Karbo detects how you move and calculates your carbon footprint automatically. No manual logging. Just live your day and watch your impact.
Three layers of detection working together so you never have to open the app to log a trip.
Karbo reads your movement patterns, speed, and the roads you take. Walking at 5 km/h on a sidewalk? Driving at 90 km/h on the A7? It knows the difference.
Connected to your car's Bluetooth? Plugged into the charger? Karbo picks up on these signals to confirm vehicle type and even detect carpooling through nearby phones.
Sync with OuiSNCF, Strava, VLib, and more. When you book a train or log a ride, Karbo pulls verified trip data for perfect accuracy.
Not another calculator that guilt-trips you. Karbo gives you a daily budget, tracks it passively, and shows you where the wins are.
Like a step counter for CO2. Set your daily target and watch your impact in real-time as you move through the city.
Every Sunday, see what worked. Which days you stayed under budget. Which routes saved the most carbon. Trends that matter.
Bluetooth proximity sensing detects other phones in the vehicle. Carpooling? Your per-person emissions drop automatically.
Native integrations with OuiSNCF, VLib, Velov, and local transit. Built in Lyon, designed for how France actually moves.
Karbo shows your transport carbon like Apple Health shows your steps. One number. One goal. Every day.
Karbo makes the invisible visible. No guilt. No effort. Just clarity about how you move and what it costs the planet.
