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.
Ranking
Household footprint accounting puts heating, transport and diet far ahead of everything people usually think about.

Tools
They have been evaluated. Their value is educational rather than accounting — the uncertainty is very large.
Diets, drugs, behaviour and maintenance — ranked by the strength of the evidence behind them.
Coeliac disease news, guidelines and research — plus the practical business of eating.
Electric cars reviewed on real range, charging behaviour and life-cycle emissions.
Health, science and self-improvement books fact-checked against the literature they cite.
