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. Note the different scaling used in the graphs.

Belfer Center Study Concludes Reducing Car and Truck GHG Emissions Will Require Substantially Higher Fuel Prices; Income Tax Credits for Advanced Alt Fuel Vehicles Are Essentially Ineffective at Reducing Sector Emissions

Green Car Congress

Direct transportation (fuel) taxes generate the greatest reductions in CO 2 emission from transportation, achieving CO 2 emissions at 86% of 2005 levels by about 2025. While CO 2 prices are equivalent to fuel taxes, CO 2 prices at their projected levels are far too small to create a significant incentive to drive less.

Energy Learning Curve Survey Finds Americans Support Wide Array of Proposed Energy Policies, But Are Not Yet Ready to Make Tradeoffs

Green Car Congress

At least 10 major energy proposals that would provide incentives for energy efficiency, reduce gasoline usage and support alternative energy have the support of more than two-thirds of Americans, according to a new survey, “The Energy Learning Curve” released by Public Agenda, an opinion research and citizen engagement organization.

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.

Proposed US Transportation Reauthorization Plan Links Greenhouse Gas Reductions to Transportation Planning

Green Car Congress

The Fund is replenished by revenue collected from motor fuel taxes. The situation has worsened with decreasing fuel purchases; the advent of more fuel-efficient vehicles in the future would also further stress the existing funding mechanism. Tags: Climate Change Emissions Infrastructure Policy.

MIT Energy Initiative report on transforming the US transportation system by 2050 to address climate challenges

Green Car Congress

Overall, we have substantial opportunities for reducing environmental and climate impacts from light-duty road vehicles. Average on-road fuel consumptions (tank to wheels) of the different propulsion systems in an average light-duty vehicle: 2010, 2030, and 2050. Includes vehicle weight reduction: at constant acceleration capability.
