The ordering problem
Recycling, turning off lights and avoiding plastic bags dominate the public conversation and are among the smallest levers available. Heating, flying, driving and diet dominate an actual household footprint. The gap between what people do and what matters is the single most useful thing this site can point at.
Food

Dietary shift has real, measurable effects — and the variation within a food category can exceed the variation between categories.
Aviation
Flying and non-CO₂ effects

Tools
