What do we do?
Decarbonisation
TMB contributes to a sustainable city model through its multimodal transport offer and the decarbonisation of its activity. 59% of journeys in TMB's area of influence are made on the transport network operated by TMB in Barcelona.
Climate change and sustainability
Every day, TMB works to promote sustainability in the cities in which it operates.
How?
By utilising groundwater from the metro to irrigate the city's parks and gardens or for other uses.
We make 25% of the total groundwater in the metro network available to the public authorities: 72.47 litres/second, equivalent to the water consumed by 60,000 people in Barcelona every day.
By reducing the water consumed by transport facilities
From 2017 to 2021 we managed to reduce water consumption by 10%. From every 10 litres we use when washing buses and metros, we reuse 8 litres.
By reducing energy consumption by incorporating innovative technologies
Between 2017 and 2021, this consumption was reduced by more than 36 million kWh, equivalent to the energy consumed by 4,500 homes over an entire year.
By environmentalising material, fleet, product and service procurement
By defining and incorporating environmental criteria into the purchasing process
By carrying out awareness-raising, training and communication campaigns
Within the company and externally
By optimising waste production and management
We separate more than 65 types of waste. From 2017 to 2021, we reduced the amount of waste generated by 16%.
By implementing an Environmental and Energy Management System based on the ISO 14001 and ISO 50001 standards
For the ongoing improvement of the organisation's environmental and energy performance and as a guarantee of compliance with environmental regulations, undergoing an annual internal and external audit.
