New York City's Local Law 97, part of the Climate Mobilization Act, sets increasingly strict carbon emission limits for buildings over 25,000 square feet. While most of the conversation has focused on operational emissions — heating, cooling, and energy use — the law's implications for building materials are becoming impossible to ignore.
Understanding Embodied Carbon
Embodied carbon refers to the greenhouse gas emissions associated with manufacturing, transporting, and installing building materials. While Local Law 97 currently focuses primarily on operational carbon, the conversation in city government and the construction industry has shifted significantly toward embodied carbon in recent months.
The NYC Mayor's Office of Climate and Environmental Justice has signaled that future amendments to the law will likely include embodied carbon requirements. Several council members have already introduced proposals to require Environmental Product Declarations (EPDs) for major construction projects.
Why Reclaimed Lumber Matters
Reclaimed lumber has one of the lowest embodied carbon profiles of any structural building material. Unlike new timber (which requires logging, processing, and long-distance transport) or steel and concrete (which are extremely carbon-intensive to produce), reclaimed wood is essentially a recycled material with minimal processing requirements.
For developers looking to future-proof their projects against tightening regulations, specifying reclaimed lumber where possible is a practical and effective strategy.
Current Incentives
While there's no direct tax credit specifically for using reclaimed materials in NYC construction, there are several indirect benefits:
- LEED points: Reclaimed materials contribute to Materials and Resources credits in LEED certification, which can increase property values and attract environmentally conscious tenants
- NYC Green Building Incentives: Projects that exceed Local Law 97 requirements may qualify for expedited permitting and reduced fees
- Marketing value: In a market where tenants increasingly care about sustainability, reclaimed materials are a tangible, visible differentiator
How We Help Developers
New York Lumber works with developers and their architects to identify opportunities for incorporating reclaimed lumber into projects. We can provide:
- Material sourcing and specification assistance
- Documentation of material provenance for LEED submittals
- Carbon impact estimates comparing reclaimed vs. new material options
- Custom milling to meet project-specific dimensions and profiles
Local Law 97 compliance is going to get stricter over time. The developers who start incorporating low-carbon materials now will be ahead of the curve when embodied carbon requirements become mandatory.
