New Zealand simplifies Road User Charges system, extends exemption for light electric motor vehicles from 2013 to 2020

(Since some 36% of diesel is used off-road, such as on farms, by manufacturing, industrial and commercial ventures, and boats, a fuel tax for road use would impose an unfair burden onto these sectors, the government says.). This is equivalent to the two cent per liter increase in gasoline excise duty that will occur on the same day.

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

The economy-wide CO 2 prices applied increase the cost of driving only marginally with respect to the business-as-usual case. 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. —Morrow et al.

Average on-road fuel consumptions (tank to wheels) of the different propulsion systems in an average light-duty vehicle: 2010, 2030, and 2050. Values normalized to standard naturally-aspirated gasoline engine vehicle. Market-based incentives should be implemented to support the US Corporate Average Fuel Economy (CAFE) LDV requirements.
