The Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends Report is published annually to summarize trends in EPA’s best estimate of real-world tailpipe carbon dioxide (CO2) emissions and fuel economy, and associated technologies.

EPA and the National Highway Traffic Safety Administration (NHTSA) jointly established a National Program consisting of standards for light-duty vehicles that reduce greenhouse gas (GHG) emissions and improve fuel economy.

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

Reveals that the efforts made by multiple Transport Task Group (TTG) countries to promote and support policies and programs—including stringent tailpipe emissions standards, fuel economy standards, low sulfur fuels, and green freight programs—are in good alignment with the long-term perspective and pathways of the Transport Task Group defined in

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

Global greenhouse gas (GHG) emission and fuel economy standards for light-duty vehicles (LDVs) have progressed significantly in a little more than a decade. Ten years ago, only four governments had introduced mandatory GHG emission/fuel economy standards: China, Japan, South Korea, and the United States.

Analyzes emerging vehicle-efficiency technologies with respect to cost and capacity to lower carbon emissions from passenger cars and light-duty trucks in the 2025–2030 time frame.

While the average fuel economy of vehicles continues to improve, a new analysis by the Global Fuel Economy Initiative (GFEI) highlights that the rate of progress has slowed in recent years.

The share of the world's electricity generated by coal is expected to fall to about 30 percent from approximately 40 percent in 2015 as the use of lower-emission energy sources including natural gas, nuclear and renewables increases says this report.
