The transport sector is the only sector where carbon emissions continue to grow. This has led policy makers to propose ambitious policies to reduce emissions in the car sector, in particular fuel efficiency standards, portfolio mandates for Electric Vehicles and purchase taxes or subsidies. A...

The efficiency case for raising fuel tax minima under the EU Energy Tax Directive (ETD) appears nuanced. Some fuels may be undertaxed (e.g., road diesel, natural gas), while others may be adequately taxed already (e.g., gasoline). Reform proposals would increase some minima, including for road...

Because of a link between the EU ETS and the Kyoto Flexible Mechanisms, the emission certificates traded on these markets are in principle interchangeable assets; despite of this, a persistent price difference exists. We explain this price spread using a theoretical model that combines three...

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...

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...

For any emission trading system (ETS) with quantity-based endogenous supply of allowances, there exists a negative demand shock, e.g. induced by abatement policy, that increases aggregate supply and thus cumulative emissions. We prove this green paradox for a general model and then apply it to...

With the new rules of the EU ETS, involving cancellation of allowances, cumulative emissions are no longer fixed but depending on the market outcome. Perino (2018) showed that additional abatement effort can reduce cumulative emissions if it occurs within a few years. This article shows that...

This paper discusses lessons that other regions could learn from European Union’s effort to implement carbon pricing through EU Emission Trading System (EU ETS). Our lessons are, first of all, that a cap-and-trade system like EU ETS is very helpful in guaranteeing a credible and binding...
