Evaluating Experience with Renewables Portfolio Standards in the United States

Increased use of renewable energy is one of several promising methods for reducing emissions of local, regional, and global air pollutants, including greenhouse gas emissions associated with fossil-fuel based electricity production. Among the available options for encouraging renewable electricity generation, the renewables portfolio standard (RPS) has become especially popular in recent years. The RPS is a newly established policy mechanism, however, and experience with its use has not been widely documented and evaluated. This paper describes and evaluates the design, impacts, and early experience of 13 U.S. state RPS policies. These 13 policies share a common goal of encouraging renewable energy supply, but each specific RPS is designed differently. Our evaluation shows both successes and failures with this policy mechanism; some state RPS policies are positively impacting renewable energy development, while others have been poorly designed and will do little to advance renewable energy markets.We emphasize the importance of policy design details, and specifically highlight critical design pitfalls that have been commonly experienced. Though experience with the RPS is still limited, we have now gained some knowledge of the conditions and design features necessary to make an RPS policy work. An important objective of this article is therefore to identify and describe broad policy design principles and specific best practice design elements that might be used to guide the design of future renewables portfolio standards.

The minerals sector, sectoral analysis, and economic development

Sectoral analysis, a new branch of political science, alleges that mineral extraction creates a socio-political climate that promotes inflexible statism, which in turn leads to substandard development performance. The theory, that mineral economies underperform bureaucratically and economically, is said not only to hold in a post-dictive sense for the mature mineral economies, such as Zambia, but also in a predictive sense for the newer mineral economies, such as Ecuador. This essay reviews and assesses this hypothesis in the light of the empirical evidence comparing mineral production, state capacity, and economic performance. It finds that the sectoralist view is supportable only in selected cases, and is not a general result.

The market-incentive recycling system for waste packaging containers in Taiwan

This paper presents a new market-incentive (MI) system to recycle waste-packaging containers in Taiwan. Since most used packaging containers have no or insufficient market value, the government imposes a combined product charge and subsidy policy to provide enough economic incentive for recycling various kinds of packaging containers, such as iron, aluminum, paper, glass and plastic. Empirical results show that the new MI approach has stimulated and established the recycling market for waste-packaging containers. The new recycling system has provided 18,356 employment opportunities and generated NT$ 6.97 billion in real-production value and NT$ 3.18 billion in real GDP during the 1998 survey year. Cost-effectiveness analysis constitutes the theoretical foundation of the new scheme, whereas data used to compute empirical product charge are from two sources: marketing surveys of internal conventional costs of solid-waste collection, disposal and recycling in Taiwan, and benefit transfer of external environmental costs in the United States. The new recycling policy designed by the authors provides a reasonable solution for solid-waste management in a country with limited land resources such as Taiwan.

The Monitoring,Evaluation, Reporting and Verification of Climate Change Projects

Because of concerns with the growing threat of global climate change from increasing emissions of greenhouse gases, the United States and other countries are implementing, by themselves or in cooperation with one or more other nations, climate change projects. These projects will reduce greenhouse gas (GHG) emissions or sequester carbon, and will also result in non-GHG benefits (i.e., environmental, economic, and social benefits). Monitoring, evaluating, reporting, and verifying (MERV) guidelines are needed for these projects to accurately determine their net GHG, and other, benefits. Implementation of MERV guidelines is also intended to: (1) increase the reliability of data for estimating GHG benefits; (2) provide real-time data so that mid-course corrections can be made; (3) introduce consistency and transparency across project types and reporters; and (4) enhance the credibility of the projects with stakeholders. In this paper, we review the issues involved in MERV activities. We identify several topics that future protocols and guidelines need to address, such as: (1) establishing a credible baseline; (2) accounting for impacts outside project boundaries through leakage; (3) net GHG reductions and other benefits; (4) precision of measurement; (5) MERV frequency and the persistence (sustainability) of savings, emissions reduction, and carbon sequestration; (6) reporting by multiple project participants; (7) verification of GHG reduction credits; (8) uncertainty and risk; (9) institutional capacity in conducting MERV; and (10) the cost of MERV.

提高环境政策法律效益的探讨

首先探讨环境行为的相关性强、连带影响大、副作用多的特性 ,揭示和比较行为限制与区域限制的区别和联系 ;然后讨论环境政策易产生间接影响、极易产生经济效应和社会效应的特性和环境政策实施会造成暂时性经济损失 ,造成部分人暂时生活困难的特性。在此基础上 ,提出保护策略应从单纯“禁、堵”策略改为“禁、堵、疏、导”策略 ,强调应加强环境政策社会学分析和环境政策经济分析 ,加强环境政策评估 ,以提高环境保护效益     

日本森林管理的最新发展——以日本神奈川县林业政策过程为例

为了追求更好的森林管理效果,对相关森林政策的实施,不是仅仅停留在传统的狭义的行政管理部门上,同时还要涉及到经营者、市民以及当地居民等利益相关者,使他们都要以相互协调的方式参与到森林管理当中来.它是建立在一定的森林价值现基础上,基于科学原理并突破以往的技术层面而对森林进行的一系列更加合理的管理措施体系.本文以日本神奈川县的林业政策形成过程为例对森林治理问题进行了讨论.
