BRUSSELS, Nov 8 (Reuters) - Once a clear environmental leader, the European Union is likely to set a more cautious tone for the global debate on a U.N. climate deal when it unveils a new chunk of green energy law early next year.
Warsaw talks starting on Monday assemble almost 200 nations to prepare for a U.N. global pact, to be sealed in 2015, by extracting new promises on emissions cuts.
The EU draft law should make the European Union the first major bloc to outline binding environment and energy targets for 2030.
Goals for 2020 agreed by EU leaders in 2007 became an international benchmark for climate ambition.
Scientific opinion has since become more convinced mankind is to blame for changes to the climate, but the political focus has shifted from the environmental to the economic crisis, especially in Europe.
European Commission President Jose Manuel Barroso said Europe has concerns about the impact on competitiveness if it acts when others do not, but he dismissed as "obscurantist forces" those who question whether the climate threat is real.
"If it's not more urgent (than economic crisis), it's more important because it's an essential threat to our planet. We should not relax our efforts. For that we need a global commitment. In Europe, we have been front-runners," he told Reuters.
The EU is still the main group among developed nations urging governments to declare their emissions goals.
EU Climate Commissioner Connie Hedegaard said all countries must "present bold pledges" in time for a summit organised by U.N. Secretary General Ban Ki-moon next September, which is meant to ensure the 2015 deadline for a new global deal is met.
Host of this month's climate talks, EU member Poland, whose economy depends on polluting coal, is among those who have emphasised collective action, rather than leadership.
Polish Environment Minister Marcin Korolec says EU efforts have handed an excuse to bigger emitters to leave the work to a bloc that emits a mere 11 percent of global greenhouse gases.
"This tendency of some European politicians stressing that the EU is a leader is in my opinion counterproductive," Korolec said, adding this only encouraged others to be inactive.
SMALL PROMISES
The biggest greenhouse gas emitters China and the United States have pledged to curb carbon, but on a modest scale.
