Denmark has been a frontrunner in policies that reduce greenhouse gas emissions and now plans to cut emissions by 70% by 2030 from 1990 levels and to achieve carbon neutrality by 2050. Such ambition induces halving emissions from 2019 levels and making the same emission abatement effort in ten...

Les autorités ont défini un programme très ambitieux en matière de politique de l’environnement, dont les grands axes sont, outre la réduction des émissions de gaz à effet de serre (GES), la lutte contre la pollution atmosphérique locale et la pollution de l’eau, la gestion des...

This paper develops and applies a simple “conditional growth” framework to make long-term GDP projections for the world economy, taking as a starting point recent empirical evidence about the importance of total factor productivity and human capital in explaining current cross-country...

Korea’s greenhouse gas emissions almost doubled between 1990 and 2005, the highest growth rate in the OECD area. Korea recently set a target of reducing emissions by 30% by 2020 relative to a “business as usual” baseline, implying a 4% cut from the 2005 level. Achieving this objective in a...

This paper uses the WITCH model, a computable general equilibrium model with endogenous technological change, to explore the impact of various climate policies on energy technology choices and the costs of stabilising greenhouse gas concentrations. Current and future expected carbon prices...

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...

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...

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...

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...

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...
