The European Union (EU) is implementing a Carbon Border Adjustment Mechanism (CBAM) at its borders, which will require exporters of basic materials to surrender emission permits when exporting to the EU market. Since it makes foreign producers compete under a carbon price, the EU CBAM may...

Slowing global warming requires countries to reduce carbon emissions, which imposes costs on their economies. To be effective, most countries must agree collectively to participate (e.g., the Paris Agreement, COP26). However, every country has an incentive not to comply and still reap the...

We explore a global carbon pricing framework to inform the potential coordination of carbon pricing and equivalent policies. The framework has three main features aligning with the current multilateral system for climate action. First, the carbon price is determined by a global average carbon...

The paper considers a situation where two countries - the North and the South - use a non-traded polluting input to produce the goods for final consumption. The North is more efficient in both, production and abatement processes. The study compares the effects of the transfer of abatement...

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...

The Nationally Determined Contributions (NDCs) under the Paris Agreement fall short of the abatement needed to reach the 2°C target. Emissions trading could be a "costless" means to reduce the ambition gap if countries used their gains from trade for additional abatement. However, this requires...

Copenhagen Consensus Center organized an initiative, in which an Expert Panel of outstanding economists convened in Washington DC in September 2009 to compile a prioritized list of specific solutions in the fight against Climate Change. The basis for the discussions and the ranking were...

This paper provides an overview of current government schemes promoting corporate reporting of greenhouse gas (GHG) emissions and analyses their main building blocks. It describes the drivers and challenges for governments, companies and investors in dealing with GHG reporting and includes 4...
