Triple-pane windows, heat pumps part of New York’s plan to meet 2050 emissions goal

Renovations providing better insulation, triple-paned windows, heat pumps and other techniques that minimize heat loss and save on energy use for residential and commercial buildings are key to New York City’s goal of reducing its carbon emissions by 90% by 2050. The "90 by 50" plan of the Urban Green Council seeks to reduce the city's carbon emissions through energy retrofits on existing buildings. The plan also calls for increased waste reduction and improved wastewater treatment.
