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 examines the cost of a range of national, regional and global mitigation policies and the corresponding incentives for countries to participate in ambitious international mitigation actions. The paper illustrates the scope for available instruments to strengthen these incentives and...

Concern that unilateral greenhouse gas emission reductions could foster carbon leakage and undermine the international competitiveness of domestic industry has led to growing calls for carbon-based border-tax adjustments (BTAs). This paper uses a global general equilibrium model to assess the...

This report focuses on the effects of climate change impacts on economic growth. Simulations with the OECD’s dynamic global general equilibrium model ENV-Linkages assess the consequences of a selected number of climate change impacts in the various world regions at the macroeconomic and...

This document describes economic baseline projections to 2050 for several world regions. It describes how socio-economic drivers are used to create a consistent projection of economic activity for the coming decades, applying the general framework of “conditional convergence”. This economic...

This document provides a detailed technical description of the ENV-Linkages model. The OECD ENV-Linkages Computable General Equilibrium (CGE) model is an economic model that describes how economic activities are inter-linked across several macroeconomic sectors and regions. It links economic...

Determining comparability of effort between mitigation actions and targets proposed by different countries is an ongoing issue for international climate negotiations. A number of indicators have been proposed to reflect comparability of effort and differences in national circumstances; key...

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...
