Hydrofluorocarbons (HFCs) used in mobile air conditioning (MAC) and refrigeration equipment are an important contributor to greenhouse gas (GHG) emissions from motor vehicles. Estimates of emissions in China from the MAC refrigerant HFC-134a, conducted by Peking University, shows that they exceed 20 million tonnes of CO2 equivalent per year .

Tax policy can be designed to spur both the deployment of electric vehicles (EVs) and improvements in the fuel efficiency of internal combustion engine (ICE) vehicles.

This annual report is part of EPA’s commitment to provide the public with information about new light-duty vehicle greenhouse gas (GHG) emissions, fuel economy, technology data, and auto manufacturers' performance in meeting the agency’s GHG emissions standards.

The export of used light duty vehicles (LDVs) has increased significantly. In 2015, 3.4 million used LDVs were exported globally, by 2019 this had increased to 4.8 million. Most likely due to the covid-19 pandemic, there was a reduction of used LDVs in 2020 to 4 million.

This report presents the latest update to the Global Fuel Economy Initiative’s biannual benchmarking report on light-duty vehicle sales.

The gap between real-world fuel consumption and emissions of carbon dioxide from light-duty vehicles (LDV), and their laboratory values, is increasingly apparent around the world, including in China. ICCT has been tracking the gap between real-world and type-approval fuel consumption of LDVs since 2017.

With introduction of the EU’s first CO2 standard for new passenger cars, official type-approval emissions decreased at a rate of about 3.5% per year, compared to about 1.2% prior to regulation. The 2015 target of 130 g/km was met well in advance by manufacturers.

Applying the ICCT Roadmap Model, three scenarios were modeled to assess the required level of type-approval CO2 emission reduction for new passenger cars and vans: Adopted policies: Average new car CO2 emissions decrease by 15% by 2025 and 37.5% by 2030, relative to 2021. For vans, the reduction is 15% by 2025 and 31% by 2030, relative to 2020.

Air pollution poses a risk to human health at levels even below the emission limits established by the World Health Organization in Europe.

As part of the roadmap to achieve its climate-neutrality goal, the European Commission will come forward with a proposal for revised CO2 targets for new passenger cars and vans by the middle of 2021.
