Policies to reduce fuel consumption, air pollution, and carbon emissions from vehicles in G20 nations

This briefing paper reviews the status of motor vehicle energy efficiency and emissions control programs in G20 nations. These programs have four components: low-sulfur fuel standards; tailpipe emissions standards for new vehicles; fuel economy and CO2 standards for new vehicles; and voluntary Green Freight programs. The briefing also summarizes information on technology availability and costs, emissions reductions, and benefit-cost ratios.
