FACTBOX: EU agrees mandate for Copenhagen climate talks

BRUSSELS (Reuters) - European Union leaders agreed an offer on Friday to put on the table at global climate talks in Copenhagen in December.

Here is a summary of what that agreement includes.

* The European Union will strengthen planned emissions cuts to 30 percent below 1990 levels by 2020 if a strong deal is reached at Copenhagen, provided other nations take similar steps.

* The European Union estimates that the total costs of mitigation and adaptation in developing countries could amount to around 100 billion euros ($148 billion) annually.

This will be to be met through a combination of developing countries' own efforts, the international carbon market and international public finance.

* The EU estimates the overall level of the international public support required is in the range of 22-50 billion euros per year by 2020, subject to fair burden sharing at the global level.

* The EU stresses that "fast-start" international public support is important in the three years before any Copenhagen deal takes effect.

Leaders acknowledge a European Commission estimate that developing countries will need 5-7 billion euros per year in the period 2010-2012, after which the agreement is due to kick in. An EU contribution will be determined after the Copenhagen talks.

* EU leaders call upon all parties to try to prevent global temperatures from rising beyond 2 degrees Celsius above pre-industrial temperatures. Developed countries should cut emissions to 80-95 percent below 1990 levels by 2050.

* EU leaders note that an excess of the so-called AAU carbon permits assigned under the Kyoto Protocol must be addressed in a non-discriminatory manner, treating European and non-European countries equally.

The handling of the AAU surplus should not affect the environmental integrity of a Copenhagen agreement.
