After failing to meet renewable enery targets, the ODA has had to pump over 拢1m into energy efficiency for schools and housing

The Olympic Delivery Authority has had to pump over 拢1m into energy efficiency for schools and housing in order to meet the Olympic park鈥檚 carbon reduction targets.

It has confirmed it has failed to meet its renewable energy targets, and has had to find alternative ways of curbing its emissions, as revealed by 好色先生TV in February.

Last week the body said 9% of the park鈥檚 electricity would be generated from renewable sources, rather than the 20% it had aimed at. It argued it would still be able to meet its aim of producing half the carbon emissions of a normal scheme by cutting energy waste in the surrounding boroughs.

Shaun McCarthy, head of the Commission for a Sustainable 2012, which oversees the Games鈥 green credentials, said that the Olympics would still be a triumph for green construction.

He denied that the ODA鈥檚 grant to surrounding London boroughs was similar to carbon offsetting of flights. 鈥淭he ODA鈥檚 alternative arrangements are robust. They are honouring their overall carbon targets,鈥 he said.

On Monday the commission published a report into the ODA鈥檚 sustainability targets. Plans for a wind turbine had to be jettisoned over health and safety fears, while alternative energy options were reduced after it signed a heating contract with an energy provider largely reliant on gas.

Nonetheless, the report said that the Olympics was 鈥渙n track鈥 to deliver sustainability.

A spokesperson for the Renewable Energy Association said the 9% figure was 鈥渟hocking.鈥 He said: 鈥淭he technology is there to be pretty much zero carbon.鈥

But Richard Jackson, principal sustainable development manager at the ODA, said: 鈥淭he Olympic park has set new standards in sustainability.鈥
