Recent life - cycle analyses indicate that the fuel could reduce greenhouse gas emissions by up to 95 percent compared to fossil fuels, said Counsell.

The study is not a life cycle analysis, so it is also important to remember that fossil fuels used to transport oil palm products and emissions from the processing plants also produce greenhouse gases to the atmosphere.
