The ICCT commissioned the Institute for Internal Combustion Engines and Thermodynamics of the Graz University of Technology (TU Graz) to conduct track and chassis dynamometer testing to determine the aerodynamic drag, pollutant emissions, and fuel consumption of three European heavy-duty vehicles.

The US EPA is pursuing a rollback of earlier plans (implemented under Obama’s presidency) to raise the new-vehicle fuel-efficiency standard to nearly 50 miles per gallon by 2025 (that would be a fl

The CO2 certification procedures for HDVs in the EU and the United Stated use a combination of component testing and vehicle simulation to assign official CO2 emission and fuel consumption values.

The 2018 Toyota Camry incorporates eight technology upgrades that are specifically modelled in the U.S. Environmental Protection Agency’s Optimization Model for Reducing Emissions of Greenhouse Gases from Automobiles (OMEGA) and Lumped Parameter Model (LPM).

International climate talks in Paris set an ambitious goal: limiting global warming to 2°C by 2100. Reaching that goal will require investing an additional $1 trillion per year until 2050 in clean energy and other sustainability projects.

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).
