基于环境保护的机动车税优化建议

当前区域性大气污染问题突出,机动车使用造成的污染问题不可忽视。为解决区域性的大气污染问题,机动车税费的污染减排调控功能日益被政府和学者重视。研究围绕"如何使机动车税更好发挥环境保护的效果"的问题,比较了中日机动车税的结构和性质,分析了在购买、保有和使用等不同环节的机动车税的特点以及环保效果,并基于问卷调查分析中国私家车主不同环节机动车税的负担情况。研究表明,在机动车使用环节征收的成品油消费税污染调控效果要优于其他环节的税收;对商业用途的机动车使用征税仅有收入功能没有调控功能,建议将机动车相关税的作用重心从购买环节转移到使用环节上,并对商业用途和私人用途的机动车实施差别税率。     

The marginal cost of public funds of mineral and energy taxes in Peru

We estimate the Marginal Cost of Public Funds (MCPF) for Peru using a detailed computable general equilibrium (CGE) model. Revenues from all major sources (including taxes on factors of production, natural resources such as energy and minerals, consumption, and imports) are examined. Our focus is on the efficiency implications of mineral and energy taxes, given their importance to Peruvian public finance. The primary data are from the Global Trade Analysis Project (GTAP) as modified to include detailed tax information from the Peruvian Ministry of Economy and Finance and the Peruvian Internal Revenue Service. Consistent with the theories of public finance, we find that the MCPF is greater for activities that face high or widely varying tax rates. The taxes on energy and mineral activities represent a clear illustration of this relationship. The results presented in this paper indicate opportunities to improved efficiency in the current tax mix, and also indicate the financing costs of proposed expenditures that would be funded with taxes on energy and natural resources.     

中国城市CO2排放和空气质量协同变化特征及驱动因素研究

城市既是受到气候变化和空气污染影响的重点区域,又是落实应对气候变化和大气污染防控政策的关键主体。在城市尺度上研究减污降碳政策的协同效应及其时空异质化的影响规律,将为因地制宜地制定减污降碳政策提供依据。本研究分析了2012—2019年我国284个地级市减污降碳协同效应指数的动态时空变化特征和规律;而后通过构建STIRPAT模型和地理时空加权回归（GTWR）模型,探讨了低碳政策、大气污染物防控政策、产业结构等驱动因素对减污降碳协同效应的时空异质化影响机制。结果表明：全国主要地级市耦合协调度指数平均值由2012年的0.79增加至2019年的0.85,环京津冀区域、汾渭平原等京津冀大气污染传输通道城市区域耦合协调度指数显著提高。以低碳试点城市为代表的区域,其降碳政策、减污政策、产业结构、人口规模、城镇化水平以及技术投入对减污降碳协同效应的影响存在显著的空间异质性。华北平原城市群作为大气污染防治的重点区域,主要通过减污政策提高协同效益;低碳政策主要在京津冀城市群、长江中游以及东南沿海地区城市发挥作用;中西部城市则主要通过产业结构调整、加大技术投入实现协同效益。最后,基于此提出促进城市减污降碳协同效益的对策建议。     

Local authorities and climate protection in the European union: Putting subsidiarity into practice?

Although intrinsically a global environmental concern, the climate change issue has a number of implications for local authorities. Within the European Union (EU), the remit of local authorities in—-for abatement policies—the crucial areas of energy and transport policy varies considerably, as does their commitment to environmental action more generally. This paper examines the role of local authorities in climate protection within a framework of global, EU and national action, through examples of local strategies from Germany, Italy, Spain, Sweden and the UK. The paper finds positive instances of action in all countries, but points to unsympathetic policy frameworks both at national and EU level, such as budget constraints imposed on local authorities, the pursuit of low energy prices combined with a resistance to impose carbon taxes, a lack of energy efficiency standards and insufficient support for public transport.

