The law sets forth emissions regulations that require most buildings, particularly new york city's largest buildings, to reduce greenhouse gas emissions below defined thresholds by 2024 and increasingly tight emission limits by 2030.
Owners must reduce greenhouse gas emissions by carrying out energy efficiency improvements, switching to clean energy solutions, and optimizing building systems to align with compliance standards.
For building owners, the path to compliance is complex, with variable emissions limits depending on building type and occupancy.
Achieving compliance requires major performance upgrades, precise reporting, and alignment with regulatory and sustainability partners including DOB and NYSERDA.
How Henson Architecture Integrates Preservation With Compliance

Established in 2003, Henson Architecture combines its heritage preservation ethos with top-tier sustainable design to help buildings hit emission benchmarks while maintaining identity.
Adapting heritage buildings to fit within carbon emission regulations is a nuanced challenge.
The mix of old infrastructure and sensitive design in these structures often calls for precise, knowledgeable handling to avoid undermining architectural value.
Henson Architecture’s team is adept at reconciling retrofits with design, employing building envelope consulting NYC expertise, Passive House techniques, and carbon assessments for comprehensive emission strategies.
Energy Upgrades and Reporting: The Path to Law 97 Compliance
Energy is at the core of Local Law 97’s compliance framework.
The law mandates that building owners implement meaningful energy efficiency measures to meet emissions targets.
Their collaborative process includes energy audits, comprehensive facade revamps, and envelope solutions, all focused on cutting operational energy and emissions.
Accurate data submission is pivotal for ongoing law 97 compliance success.
Year-over-year data submission to the DOB is necessary to prove alignment with Local Law 97 benchmarks.
Failure to comply can result not only in fines but in reputational and financial risk.
The firm helps owners prioritize robust reporting and addresses all DOB expectations for efficient compliance.

Their leadership in sustainability secures business continuity as new carbon laws come into force.
Why Immediate Action Matters for Owners under Law 97
New York City's ambitious climate targets reflect an urgent need to reduce urban greenhouse gas emissions significantly.
Buildings contribute almost 70% of greenhouse gas emissions in NYC, which is why they are targeted in new regulations.
By establishing emissions regulations through Local Law 97, the city has placed clear mandates that building owners must meet to contribute responsibly to climate action.
The firm understands that piecemeal upgrades aren’t enough for most buildings to comply with law 97.
Integrated services spanning preservation, energy retrofits, and clean energy unlock real sustainability progress for NYC buildings.
Their approach supports owners in reaching compliance and securing lasting value through energy savings and building preservation.
Funding and Accelerator Programs: Unlocking Opportunities for Owners
Compliance investments can be substantial.
Thankfully, NYSERDA and the NYC Accelerator offer important support and funding to help owners manage project costs.
