N.Y.C. Admin. Code § 28-320.3.6.2: § 28-320.3.6.2 Deductions from reported annual building emissions for purchased greenhouse gas offsets.

For calendar years 2024 through 2029, a deduction shall be authorized for up to 10 percent of the annual building emissions limit. Such a deduction shall be authorized only where within the reporting calendar year, greenhouse gas offsets equivalent to the size of the deduction as measured in metric tons of carbon dioxide equivalent and generated within the reporting calendar year have been (i) purchased by or on behalf of the owner in accordance with an offset standard referenced by rules of the department, (ii) publicly registered in accordance with such offset standard, and (iii) retired or designated to the department for retirement. Such greenhouse gas offsets must exhibit environmental integrity principles, including additionality, in accordance with rules promulgated by the department in consultation with the office of long-term planning and sustainability. For the purposes of this section, additionality means a requirement that an offset project is not already required by local, national or international regulations. Prior to the department promulgation of rules pursuant to this section, the department shall consult the advisory board on environmental justice as established by section 3-1006 of the administrative code.
