Jakarta, September 6 - Indonesia is capable to reduce greenhouse gas emission by 2.3 gigatons in year 2030, or equivalent to 46 percent reduction in year 2005.

It was the result of comprehensive study conducted by the National Council on Climate Change (DNPI) with 2005 latest data.

The result of the study was familiarized directly by DNPI executive chairman Rachmat Witoelar in the company of the DNPI secretary Agus Purnomo here on Monday.

In that comprehensive study, they analyzed present day greenhouse gas emission and its reduction potential in eight sectors of development with an estimation of greenhouse 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 greenhouse gas emission in 2030 would rise by 3.2 gigatons.

The eight development sectors in the study covered peatland, forest, agriculture, energy, transportation, oil and gas, cement and building.

Agus Purnomo said peatland and forest had the biggest contribution in greenhouse gas emission in Indonesia.

Emission from peatland which is rich in carbon contributes 41 percent of total emission in Indonesia in 2005.

Agus said the primary initiative to reduce emission from those sectors was by slowing down deforestation and decomposing of peatland, better management of forest, reduction of land clearance through incineration, and the use of degraded land for agriculture.

“Now that we have known where we should reduce greenhouse gas emission and its costs, we should no longer discuss it abstractly,” he said.

He explained that one of the most important achievements in DNPI's study was to clarify and quantify the importance of land use and transfer of land use in present Indonesian emission map.
