Palm oil biodiesel does not produce low GHG emissions. For fossil-based diesel replacements, biodiesel made from soybean, rapeseed or sunflower vegetable oils reduces GHG emissions more thanbiodieselmade from palm oil.

Untuk pengganti diesel, biodiesel berbahan baku minyak nabati kedelai, rapeseed atau bunga matahari lebih tinggi menghemat emisi GHG dibandingkan dengan biodiesel berbahan baku minyak sawit.

Various studies both in Indonesia and in Europe show that using Life Cycle Analysis, diesel-fuel replacement with palm biodiesel will reduce greenhouse gas (GHG) emissions from diesel engines by 50-60 percent.

Even according to the EuropeanCommission, if the palm oil biodiesel is produced from palm oil plantations with methane capture technology, the reduction of GHG emissions can reach 62 percent (Figure). The results of the studies made by Mathews and Ardyanto (2015) also support the European Union’s findings that the use of palm oil-based biodiesel as a substitute for diesel can lower GHG emissions by above 60 percent.

The reduction of GHG emissions caused by the use of biodiesel made from palm oil is higher than those from biodiesel made from rapeseed oil, soybean oil or sunflower oil. In other words, the use of palm oil-based biodiesel as a substitute for diesel can more greatly reduce GHG emissions than biodiesel made from soybeans, rapeseed or sunflower oil.

 

Berbagai penelitian baik di Indonesia maupun di Eropa, menunjukkan bahwa dengan menggunakan Life Cycle Analysis penggantian bahan bakar diesel/solar dengan biodiesel sawit akan mengurangi emisi gas rumah kaca dari mesin diesel sekitar 50-60 persen.

Bahkan menurut European Commission, apabila biodiesel sawit yang dihasilkan dari PKS dengan methane capture pengurangan emisi GHG dapat mencapai 62 persen (Gambar). Hasil penelitian Mathews and Ardyanto (2015), juga mendukung temuan Uni Eropa tersebut bahwa penggunaan biodiesel sawit sebagai pengganti diesel dapat menurunkan GHG di atas 60 persen.

Penghematan emisi GHG akibat penggunaan biodiesel berbahan baku sawit tersebut, lebih tinggi dibandingkan dengan penghematan emisi yang diperoleh dari biodiesel berbahan baku minyak rapeseed, minyak kedelai maupun minyak bunga matahari.

Dengan kata lain, penggunaan biodiesel minyak sawit sebagai pengganti diesel dapat menurunkan emisi GHG yang lebih besar dibandingkan dengan jika digunakan biodiesel berbahan baku kacang kedelai, rapeseed maupun minyak bunga matahari.
