Carbon Footprint
The total greenhouse gas emissions caused directly and indirectly by an individual, organization, event, or product, usually expressed in metric tons of CO₂ equivalent (tCO₂e).
Why It Matters
The average U.S. household's energy carbon footprint is 7.5 tCO₂e/year through electricity and heating. Solar can eliminate 3-5 tons; electrification can address most of the rest.
