New York City took another step toward a greener future last week when the City Council voted overwhelmingly to pass the Clean Oil Heating Bill sponsored by Councilman Costa Constantinides (D-Astoria). The legislation ensures more sustainable energy consumption by increasing the use of biodiesel fuel in home heating oil from the current standard of 2 percent to a 5 percent blend by October 2017 and then raises that blend up to 20 percent by 2034 on an incremental basis.
