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.
Since the 1980s, China has implemented a series of policies and regulations to address harmful diesel emissions, and this report is a comprehensive overview of the best practices emerging from the Clean Diesel Program.
China took a big step toward further reducing in-use vehicle emissions when it released a final notice of the establishment and implementation of a vehicle emissions inspection and maintenance (I/M) program in June 2020.
China is considering options for increasing fuel efficiency and reduce CO2 emissions from freight transportation. This study assesses the future costs of existing and emerging technologies to reduce fuel consumption and CO2 emissions of long‑haul tractor‑trailers in China.
The China VI standard is among the world’s most stringent HDV emission standards and combines best practices from both European and U.S. regulations. It will be a key pathway to clean up diesel emissions and is therefore a critical step toward winning the war against air pollution in China.
On June 28, 2018, the Ministry of Ecology and Environment (MEE) of the People’s Republic of China released the final rule for the China VI emission standard for heavy-duty vehicles. The China VI standard will be implemented in two phases.
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.
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.
