Starting next month, New York City building owners will gain a new compliance option under the city's ambitious building decarbonization law, Local Law 97. They can purchase renewable energy credits tied to Canadian hydropower, a move that could reshape how the real estate sector meets emissions targets.
The program allows building owners to buy credits from an existing hydropower facility, effectively counting the clean energy generation toward their own mandated emissions reductions. However, critics argue the credits may not represent additional carbon cuts — the hydropower plant was already operating — and could delay necessary investments in on-site electrification or efficiency upgrades.
The scheme's financial details remain undefined, but it introduces a potentially lower-cost compliance pathway for the city's roughly 50,000 covered buildings. Proponents say it accelerates renewable energy financing while giving owners flexibility, though skeptics warn it could undermine the law's intent to drive direct building retrofits.
Geopolitically, the credits rely on power imported from Quebec, tying New York's climate policy to cross-border energy trade. The approach aligns with broader regional efforts to integrate renewables, but raises questions about counting hydropower — often controversial due to its environmental impacts — as a clean energy solution.
Real estate groups welcome the flexibility, but environmental justice advocates caution that credits could become a loophole. Without stringent verification, they warn, the city might claim emissions reductions on paper that don't materialize in the air.
