This paper uses patent data to assess policy factors (domestic and international) for patenting activity in automotive emission control technologies. Particular attention is paid to the role of different policy types and fuel prices on both post-combustion and integrated abatement technologies....

The California Global Warming Solutions Act of 2006 (AB 32) commits California to reduce its greenhouse gas (GHG) emissions to 1990 levels by 2020. The transportation sector is the top GHG emitter in California, contributing roughly 40 percent of all California emissions. Poor fuel efficiency...

In 2006, the Stern Review predicted dire consequences for the world's economy unless atmospheric greenhouse gases, responsible for climate change, are prevented from reaching dangerous levels. The Review identified transport as one of the fastest growing sources of global emissions and the motor...

This paper considers whether the California Air Resources Board, in implementing regulations to achieve the greenhouse gas reduction goals of the AB32 legislation, should include motor vehicle fuels as part of a cap-and-trade program. Its conclusion is that it is of importance to do so. While...

We quantify the effects of the Swedish GCR, a program to reduce oil dependence and greenhouse gas emissions in the automobile industry. We ?nd the GCR to increase the market shares of `green cars' and its cost to be $109/tonCO2 saved, thus 5 times the price of an emission permit. Since the main...

I study the impact of subsidies for Plug-in hybrid vehicles (PHEV) on carbon emissions. I show that subsidizing innovations without considering consumer behavior can harm the environment. I provide descriptive evidence on charging instances of PHEV and combine it with a structural model of...
