Prime Minister Gordon Brown has set out the UK's first detailed position on an international climate change agreement. He urges world leaders to cut global greenhouse gas emissions by at least 50 percent by 2050 compared to 1990 levels. He also committed to providing financial aid for climate mitigation in the developing world.

It will cost an estimated $100 billion per year by 2020 to finance actions to reduce global emissions, adapt to climate change, implement green technologies and reduce deforestation. Economic benefits from converting economic activity away from producing greenhouse gases are significant.

Over 800,000 people are now employed in Britain's low carbon economic sector and over a million jobs are predicted by the middle of the next decade. A global deal is very important for the UK's economic future.
