Stop Climate Chaos coalition members WWF have enlisted the help of Britain's leading environmental scientists to call on political leaders to commit to tougher carbon emission cuts.
In the form of an open letter, published in five major UK newspapers and addressed to the leaders of the main UK political parties, the scientists are demanding that an 80% cut in CO2 emissions by 2050 must be included in the upcoming Climate Change Bill.
The brief text outlines how the Government's current target of a 60% is based on an out of date report by Royal Commission on Environmental Pollution (RCEP), which was first published in 2000.
The letter is signed by Sir John Lawton, the current Chair of the RCEP, his predecessors - Sir Tom Blundell (Chair at the time of the 2000 report) and Sir John Houghton - and Professor Norman Myers, Foreign Member of the US National Academy of Sciences.
"The Government has a unique opportunity to set an example to the rest of the world by introducing groundbreaking legislation on climate change," said David Nussbaum, chief executive of WWF-UK.
"Today some of Britain's most eminent climate and environmental scientists have added their voices to the growing calls for emission cuts based on the latest science - that means cuts of at least 80% by 2050," he added.
The open letter ran in today's The Times, The Guardian, The Telegraph and The Independent and will run in tomorrow’s Financial Times. The scientists signed the letter in their personal capacity.
The recent report, 80% Challenge: Delivering a low carbon Britain, published jointly by WWF-UK, Institute for Public Policy Research (IPPR) and the Royal Society for the Protection of Birds (RSPB), found that it is technically feasible and affordable for the UK to cut its CO2 emissions by at least 80% by 2050 - including our share of emissions from international aviation and without using new nuclear power.
