Your home emits CO2 when you use gas to heat it. That’s called operational carbon emissions. Did you know that lots of CO2 was emitted just making the stuff in your walls?  Embodied carbon is the greenhouse gas (GHG) emissions associated with the manufacturing, transportation, installation, maintenance, and disposal of building and infrastructure materials. We talk to MCAN’s Better Buildings Campaign Director to find out how we can reduce the embodied carbon in our buildings. Check our showpage at massclimateactiondotorg/blog for the hot links.
