STUDY – Carpooling saves more than 1.6 million tonnes of CO2 a year, whilst doubling the number of people traveling

BlaBlaCar today announces the release of Zero Empty Seats, a global study into the environmental impact of carpooling. The report, conducted with French research institute, Le BIPE, is the first study based on real usage data from BlaBlaCar’s community of 70 million carpoolers.

Paris – 27 Mar 2019

The study, which follows BlaBlaCar’s recent research into the social impact of its activity, reveals the current and projected CO2 savings generated by carpooling.

Le BIPE, a member of the BDO Group, looked at BlaBlaCar’s real usage data over 12 months and surveyed 6,884 BlaBlaCar members across 8 countries.

The results show that BlaBlaCar doubles the number of people traveling whilst operating a carbon-saving network.

In total, 1.6 million tonnes of CO2 were saved by BlaBlaCar carpoolers in 2018, thanks to the relative efficiency of filled cars versus alternative modes of transport, members’ improved driving behaviors whilst carpooling, and the informal carpooling inspired by BlaBlaCar outside the platform.

Key findings

  • Total CO2 savings: 1.6 million tonnes of CO2 saved by carpooling in 2018 – equal to the CO2 emitted in a year by road traffic in Paris.
  • 3.9 people per car: the average car occupancy rate on BlaBlaCar (vs 1.9 people per car without BlaBlaCar).
  • With only 1.6% more cars on the road, carpooling enables the transport of two times the number of passengers in cars (+210%), whilst reducing CO2 emissions by 29%
  • Changing behaviors:
    • Driving license: 28% of BlaBlaCar passengers who don’t yet have a driving license are delaying their driving test thanks to carpooling
    • Road safety: 22% of BlaBlaCar drivers reduce their speed when carpooling, further increasing the CO2 savings generated by BlaBlaCar
  • What about buses? With a 60% average occupancy rate, a bus emits even less CO2 per passenger kilometer than carpooling (36 grams of CO2 per passenger kilometer, vs 58g per passenger kilometer for carpooling). This mode of transport will make an important contribution to the future of BlaBlaCar’s carbon-saving network.
The facts are simple – to protect the future of our environment, we must work together to take action today. These results show how carpooling and shared mobility can significantly lower the carbon footprint of transport, without limiting travel aspirations or access to mobility. BlaBlaCar has always fought to reduce the number of empty seats on the road, and the ongoing roll-out of long-distance buses on our platform will further reinforce our efforts in that direction.

The bigger picture: what solutions for more CO2 savings?

Today, 75-80% of long-distance travel in Europe is done by car, but with an average occupancy rate of only 1.9 people, most cars still have at least three seats left empty.

Shared mobility has a bright future – but how can BlaBlaCar go further to reduce the carbon footprint of road travel?

The Zero Empty Seats report presents four different scenarios based on ongoing innovations and BlaBlaCar community growth forecasts. From scaling carpooling for commuting to delivering a door-to-door travel experience, multiple levers exist to help save an annual total of 6.4 million tonnes of CO2 in 2023.
