Countries have pledged to stabilize global warming at a 1.5 to 2°C increase. Either target requires reaching net zero emissions before the end of the century, which implies a major transformation of the economic system. This paper reviews the literature on how policymakers can design climate...

The UK has pledged to cut greenhouse gases 68 percent below 1990 levels by 2030, to be emissions neutral by 2050, and to phase out internal combustion engine vehicles by 2030. Much progress has been made, but fully achieving these ambitious objectives with the current policy framework will be...

In 2018, an agreement between the key EU institutions - the Commission, the European Parliament, and the European Council - was reached after a long-lasting discourse over the 2030 EU climate and energy policy package. This paper offers a comprehensive assessment of the EU package, with its...

In June 2018, an agreement between key EU institutions - the Commission, the European Parliament, and the European Council - was reached after a long-lasting discourse over the 2030 EU climate and energy policy package. This paper offers a comprehensive assessment of the EU package, with its...

Concerns about fairness among countries remain significant obstacles to a stronger global climate treaty. This paper addresses the distributional implications of two mechanisms to strengthen the Paris Agreement: the incorporation of national carbon pricing, and the tightening of nationally...

We study optimal climate policy in a global economy where regions differ in wealth and climate vulnerability. Carbon emissions from production lead to output losses, and there is a technology for emissions absorption. We provide an aggregation result: the model with heterogeneity can be cast...

We find that both economic theory and empirical results show that carbon border adjustment mechanisms (CBAMs) will be ineffective at meeting global carbon emissions goals. The consensus of 12 computable general equilibrium (CGE) model estimates is that CBAMs can be expected to reduce (but not...

The present paper analyzes the impact of a climate coalition's border carbon adjustment on emissions from commodity production, welfare and the coalition size. The coalition implements border carbon adjustment to reduce carbon leakage and to improve its terms of trade, while the fringe abstains...

Transportation is one of the main contributors to greenhouse gas emissions. Climate regulations on transportation are often a mix of sector-specific regulations and economy-wide measures (such as emission pricing). In this paper we analyse the effects on economic welfare, abatement costs and...

This paper explains how, in the context of incomplete coordination among all countries, unilateral policies that might at first sight seem pro-green could actually turn out to harm the global environment. The free-riding motives and the difficulty of reaching an effective international...
