As part of New York City’s Climate Mobilization Act, Local Law 97 is groundbreaking legislation that aims to reduce greenhouse gas emissions from large buildings – those over 25,000 square feet – in NYC. This law, which came into effect in 2019, is a significant step towards achieving the city’s goal of an 80% reduction in greenhouse gas emissions by 2050.
