3. Local Laws Overview

Climate Leadership and Community Protection Act (CLCPA), 2019

The CLCPA sets statewide climate targets and directs regulatory actions to reduce greenhouse gas emissions across sectors. It influences financing by shaping the cost of capital, risk assessments, and eligibility for public funding and incentives. The act remains central to how NYC businesses plan large capital projects and investor-facing disclosures.

New York State's CLCPA requires a path to an 85 percent reduction in greenhouse gas emissions by 2050 and a 40 percent reduction by 2030.

Local Law 97 of 2019 (LL97) - NYC Building Emissions

Compliance is phased with increasing stringency, starting in the mid-2020s, and affects capital planning, auditing, and potential penalties for non-compliance. Landlords, property owners, and developers often seek financing solutions that support these upgrades.

Local Law 97 places a binding emissions limit on large buildings in NYC with compliance starting in 2024 and tightening through 2030.
