One global deal from Paris 2015: Convergence and contestations on the future climate mitigation agenda

This article analyses the 2015 Paris Agreement of the UN Framework Convention on Climate Change, with a focus on mitigation. The history of climate negotiations and the mitigation agenda shows the divide between developed and developing countries, with the latter insisting that the former, having caused the problem, need to do more to reduce carbon emissions to address climate change. However, as some emerging economies had continued to emit more carbon, there were calls to treat these as developed countries, requiring increased mitigation measures. The article examines the record of these emerging economies, and establishes that there was some convergence in Paris, a positive element that resulted in a single global climate treaty. However, the Paris negotiations also witnessed contestations, with the final agreement insufficient to keep global warming within advised limits, and in any case only partly legally binding, leaving its implementation success to good will.     

The problem of past emissions and intergenerational debts

The problem of past emissions – how to share fairly the costs of climate-changing emissions caused by polluters who are no longer in existence – presents an increasingly pressing challenge to scholars and policy-makers. Since standard contribution-based principles are inapplicable when it comes to past emissions, theorists have instead proposed various non-contribution-based historical principles. This paper develops such a principle – the Inherited Debt Principle – which seeks to account for the intuition that historical injustice matters to current duties in a way that does not appeal to the counterfactual benefits derived from that injustice. This principle, it is argued, offers a surprisingly plausible solution to the problem of past emissions.     

Meeting Human Development Goals with Low Emissions : An Alternative to Emissions Caps for post-Kyoto from a Developing Country Perspective

This paper proposes a post-Kyoto scenario on commitment issues from a developing country perspective in which commitments by developing countries will be linked to human development goals as the first priority and ultimate goal, and then translated to carbon goals. Three different types of commitments are discussed with particular reference to developing country participation, including voluntary, conditional and obligatory. For low-carbon development, there should be no luxurious emissions but human development needs should not be compromised. A progressive and internationally coordinated taxation on carbon is suggested as an incentive mechanism under this approach. However, there are a few issues requiring further examination, including specification of basic needs and determination of progressive tax rates.     

An Economic Analysis of Flexible Permit Trading in the Kyoto Protocol

This paper evaluates the relative gains from augmenting or restricting several of the flexibility mechanisms of the Kyoto Protocol. A nonlinear programming model of international emissions trading is used to assess the net benefits of extending trading across time periods and across countries (Joint Implementation), and including the developing world (Clean Development Mechanism). The effect of limiting permit purchases (supplementarity) is also evaluated. The analysis is intended to help guide further climate negotiations by identifying flexibility mechanisms that contribute the most to enhancing the gains from greenhouse gas mitigation and identifying restrictions that detract the most from these gains.     

Implementing EU emissions trading: success or failure?

This article assesses and explains the implementation of the EU emissions trading scheme (EU ETS). It argues that implementation in terms of ambitiousness has been only moderately successful so far, but significant differences between the Member States are also observed. Similarities and differences are then explained within a multi-level governance approach emphasizing the need to search for explanations at national, EU, and global levels. The EU ETS case shows that the multi-level governance approach can be as relevant for understanding implementation as for explaining policy-making. In addition to factors located at the national level, the decentralized nature of the EU scheme itself is important for understanding how the system works in practice. At the global level, the link to the Clean Development Mechanism under the Kyoto Protocol is particularly important for determining how well the EU ETS will perform in the future.     

Improving Cost-effectiveness and Facilitating Participation of Developing Countries in International Emissions Trading

This paper discusses ways in which the next climate agreement – a renegotiated Kyoto Protocol or a second-period agreement – can be made more cost-effective. The discussion focuses on the design of international emissions trading to facilitate early participation by developing countries. Four aspects are highlighted: the design of compensation rules, the need to regulate the use of the CDM, the effect of allowing borrowing and the implications of a Commitment Period Reserve.     

伪聋的瞬态诱发性耳声发射的研究

目的　探讨识别伪聋的客观方法。方法 运用瞬态诱发性耳声发射技术(TEOAE),对60个案例分3组,即伪聋组、正常对照组及感音神经性聋组进行瞬态诱发性耳声发射测试。结果 (1)正常对照组的检出率为96.67％,感音神经性聋组的检出率为20.00％,两组比较有显著性差异(P<0.05);(2)伪聋组的检出率为100％,与正常对照组比较无显著性差异(P>0.05)。结论 TEOAE检查,可发现感音神经性聋患者的听功能障碍。TEOAE技术对伪聋有识别作用,并当听力下降>40 dBHL时,检出率为零。

追溯与寻明:国际法视角下的碳排放权单位研究

自以《京都议定书》为基础的市场化机制建立以来,经过近20年的发展,全球碳金融市场呈现蓬勃发展的态势,交易量大幅提升,成交金额不断攀升,市场化机制在夯实中不断完善和发展。同时,争端与纠纷日益增加,国际多边环境公约调整下的碳排放权机制部分地在WTO体制下进行规制,成为众多学者的憧憬。碳排放权单位体现的既不是GATT框架下的"产品",也不是GATS框架下的"服务",而是在经济上反映出特殊的金融衍生产品的属性。然而,碳排放权单位交易商提供服务的行为契合GATS金融服务要求,因此交易商可依据GATS享受跨国服务领域中的最惠国待遇,并可将与WTO规则相关的争端诉诸WTO争端解决机制,实现环境争端解决的规范化、法制化。
