French President Nicolas Sarkozy is to meet eastern European leaders to try to agree on the European Union's ambitious climate change package.

Some countries have opposed deep cuts in carbon dioxide emissions because they claim they unfairly penalize their dependence on coal for energy.
The cuts also do not take account of the lower levels of earnings in their countries, the leaders say.
The EU plan aims for better efficiency and increasing renewable energy by 20%.
It wants to meet its proposed targets by 2020.
When Sarkozy sits down with the leaders of nine east European countries in Gdansk on Saturday, some of the keenest observers will be 300km away in Poznan at the UN-led climate negotiations.
Although the talks in Gdansk are not directly related to the meeting in Poznan they are seen as crucial to maintaining the credibility of Europe's leadership on climate change.
The EU has told the world that if a global deal is done, then they will cut emissions by 30%.
But the leaders of eastern Europe, including Poland and the Czech Republic, say these targets do not take account of their dependency on coal for energy and the lower levels of earnings in their countries.
The costs of carbon trading are a particular stumbling block for the eastern counties.
They want to soften the blow to their industries and their populations by giving away permits to emit carbon.
Brussels wants these permits to be auctioned off to the highest bidder saying that if you give them away for free, it would undermine Europe's emissions trading scheme.
There are indications that President Sarkozy will agree a compromise with the eastern European leaders, giving them more time to catch up with the rest of EU.
He wants the climate package completely finished before France hands over the presidency of the 27-nation bloc to the Czech Republic in January. (Source: BBC)
