The city of Madrid consolidates itself among the most advanced cities in environmental policy by renewing, for the fourth consecutive year, the A rating in the Carbon Disclosure Project (CDP).
In 2025, a total of 738 cities worldwide participated in this evaluation, of which only 120 achieved the highest score. Madrid is listed alongside other European capitals such as Barcelona, London, Paris, Milan, and Sofia, as well as cities from other continents like Sydney, Boston, Cape Town, or Rio de Janeiro.
The recognition was announced by Deputy Mayor Inma Sanz and the delegate for Urban Planning, Environment, and Mobility, Borja Carabante, who highlighted the value of this distinction as a reflection of the capital’s commitment to sustainability.
Sustainability and Adaptation Strategies
The A rating recognizes the work of the City Council within the framework of the Madrid 360 Environmental Sustainability Strategy, the Roadmap towards climate neutrality, and the strategic document Actions for the Climate Adaptation of the City of Madrid. These initiatives aim to:
- Minimize greenhouse gas (GHG) emissions.
- Promote adaptation to the adverse effects of climate change.
- Create a more livable, resilient, and low-emission city.
Madrid is also part of the European Covenant of Mayors for Climate and Energy and the European Mission of Climate-Neutral and Smart Cities, commitments that reinforce its leadership in climate action.
The Challenge of Climate Neutrality by 2050
The Spanish capital takes on the challenge of achieving climate neutrality by 2050, which involves transforming its urban model towards a more efficient city. The main axes are:
- Sustainable and low-emission mobility.
- Efficient building and reduction of energy consumption.
- Promotion of the circular economy.
- Green and blue infrastructure to improve environmental quality.
Iconic Projects Underway
Among the highlighted initiatives of the City Council in 2025 are:
- Northwest Green Walk: project for the renaturalization of degraded spaces and promotion of sustainable mobility.
- Strategy for the Prevention and Management of Domestic and Commercial Waste Madrid-2030: aims to reduce impacts on health and the environment, with a special emphasis on reducing GHG emissions and odorous substances.
Carbon Disclosure Project: The International Standard
The Carbon Disclosure Project (CDP) is an organization that manages the largest global platform for publishing environmental data and impact management. Considered the highest quality standard internationally, the CDP collects information from investors, companies, cities, and regions, and has the largest database of climate action plans from public and private corporations.
The revalidation of the A rating by Madrid confirms its position as an international benchmark in urban sustainability. With transformative projects and a comprehensive strategy, the city moves towards climate neutrality by 2050, demonstrating that environmental action is a central axis of its development.
