Terminating links between emission trading programs

Links between emission trading programs are not immutable, as highlighted by New Jersey׳s exit from the Regional Greenhouse Gas Initiative in 2011. This raises the question of what to do with existing permits that are banked for future use—choices that have consequences for market behavior in advance of, or upon speculation about, delinking. We consider two delinking policies. One differentiates banked permits by origin, the other treats banked permits the same. We describe the price behavior and relative cost-effectiveness of each policy. Treating permits differently generally leads to higher costs, and may lead to price divergence, even with only speculation about delinking.     

我国探矿权资产化、证券化的模式及设想

探矿权资产化、证券化是我国改革探矿业投融资体制，解决探矿业资金瓶颈问题的关键。本文从制度建设、机构投资者的发展状况等方面分析了我国初步推行探矿权资产化、证券化的有利条件．指出了探矿权资产化、证券化的三种模式。并以基金模式和股权模式为例提出了实施探矿权资产化、证券化的步骤设想。     

浅论国家环境权

随着全球环境的日益恶化和公民环保意识的不断增强，环境权理论迅速发展。国家环境权作为一项重要的环境权。在环境法理论逐步变革和权利内涵不断演进的趋势下，已成为法学界研究探讨的重要课题。通过分析国家环境权的国内、国际法律基础。论证了国家环境权的确立。利用类比的方法。阐述了国家环境权与其他宪法权利的不同之处。从权利义务的对等统一和国内国际两个层面。重新归纳了国家环境权的内容。初步构建了国家环境权的基本理论框架。     

区域排污权交易模型研究

本文在分析了排污权交易研究进展的基础上，指出区域污染权交易比传统的排污权交易意义更大，并提出排污权交易地区交叉补贴的设想：将发达地区的排污权交易所得向欠发达地区转移，以解决欠发达地区产业结构调整乏力以及对发达地区的二次污染和发达地区环境容量资源短缺问题。在不考虑交易成本的假设下，通过建立不同地区排污权交易模型以确定排污权交易总量及其交易价格以及交易所获净增纯收益等。太湖流域由于经济最为发达，环境问题十分突出，是目前我国最适宜率先进行区域排污权交易试点的地区。通过假定太湖流域无锡和常州两市进行排污权交易，并利用两市1991—2000年的环境统计资料等相关资料进行了验证。计算结果表明区域排污权交易不仅具有明显的经济和环境效益，而且也是协调环境区域矛盾的重要手段。因此，不同地区间进行排污权交易在我国具有重要意义，在太湖流域等经济发达地区收效尤其明显。     

广州市实施二氧化硫排污权交易研究

在排污权交易的理论基础上,借鉴美国二氧化硫排放权交易的政策和方法,设计了一套广州市实施二氧化硫排污权交易的框架,旨在为广州市控制削减二氧化硫排放提供一种基于市场的环境管理手段.     

论环境参与权

环境参与权是公民享有的一项重要环境权利。它包括参与环境立法权、环境行政听证权、参与环境决策权和环境监督权，确立环境参与权具有重要意义，但我国现行立法很不完备，需要进一步完善。     

刍议排污权价格的合理界定

排污权交易在中国的试点过程中,显现了强大的生命力,然而,由于对排污权交易基础理论理解的偏差,导致了实践层面上的缺陷,如排污权初始分配是否应该有偿的问题;排污权商品再分配价格应不应该包括正的外部效应价值问题;在排污权交易制度改革与中国其他制度的改革(现行税制改革、绿色GDP的推行)进行中出现的不协调的问题.     

Optimising the environmental benefits of emission reductions from UK coal- and oil-fired power stations: a critical loads approach

This paper describes a method for determining reductions of SO₂ emissions from coal- and oil-fired power stations, oil refineries and large industrial units in the UK taking into account their pollution potential. The method is based on the use of two gridded data sets: critical loads, which represent the sensitivity of the environment to acid deposition and modelled estimates of total (wet + dry) sulphur deposition for 646 point sources within the UK. An iterative method is used to identify and subsequently reduce emissions from point sources that contribute most to areas of critical loads exceedance. This paper demonstrates how the method may be used to determine an optimal allocation of emissions across the UK which yields the maximum amount of environmental protection per unit of emission.The paper then goes on to consider the changes that will have to take place within the UK power generation industry in order to meet the revised EC Large Combustion Plant Directive which comes into force on 1 January 2008. Particular emphasis is placed upon proposed emissions trading schemes and the environmental implications of allowing trading between stations with high and low pollution potentials. The paper concludes by suggesting that the emissions trading process should take into account the pollution potential of each source, irrespective of whether the proposed emission is within the plant's agreed emission limit. An approach based entirely on minimizing environmental damage rather than one which takes cost into account, as in current integrated assessment modelling, could provide an interesting approach across the rest of Europe.
