The UN and Eruopean Union (EU) officials at the Copenhagen Climate summit have welcomed the US declaration that green house gases are threatening to human health. An EU spokesman said, the announcement shows a degree of resolve on the part of President Barack Obama to address climate change. United States' main environmental agency has declared that greenhouse gases are endangering the health of American people. The ruling made by the Environmental Protection Agency, EPA, said Mr. Barack Obama could order cuts in emissions without the approval of the U.S Senate. At the moment, legislation restricting carbon emissions is tied up in the Senate where it faces stiff opposition, both from those who say restrictions will cost the United States in jobs and push up energy prices and those who simply do not accept that climate change is real or man-made.<br/><br/>Chairman of the UN Scientific Network on Climate Change, Mr. Rajendra Pachauri said, the Obama Administration is showing what it can do even while legislation is pending. Sweden's Environment Minister, Andreas Carlgren said, the outcome of the Copenhagen summit depends mostly on what will be delivered by the United States and China. Meanwhile, British Prime Minister Gordon Brown has said that he wants European leaders to commit deeper cuts in carbon emissions than previously agreed. About 100 leaders from 192 countries are participating in the talks at the summit to discuss emission cuts and financial measures to combat climate change.<br/><br/>Meanwhile, India said that it is not acting under pressure to help work out a new agreement and would stick to fundamental elements of its stated position on the issue even as delegates from 193 nations began tough negotiations on a climate change deal in Copenhagen. The crucial summit on climate change opened at Copenhagen with a call for early action to combat the threat of climate change. Danish Prime Minister L. L. Rasmussen has described the UN climate summit as an opportunity the world cannot afford to miss. Opening the two-week conference in the Danish capital, he told delegates from 193 countries that a strong and ambitious climate change agreement is the need of the hour. AIR correspondent reports that negotiators from about 100 countries are participating in the first round of discussions to prepare a draft for the ministerial level meeting. <br/><br/>Prime Minister's Special envoy on Climate Change, Mr Shyam Saran said Indian government is not acting under pressure from the international community with regard to its decision to reduce carbon emissions by 20 to 25 per cent by 2020. Talking to media-persons he said one should be aware of the fact that there are certain fundamental elements that should not change. In terms of those fundamental principles the Indian stand has been quite consistent. Mr Saran highlighted these fundamentals as – the principle of common but differentiated responsibility, the legally binding quantitative emission reduction targets obligations are on developed countries not on developing countries, and mitigation action being taken voluntary by developing countries should be supported by financial resources and technology.<br/><br/>Earlier, allaying fears of the members in the Rajya Sabha, environment Minster Jairam Ramesh renewed the pledge of not accepting any legal binding on emission cuts. He said New Delhi will not compromise country's national interests while negotiating at the summit.
