separated collection for recycling, and the tariff system connected to waste services, bring about significant effect on the amount of landfilled waste. Moreover, regarding the analysis of spatial interrelations across provinces, we note that the presence of incinerators in nearby provinces increases landfill diversion, due probably to free riding behaviour or intra-provinces ‘agreements’ on waste management; this is not true for nearby landfill sites, that cause for a given province a strong lock in effect. Future research could strengthen the analysis of policy effectiveness at regional level, focusing on policy endogeneity, and the full investigation of spatial correlations in waste disposal performances.  相似文献

This paper empirically estimates the economic impacts of a large-scale public investment in natural infrastructure aimed at adapting to climate change and increasing coastal resilience. I utilize temporal and spatial variation in investment in dunes to provide a hedonic property value estimate of the economic benefits. I identify the net effect of treatment utilizing the doubly robust Oaxaca-Blinder estimator and show that coastal housing price increases attributable to constructed dunes are approximately 3.6%. A decomposition of the average impact suggests that the policy intervention generates ancillary costs related to impaired ocean views and privacy concerns that partially offset large protection benefits.  相似文献

Policies on economic use of natural resources require considerations to social and cultural values. In order to make those concrete in a planning context, this paper aims to interpret social and cultural criteria, identify indicators, match these with verifier variables and visualize them on maps. Indicators were selected from a review of scholarly work and natural resource policies, and then matched with verifier variables available for Sweden’s 290 municipalities. Maps of the spatial distribution of four social and four cultural verifier variables were then produced. Consideration of social and cultural values in the studied natural resource use sectors was limited. The spatial distribution of the verifier variables exhibited a general divide between northwest and south Sweden, and regional rural and urban areas. We conclude that it is possible to identify indicators and match them with verifier variables to support inclusion of social and cultural values in planning.  相似文献

Olympic shooters discharge, annually, thousands of tons of lead shot which pose toxic risks to animals and may pollute both surface and ground waters. Non-toxic steel shot is an acceptable and effective substitute, but International Shooting Sports Federation (ISSF) rules prevent its adoption. The present policy and rules of the ISSF on lead shot use contravene the International Olympic Committee (IOC) Charter position on environmental protection. The United Nations Environment Programme (UNEP), a formal Olympic partner on environmental protection, has no stated policy on contamination from lead ammunition, despite having declared lead a Priority Area for remedial action, and is pressing to remove lead from the global human environment. The IOC Sport and Environment Commission and UNEP could examine the continued use of lead shot ammunition and advise the IOC Executive Board on appropriate changes in policy and rules that could halt the massive lead shot contamination of shooting range environments world-wide.  相似文献

由于计划生育国策的实行,中国在总体人口基数得到控制的同时面临人口红利消失殆尽的现状。推行二孩政策,对缓解因第一次人口红利消失而产生的社会经济矛盾意义重大,并为第二次人口红利的发展提供契机。通过对比分析二孩政策实施前后人口红利效应,对更为客观地认识政策实质,保障政策落实,进而推动人口红利的可持续发展,具有必要性和现实意义。本文运用PADISINT人口预测软件预测了中国未来一定时期的抚养比,分析了生育政策调整实施将会产生的人口红利效应。结果表明:1二孩政策的实行对"储蓄率"及"城镇化率"的提升具有促进作用;2在城市,二孩政策的人口红利效应主要通过提升劳动年龄段的人口数量体现;在农村,则主要通过推动性别比的均衡发展体现;3在城市及农村均缺乏鼓励生育二孩的配套政策;4二孩政策的生效具有滞后性;5第二次人口红利的契机难以把握。结合本文预测结果,2050年,老年抚养比高达51.45%,为使人口红利效应得到更为充分的发挥,需要进一步补充、完善现有制度,鼓励生育二孩;注重教育,特别是针对农村女孩的高等教育,提高人口"质量"以弥补"数量"缺失;合理引导老龄人群消费观、投资观、从业观的调整,逐步营造"养老"与"生育"相辅相成的可持续性社会环境。  相似文献

Environmental insurance policies and the success of claims brought under them depend upon the intersection of both the legal and technical issues involved. The evolution of environmental insurance policies, from their origin in the Commercial General Liability policies up to the creation of new insurance products designed to cover specifically environmental concerns are addressed in this work. Both scientists and attorneys will have to develop a fuller understanding of environmental damage and assessments. The intent of this article is to provide a starting point for members of both disciplines in their quest for a fuller understanding of the legal and technical issues involved in environmental claims.  相似文献

The spatial and temporal repercussions of climate change are of an extremely complex nature. Coping with climate change is, first and foremost, a challenge to political decision making and, considering the long-term effects of the climate system, to planning. However, there have never been more doubts that the political-administrative system is able to meet these requirements. Although much evidence has been put forward in favor of such skepticism, sometimes, it is dangerous to overstate the existing limits. Drawing on two case studies in the area of flood risk management in Germany, the article illustrates how and why significant path change came about. In both cases, the state proved to still being a pivotal actor, due to a number of functions that cannot be assumed by other actors. However, other actor groups—such as actors from science, the media, NGOs, and citizen groups—play a significant role as well by providing relevant expertise and influencing the public discourse, thus mobilizing significant political pressure.  相似文献

European forest policymaking is shaped by progressing European integration, yet with notable ideological divisions and diverging interests among countries. This paper focuses on the coalitional politics of key environmental forest issues: biodiversity conservation, timber legality, and climate protection policy. Combining the Advocacy Coalition Framework and the Shifting Coalition Theory, and informed by more than 186 key informant interviews and 73 policy documents spanning a 20-year timeframe, we examine the evolution of coalitional forest politics in Europe. We find that the basic line-up has remained stable: an environmental coalition supporting EU environmental forest policy integration and a forest sector coalition mostly opposing it. Still, strategic alliances across these coalitions have occurred for specific policy issues which have resulted in a gradual establishment of an EU environmental forest policy. We conclude with discussion of our findings and provide suggestions for further research.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01644-5.  相似文献
