Sapporo, Japan July 8: Prime Minister Manmohan Singh is expected to counter US pressure to commit India to a 50 per cent cut in greenhouse emissions when he meets US President George W. Bush on Wednesday by telling the Americans that developed nations should go first because they had created the problem. The political declaration of the G-5 nations (India, China, Brazil, Mexico and South Africa) issued here Tuesday evening took a strong stand on various issues, including energy and food security. On climate change it spoke of the "historical responsibility" of developed nations in any long-term plan to reduce greenhouse gases. The G-8 wants all nations to commit to a 50 per cent reduction in emissions by 2050. India rejects this demand. "It is for those who have generated greenhouse gases that are in the environment today to take cuts to reduce gases. It's not for developing countries (to do so). Our emissions are minuscule. It is not for us to make long-term binding commitments," foreign secretary Shiv-shankar Menon said.
