T I M E L I N E S Compliance Cycles: Covered buildings must comply annually starting in 2024 with emissions limits becoming increasingly stringent every five years through 2049. In 2050, all buildings will have to meet zero emissions criteria. Article 321 Prescriptive Path Deadline DECEMBER 2024 Article 321 buildings must either: a) complete required list of prescriptive energy conservation measures; or b) meet their 2030 carbon limit in 2024. First Compliance Reports due MAY 2025 Due by May 1st each year, the reports will detail a buildings emissions in the prior year and whether the laws requirements were met. City Operations 40% Target JUNE 2025 By fiscal year 2025, there must be a 40% reduction in emissions from city government operation below fiscal year 2006 OBEEP Report on Compliance JANUARY 2026 OBEEP must submit report to mayor on compliance of covered buildings under the law. Subsequent report due annually. 2030 Compliance Pathway Begins JANUARY 2030 New, stricter emissions limits are place on covered buildings for calendar years 2030-2034 Lower Electricity Carbon Coefficient After 2030, the carbon associated with a buildings electricity use will be lowered under the law. This step reflects the projected timeline for a lower- carbon grid powered by renewable energy in NYS. NYCHA Housing 40% Target NYCHA must make best efforts to reduce greenhouse gas emissions by 40% below 2005 levels Rent-Regulated Compliance Begins Buildings with at least one and not more than 35% rent regulated units must begin complying with laws carbon caps. City Operations 50% Target JUNE 2030 By fiscal year 2030, there must be a 50% reduction in emissions from city government operations below fiscal year 2006. 2035 Compliance Pathway Begins JANUARY 2035 New, stricter emissions limits are place on covered buildings for calendar years '35-'39 Electricity Carbon Coefficient TBD The amount of carbon a building must account for will be refined again in line with projected renewable energy deployment. Income-Restricted Housing Compliance The amount of carbon a building must account for will be refined again in line with projected renewable energy deployment. 2040 Compliance Pathway Begins JANUARY 2040 New, stricter emissions limits are place on covered buildings for calendar years 2040-2049 2050 Zero Emissions Requirements JANUARY 2050 All covered buildings must demonstrate compliance with an emissions factor of 0.00 beginning in 2050. Copyright 2024 Tango. All rights reserved. The law assigns a "carbon coefficient" to specify the carbon content for each fuel type. A building's annual emissions are determined by combining total energy use for each fuel type multiplied by its corresponding carbon coefficient. The carbon from electricity use by buildings will go down over time as the grid gets cleaner. Local Law 97's electricity carbon coefficient for the 2030 compliance period is about 50% cleaner than the one assigned for 2024, and aligns with New York State's ambitious mandates for renewable energy deployment.
