Indonesia is capable of reducing green house gas emission by 2.3 gigatons in 2030, or equivalent to 46 percent reduction in 2005. It was the result of comprehensive study conducted by the National Council on Climate Change (DNPI) with 2005 latest data, according to a report circulated today by Indonesia's "ANTARA" news agency. The result of the study was familiarized directly by DNPI executive chairman Rachmat Witoelar in the company of DNPI secretary Agus Purnomo here on Monday. In this comprehensive study, they analyzed present day green house gas emission and its reduction potential in eight sectors of development with an estimation of green house gas emission in Indonesia in 2005 reaching 2.3 gigatons. If there was no change in the eight sectors of development, DNPI predicted that the total green house gas emission in 2030 would rise by 3.2 gigatons. The eight development sectors in the study covered peat land, forest, agriculture, energy, transportation, oil and gas, cement and building.
