Estimate your annual CO₂e from home energy, transport, flights, and diet. See a clear breakdown and practical equivalents for reduction planning.
Personal CO₂e Footprint Estimator with Category Breakdown
Enter your typical usage, choose reasonable factors, and get an annual footprint estimate in kg and tonnes of CO₂e.
Home emissions are estimated from electricity, natural gas, LPG, water, and waste. If you do not know a number, start with a rough estimate and refine it later from bills.
Travel emissions are estimated from driving, public transport, and flights. If you drive an EV, make sure your electricity factor in the Home tab is reasonable because EV emissions depend on the grid.
Food and lifestyle is estimated using a practical diet baseline plus simple adjustments for food waste, dining out, and shopping level. This section is intentionally approximate for planning.
Summary recalculates all sections using the current inputs. If a section is blank, it contributes 0 for that category.
