A collaborative effort from the city’s leading building and energy stakeholders, the Blueprint calls for a 20 percent reduction in energy use by 2030, driving NYC buildings 36 percent of the way to their 80×50 target.  The Blueprint provides a practical policy framework to reduce emissions in large buildings by 2030, as well as the infrastructure to deliver improvements at scale through 2050. Twenty-one detailed proposals shape this world-leading energy performance policy.
