Why do building emissions matter?
Why do building emissions matter?
Heating, hot water, and cooking from onsite combustion of fossil fuels (natural gas, oil, and propane) in buildings is the biggest source of Greenhouse Gas emissions in Lexington.
Electrifying our homes and commercial buildings is essential in reaching our Net Zero emission goals by 2035.

✓ Article 31 BEU-D (Building Energy Use Disclosure) (passed 2022 All Town Meeting, pending AGO approval) requires all buildings over 25K sq ft to report their gas and electricity use annually so that the town can report annually on building green house gas emission intensity.
Town legislation next steps under consideration:
Town legislation next steps under consideration:
! Advocate for and adopt the state's Net Zero Specialized Stretch Energy Code (aiming December 2022)
