A Finnair Airbus A330 was scheduled to make its Helsinki-to-New York City flight on Tuesday powered by recycled cooking oil, coinciding with the UN Climate Summit taking place in New York. The environmentally sustainable biofuel from SkyNRG Nordic is manufactured in part from cooking oil recycled from restaurants. According to Finnair, switching to a more sustainable fuel source can reduce an aircraft's net carbon dioxide emissions by 50 to 80 percent. The airline first flew with such a fuel in 2011, but because it is currently more than twice the price of conventionally produced jet fuel, using the biofuel on a regular basis isn't yet economically viable. "The UN Climate Summit is an important gathering to fight climate change, and we wanted to take this opportunity to highlight the climate benefits of more widespread adoption of environmentally sustainable biofuels in aviation," noted Finnair's vice president of sustainable development, Kati Ihamäki, in a press release. "Finnair is committed to working further with industry partners and government bodies alike to help develop the biofuel supply chain and bring down the cost of sustainable biofuel for everyday use." Along with its partners, Finnair currently is investigating the possibility of a biofuel hub at Helsinki Airport.
