MIT study finds fuel economy standards are 6-14 times less cost effective than fuel tax for reducing gasoline use

Green Car Congress

In a study published in the journal Energy Economics , MIT researchers have found that a fuel economy standard is at least six to fourteen times less cost effective than a fuel tax when targeting an identical reduction in cumulative gasoline use (20% by 2050).

Study finds behavior-influencing policies remain critical for mass market success of low-carbon vehicles

Green Car Congress

More than 90% of such vehicles are powered by internal combustion engines burning oil-derived fuels. Encouraging the use of low-carbon alternatives is an essential part of meeting climate change targets as well as improving local air quality and health. —McCollum et al. Note the different scaling used in the graphs.

Study concludes significant additional transport policy interventions will be required for Europe to meet its GHG reduction goal

Green Car Congress

EU climate policy aims to limit the global mean temperature increase from anthropogenic climate change to below 2 °C. They estimated the number of new vehicles required and the adoption of new technologies and fuels based on their availability and cost effectiveness under projected scenario variables such as fuel price.

The policy package includes a new fuel economy readiness index, which measures the extent to which countries have implemented steps that will fully exploit the potential of existing fuel economy technologies and maximise their use in vehicles. Fiscal measures can have a strong influence on vehicle-purchasing behavior.

California ARB mods to ZEV regulations for IVMs would result in ~1.9% drop in total ZEV/TZEV units 2018-2025; no impact on air quality requirements

Green Car Congress

In addition, although many experts say that the solution to our energy and climate problems is sending the correct price signals to industry and consumers, the transport sector’s behavior is highly inelastic in that it does not change significantly in response to changes in fuel prices, at least in the range that is politically acceptable.
