NANJING, China Nov 29 (Reuters) - Pledges made so far by governments to cut greenhouse gases are not enough for an effective pact to fight climate change, European Commission President Jose Manuel Barroso said on Sunday.
Speaking to reporters in Nanjing, eastern China, just over a week before the start of U.N. climate talks in Copenhagen on Dec. 7, Barroso said, taken as a whole, the proposed curbs were encouraging.
However, he said they fell short of the minimum scientists believed was needed to avoid future temperature rises of 2 degrees Celsius or more above the pre-industrial average, which could lead to dangerous climate disruptions.
"If you sum up all the commitments made so far, according to our estimates, we are not yet where we should be if we want Copenhagen to succeed," said Barroso, who will attend a European Union-China summit in Nanjing on Monday.
"Everyone has a good reason not to do more, and it’s legitimate, but at the end if we just concentrate on the reasons not to do more, we’ll not achieve the necessary result."
The European Union has pressed for countries to agree on ways of cutting greenhouse gas emissions by 50 percent of recent global levels by 2050, a goal that scientists have said is likely to avoid temperature rises of 2C or more.
In July, the Group of Eight leading industrial countries failed to get the biggest developing countries plus China and India to sign up to the goal of halving world greenhouse gas emissions by 2050.
"I believe it should be possible and we are working for it, for the 50 percent by 2050," said Barroso. "Certainly, we would like to see that result, but it’s too soon to say if the different partners are ready."
The world’s biggest greenhouse gas emitter, China, said on Thursday it would try to slow its growing greenhouse gas emissions by aiming to cut the amount of carbon dioxide emitted to generate each unit of economic output by between 40 and 45 percent by 2020 compared with 2005 levels.
The United States has promised to cut 2005 emissions by 17 percent by 2020. EU leaders agreed in December 2008 to cut emissions by 20 percent below 1990 levels by 2020 and by 30 percent if other developed countries followed suit.
"What I can tell you is that I certainly ask the Chinese and all our partners for the outer limits of their positions," said Barroso.
