RATP has embarked upon environmental management initiatives in an effort to reduce its environmental impacts and control environmental risks at its sites. It is committed to obtaining ISO 14001 certification for its industrial sites by the end of 2010.

RATP is striving to reduce water consumption at all its sites. The renewal of equipment, which began some ten years ago, is generating considerable savings:

• Treatment stations recycling the water used to wash buses and trains;
• Train washing systems using rain water;
• The sites are equipped with water-saving devices such as push button flush valves and dual-flush toilets.

RATP is also reducing its use of paper and consumables.

The operation and maintenance of trains and buses generate industrial waste. This is sorted into categories (metals, wood, tyres, etc.) in accordance with environmental legislation, and recycled or reused to optimum effect. RATP is now also aiming for significant waste reduction at source.

Recycling waste
Several thousand tonnes of waste are also produced annually in stations. Since 2006, selective sorting has been in place in some parts of the network: specifically line 14 of the metro, Denfert-Rochereau station, the T3 tram line, and Bourg-la-Reine and Chessy RER stations. RATP wants to extend selective sorting across its networks in the next few years.

• 900,000 m³ of water consumed each year;
• 8.5 million m³ of seepage water in our networks each year;
• 16,000 tonnes of waste produced at our sites each year;
• 10,000 tonnes of waste produced by our passengers each year;
• More than 500 tonnes of paper consumed each year.

Tips
Help us to keep our premises clean:

• Use the bins provided to dispose of your rubbish. Rubbish on the tracks can cause fires.
• Take your newspaper with you when you leave a train, rather than leaving it behind.
• Report any cleanliness issues on the network to RATP staff so that they can be quickly remedied.
• Sort your rubbish by putting your recyclable waste in the yellow bins.
