China sets new car exhaust emission standards
The State Bureau of Quality and Technical Supervision (SBQTS) of China recently promulgated a set of new standards on
car exhaust emissions.
The new standards will become effective as of January 1, 2000 in an attempt to allow a longer period of preparation
for existing car producers.
The new standards are made according to the car exhaust regulations of the UN Economic Commission for Europe and
exhaust emissions of new cars in China will be similar to the standard of European countries in the early 1990s upon
operation of the new standards.
China now has approximately 13 mm motor vehicles, and the number is expected to exceed 20 mm by 2000.
Urban air quality reports regularly released by the State Environmental Protection Administration show that auto
emissions have become a main source of air pollution in some major cities.
Environmental experts estimate that the annual emission of harmful gas by motor vehicles across China can reach tens
of millions of tons.
