CaixaBank Corporate & Investment Banking (CIB) has signed a sustainable reverse factoring agreement with infrastructure group Acciona, providing a supply chain finance solution that links financing terms to suppliers’ sustainability performance.
Reverse factoring allows a buyer to manage payments to its suppliers through a financial institution, giving suppliers the option to receive early payment on approved invoices. Under this structure, suppliers can access liquidity without increasing their balance-sheet debt, potentially lowering default risk.
The sustainable reverse factoring arrangement incorporates environmental, social and governance (ESG) criteria. CaixaBank said it has applied a proprietary tier-based ESG scoring system to assess Acciona’s suppliers, with those demonstrating stronger sustainability practices eligible for more favourable financing conditions.
More than 4,500 Acciona-approved suppliers are expected to be eligible for the facility. The bank said the structure is designed to support working capital management while encouraging suppliers to improve their sustainability performance.
The financing solution has received the Innovation of the Year award at Environmental Finance’s IMPACT Investment Awards 2025, which recognise financial products that aim to generate environmental or social benefits.
CaixaBank’s current strategic plan includes a target to mobilise €100 billion in sustainable finance between 2025 and 2027. The bank reported that it mobilised more than €86 billion in sustainable financing over the 2022–2024 period, exceeding its previous target of €64 billion.
Acciona said the facility will be used as an additional mechanism to support supplier engagement on sustainability as part of its broader supply chain programmes.
Acciona operates globally across renewable energy, water treatment, transport and infrastructure, and has reported carbon neutrality since 2016. The company recorded revenues of €19.19 billion in 2024 and operates in more than 40 countries.