Taxing virgin natural resources: Lessons from aggregates taxation in Europe

The objective of this review paper is to analyze the efficiency of environmentally motivated taxes on virgin raw materials. We analyze both the economic-theoretical foundations of virgin natural resource taxation, and the empirical experiences of aggregates taxes i.e., taxes on, for instance, gravel, rock, stone, etc. in three European countries. These include Sweden, Denmark and the United Kingdom. The theoretical analysis indicates that taxing natural resource output or use typically represents a ‘second-best’ policy alternative, which can be used when, for instance, the monitoring of non-point source emissions is difficult or efficient property rights regimes cannot be established. The empirical analysis shows that the European aggregate taxes have assisted in reducing virgin resource use in spite of the relatively low own-price responses. However, generators of recycled materials typically have few incentives to enhance their waste sorting activities in the presence of a tax on virgin materials. Unless additional policies to increase the supply of recycled materials are implemented, supply will not increase much even in the presence of high demand. Finally, although second-best taxes are sometimes motivated by the desire to keep administration costs low, they could come at the cost of improper incentives and of limited policy legitimacy.     

Mediating an invisible policy problem: Nottingham’s rejection of congestion charging

ABSTRACT

This paper presents a qualitative case study of community participation in local air quality management in Nottingham (UK). We analyse Nottingham’s response to a “clean air zone” mandate: despite national government and local community support of this congestion charging policy, the City Council rejected the measure. We focus on the policy framing, with data from policy documents, interviews with government and non-government actors, and observation in local activities. We found that community groups build links with local government in two ways: (1) as a coalition against the national government and austerity measures, and (2) as “neutral”, non-expert communicators of air pollution as an “invisible” policy problem. We show how this invisibility plays a significant role in factors such as trust, risk, responsibility, and policy communication. This research has theoretical implications for the communication of air pollution and practical implications for cities looking to implement similar transport-oriented strategies.     

对燃油征税的区域能源环境影响研究:以中国为例

控制汽柴油消费对中国的能源安全和环境保护有着重要意义.燃油税和碳税是中国近期两种主要的已经或可能施加于燃油的税收政策.以自回归分布滞后模型为核心,本研究构建了一个燃油税和碳税的区域能源环境影响评估模型.利用模型估计了我国的燃油需求价格弹性,测算了燃油需求响应,计算了在相同CO2减排目标下,提高汽油消费税、提高柴油消费税、引入碳税三种政策情景下各省份预计产生的节能效应、减排效应和税收效益.研究结果显示,在相同的CO2减排目标下,第一,在不同情景下,各省份节能程度差异均有限,但节能数量均体现出区域匹配性,燃油消费越多的省份,节能数量一般越多,且提高汽油消费税的全国节能总量最大;第二,在引入碳税情景下,各省份CO2减排比例差异最小;第三,在全国层面,三种政策情景中空气污染物(PM2.5和NOx和SO2)减排数量均为提高汽油消费税>引入碳税>提高柴油消费税,但在提高柴油消费税情景下,有4/5的省份预计PM2.5排放减少程度超过14%.除此之外,提高汽油消费税的税收收益最大.     

我国区域空气污染治理效率及其影响机制——基于超效率SBM模型和门槛回归模型

随着人民对美好生活需求的日益增长,政府空气污染治理的效率问题日益得到重视。本文从地方政府空气污染治理效率及其影响因素的视角入手,以全国30个省份为研究对象,运用超效率SBM模型测算2003—2015年各省级区域的空气污染治理效率。在此基础上,运用门槛回归模型分析政府空气污染治理效率的影响机制。研究表明:①地区间空气污染治理效率差异性较为显著。中部、西部空气污染治理效率整体呈下降趋势。东部和东北地区空气污染治理效率则上升比较平稳。②政策规划、碳源、污染物排放和环境治理投入表现出双重门槛特征,其中碳源对空气污染治理效率影响显著,而以碳为首的能源消费结构则主要对中部和西部空气污染治理效率产生影响。落后地区政府应注重产业升级,财政上应对碳税等税目进行征收,产业上应鼓励企业创新,并对落后企业进行倒逼升级。     

Landfill diversion in a decentralized setting: A dynamic assessment of landfill taxes

We analyze the process of landfill diversion and its main determinants, by embedding the dynamics in a frame where economic, geographical and policy variables come into play. In addition to structural and economic drivers, we primarily investigate whether the Italian tax has been effective in supporting landfill diversion. Although the Italian landfill tax dates back to 1996, the oldest in the EU, its effectiveness in terms of landfill diversion has not been assessed yet. The complexity primarily derives from the decentralized regional implementation and the absence of a full coherent dataset covering all regions. We merge this new and original data on taxes to an integrated dataset which includes economic, waste and policy variables at regional level over the period 1999–2008. Panel regressions show that the effect of tax is significant, even when taking into account for its possible endogeneity. Regions that have increased such taxes have improved waste disposal performances over time. Landfill taxes are surely not the only instrument policy makers might introduce, but they seem to play a relevant role in the evolution of Italian waste disposal performances.     

