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.

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 publication analyzes the use of clean and efficient cooking technologies in the Philippines and identifies opportunities and challenges to fast-track their uptake. In Asia and the Pacific, 1.8 billion people still rely on traditional cooking methods using fires and solid fuels.

To support the development of stringent yet cost-effective fuel efficiency standards for Chinese passenger cars for the 2025–2030 time frame, this study evaluates the potential technology pathways for and incremental costs of meeting the preliminary fuel efficiency target outlined in Made in China 2025.

This paper provides the first comprehensive social welfare estimates of recent fuel economy and greenhouse gas emissions standards.

While heavy-duty vehicles (HDVs) are just 5% of vehicle sales in China, they consume nearly 50% of all on-road transport fuel.

Regulators are working toward an India-specific version of the European Commission’s Vehicle Energy Consumption Calculation Tool (VECTO), and its use in future fuel efficiency regulations would allow India to implement simulation-based standards that are more aligned with trends in other major vehicle markets.

The new light-duty CO2 standards require the European Commission to monitor the real-world fuel and electric energy consumption of light-duty vehicles. In order to do this, the European Commission must develop a procedure to transfer the data recorded by soon to be mandatory on-board fuel and energy consumption monitoring devices (OBFCM).

To address the danger that greenhouse gas (GHG) emissions from aircraft pose to public health and welfare, the U.S. Environmental Protection Agency (EPA) is set to propose an aircraft CO2 emissions standard.
