Green Olympics a lasting legacy: UN

China fulfilled many of its pre-Olympics commitments to improve the quality of air in Beijing and make the city greener, a United Nation's report released yesterday said.

In some cases, authorities had surpassed their targets before the 2008 Olympics and the Games would leave a lasting environmental legacy, said the United Nations Environment Program (UNEP) report released in Kenya at the UNEP Governing Council meeting.

The organizers made major efforts to ensure that the Games marked a step forward in terms of an eco-friendly, mass spectator-event, it said.
