The pace of vehicle electrification in China and globally hinges on how quickly electric vehicle costs decline.

Because of its abundant biofuel feedstocks, Indonesia has the potential to produce biofuels via a number of pathways, including using different technologies and feedstocks to create different fuels.

New fuel consumption limits for passenger vehicles are scheduled to take effect in India in FY 2022–23, and this paper examines the performance of manufacturer groups with respect to new passenger vehicles sold in FY 2019–20.

Despite years of sustained interest in sustainable aviation fuels (SAFs), the industry has been slow to expand in the face of strong economic barriers to deployment.

This briefing paper identifies several possible levels of stringency for the post-2021 CO2 standards in the European Union for light-duty and heavy-duty vehicles and compares them against economy-wide greenhouse gas reduction targets for 2030 and 2050, as well as the 2050 target for transport sector emission reductions in the EU Green Deal.

This briefing paper outlines a methodology for calculating well-to-wake CO2-equivalent emissions from four fossil marine fuels: heavy fuel oil, very low sulfur fuel oil, marine gas oil, and liquefied natural gas. Well-to-wake emissions, or life-cycle emissions, are the sum of upstream (well-to-tank) and downstream (tank-to-wake) emissions.

China’s fuel consumption standards for heavy-duty vehicles (HDVs) have progressed since Stage 1 was first introduced in 2012, and Stage 4 standards are currently in development.

This report provides the first bottom-up, detailed fuel consumption inventory for all commercial flights to, from, and between U.S. airports using our Global Aviation Carbon Assessment (GACA) model. The analysis finds that overall fuel burn and, therefore, carbon dioxide (CO2) emissions from U.S. airlines increased by 7% from 2005 to 2019.

This paper is designed to aid cities in accelerating the electrification of ride-hailing fleets to reduce their environmental impacts; it does not assess the complex advantages and drawbacks of ride-hailing platforms more broadly.

Although the majority of the on-road vehicle fleet in the United States is fueled by gasoline, diesel combustion makes up an overwhelming share of vehicle air pollution emissions. Air pollution emissions can be affected by blending biodiesel into diesel fuel.
