Commute time & CO₂ calculator with AI insights.
How much commute time, CO₂ and money do your employees save through more home office? Answer in 30 seconds — with ready-to-use statements for your careers page, LinkedIn and ESG report.
Commute time & CO₂ calculator
Basis: 46 working weeks/year, UBA TREMOD 2023 (CO₂), ADAC car cost (€0.30/km), transit ticket €0.12/km, beech tree absorbs ~22 kg CO₂/year.
Why commute time is the most underrated recruiting argument
An average German full-time employee commutes 17 km one-way — roughly 70 minutes of life-time per day that is neither paid nor valued. Over a year that's more than 250 hours nobody gets back. Employers offering two extra home-office days per week give every team member several full weeks of life-time per year. That's not a benefit — that's a statement.
What you can do with the results
Methodology
CO₂ factors are based on TREMOD 2023 (UBA) and reflect the average German car fleet plus the public-transit mix of bus, tram, S-Bahn and regional rail. Car cost of €0.30/km follows the ADAC cost calculator for the compact class (fuel, wear, proportional depreciation). Particulate values include both exhaust and abrasion (tires, brakes). A tree absorbs around 22 kg CO₂ per year — we use a mid-aged beech as reference.
How AI insights work
After the calculation, our AI translates the raw numbers into communicable statements: a sharp headline, three ready-to-use LinkedIn/careers statements with concrete figures, an ESG sentence for your sustainability report and a human angle on the reclaimed life-time. A spreadsheet becomes a story that resonates with candidates, employees and stakeholders.
FAQ
How accurate are the CO₂ savings?
We use the official TREMOD 2023 factors from the German Environment Agency (UBA): 154 g CO₂/km for the average car, 58 g CO₂/km for public transit (bus, tram, S-Bahn, regional rail mix). Bike and walking are zero. This delivers realistic numbers fit for ESG reports and employer branding.
How is commute time calculated?
We use realistic door-to-door speeds: 30 km/h car (incl. traffic and parking), 25 km/h transit (incl. transfers and waiting), 12 km/h bike/walk. Multiplied by round-trip and 46 working weeks per year.
Why 46 working weeks?
52 weeks minus 6 weeks for holiday and sickness equals 46 productive working weeks per year – the standard for workforce planning.
What's included in the mobility cost?
Car: €0.30/km per ADAC cost calculator (fuel, wear, depreciation share). Transit: €0.12/km as a blend of monthly/annual passes and singles. Bike/walk: €0. This money flows straight out of your employees' pockets – a concrete recruiting argument.
