This report evaluates the impact of transportation policies on worldwide oil consumption and greenhouse gas (GHG) emissions and the potential for the reduction of both out to 2030. Its analysis finds that policies adopted and formally announced since 2000 will dramatically reduce oil consumption and GHG emissions from the transportation sector.

This roadmap explores the potential improvement of existing technologies to enhance average fuel economy of motorised vehicles and provides recommendations to reduce the average fuel economy of road motorised vehicles by 30% to 50% by 2030.

This report highlights a problem currently being experienced by new Euro IV and V heavy-duty trucks and buses: Despite meeting more stringent regulatory standards for exhaust emissions during type approval, many vehicles equipped with selective catalytic reduction (SCR) systems have significantly elevated emissions of nitrogen oxides (NOx) durin

Worldwide, commercial vehicles are the largest growing contributor to air pollution, fuel consumption, and global warming emissions in the on-road transportation sector.

To support development of a European Union (EU) strategy for reducing greenhouse gas (GHG) emissions from the heavy-duty vehicle (HDV) sector, the report entitled “Reduction and Testing of Greenhouse Gas (GHG) Emissions from Heavy Duty Vehicles – Lot 1: Strategy” was prepared for the European Commission by AEA and Ricardo.1 The report itemized t
