Quito (Ecuador): The upcoming Olympic Games in London will be the greenest in history due to the environmental actions taken for the construction of facilities, the British ambassador to Ecuador has said.

Linda Cross told the Andes news agency that low-cost buildings are being constructed for the London Olympics and that 97 percent of the materials used were recycled.

This has minimized spending in monetary as well as environmental terms, the Prensa Latina news agency reported.

Cross said the Olympics will leave a legacy for Londoners for the next 20 years, including new stadia, houses and improved public transportation. (IANS)
