Local Law 97, answered

What is building decarbonisation?

Reducing a building's carbon emissions through energy-efficiency upgrades, electrification and clean energy. In NYC, buildings account for roughly 70% of total carbon emissions — so the building stock is where the largest reductions are won.

What is Local Law 97?

NYC's landmark climate law sets carbon-emission caps for most buildings over 25,000 ft², tightening in 2024 and again in 2030. Owners over their cap pay a penalty of $268 per metric ton of CO₂e per year.

How can I avoid LL97 fines?

Get a baseline carbon assessment, then prioritise the measures with the best return: efficiency upgrades, electrification of heating, and on-site or procured renewables. RUHLai builds the roadmap that keeps you under the cap at the lowest cost.

Are there incentives to offset the cost?

Yes. Incentive programs can offset up to 50% of project cost depending on the measures, and we factor available incentives into every roadmap.

How much can smart-building technology save?

Controls, sub-metering and a building-management system typically cut energy use a further 10–25% on top of equipment upgrades — often among the fastest-payback measures.

What energy savings are typical?

A well-designed decarbonisation project commonly delivers 20–40% energy-cost savings while raising the asset's market value through improved sustainability performance.
