Financing for adaptation is a core element in the ongoing international negotiations on climate change. This has motivated a number of recent global estimates of adaptation costs. While important from an agenda setting perspective, many of these estimates nevertheless have a number of...

Tackling the problem of global climate change requires a high level of international cooperation. Many countries have pledged targets or actions to reduce greenhouse gas emissions in the Appendices to the Copenhagen Accord. This analysis examines the costs and effectiveness of these pledges,...

In recent years, businesses, local governments and individuals have set goals for reducing their emissions of greenhouse gases. In addition to directly reducing their own emissions, many of these entities have purchased carbon offsets to help achieve their mitigation goals. Yet establishing...

L’allocation de permis d’émission, notamment celle s’inscrivant dans le cadre du Protocole de Kyoto pour six gaz à effet de serre (GES), a suscité et suscitent encore de vives discussions politiques sur la question de savoir qui (quel pays ou quelle région) devrait supporter un effort...

The present report seeks to inform critical questions with regard to policy mixes of investments in adaptation and mitigation, and how they might vary over time. This is facilitated here by examining adaptation within global Integrated Assessment Modelling frameworks. None of the existing...

Considering the costs and risks of inaction, ambitious action to reduce greenhouse gas emissions is economically rational. However, success in abating world emissions will ultimately require a least-cost set of policy instruments that is applied as widely as possible across all emission sources...

This paper reviews alternative (national and international) climate change mitigation policy instruments and interactions across them. Carbon taxes, cap-and-trade schemes, standards and technology-support policies (R&D and clean technology deployment) in particular are assessed according to...

This document forms a record of a workshop held on 16 January 2006, aimed at examining the mechanisms underlying cross-country convergence of per capita GDP, to what extent they operate in practice, and the implications for policies, including those requiring plausible long-term projections of...

Climate change is expected to have significant implications for the world economy and, more broadly, for many areas of human activity. The purpose of this review is twofold. First, it is to summarise current estimates of the impacts of climate change and to explain how these estimates are built...

There are local air pollution benefits from pursuing greenhouse gases emissions mitigation policies, which lower the net costs of emission reductions and thereby may strengthen the incentives to participate in a global climate change mitigation agreement. The main purpose of this paper is to...
