Urban transit bus fleets are a significant source of air pollutant emissions, including black carbon, a harmful ultrafine particle and potent short-lived climate pollutant. Transit bus fleets are therefore an important target for accelerated transitions to clean engine technologies and fuels.

Summarizes provisions of the implementing act adopted in May 2017 by the European Union for type-approval of CO2 emissions and fuel consumption of on-road heavy-duty vehicles, which will go into effect in 2019 and 2020.

This document outlines the current procedure for the determination of fuel consumption, carbon dioxide (CO2) emissions, electric energy consumption, and electric range, specifically for PHEVs in Europe, highlights the most relevant changes expected with the introduction of the new Worldwide Harmonized Light Vehicles Test Procedure (WLTP) and dis

Heavy-duty vehicles produce about a quarter of all carbon dioxide (CO2) emissions from road transport in the European Union (EU), and some 5% of the EU’s total greenhouse gas emissions. Their share is growing, as emissions from cars and vans decline in response to increasingly stringent CO2 standards for those vehicles.
