It is a campaign to raise awareness and encourage good practices in the use and consumption of water and energy. The financial savings achieved are then used to fight the climate emergency.

Why are we doing the Marathon?

Because we believe that it is very important for everybody that uses or works in municipal buildings and facilities to be aware of the energy, water and heating they consume and of the impact their actions have on climate change.

By paying more attention to how we consume energy, we will see how we can really reduce our footprint through small, everyday actions.

This action also aims to highlight the need to address the climate emergency

we are facing. Water and energy are finite resources and using them unnecessarily has serious consequences for the entire planet. Sorting waste properly and reducing energy consumption help mitigate the effects of climate change.

How does the Marathon work?

Various municipal buildings and facilities around all the city's districts take part in the Marathon throughout the month of February. This means that the people who work in these buildings or use their facilities must pay extra attention to their water and energy consumption, and reduce or recycle the waste they produce.

Water, electricity, gas consumption and CO2 emissions are monitored on a weekly basis to see whether consumption levels have managed to be reduced compared to previous years.

The resulting savings are converted into an amount of money to be spent on projects to combat the climate emergency.

Marathon 2020

A total of seventy-two facilities took part in the 2020 Marathon, which led to  a saving of 309,680 kWh of electricity, a 9.34% reduction, and 1,603,750 kWh of gas, a 27.14% reduction. Regarding water, 6,362 m3of water was saved, a 10.39% reduction. These figures mean a reduction in CO2 emissions of 33,259.63 kg CO2eq saved in electricity and 325,561.25 kg CO2eq saved in natural gas.

All of these savings represent a monetary amount of €106,501. The savings made by sports facilities and schools will mainly be used to improve these same facilities. The remainder will be used towards  a project to create social cultivation areas on the rooftops of municipal buildings, run by non-profit organisations. This initiative makes use of unused rooftops of municipal buildings to create cultivation patches tended to by people with disabilities.
