Get on the tram and help to improve the environment

With the ecoCalculator we show you that, using TRAM, you are helping to improve the environment of Barcelona and its metropolitan area. Choose your route and you will see that the tram is one of the most modern and sustainable public transport.

TRAM contributes to the fight against climate change

Any vehicle with combustion engine emits CO2, which is the main pollutant gas responsible of climate change. Being a 100% electric vehicle traction, TRAM is a transport system that does not generate direct emissions in urban areas; only generated in the power plant that produces the energy used.

1 tram

carrying 30 people on average:

50,283 gr CO2/km and user

1 vehicle

carrying 1,6 people on average:

122,62 gr CO2/km and user

TRAM contaminates less

Any vehicle with combustion engine emits NOx and particulate matter (PM10), which are the main contaminants directly affect health. Being a vehicle with 100% electric traction, TRAM contributes to improving the quality of life of people.

0,034 g NOx/km and user

0 g PM10/km and user


carrying 1,6 people on average:

0.034 g NOx/km and user

0 g PM10/km and user

To get an idea of what is the pollution in Barcelona and its metropolitan area, who have a data: citizens breathe 292kg of suspended particulate (PM10) every year.

TRAM saves energy

The technology that equips the entire TRAM network makes its energy consumption very efficient; in addition, during braking the engines of a tram generate electricity that take advantage of other trams.
