Carbon taxes are advocated as efficient fiscal and environmental policies, but they have proven difficult to implement. One reason is that carbon taxes can aggravate poverty by increasing prices of basic goods and services such as food, heating, and commuting. Meanwhile, cash transfer programs...

One question surrounding the 2009 U.S. “Cash for Clunkers” program is whether it induced consumers to purchase greener vehicles than they would otherwise have purchased. This paper views the program as a natural experiment, which offered higher rebates to consumers buying more fuel-efficient...

We introduce a new microsimulation model built on household transport data to study the distributional effects of carbon-based fuel taxation of private road transport in Germany. Our data includes annual mileage at the car-level, the distinction between fuel types, as well as car-specific fuel...

This study analyses the economic effects of the EU's ‘Fit for 55’ climate mitigation policies using the OECD ENV-Linkage model, a dynamic, global Computable General Equilibrium model. The model projects macroeconomic, sectoral, energy and emission trends for the EU, and for the five largest...

The Kyoto Protocol's success or failure should be evaluated against the unobserved counterfactual of no treatment. This requires instrumental variables. We find that countries' membership in the International Criminal Court (ICC) predicts Kyoto ratification in a panel model. Both multilateral...

We evaluate German purchase subsidies for battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) using data on new vehicle registrations in Germany during 2015-2022. We account for confounding time trends and interacting EU-level CO2 standards using neighboring countries...

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...

This paper analyses the effects of government policies on flows of private finance for investment in renewable energy (inducement effect). It also examines whether direct provision of public finance for a project increases the volume of private finance raised (“crowding in” effect). A unique...
