How carbon footprint is calculated
Carbon footprint is measured in tonnes of CO₂ equivalent (CO₂e), which accounts for all greenhouse gases. Transport includes driving (using average emission factors by vehicle type) and flying (approximately 255g CO₂e per km). The Paris Agreement target of 2 tonnes/year per person would require major lifestyle changes from current averages.
