We cannot assume that we are materially reducing greenhouse gas emissions just by putting heat pumps into homes at scale. Additional metrics are necessary to assure that we are benefitting the climate. Our climate report card should include those metrics.

Funding building decarbonization
I hope that the Climate Chief’s call for an economic analysis leads to a thorough review of the resources required to achieve our goals for decarbonization of existing buildings.
Energy conservation expectations
In existing homes, we are likely to have to get most of our carbon reductions by decarbonizing heating systems as opposed to improving building envelopes.
Building envelope improvements
Non-envelope improvements — electrification, burner efficiency, behavior changes — account for the majority of the observed decline in residential fossil energy use intensity before 2009.
Behavior changes
An approximately 8 degree reduction in thermostat settings since the 1970s saves approximately 26% off our home space heating consumption.
Israel
No words can adequately condemn the actions of Hamas over the past few days.
