CO₂RESPONSIBLE MADRID is an initiative of Tourism of the Madrid City Council, funded by the European Union’s NextGenerationEU programme. Its goal is to reduce the carbon footprint generated by tourism activity in the city, working together towards a more sustainable tourism model.

It’s a way of understanding tourism as a shared experience, where everyone—visitors, businesses and the city—takes responsibility for caring for the planet while still enjoying all that it has to offer.

The programme includes the following actions:

• Campaigns to improve air quality by encouraging the use of low-emission transport.

• A calculator that allows you to measure and offset the carbon footprint of your trip through tree planting.

• A rigorous system of audits and certifications aimed at reducing emissions generated by the city’s tourism estab-lishments.

At CO₂RESPONSIBLE MADRID we want your visit to be a more sustainable, responsible and mindful experience, while still enjoying everything our city has to offer.

It’s very simple. You just need to enter a few details about your trip:

• • City of origin

• • Mode of transport used (plane, train, car, bus, etc.)

• • Number of travellers

The calculator will then provide you with an estimate of the emissions generated, based on the GHG Protocol (the most widely recognised international standard) and official data from Spain’s Ministry for Ecological Transition and the Demographic Challenge (MITECO).

Offsetting your carbon footprint means balancing the emissions generated by your trip through a positive, voluntary and verified action. Once your emissions are calculated, you can purchase CO₂ credits to offset them.

The value of these credits is fully allocated to offsetting projects in Spain, focused on forest restoration with native species and guided by rigorous technical criteria. In this way, your contribution directly helps capture the same amount of CO₂ produced by your trip.

At CO₂RESPONSIBLE MADRID, we offer three offsetting projects for you to choose from, allowing you to decide which initiative your contribution supports. You can find detailed information about each of these projects on our website.

CO₂RESPONSIBLE MADRID is an initiative of Madrid City Council’s Tourism Department, carried out with full transparency and rigour. Carbon footprint calculations follow the international GHG Protocol methodology, and all contributions go directly towards projects accredited by Spain’s Ministry for Ecological Transition and the Demographic Challenge (MITECO).

Your offset is managed through a secure, certified platform. Once the process is complete, you will receive an official digital certificate (in Spanish and English) confirming that your contribution has been allocated to your chosen environmental project.

The projects are selected through a rigorous process aligned with the EU DNSH principle (Do No Significant Harm), which ensures that every action is both respectful and sustainable. This means the projects:

• • Use native species adapted to the local environment.

• • Avoid monocultures and water-intensive plantations.

• • Ensure long-term positive impact (with at least 10 years of monitoring).

• • Support biodiversity conservation and ecosystem restoration.

In addition, compliance with DNSH and all technical requirements is verified by an independent external auditor, accredited under ISO 14065 for EU ETS verification, before the projects are selected.

In short, CO₂RESPONSIBLE MADRID complies with all the necessary guidelines and standards, allowing you to take meaningful environmental action.

Every action matters. By calculating and offsetting your carbon footprint, you show your commitment in a tangible way and play an active role in the shift towards more environmentally responsible tourism.

Not only does your contribution reduce the impact of your trip but sharing your certificate can also inspire other travellers to join in protecting the environment. Together, we are all “CO₂RESPONSIBLE”.
