This paper provides a first analysis of optimal offset policies by a "policy bloc" of fossil fuel importers implementing a climate policy, facing a (non-policy) fringe of other importers, and a bloc of fuel exporters. The policy bloc uses either a carbon tax or a cap-and-trade scheme, jointly...

This paper considers the impacts of "finance blending" whereby climate finance is added to international carbon markets for offset trading. The paper first discusses climate finance and the carbon market as free-standing finance solutions by high-income countries to increase mitigation in...

This study uses a computable general equilibrium model to analyze various policy scenarios for a carbon tax on greenhouse gas emissions from petroleum fuels and kerosene in Ethiopia. The carbon tax starts at $5 per ton of carbon dioxide in 2018 and rises to $30 per ton in 2030. Different...

The 2015 Paris Climate Agreement was the first instance of countries adhering to take a collective action against global warming. More than 190 countries came forward and submitted their contributions in the form of Intended Nationally Determined Contributions, reflective of their ability and...

The international aviation and maritime sectors today enjoy relatively favorable tax treatment, as their fuels are not taxed and the sectors are not subject to any value-added tax or turnover tax. Nor are these fuel uses subject to any global measures to reduce their associated CO2 emissions,...

The fact that developing countries do not have carbon emission caps under the Kyoto Protocol has led to the current interest in high-income countries in border taxes on the "virtual" carbon content of imports. The authors use Global Trade Analysis Project data and input-output analysis to...

This paper uses simple analytical models to study high-income donor countries' willingness to pay to supply mitigation finance to low-income countries; how this depends on modality for finance supply; and how it changes as the global greenhouse gas mitigation agenda moves forward. The paper...
