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).

US COVID-19 mitigation efforts resulting in significant decline in traffic, emissions and fuel-tax revenues

Green Car Congress

This puts the US on track to meet its annual goals for GHG reduction under the Paris Climate Accord. If traffic remained reduced for one year, the reduction in VMT would allow California to meet half of its 2050 climate change target. Fuel use dropped from 4.6 It also resulted in fuel-tax revenue reductions, which vary by state.

Study finds higher gasoline taxes do not disproportionately impact the poor, especially in developing countries

Green Car Congress

However, a new study by researchers at the University of Gothenburg (Sweden) finds that middle- and high-income earners are generally affected the most by gasoline taxes, especially in poor countries, rather than poor people. Sterner is lead author in the UN climate panel’s (IPCC) working group Mitigation of Climate Change.

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

Green Car Congress

Policies to entice consumers away from fossil-fuel powered vehicles and normalize low carbon, alternative-fuel alternatives, such as electric vehicles, are vital if the world is to significantly reduce transport sector carbon pure-emissions, according to a new study. Note the different scaling used in the graphs. McCollum et al.

OECD: governments should make better use of energy taxation to address climate change; “meaningful” increases limited to road sector

Green Car Congress

Taxes are effective at cutting harmful emissions from energy use, but governments could make better use of them. Tax rates were below the low-end estimate of climate costs (EUR 30/tCO 2 ) for 97% of emissions. These changes mainly result from fuel tax reforms in China, India and Mexico, the report said.

National Academies report finds US interstate highways need major overhaul; calls for 20-year blueprint for action

Green Car Congress

The report calls for a 20-year “blueprint for action,” which includes creating an “Interstate Highway System Renewal and Modernization Program,” increasing the federal fuel tax to help pay for it, and allowing tolls and per-mile-charges on more interstate routes. The study was sponsored by the US Department of Transportation.
