The U.S. Environmental Protection Agency and the U.S. Department of Transportation's National Highway Traffic Safety Administration recently published the final Phase 2 rules targeting fuel consumption and greenhouse gas emissions attributable to new heavy-duty vehicles and engines.

This report compares the fuel efficiency of 20 airlines operating nonstop flights between the mainland United States and East Asia and Oceania. It extends the previous transatlantic fuel efficiency methodology to the transpacific market.

In the European Union, CO2 emissions from commercial vehicles grew much faster than from passenger vehicles from 1990 to 2014. Trucks and buses now produce about a quarter of CO2 emissions from road transport in the EU, and that share is growing as emissions from cars and vans decline further to meet increasingly tight CO2 standards.

China finalized its New Energy Vehicle (NEV) mandate in September 2017. The NEV mandate is a modified version of Californiaʻs Zero Emission Vehicle (ZEV) mandate, with goals of promoting new energy vehicles and providing additional compliance flexibility to the existing fuel consumption regulation.

Ships are an efficient way to move cargo, transporting approximately 80% of the world’s goods by volume, but ships also threaten human health, ecosystems, and the climate. This report focuses on the air and climate pollutant black carbon (BC).

In August 2017 the government of India published final fuel-efficiency standards for commercial heavy-duty vehicles. The standards are the government’s response to India’s rapidly growing commercial vehicle sector.

As vehicle pollution and fuel efficiency regulations have become more stringent, the technologies required to mitigate emissions and reduce fuel consumption become increasingly complex.

The State Road Transport Undertakings (SRTUs) provide bus-based public transport to urban and rural population of the country.
