Electricity, driving, and flying — one estimate.
For most people, home electricity, car travel, and air travel make up the majority of their personal carbon footprint — this calculator applies typical emission factors (kg CO₂ per kWh, per mile, per flight hour) to each.
Actual emissions vary by local electricity grid mix, vehicle efficiency, and flight class — this gives a useful order-of-magnitude estimate for comparing choices (like driving vs. flying) rather than a precise personal audit.
