By "lower emissions" I mean investing money into energy sources that don't emit CO2, into better insulation for houses, into low carbon modes of transport. This will naturally lead to less energy use, because thermal power plants are not very efficient, burning oil for heat is not very efficient (compared to a heat pump), and burning oil to move a car is not very efficient (compared to a BEV, or a train). Doing something about emissions from agriculture is a bit more difficult. Perhaps that's an area where we'll need carbon capture to reach neutrality. I do not mean moving back to a pre-industrial lifestyle.