Impacts on air pollution in urban areas

Environmental management involves controlling various forms of pollution to levels that do not pose a threat to the health of the people and the environment in general. This paper presents a framework to analyze sources of local air pollution in cities. Using an OLS model, an investigation is performed of the relationship among the concentrations of air pollutants [more precisely, concentrations of sulfur dioxide (SO₂), dust, nitric oxide (NO), nitrogen dioxide (NO₂), carbon oxide (CO) and ozone (O₃)], economic activities, and meteorology. Time series analysis leads to a model, that explains a high degree of the variance in the air pollution data. The model is applied to daily time series from three measurement stations in innsbruck, Austria. Estimation results of the model generally fit with the expected relations. Space heating influences SO₂, dust, and NO, while NO₂ levels are primarily affected by traffic. These results also indicate interdependent relations among the pollutants NO, NO₂, O₃, and CO; O₃ levels depend on temperature and sunshine.     

Adapting to Climate Change at the Local Level: The Spatial Planning Response

Abstract

Climate change is a major issue for all levels of government, global, national and local. Local authorities' responses to climate change have tended to concentrate on their role in reducing greenhouse gases. However, the scientific consensus is that we also need to adapt to unavoidable climate change. Spatial planning at a local level has a critical anticipatory role to play in promoting robust adaptation. This paper reviews the shift in local authorities' planning policies for climate change adaptation in the UK since 2000, and provides evidence of underlying attitudes amongst planning professionals to climate change. It shows that, while the issue of climate change is becoming recognized with respect to flood risk, the wider implications (for instance, for biodiversity and water resources) are not yet integrated into plans. The reasons for this lie in lack of political support and lack of engagement of the planning profession with climate change networks. But the paper also argues there are difficulties in acknowledging the need for adaptation at the local level, with the short-term horizons of local plans at odds with perceptions of the long-term implications of climate change.     

What shapes municipalities’ perceptions of fairness in windpower developments?

ABSTRACT

Siting controversies have become familiar in windpower development. Process and outcome fairness in the form of economic benefits to local communities and inclusion in decision-making processes are recognised as important elements in local acceptance of windpower installations. To these, we add the concept of “relative fairness” influencing perceptions of overall fairness. In this article, we examine why Norwegian municipalities agree to host windpower, and the role of process, outcome and relative fairness in this decision. Municipalities are central in providing welfare services, and in ensuring a viable local economy and local workplaces. Process fairness is important, as is evident when municipalities have little influence in the detailed planning of the plants. Also, outcome fairness, in the form of economic compensation – particularly through property tax – is decisive for positive attitudes towards windfarms, as municipalities can strengthen their role as welfare providers and boost local economic activities. Less emphasised are the effects on global climate and national climate goals. However, effects on local landscape and nature are also important for municipalities, as became clear when the national government proposed withdrawing the municipalities’ possibilities of levying property taxes. The municipalities argue that it is only fair to receive something in return for hosting windmills, and relative fairness is important to their argument for equal treatment regarding hydro- and wind-power electricity production in the form of a natural resource tax.     

ECONOMIC IMPLICATIONS OF PHOSPHORUS LOADING POLICIES FOR PASTURE LAND APPLICATIONS OF POULTRY LITTER1

ABSTRACT: Non-point source pollution created by agriculture is one of the major issues of intensive production. Recent studies indicate that the eutrophication from agricultural non-point source pollution, especially from phosphorus, is of growing concern. The objectives of this paper are to measure the economic opportunity costs of a proposed phosphorus management policy that targets soils with elevated phosphorus levels and examine the impacts of alternative policies such as Pigouvian taxes on the optimal use of litter. The study focuses on land applications of poultry litter in the Muddy Fork watershed of the Illinois River in Northwest Arkansas. The analysis indicates that restriction of litter applications on soils with elevated phosphorus levels will significantly reduce the net returns generated from forage production, resulting in an environmental policy with a high opportunity cost for producers. An analysis of alternative Pigouvian tax policies shows that a smaller tax per ton of litter applied can achieve the same litter control as that of a larger tax on a per acre basis.     

