'Economic recovery and urgent action to tackle climate change are complementary - boosting the economy and jobs through investment in the new infrastructure needed to reduce emissions,' the Call states.

The statement calls for a plan towards 2020 and 2050 emission reduction targets, regulation for energy efficiency, standardized method for reporting emission performance, incentives for low emission technology development, and funds for adaptation and forest protection.

The Copenhagen Call will be taken forward into the six months of negotiations before the UN Climate Change Conference in December.
