There is growing evidence globally and in China of the gap between laboratory test findings and real-world carbon dioxide (CO2) emissions and fuel consumption.

The number of electric and plug-in hybrid cars on the world’s roads exceeded 3 million in 2017, a 54% increase compared with 2016, according to the latest edition of the International Energy Agency’s Global Electric Vehicles Outlook. China remained by far the largest electric car market in the world, accounting for half sold last year.

This white paper provides a detailed assessment of light-duty electric vehicle sales and manufacturing, including the associated battery production and its suppliers. Analyze where electric vehicle models are being assembled and where their battery cells are being produced, and compare that to where the consumer markets are developing.

Vehicle emissions control programs in China have made considerable progress, mainly attributed to the uptake of emissions control technologies driven by increasingly stringent standards and improved fuel quality. Nevertheless, challenges remain regarding compliance with emissions standards for vehicles under real-world driving conditions.

This report provides a comprehensive overview of vehicle remote sensing, an emissions measurement technique which has been used for more than 25 years to evaluate emissions from passing motor vehicles in real-world driving.

All car and van manufacturers met their carbon dioxide (CO2) specific emission targets in 2016, based on current European vehicle test rules, but they will need to continue their efforts to meet future agreed-to cuts.

On November 8, 2017, the European Commission (EC) published its regulatory proposal for post-2020 carbon dioxide targets for new passenger cars and light-commercial vehicles (vans). The proposed regulation would be the third set of mandatory vehicle CO2 performance standards in the European Union (EU).

At the North American Leaders Summit (NALS) in June 2016, the heads of the governments of Canada, Mexico, and the United States agreed to “commit to reduce air pollutant emissions by aligning air pollutant emission standards for light- and heavy-duty vehicles and corresponding ultralow-sulfur fuel standards by 2018.” To support regulatory effort

Vehicle size and weight has evolved significantly in the last decades, with vehicle getting larger, taller and substantially heavier. The evidence gathered in this paper shows that the growing share of SUVs is drastically accelerating the size and weight increase trends and threatens the EU CO2 improvement rates.

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.
