Methodology

Combustion emissions: 164 g CO2/km (petrol), 148 g CO2/km (diesel) - 2024 EU fleet average. Well-to-wheel multiplier: x1.2 (extraction, refining, transport).

BEV emissions (grid): 42 g CO2/km - the Polish generation mix at ~550 g CO2/kWh (URE 2025), 17.4 kWh/100 km consumption. With PV: 5 g CO2/km (panel lifecycle).

Equivalents: 1 tree absorbs ~22 kg CO2/year (IPCC). WAW→BCN flight: ~340 kg CO2 (ICAO Carbon Emissions Calculator).
