Regie Autonome des Transports Parisiens (RATP) is a leading French, state-owned, urban mobility company. The company operates the public transport networks in the region of Greater Paris, Île-de-France. In this region it is responsible for the continuity, quality, performance and security of public transport; it operates over 3.3 billion journeys per year through 206 km of metro lines, 117 km of regional train lines, 105 km of tram lines and 4,700 buses. In Île-de-France, RATP owns the infrastructure networks, while Île-de-France Mobilités owns the rolling stock (buses, metro, trains and trams). While operating the public transport in Île-de-France is its core activity, RATP also operates public transport networks in 13 other countries, across four continents. On a daily basis it operates eight means of public transport: metro, tram, buses, regional trains, sightseeing, maritime shuttles, cable transport and transport on demand. Through partnerships it also operates new sustainable urban mobility modes such as autonomous shuttles, electric scooters, carpooling and car sharing. RATP was founded in 1949 and has over 64,000 employees.
Public transport plays a key role to facilitate a shift in modes of transportation, which enables the transition towards a low-carbon economy and contributes to climate change mitigation and to building sustainable cities. RATP plans to eliminate its diesel-powered buses and replace it with a fleet of 4,700 electric, hybrid or bio-gas-powered buses by 2025. This green bond was issued to finance the purchase of new clean buses and the transformation of bus depots to facilitate charging these clean buses. These investments enabled savings of 143,000 tonnes of CO2 emissions per year. Other projects financed by the green bond were the redevelopment of two more energy efficient metro line maintenance workshops and the purchase of new metro trains on a metro line in Paris which are 17% more energy efficient, have reduced emissions of particles and are fully accessible for disabled people.
