Explore CarbonRoute

We use Istanbul-specific emission factors sourced from doctoral research at Marmara University — not generic global averages. For every route, CarbonRoute multiplies the distance traveled on each transport mode by its real per-passenger emission rate, giving you an accurate kilogram-by-kilogram view of your impact compared to driving.

Yes — CarbonRoute covers Istanbul's full public transit network. That includes 795 IETT bus routes, every metro and tram line, the metrobüs, Bosphorus and Islands ferries, trains, and minibuses (dolmuş). Walking distances between transfers are also factored in.

Every trip you take with CarbonRoute is automatically logged. Open your profile to see daily, weekly, and monthly breakdowns of how many kilograms of CO₂ you've saved versus driving the same routes — visualized with clean charts and milestone badges.

CarbonRoute is currently Android-only as part of its initial development phase. iOS support is on our roadmap for future releases — sign up for our beta to be the first to know when it launches.

Yes — CarbonRoute supports private car routes alongside public transit, walking, and cycling. While we don't encourage driving (that would defeat our mission 🌱), we believe in transparency: seeing your car route's CO₂ impact next to greener alternatives is the best way to make a conscious choice. Sometimes the lesson is the comparison itself.

Only what's needed to make the app work — your location during active trips, your route history for impact tracking, and basic profile info if you create an account. We never sell your data, never share it for advertising, and you can delete everything from settings any time.
