Poland has signalled its opposition to an EU plan for deeper carbon emission cuts, which environment ministers will discuss on Friday.
 
Denmark, currently steering EU negotiations, is backed by the UK in calling for a 25% cut in CO2 emissions by 2020. Previously the target was 20%.

But Poland, reliant on coal for more than 90% of its electric power, fears the move would make energy more costly. Coal and other fossil fuels emit CO2, seen as a catalyst for climate change.

Poland's Gazeta Wyborcza newspaper says that "tomorrow Poland is ready to veto the EU plan to reduce CO2 emissions". 
 
Poland's Environment Minister Marcin Korolec has sent a letter to his EU colleagues urging them to reject the 25% target, the Financial Times newspaper reports.
