This paper describes a model, implemented in an Excel spreadsheet, for evaluating a wide range of fiscal and regulatory instruments policymakers might consider for implementing their Paris mitigation pledges. Policies are evaluated against a range of metrics, including impacts on carbon dioxide...

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...

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 efficiency effects of carbon pricing depend on how it impacts distortions in fossil fuel markets, most notably from local air pollution externalities. By offsetting these distortions, carbon pricing may generate significant net economic benefits, so it is in countries own interests to...

In the wake of the December 1997 Kyoto Protocol, which if implemented would oblige the United States and other industrialized countries to reduce greenhouse gases (GHGs) by 2008-2012, a number of proposals have been offered to increase the incentives for emissions reductions over the nearer...

This paper calculates, for the top twenty emitting countries, how much pricing of carbon dioxide (CO2) emissions is in their own national interests due to domestic co-benefits. On average, nationally efficient prices are substantial, $ 57.5 per ton of CO2 (for year 2010), reflecting primarily...

This paper discusses techniques for measuring the incidence of carbon taxes across different household income groups and provides some cross-country estimates of these effects for selected advanced countries. The general message of this paper is that distributional concerns should not...

Energy models suggest that the cost of reducing carbon emissions from the transportation sector is high relative to other sectors, such as electricity generation. However, this paper shows that taxes to reduce passenger vehicle emissions produce large net benefits, rather than costs, when...

This paper examines alternative ways that the value of CO2 emissions allowances created under cap-and-trade policy could be returned to households. One approach (based on principles of economic efficiency) is effectively a "tax shift" that would use revenues from an auction of CO2 emissions...

This paper employs analytical and numerical general equilibrium models to assess the efficiency impacts of two policies to reduce U.S. carbon emissions - a carbon tax and a carbon quota ? taking into account the interactions between these policies and pre-existing tax distortions in factor...
