Mayor Bloomberg introduced a plan Wednesday that will provide $100 million in funding to help building owners convert to environmentally-friendly heating systems.

The Mayor made the announcement at the Eastchester Heights Apartments in the Bronx, which used to be one of the city's biggest users of heavy oil but recently began using natural gas.

Regulations were put in place last year banning two heavy heating oils that are still used in more than 10,000 buildings.

The mayor says those oils contribute to air pollution and health conditions like asthma.

"This is the air we breathe today being influenced," Bloomberg said. "This is the water that we drink every day. All of these things have an impact on us and our children and how we live."

The move is part of Bloomberg’s PlaNYC goal to reduce soot pollution by 50 percent by 2013.
