The Paris Agreement invites signatory countries to formulate and communicate long-term low greenhouse gas emission development strategies (LT-LEDS). This report compares the experience of three developed countries that have communicated LT-LEDS within the framework of the United Nations...

A two-tier climate club exploits the comparative advantage of large countries to mete out punishments through trade, while taking their capacity to resist punishment as a constraint. Countries outside the coalition price carbon at a fixed fraction of the average carbon price adopted within the...

This paper presents the potential benefits and challenges of enhanced international co-ordination on carbon pricing and outlines the different types and levels of co-ordination that are available for national and sub-national governments. These levels include, inter alia, facilitating new...

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...

In this paper we try to quantify/measure the main factors that influence the equilibrium outcome and pursued strategies in a simplistic model for the use of fossil versus green energy over time. The model is derived using the standard Solow macro-economic growth model in a two-country setting...

Denmark has a highly ambitious goal of reducing greenhouse gas emissions 70 percent below 1990 levels by 2030. While there is general agreement that carbon pricing should be the centerpiece of Denmark’s mitigation strategy, pricing needs to be effective, address equity and leakage concerns,...

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 light of the urgency for policy action to address climate change, this report provides the first detailed global catalogue of targets and policies for mitigating greenhouse gas emissions in the Agriculture, Forestry and Other Land Use (AFOLU) sector. It covers 20 countries which collectively...

This policy brief argues in favor of a new urban model that harnesses the power that cities have to curb global warming. Such a model tackles fundamental management challenges in the energy, building and transport sectors to promote the growth of diverse and compact cities. Such a model is...
