Which regulations apply to your buildings?
Steam trap performance directly affects your building's emissions intensity. Both laws impose escalating fines for non-compliance — and both reward buildings that can document reduction efforts.
Building Emissions Reduction and Disclosure Ordinance Jurisdiction: Boston, MA
BERDO 2.0
-
Applies to: Buildings 20,000 sq ft and larger
​
-
What it requires: Annual greenhouse gas emissions disclosure and compliance with declining carbon intensity limits
​
-
Limits begin: 2025, tightening every five years through 2050
​
-
End goal: Net-zero emissions by 2050
​
-
Penalty: Up to $1,000 per day for non-compliance
​
How steam traps connect: Steam system losses show up directly in your Scope 1 emissions (on-site fuel combustion). Reducing failed traps lowers your emissions intensity and keeps you on the right side of the declining limits.
-
Applies to: Buildings 25,000 sq ft and larger
​
-
Phase 1 limits: 2024–2029
​
-
Phase 2 limits: Significantly stricter starting 2030
​
-
Penalty rate: $268 per metric ton of COâ‚‚ over the building's annual cap
​
-
Potential exposure: Six-figure annual fines for large buildings that miss their cap
​​
How steam traps connect: NYC's district steam system is a major emissions source for covered buildings. Trap failures increase steam consumption, which increases your emissions factor, which increases your LL97 exposure dollar for dollar.
New York City Local Law 97 — part of the Climate Mobilization Act Jurisdiction: New York City, NY
Local Law 97 (LL97)
Calculate Your Energy Loss
Not sure how much COâ‚‚ your steam losses are generating? The EPA's Greenhouse Gas Equivalencies Calculator translates your energy waste into plain-language equivalents — like the number of cars taken off the road, or homes powered for a year. Use it to understand your emissions footprint, then bring those numbers back to STS for a remediation plan.
