Mayor Bloomberg’s PlaNYC initiative seeks to reduce New York City’s greenhouse gas emissions by 30 percent by 2030.

Many new sustainable technologies have recently come to the marketplace that help offset these emissions, increase a building’s efficiency, decrease energy dependence, and reduce costs for homeowners. Here you will find resources that review these technologies, describe the benefits they offer, and explain how they can be used within New York City.
