Unicaja has managed to prevent the emission of 142,583 tonnes of carbon dioxide in 2025 with funds raised through the issuance of green bonds, representing a 76% increase compared to 2024, when 80,982 tonnes were prevented. This progress consolidates the growth in the bank’s positive environmental impact, which since 2022 has reached a cumulative volume of €2,100 million in this type of instrument.
These figures, which are part of Unicaja’s green bond allocation and impact report published today, reflect the bank’s growing contribution to the financing of projects aligned with the transition to a low-carbon economy.
The environmental impact of the projects has been calculated in accordance with international standards and guidelines, using a methodology developed by the external consultant Ecodes, whilst DNV has acted as an independent verifier, ensuring the objectivity, reliability and comparability of the results.
Since 2022, five green bond issues have been carried out, one of which has already matured, with the outstanding balance standing at €1,600 million at the end of the last financial year. All funds have been allocated to eligible projects, in accordance with the bank’s Green Bond Framework.
Renewable energy and sustainable buildings
Of the total amount funded, €442 million, corresponding to 35 projects, has been allocated to renewable energy initiatives – primarily solar photovoltaic, wind and solar thermal – whilst €1,158 million has been allocated to green buildings, with a total of 4,764 projects linked to mortgages for energy-efficient homes and sustainable property developments.
In the field of clean energy, the financed projects have generated 1,331,092 megawatt-hours (MWh) of renewable energy annually and have prevented the emission of 142,073 tonnes of carbon dioxide, with photovoltaic projects playing a particularly significant role.
The funds raised through these issuances are allocated to the financing or refinancing of projects that meet the criteria defined in Unicaja’s Green Bond Framework, which is aligned with the Green Bond Principles of the International Capital Market Association (ICMA).
These projects contribute to several United Nations Sustainable Development Goals (SDGs), particularly those related to affordable and clean energy (SDG 7), sustainable cities and communities (11) and climate action (13).
Among the initiatives financed, renewable energy generation projects stand out, such as photovoltaic and solar thermal plants, as well as housing developments with an A energy rating, which incorporate high standards of energy efficiency.
Social impact and territorial cohesion
In addition to their environmental impact, Unicaja’s green bonds generate significant social co-benefits. Approximately 50% of the eligible mortgages allocated have a positive social impact, as they are intended for young people under the age of 35 or are located in rural municipalities, thereby helping to improve access to housing and territorial cohesion.
This approach reinforces a concept of sustainable financing that incorporates environmental and social criteria, promoting more balanced development from a regional perspective.
