Your recorded driving. A transparent estimate.

Vehicle electricity

16.9 kWh/100 km: the upper end of Volkswagen’s published 2020 ID.3 Pro Performance 150 kW WLTP range, 15.4–16.9 kWh/100 km. This is a model benchmark; the exact configuration and real consumption of your car have not been measured. Weather, speed and charging conditions can change consumption.

Electricity generation

84.6 g CO₂/kWh: arithmetic average of 104,535 available five-minute DK1 observations in Energinet’s CO2Emis series for calendar year 2025, retrieved 8 September 2026. Coverage: 99.44% of 105,120 expected observations. Missing intervals were omitted, not filled with zero. Unrounded mean: 84.59534127325776.

This is a historical West Denmark grid benchmark. It is not weighted by your charging times, consumption or supplier contract. Charging location is assumed to be DK1. Network losses are not added. This near-real-time series is not a certified annual electricity declaration.

Comparison vehicle

125 g CO₂/km: Volkswagen Golf 1.5 TSI 150 hp, six-speed manual, 2020 WLTP. This is an illustrative petrol comparator, not a claim that your fleet replaced this exact car.

Calculation and scope

Electricity = reported km × 16.9 ÷ 100.
EV CO₂ = electricity × 84.6 ÷ 1,000.
Petrol CO₂ = reported km × 125 ÷ 1,000.
Estimated avoided CO₂ = petrol CO₂ − EV CO₂.

This compares electricity-generation CO₂ with petrol tailpipe CO₂. It excludes vehicle and battery production, fuel supply chains, other greenhouse gases, and network losses. Results are CO₂, not CO₂e or full life-cycle savings. Keep comparative estimates separate from a company emissions inventory. No energy cost is estimated until an electricity tariff is provided.
