Indonesia's Environmental Minister Gusti Muhammad Hatta disclosed?in Jakarta?on Thursday that the cost, amount of emission reduction and sectors expected to contribute significantly to the government's emission reduction target initially set at 26 percent and 41 percent with the help of foreign assistance by 2020.

Gusti told local media that his ministry has formulated the action plans to achieve the carbon emission targets issued by President Susilo Bambang Yudhoyono in G20 meeting last year.

He said sectors that would be worked on to reduce Indonesia's emission would be comprised of Energy, Transportation Industry processes, Agriculture, Forestry, Waste and Peatland.

"Forestry and peat land would be the most significant sectors expected to reduce the emission rate,"Gusti said, adding that the reduced emissions in the two sectors expected to reach 0.392 Gt ( Giga Tons) and 0.280 Gt respectively.

With 26 percent reduction target scenario, reaching emission reduction at those levels in the two sectors by 2020, it would cost Indonesia some 30.4 trillion rupiah (about 3.3 billion U.S. dollars) for forestry and 16.5 trillion rupiah (about 1.7 billion U.S,. dollars) for peatland.

Meanwhile, under the 41 percent reduction target scenario, the minister said that with help of foreign funds, the government would be able to add the emission reduction by 0.310 Gt and 0.057 Gt in forestry and peat land sectors respectively by 2020.

In total, he said, the Indonesian government needs to allocate 83.3 trillion rupiah (about 8.9 billion U.S. dollars) to finance its 26 percent emission reduction target by 2020.

Meanwhile, with the help of foreign funds, the 41 percent emission reduction target scenario would cost some 168.25 trillion rupiah (about 18.1 billion U.S. dollars), Gusti said.
