Although Christmas and a cold winter are upon us, there is good reason to reflect on global warming and the recent climate change conference in Cancun, Mexico. It may seem unreal in Europe now when our teeth are chattering, but 2010 was actually one of the hottest years on record.

Weather-related catastrophes, from fires in Moscow to floods in Pakistan and Venezuela are a forewarning of things to come, unless we deal with the challenge of climate change. That's why the package of decisions that came out of the conference in Cancun may well be this year's most important Christmas present.

What is in the package? Quite a bit. And Europe can be proud of having contributed significantly to the content.

The key points of the agreement concluded in Cancun are based on the results we achieved in Copenhagen last year, including the 2 C target and the pledges that countries made in the run-up to Copenhagen. It comprises the commitment of developed nations to provide finance for developing countries - $30 billion in the short term (2010-2012) and $100 billion annually by 2020. And it includes the rules for transparency - how countries measure and report their emissions. The last point may sound a bit technical, but in fact it is very political, as the rules are key to ensuring that countries deliver on their promises.

We also need the rules to be able to assess the impact of climate projects in developing countries that are financed with European taxpayers' money. In Cancun, all countries - except for Bolivia - agreed to what was agreed in Copenhagen.

But Cancun also took new steps. Besides tightened rules on transparency, the agreement contains detailed decisions for improved cooperation on technology between North and South, an agreement on climate adaptation in developing countries and a mechanism to reverse deforestation in the Tropics. These are substantial decisions that will lead to concrete action, and decisions with a clear European fingerprint.

For example, Andreas Carlgren, Swedish environment minister, and his counterpart from Grenada were appointed to fine-tune the wording of the agreement's overarching shared vision. Along with Algeria, Spanish State Secretary Teresa Ribera forged the compromise on adaptation. In cooperation with Brazil, Chris Huhne, British secretary of state for energy and climate change, was asked to handle the delicate issue of the future of the Kyoto Protocol and find out how to anchor the reduction pledges from Copenhagen in the new agreement. And the newly appointed environment minister of France led the consultations on technology.

In other words, Europe played a key role in the political stage of the negotiations. We have strived to push things forward at the technical level with a steady stream of analyses, text input and suggestions, and in relation to the strategy.
