Frequently Asked Questions

Why ranking matters?
Many feel-good actions (reusable bag, turn off lights) save 0.01-0.05 tonnes/yr. Skipping one transatlantic flight saves 1.5-3 tonnes. 100× difference. Ranking helps focus on what actually moves the needle.
Source of CO2 data?
IPCC AR6, UK DEFRA conversion factors, Our World in Data, Project Drawdown. Ranges vary — values are mid-range estimates. Goal: order-of-magnitude awareness, not precision.
What about systemic vs individual?
Both matter. Individual CO2 is ~30% of total emissions; rest is systemic (industry, energy mix). But individual choices DO matter (especially diet, flying), and they signal demand → systemic change follows.
