facilities. It has implemented stricter energy-saving standards for newly-

installed coal-fired generating units. The efficiency and pollutant con-

trol levels of these units are on par with the most advanced international

standards. China has promoted clean end-use energy by replacing coal

with natural gas, electricity, and renewable energy. It has actively support-

ed clean heating in winter in northern China. It has made the use of natu-

ral gas more efficient in urban areas, as well as in industrial fuel, power

generation, and transport, and promoted natural gas combined cooling,

heating, and power (CCHP). It has launched a campaign to upgrade the

quality of refined oil products. In less than 10 years China achieved the

upgrading that took developed countries 30-plus years, and its refined oil

products are now of the best quality by international standards. As a re-

sult, vehicle pollutant discharge has been effectively reduced.

3. Building a green transport network

The transport sector is one that consumes a large amount of energy

and generates significant pollutant and greenhouse gas emissions. This