我国大气细颗粒物污染防治目标和控制措施研究

我国面临着严重的细颗粒物(PM2.5)污染问题,PM2.5对人体健康、能见度、气候变化、生态系统等均产生了不良影响。本文旨在提出我国PM2.5污染防治目标和控制措施,为从根本上改善空气质量提供科学依据。首先,本文提出了2020年和2030年我国PM2.5污染防治目标。其次,采用能源和污染排放技术模型,分情景预测了我国未来一次大气污染物排放量的变化趋势。基于情景预测结果和此前研究建立的一次污染物排放与PM2.5浓度间的非线性关系,确定了2020年—2030年与PM2.5浓度改善相适应的全国和重点区域大气污染物减排目标。最后,利用能源和污染排放技术模型,提出了实现大气污染物减排的技术措施和对策建议。研究表明,2030年全国二氧化硫、氮氧化物、一次PM2.5和挥发性有机物的排放量应分别比2012年至少削减51%、64%、53%和36%,氨排放量也要略有下降。对于污染严重的重点区域,必须采取更严格的控制力度。要实现上述减排,应加快能源结构调整,推进煤炭清洁高效集中可持续利用,建立"车-油-路"一体的移动源控制体系,并强化多源多污染物的末端控制。     

Spatially identifying vulnerable communities to climate change impact in South Australia

The impending form and extent of climate change and its direct impacts present disproportionate challenges for the most socially and economically disadvantaged groups within populations. Evaluating the vulnerability of disadvantaged groups in the context of climate change has presented tremendous theoretical, methodological and policy challenges especially where vulnerability assessment research is focused at the local community level. This study addresses the challenges by developing an interdisciplinary methodology, based on expert knowledge, and uses the state of South Australia as a case study. It focuses on key indicators that measure the exposure of local communities to climate change and socio-economic vulnerabilities of local populations. A main contribution in this study is the novel incorporation of physical, environmental and socio-demographic data sets and extensive use of spatial modelling and estimation methods to spatially define climate change and social vulnerability “hot spots”. This paper assesses vulnerability under moderate and high Intergovernmental Panel on Climate Change CO₂ emission scenarios in order to generate an assessment model to be used before planning is done. The result is the creation of a practical tool through which decision-makers can better understand how the complexity of one's local spatial context influences the unique exposure, which different vulnerable communities have, to the impacts of climate change. This paper presents a useful tool that can be used in the initial assessment phase by planners and policy-makers to better assist those who are limited in their ability to adapt to climate change.

关于改进“绿色化税制”测量方法的探讨

“绿色化税制”通常使用两项指标来进行测量：环境相关税收入占GDP的百分比和环境相关税收入占国家税收总收入的百分比。但是,这两个指标也存在着一个很大的缺点：当污染税增加时,税收收入也增加。因此,本文通过探讨测量绿色税制的指标,建立一个简单的分析框架,通过有效性、数据的可用性、全时段的比较、国际相似性、易聚合性、免税和减税、有限的复杂性七个指标来进行评价。最后,基于四种类型的指标的优缺点来做总结,对绿色税制的优化给出建议。     

Analysis of energy security and sustainability in future low carbon scenarios for Brazil

This study estimated a series of indicators to assess the energy security of supply and global and local environmental impacts under different mitigation scenarios through 2050 in Brazil, designed with the integrated optimization energy system model MESSAGE‐BRAZIL. The assessment of interactions between environmental impacts and energy security dimensions was complemented through the application of life cycle assessment (LCA) methodology. Overall results imply energy security establishes more synergies than trade‐offs in increasingly stringent mitigation scenarios, especially patent within the sustainability dimension, which increases energy security and provides additional benefits regarding climate change mitigation and air pollution emissions. It is still necessary to extend analysis to other energy sectors in addition to the power supply sector and to promote a better understanding of repercussions of energy scenario expansion in energy security.
