About us

Hello! We are Paul (L) and Nico (R), and we are concerned about the relaxation of CO₂ emissions policies. With our free Petrollo app, we literally and figuratively put drivers back in the driver’s seat, empowering them to reduce CO₂ emissions while driving.

Worldwide, around 1 billion cars still run on fossil fuels. We believe that significant gains can be achieved today with a simple adjustment to driving behavior: letting your car coast more often, possibly in neutral. The Petrollo app shows you how much CO₂ emissions and fuel costs you save by doing this. That’s motivating!

Up to 40% savings in urban areas
Coasting turns out to be especially effective in built-up areas. Savings of up to 40% are achievable. The technique is simple: it makes use of the car’s kinetic energy. When approaching a traffic light, roundabout, or bend, take your foot off the accelerator as early as possible and let the car coast. Just like riding a kick scooter in the past—after pushing off a few times, you could glide along smoothly.

It not only reduces CO₂ emissions and lowers fuel costs, but also promotes more conscious and alert driving. You pay closer attention to the traffic in front of and behind you.

The message is clear: taking your foot off the accelerator is better for all of us. Less CO₂ and better for your wallet.
