Bangkok--13 Dec--UN The head of the UN’s regional arm for Asia and the Pacific says that active support to developing countries is key to global success in fighting against climate change. Speaking today at the climate change conference in Bali, Noeleen Heyzer, Executive Secretary of the Economic and Social Commission for Asia and the Pacific (ESCAP), recalled remarks two days ago at ESCAP by Secretary-General Ban Ki-moon that a breakthrough in Bali could happen only with the active participation of key developing countries in the Asia-Pacific region. Our challenge, said Ms. Heyzer, was how to support developing countries in undertaking such actions. She noted that developing countries will not be able to simultaneously achieve continued economic growth and take adequate climate action unless there is technology transfer. The active participation of developing countries is indispensable for stabilizing green house gas emissions. However, Ms. Heyzer noted, imposing quantitative targets would be scientifically and politically challenging as economic growth uncertainties would make it difficult to make reliable projections on the long-term emission levels. “The only way to actively engage developing countries in global action is to develop a market mechanism that helps climate change actions become compatible with the needs of countries to pursue rapid economic growth.” Ms. Heyzer pointed out that climate change represents one of the greatest market failures ever, as it is associated with negligence of the externality of economic growth.
