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...

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...

Quoting a joint analysis undertaken by the OECD and the IEA, G-20 leaders committed in September 2009 to “rationalize and phase out over the medium term inefficient fossil-fuel subsidies that encourage wasteful consumption.” This report draws on previous OECD work to assess the impact on...

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...

Competitiveness and carbon leakage issues have been some of the main concerns in the implementation and discussions of climate policies. These concerns are particularly important in the presence of multiple carbon markets since differences in climate change policy approaches may have impacts on...

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 global screening study makes a first estimate of the exposure of the world's large port cities to coastal flooding due to storm surge and damage due to high winds. This assessment also investigates how climate change is likely to impact each port city's exposure to coastal flooding by the...
