The main political parties have let the green agenda slip in the past year despite environmental threats increasing, a report by the UK's major green groups has said.
The Fit for the Future study, which analysed the green performance of all three parties over the past year, said many politicians believed the economic downturn made action on the environment less of a priority.
But the review by the Campaign to Protect Rural England (CPRE), Friends of the Earth, Green Alliance, Greenpeace, National Trust, RSPB, The Wildlife Trusts, Woodland Trust and WWF said the public had not abandoned green issues - and MPs should not either.
The only way out of the downturn was an ambitious climate change strategy that addressed energy, transport, land management, housing and the economy, the second annual review of the parties' performance said.
The three parties must drastically improve their green performance in the run-up to the next election, the environmental organisations urged.
The Labour Government's approach to the environment had become "incoherent and contradictory", the report said.
On the upside, the Government had introduced the Climate Change Bill and a draft strategy on renewable energy but there were concerns about the failure to rule out a new coal-fired power station at Kingsnorth, Kent, and Gordon Brown's trip to Jeddah to plead for higher oil production.
The Government won praise for protecting the natural world through measures such as the Marine Bill, avoiding a badger cull and protecting Lyme Bay from damaging fishing practices. But the green groups said the Government should have used rises in fuel prices to push through a reduction in the UK's dependence on fossil fuels, and criticised the "inadequate" action on biofuels.
The Conservatives came under fire for an "increasingly alarming" gap between their green aspirations and commitments, and for failing to mention the environment or climate change in their statement on priorities for a future government following the May elections. The party was also criticised for its negative attitude to green taxes and for sidelining its quality of life review which set out a green agenda, but they did win support for saying no to dirty coal.
Even the Liberal Democrats, traditionally strong on the environment, have seen their lead on green issues "wane" at points during the year. But they were applauded for Nick Clegg's commitment to making the UK energy independent and zero carbon by 2050, a move which was described in the report as "brave and bold", and for strengthening the Climate Change Bill.
