Local Law 97: Environmentalists split as Adams admin rolls out finalized rules for landmark climate law

The Adams administration has formalized long-awaited rules governing the landmark climate statute Local Law 97, with two weeks before the city’s largest landlords must begin complying with the law.

The publication crystalizes a set of rules proposed by the Department of Buildings (DOB) back in September related to the 2019 law, which requires Big Apple buildings over 25,000 square feet to meet strict regulations on carbon emissions starting next month, and to retrofit their buildings to meet those requirements lest they be hit with financial penalties. Buildings are the city’s largest source of carbon emissions, clocking in at about 70%, with an outsize amount of pollution caused by the largest properties.
