A typical UK household's gas and electricity comes to around 2.5 t CO₂e a year — about 119 tree-years. Count everything a person is responsible for (travel, food, goods and services) and the average UK per-capita footprint is closer to 11 tonnes — some 524 trees.
The home number is the one you can actually move: better fabric, a heat pump and solar all cut it, and the electricity share falls every year as the grid decarbonises.
