The mayor's announcement follows an EDF report last month showing that just one percent of New York City's buildings -- those burning the dirtiest grades of heating oil -- produce more pollution than all the city's cars and trucks combined.
"Mayor Bloomberg's pledge to green the dirtiest types of heating oil is one of the biggest steps New York can take to reduce soot pollution linked to asthma and heart disease," said Isabelle Silverman, an attorney for Environmental Defense Fund. "The dirtiest grades of heating oil must be phased out by 2020. Ten years is a long enough timeframe for buildings to convert and get the best use out of the older burners that can't burn cleaner fuel right away."
More information on toxic heating oil is available on the EDF Website.
