Was the London Olympics a success? Many people hold different opinions．However, one thing is certain, London could win a gold medal for hosting the“greenest”Games ever, BBC News reported．
Previous Olympic hosts have been criticized for the environmental damage they have caused through construction, waste and transport．But things had to be different in London．
What is most impressive is that London considered the construction of the Olympic Park as an opportunity to clean up polluted areas．2 million tons of polluted soils were removed and 200 old factory buildings were torn down, according to sustainablebusiness．com．But that’s not all．99 percent of the debris（废瓦砾）were reused to build the Olympic Park．
As well as using recycled materials, all gymnasiums were built with green building techniques．The Olympic Stadium is the lightest one ever built, which minimized the amount of steel and concrete needed．Also, the handball field has lighting pipes on the roof that reduce electricity use by 40 percent．
The effort that London made to deal with waste also deserves praise．Water used for drinking and watering plants was from collected rainwater or recycled wastewater．In this way, about 30-40 percent less water was used in total．Waste food package were either recycled or processed and turned into renewable energy．
As one of the best connected places in Europe, London tried to solve traffic jams by encouraging the use of public transport．For example, it had trains deliver half of the building materials, instead of cars, which greatly reduced carbon emissions（排放）．
The clean anti-doping result also added to the greenness of the Games．Only one athlete tested positive for a banned drug on the day of competing, which is why the IOC President, Jacques Rogge, has praised anti-doping efforts at the London Games．
