A spokeswoman said: "While the LCCA has helped raise London’s profile on climate change, it has not been the most effective or efficient way to cut carbon dioxide emissions."
There was "poor stakeholder perception with LCCA effectiveness", the LDA said. Better value for money and the need for a new approach to achieve mayor Boris Johnson’s carbon reduction targets were also factors behind the decision.
The LDA says it has already identified a "pipeline of projects" that will save 110,000 tonnes of carbon emissions a year. However, it would not give details of any.
A budget of £72 million over the next four years has been proposed for the LDA’s climate change work. It will prioritise waste, decentralised energy and energy efficiency in existing buildings to achieve carbon cuts. It believes these offer the best return on investment. The budget will be finalised in February.
