South Korea today set an ambitious target for its voluntary cut in greenhouse gas emissions, expressing hope that other developing countries would follow suit. The cabinet vowed to cut emissions by 4 per cent by 2020 from the 2005 level, which it said was equivalent to a 30 per cent reduction on the basis of a business-as-usual development pattern.<br/>A statement said the targeted cut was the biggest recommended for developing countries by the Intergovernmental Panel on Climate Change, which called for reductions of between 15 and 30 per cent. Speaking at the cabinet meeting President Lee Myung-Bak said although a breakthrough is unlikely in the climate summit in Copenhagen next month, his country's move will set an example for other developing countries.<br/>
