How We Calculate
We use average fuel consumption of 9.5L/100km and a CO2 emission factor of 2.31 kg/L of gasoline. Vehicle type multipliers adjust for real-world differences in fuel efficiency.
Why It Matters
Transportation accounts for ~25% of global CO2 emissions. Carpooling is one of the most effective ways individuals can reduce their personal carbon footprint immediately.
Community Impact
RideCarpooling users collectively saved over 1.2 million kg of CO2 in 2025 — equivalent to planting 57,000 trees or taking 260 cars off the road for a full year.
