For the average American, 4 devices in their home - water heaters, furnaces, stoves and gas powered clothes driers - account 95% of residential emissions [1]. Residential energy use accounts for ~20% of US annual carbon emissions [2].

The 2nd figure accounts for carbon footprint of electricity generation used in the home as well as gas combusted in the home. The 4th chart from [1] suggests this is about a 50/50 split (if we bring grid emissions to 0 but don’t exchange these natural gas devices, carbon intensity remains at half of what it is today). Therefore, we can conclude that these 4 appliances in residential properties account for 10% of US carbon footprint.

You could potentially make an argument that stoves are not the lions share of those emissions - but even if they only represent 10% of residential building emissions, that’s still 1% of US carbon emissions annually (which is a huge number when expressed in tons of CO2)
