Carbon Footprint (Trip) Calculator
Estimate CO₂ emissions from trips: car (gasoline, ethanol, diesel, electric), plane, bus. Inputs: distance and mode.
Carbon footprint of personal activities
A carbon footprint measures greenhouse gas emissions from a person, product or activity in kg or tonnes of CO₂-equivalent (CO₂e). The simplified formula is emissions = activity × emission_factor. Reference factors: gasoline car ~0.17 kg CO₂e/km, commercial flight ~0.11 kg/km/passenger, electricity = kWh × grid intensity (Brazil ~0.09, US ~0.4, China ~0.6 kg/kWh), beef ~27 kg CO₂e/kg vs vegetables 0.5-2 kg. Example: 500 km by gasoline car → 500 × 0.17 = 85 kg CO₂e. The global average per capita footprint is ~4.5 t/year; Brazil ~2 t (low thanks to a hydroelectric-dominated grid), United States ~16 t, China ~7 t. The GHG Protocol classifies emissions as Scope 1 (direct), Scope 2 (purchased energy) and Scope 3 (value chain).
Applications
ESG and corporate sustainability reporting (CSRD in the EU from 2024), voluntary carbon offsetting, transport decisions (plane vs train vs car), regenerative business strategy, ANTT inventories for road freight in Brazil, individual lifestyle audits.
FAQ
Why CO₂-equivalent and not just CO₂? Because methane, N₂O and fluorinated gases have higher warming potential per kilogram. CO₂e normalises everything to the warming impact of one kg of CO₂ over 100 years (GWP-100).
Is electric car always cleaner? Depends on the grid. In Brazil yes (clean hydro mix); in coal-heavy grids the lifecycle footprint can be similar to a hybrid in the first years.
How does flying compare to driving? Per passenger-km a full economy flight is roughly equivalent to a single-occupant gasoline car, but the absolute distance flown is usually far greater.

Estimate your car annual carbon footprint from the distance driven and the average fuel consumption. Find out how much CO₂ you emit each year by driving.
CO₂ Volume Produced
Calculate the CO₂ volume produced in complete combustion of a hydrocarbon C_xH_y, V_CO₂ = x × 22.4 ÷ M, from the number of carbon atoms x and the fuel molar mass M (g/mol). The result, in Nm³ of CO₂ per kg of fuel, is the carbon dioxide generated by complete burning — information for emission inventories, exhaust system sizing and gas analysis. Each carbon atom in the fuel becomes one CO₂ molecule. Methane produces ~1.4 Nm³/kg. Fuels with more carbon per unit mass (coal, heavy oils) produce more CO₂. Enter x and the fuel molar mass.
Plane Flight Carbon Footprint

Energy per Elevator Trip
Calculate the potential energy spent to raise a load, E = m·g·h, from the unbalanced mass m (net load after the counterweight, kg), gravity g and the lift height h (m). The result, in joules, is the minimum theoretical energy to hoist the load — a basis for estimating the elevator's electrical consumption and the energy-regeneration potential. Modern elevators with regenerative drives recover part of this energy on descent (when the counterweight descends with a light car), feeding it back to the grid. Actual consumption is higher, divided by the efficiency. Enter the unbalanced mass and the lift height.
