How to Calculate Remote Work CO₂ Savings

Remote work eliminates commutes — the single largest source of employee-related CO₂ for most SMEs. This tool quantifies those savings using EPA 2025 average vehicle emission factors. Enter your headcount and average commute distance, and get an annual CO₂ savings estimate in tonnes — instantly, with no data leaving your device.

  1. Enter the number of remote employees

    Input how many employees work remotely full-time. For hybrid policies, enter the full-time equivalent (e.g. 50 employees working 3 days remote = ~30 FTE remote).

  2. Enter the average round-trip commute distance

    Enter the average daily round-trip commute in miles. You can get this from an employee survey or use a regional average (US avg ≈ 27 miles/day roundtrip per BTS 2024 data).

  3. View your annual CO₂ savings

    The tool calculates savings using EPA's 0.393 kg CO₂/mile factor over 245 working days per year. The equivalent number of trees planted is shown alongside for stakeholder communications.

FAQ

What emission factor is used?
The tool uses EPA 2025 average emissions for a mid-size passenger vehicle: 0.393 kg CO₂ per mile. Switch to the Regional data source to use locally calibrated factors for EU, UK, or Japan if available.
How many working days per year does the calculation assume?
245 days per year (EPA US baseline, accounting for weekends and public holidays). This is a standard figure used in corporate carbon accounting.
Does this account for electric vehicle commutes?
No — the global factor does not distinguish vehicle type. EV commutes have lower tailpipe emissions but still have upstream electricity generation emissions. For precise EV accounting, use the regional factor with your local grid carbon intensity.
Can I use hybrid work arrangements in the calculation?
Yes. Convert your hybrid policy to a full-time equivalent: if 80 employees work remote 3 days per 5-day week, enter 80 × (3/5) = 48 as your employee count. The tool does not require a specific work schedule — any headcount input is accepted.
