New York will soon be the biggest state to require biodiesel to be blended into its heating oil. Recent legislation says that starting in July 2022, petroleum-based heating oil sold in the state will get blended with increasing amounts of biodiesel. The goal of the move is to help New York get to its goal of lowering greenhouse gas emissions. Biodiesel industry advocates estimate that the fuel will cut New York’s annual petroleum diesel consumption by about 200 million gallons every year. That will drop the state’s annual carbon emissions by roughly one million metric tons. New York’s governor says the bill is a step toward meeting the goals of the state’s Climate Leadership and Community Protection Act. All heating oil sold in New York must have at least five percent biodiesel by July 1, 10 percent by 2025, and 20 percent by 2030. Blending requirements are already in effect in Long Island and New York City.
