Colorado's statewide law targets Greenhouse Gas Emissions (GHG) reduction, not just energy use. It mandates a 7% reduction by 2026 and 20% by 2030 (vs 2021 baseline).

Denver adopted the Energize Denver Ordinance in 2021 to transition from annual benchmarking to mandatory efficiency targets, directly supporting the city's goal of Net Zero emissions by 2040.

Passed in March 2025, this law is the first BPS in Illinois. It mandates that covered buildings eliminate on-site emissions (gas combustion) and procure 100% renewable electricity by 2050, supporting Evanston's Climate Action Plan (CARP).

Maryland's statewide BEPS focuses heavily on Direct GHG Emissions (burning fossil fuels on-site). While Energy Use Intensity (EUI) targets will be added in 2027, the primary mandate is to eliminate on-site combustion by 2040.

To achieve the county's aggressive goal of Net Zero Emissions by 2035, this law establishes long-term energy efficiency standards, requiring buildings to improve their own specific baseline performance over 5-year cycles.

Local Law 97 is the "Gold Standard" of building emissions laws. It places strict Carbon Caps on buildings starting in 2024. The limits tighten drastically in 2030, aiming to reduce citywide emissions by 40% by 2030 and 80% by 2050.

Newton's BERDO mirrors Boston's law but with a key difference: it focuses primarily on Direct Emissions (fossil fuels burned on-site) because the state grid is cleaning up electricity. It targets ~300 large buildings responsible for 23% of city emissions.

Oregon's BPS is based on ASHRAE Standard 100. Uniquely, Multifamily, Schools, and Hospitals are currently "Tier 2," meaning they must report data but do not yet have mandatory performance reduction targets (unlike Commercial Tier 1).

Unlike NYC or Boston, Philadelphia's BEPP is a Prescriptive law. It does not set a hard carbon cap yet, though Philadelphia aims for net zero carbon emissions by 2050. Instead, it mandates a "Tune-Up" every 5 years to identify and fix operational inefficiencies (e.g., broken sensors, leaks, scheduling errors).

Reno's EWEP is a "Performance-Triggered" law. While annual benchmarking is mandatory for everyone, buildings that perform poorly (below standards) are triggered into a mandatory "Performance Phase" requiring an audit and action plan.

St. Louis set aggressive targets requiring buildings to hit specific Site EUI numbers by May 2025. The goal is to bring the bottom 65% of buildings up to the efficiency of the top 35%, ratcheting down every 4 years toward carbon neutrality.

San Francisco focuses on Transparency (Audits) and Grid Decarbonization (Renewable Power). While it doesn't yet have a "Carbon Fine" like NYC, it mandates that large commercial buildings switch to 100% renewable electricity by 2030 to eliminate Scope 2 emissions.

San Jose's BPO goes "Beyond Benchmarking" by requiring buildings to prove efficiency or improve it. It supports the Climate Smart San José plan to reach carbon neutrality by 2030, one of the most aggressive city goals in the US.

Seattle BEPS works in tandem with Washington State law but targets Greenhouse Gas Intensity (GHGI) rather than just energy efficiency. Its goal is to fully decarbonize the city's building sector by 2050.

The "Clean Buildings Act" is a statewide mandate focusing on Energy Efficiency (lowering usage), not just carbon. It requires an Energy Management Plan (EMP) and Operations & Maintenance (O&M) program for all covered buildings.

DC BEPS is one of the most aggressive laws in the nation. If a building falls below the median ENERGY STAR score for its type, it enters a "Compliance Cycle" and must reduce energy use by 20% or reach the standard.
