We draw on innovation to improve our environmental performance and to offer increasingly green mobility solutions. One of our priorities is to become a major proponent of sustainable cities, working hand in hand with local elected officials, authorities and passengers. This means balancing operational, financial, and environmental performance.

“We’re delighted to be working with RATP Dev to deliver greener buses for this city. They will help improve air quality and offer a better journey experience for customers. This is a momentous time as we help deliver the Mayor’s vision for cleaner, safer transport network.”

Transport for London’s Managing Director, Surface Transport (2011-2017)

Demographic growth, urbanization, and expanding metropolises or even megalopolises create new needs. Every day increasing numbers of passengers have to get from A to B, with the challenge of mitigating the impact on air quality and health. This requires fast, reliable transport coupled with a practical, comfortable passenger experience.

The challenge is twofold. At a global level, we're working on energy transition, and locally we're offering cities cleaner, more pleasant and tailored public transport services.

Mass transit is the only form of transportation that can meet both these challenges. A subway or tram trip produces carbon emissions fifty times lower than the equivalent car trip. Just one of Paris' express suburban lines, the RER A, transports 1.2 million people every day. That's the equivalent of a sixty-lane highway.

Reducing noise, disturbance, and pollution - RATP Group is taking action today for the city of tomorrow. Our Bus 2025 plan is aiming to make the Paris region's fleet of 4,600 buses 100% clean – i.e. 80% electric and 20% biogas – by 2025. It will be a true feat and a world first.

All modes of transport are considered in our sustainable and integrated mobility strategy. This means reducing the environmental impact of our activities and anticipating future needs and uses. Resulting innovations run the gamut from quiet, ultra-low emission trams, power-recycling train brakes, and green materials to low-energy stations, electric shuttles, or buses. Each and every one reflects our commitment to sustainable development. 

Our commitment does not focus solely on technology. As a player in all types of mobility, RATP Dev is acutely aware of its role in communities. For example, we combat waste of resources through recycling, sending unclaimed lost & found items to charities, promoting energy-efficient driving habits, and recovering of waterwaste generated from cleaning vehicles.


To provide an alternative or complementary solution to private vehicles, we are committed to rolling out and operating accessible transportation systems for the benefit of passengers and local authorities alike. To make public transport not just an option but a deliberate choice.


We are also committed to integrating transportation infrastructure into the urban fabric. Expanding and modernizing routes underpins the development of current and future cities. Leading to cities that are designed with intermodal transportation in mind so that people can move about freely.


RATP Dev has developed Europe's first fully electric vehicle for transporting up to 9 people with reduced mobility, in partnership with Gruau. Improved comfort for passengers and less impact on the environment - that's what we call a win-win solution!
Gas produced from fermenting organic waste derived from agriculture, industry, and other sources. Not only does biogas put waste to good use, but it also offers longer driving times than electric batteries.
Combining several means of transportation in one trip. An efficient intermodal network facilitates the shifting from one mode to the other (hub, integrated ticketing, unified customer information...)
Urban agriculture
Raising crops and/or small farm animals in cities. It preserves biodiversity, upcycles waste and (re)creates pleasant green areas like shared gardens, beehives, chicken coops and vines.
