ACCIONA concluded its 2021–2025 Sustainability Master Plan (2025 SMP) last year with 89.8% of its total 2025 revenue aligned with business and economic activities considered sustainable under the European Union’s taxonomy. At the start of the period, this ratio stood at 46.7% (+43.1 percentage points). Furthermore, the share of sustainable investments remained consistently well above 90% throughout the five-year period, reaching 98.2% by the end of the plan, and totaled over €12.3 billion. These figures demonstrate the consolidation of the group’s sustainable business model.

ACCIONA succeeded in decoupling growth from emissions thanks to the introduction of various measures such as energy efficiency, renewable energy consumption (79% of the total in 2025), electrification of the machinery and vehicle fleet, and the replacement of diesel fuels with biofuels. In this way, sales—excluding Nordex, which has been fully consolidated only since April 2023—grew by 96% over the five-year period, while emissions decreased by 17.8%, exceeding the target set by the 2025 SMP.

Scope 1 CO2 emissions (direct emissions from fuel consumption) and Scope 2 emissions (indirect emissions from purchased energy), excluding Nordex, totaled 165,005 tCO2e (tonnes of carbon dioxide equivalent).

In addition, the growth in installed renewable energy capacity helped increase the company’s positive impact. ACCIONA generated 27,648 GWh of clean energy in 2025, preventing the emission of more than 15.7 million tCO2e (with an 18.9% improvement over the five-year period).

By the end of 2025, the group accelerated the use of renewable and recycled resources (a 25% share compared to 11% in 2020), reduced the amount of waste sent to landfills by 59%, and planted more than 1.1 million trees.

Over the five-year period, ACCIONA integrated a system for monitoring environmental and social risks and opportunities into the business option evaluation process, which is now applied to 100% of new projects.

In terms of measuring and reporting impact, the company has implemented Minerva, a system for tracking sustainability performance indicators on a project-by-project basis.

 

INNOVATION STRATEGY

The innovation priorities established under the 2025 SMP framework channeled more than €1.5 billion towards three strategic areas over the five-year period:

• Regeneration, with the aim of maximizing the positive impact on social and environmental systems.
• Collaboration, as a lever to join forces with other actors—primarily startups and social economy organizations—that bring unique capabilities to address the challenges of sustainable development.
• Digitalization, as a foundation to drive efficiency, scalability, and data-driven decision-making.

In 2025, ACCIONA reported an innovation investment of €369.6 million (+10.58%) for 159 projects.

 

SOCIAL IMPACT

During the 2025 SMP period, ACCIONA consolidated the use of GIS, its proprietary system for managing social impact, which enables the company to engage and work effectively with the communities where it operates, to document its activities, and to subject the entire process to independent review by external experts. At the end of the period, the methodology was applied to 314 projects in 31 countries, benefiting nearly 2.2 million people with an investment of almost €15 million in social initiatives.

The share of women in managerial and executive positions stood at 22.9% at the end of 2025, compared to 20.7% in 2020. Last year, the group had 21 of its 50:50 projects underway in eleven countries, as part of its strategy to boost female employment in the infrastructure sector, where women have traditionally been underrepresented.

The workforce totaled 68,502 people in 2025 (+78.6% over the five-year period). Inclusive employment programs ensured that 2.4% of jobs were held by people with disabilities, rising to 4.9% in Spain.

The company transformed its financing system over the five years of the 2025 SMP. In total, ACCIONA structured 37 financial instruments totaling almost €13.43 billion under its Sustainable Impact Financing Framework. By the end of 2025, 84% of the group’s gross corporate debt was classed as “sustainable financing.”

The Sustainable Impact Financing Framework approved in 2023 integrates both green financing instruments and financing structures linked to sustainability performance. Its unique value lies in the fact that it introduces an additional component of local impact to enhance environmental and social outcomes in the areas surrounding the company’s operations, resulting in a “dual-impact” structure.

 

VALUE CHAIN

In terms of governance, supply chain risk management systems have become a tool for control, traceability, and operational resilience within an ecosystem that includes 29,822 active suppliers operating in nearly 100 countries.

The Supply Chain Risk Management model is fully integrated as a group standard and now covers 98.8% of total procurement volume. This system strengthens due diligence processes, including the expansion of audits to tier-2 suppliers, and has been validated by the ISO 20400 certification in Sustainable Procurement.
