Olympic bid yields raft of environmental measures

China aims to speed up its environmental protection - especially the reduction of smog in and around Beijing - in its push toward winning the 2022 Olympic Games.

Clean energy will be developed and eco-friendly technologies will be used extensively in the coming years in Beijing and surrounding cities, according to Olympic candidacy files that were released on Monday.

Measures to protect forests, wetlands and the atmosphere will improve the environment in Beijing and Zhangjiakou, and elevate air quality in 2022 to WHO standards.
