Palm oil
Palm oil may endanger the carbon neutrality of the fuel if forest is cleared and swamps drained to make way for palm plantations. In response to this concern, Neste has joined the Round Table on Sustainable Palm Oil (RSPO) to certify that the palm oil is produced in a carbon-neutral, environmentally responsible manner. Neste purchases most of its palm oil from IOI, but requires a separate production chain for the RSPO-certified palm oil, in order not to create demand for rainforest destruction.
