Ambitious climate policy can limit global temperature increase to 2 degrees

The EU target of limiting global temperature increase to 2 degrees can only be achieved with high certainty when greenhouse gas concentrations stabilize at low levels. Required emission reductions are technically feasible at a likely range of direct costs in the order of 1-2% of global GDP. This will require immediate action and ambitious climate policy, a broad range of options and worldwide participation in mitigating greenhouse gas emissions.
