Estimate your annual CO2 emissions from daily life.
The global average carbon footprint is about 4.7 tonnes of CO2 per person per year, but this varies enormously: the average American produces ~16 tonnes, while someone in India produces ~1.9 tonnes. Transportation typically accounts for 25-30% of a household's footprint, with flying being the single most carbon-intensive activity per hour. Home energy (heating, cooling, electricity) contributes 20-25%. Diet makes up 10-15%, with beef and lamb producing 20-30x more emissions per calorie than plant foods. Small changes compound: switching from driving to cycling for short trips, reducing one long-haul flight, and cutting red meat consumption by half can reduce your footprint by 2-3 tonnes annually.
