THE PATH TO DESIGNING A BETTER PLANET
CLEAN WATER AND SANITATION
Ensure access to water and sanitation for all.
Over 2.000 million people in the world live without access to a basic drinking water service, and 3,6 billion have no access to a basic sanitation service, resulting in avoidable deaths, chronic disease, fewer hours of education and low productivity.
ACCIONA has positioned itself as a key player in the water treatment sector. Its innovative management seeks to resolve the challenges with respect to the shortage of water resources.
EXPLORE OUR WATER SOLUTIONS AFFORTABLE AND CLEAN ENERGY
Ensure access to affordable, reliable, sustainable and modern energy.
One in eight people still lack access to electricity. To ensure access to affordable, reliable, sustainable and modern energy for all, the use of renewable energy has to increase from the current 25% to 38% by 2025.
ACCIONA is leading the corporate fight to mitigate the effects of the climate emergency and accelerate change towards a decarbonised energy model. We are the largest 100 % clean energy company in the world.
DISCOVER OUR ENERGY SOLUTIONS INDUSTRY, INNOVATION AND INFRASTRUCTURE
Build resilient infrastructure, promote sustainable industrialization and foster innovation.
Economic growth, social advancement and action against the climate emergency depend largely on investment in infrastructure, sustainable industrial development and technological progress. Today, about 1 billion people live more than 2 km from a roadway, 940 million live without electricity, and 663 million lack improved drinking water sources.
ACCIONA participates in the entire infrastructure construction value chain, from the identification of opportunity, design and execution, to the operation and maintenance of the constructed works, using the most advanced and innovative techniques.
Performance quality and safety are two of the criteria that maximize the company's value proposal in the development of large infrastructure projects and that differentiate it from other competitors in the construction field.
DISCOVER OUR TRANSPORT SOLUTIONS EXPLORE OUR SOCIAL SOLUTIONS DISCOVER OUR REAL ESTATE SOLUTIONS SUSTAINABLE CITIES AND COMMUNITIES
Make cities and human settlements inclusive, safe, resilient and sustainable.
Today, cities represent 3 % of the planet's surface and concentrate more than 50 % of the population. A figure that will rise to 70 % by 2050. In addition, cities generate more than 80 % of the world's gross domestic product (GDP).
In addition to facilitating access to essential services for life - such as energy and water - ACCIONA contributes to making cities places of productive well-being in which to live, favouring people's socio-economic development.
DISCOVER OUR URBAN SOLUTIONS EXPLORE OUR SOCIAL SOLUTIONS DISCOVER OUR REAL ESTATE SOLUTIONS CLIMATE ACTION
Take urgent action to combat climate change and its impacts.
The generation and use of energy accounts for 74 % of total greenhouse gas emissions in the world. This activity is the largest contributor to global warming. Investment in renewable energy, energy efficiency and other low-carbon technologies will continue to be essential to meet the emerging needs of humanity and to minimize their negative impact on the environment.
ACCIONA considers the fight against climate change and its effects to be a strategic priority. The company works to mitigate greenhouse gas emissions in order to contribute to the progress of society and respond to the main challenges of sustainable development in the areas of infrastructure, water and energy, leading the transition to a low-carbon economy.

We fight against climate change
emissions avoided through renewables-based generation
Thanks to our renewable energy projects around the world, we manage to avoid the emission of millions of tons of CO₂
How do we calculate using the emissions counter? The total CO₂ emissions avoided over a period is calculated by summing the emissions avoided in each country where ACCIONA generates renewable electricity, based on the specific emission factor of each country.

Japan’s resilient architecture in the face of earthquakes
Japanese innovation holds an often-overlooked dimension: its earthquake-resistant engineering. In a country exposed to relentless seismic activity, its architecture shows the vital need to build increasingly resilient structures capable of withstanding both natural hazards like earthquakes and extreme events compounded by climate change.
