Sustainability permeates every idea, decision, process, and project that defines ACCIONA as a global leader in promoting sustainable development and addressing the climate emergency.
We support a sustainable business model that drives economic growth, social progress, and environmental balance, with the goal of improving the lives of current and future generations.
To achieve this, we design solutions to tackle the major global challenges humanity faces: decarbonising the energy system, addressing the climate emergency, resolving water and sanitation shortages, creating resilient infrastructures, and developing more sustainable cities.
We support the achievement United Nations' Sustainable Development Goals, which address the greatest challenges facing humanity.
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.
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.
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.
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.
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.
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.
In the remote Pacific islands, the struggle for survival in the face of climate change is not just an uncertain future, but a palpable reality. Through the story of Vepaia, a young woman from Vanuatu, journalist Amaro Gómez-Pablos reveals the urgency of climate justice, a cry of resistance that demands not only empathy, but immediate action. From the edge of the world, these small island nations face an existential threat as they seek a future that is not theirs, but which they must defend with unwavering resolve.
The world’s population is already over 8 billion inhabitants and the question is inevitable: how can we live well and in harmony on Earth? During 2025, we explored very different answers to this question: safer cities against the climate, truly circular energy, new economies, and even the power of language in changing realities, to name but a few. Below, you’ll find some of the stories that helped us imagine a more just and sustainable future.
The coasts of Java and the banks of the Citarum river accumulate plastic waste arriving there from everywhere in the world, while this region continues to lack in sanitation infrastructure. But both small and large initiatives, driven by citizens, NGOs and companies, have begun to change the situation, restoring rivers and protecting ecosystems.
Though we often forget it, our emotional well-being, interior calm and even creativity continues to respond to an ancestral stimulus – living close to nature. Biophilia – that “love for what lives” – is neither fashion nor romantic idea, but a deep human need scientifically proven in recent decades.
The hydraulic system at the Royal Palace of La Granja de San Ildefonso in Spain continues to be a model of efficiency and sustainability. With channels and fountains that function purely by gravity, the Royal Monument shows how intelligent design has ensured the responsible use of water for centuries.
COP30 ended with more funds for adaptation, progress in indigenous rights, and an issue still to be resolved – eliminating fossil fuels.
Our commitment to achieving universal access to basic services led us to create the acciona.org Foundation a decade ago. This platform enables us to reach isolated communities worldwide, providing them with sustainable and modern services like electricity, safe water, and infrastructure.
