The bank has raised or facilitated EUR 174 billion since 2019 as it edges closer to its ambition of EUR 220 billion by 2030.
Santander acted as adviser on several of the world’s largest renewable energy transactions and it supported customers through initiatives such as assessments on the robustness of their transition plans, advice on key levers for improvement, and help with managing climate risks to move towards achieving the targets set for high-emission sectors.
The most salient examples include advice to major energy companies Equinor and Polenergia on the financing of two offshore wind projects in Poland (the largest financing ever obtained in Poland and Santander's largest project finance advisory deal to date) and the bank’s role as financial adviser to Origis Energy in Brookfield & Antin's strategic investment to support the growth of its large-scale solar energy unit with BESS in the United States.
