Triodos Bank publishes impact report addressing the impact of energy and mortgage financing
Triodos Bank’s Impact Report 2024 introduces a new impact calculation methodogy, developed together with us at Impact Institute, which transparently shows both the externalities and positive outcomes per euro invested in wind energy, solar energy, battery storage, and sustainable and biobased mortgages – setting the standard for the finance industry to do better.
Key takeaways
Calculates Tangible Environmental & Social Benefits
Across energy and housing, Triodos’ financing avoided 875 kilotons of CO2 (valued at € 170M) and € 69M in air pollution costs, contributing to healthier communities and ecosystems.
Impact Valuation allows for the Calculation of Real Returns
Triodos’ energy transition portfolio generates a 14% impact return, avoiding €0.14 worth of environmental impact for every euro of financing.

Showcases the value of pioneering products
Triodos Bank offers clients bio-based mortgages which promote the construction of homes using plant-based materials and reduce environmental impact by 42%.
Transparency on negative impacts
Financing decisions still lead to negative environmental and social impacts. In particular, the renewable energy sector has significant negative impacts arising from the construction of solar panels, batteries, and wind turbines.
A Blueprint for Sustainable Finance
By going beyond regulatory requirements (CSRD) and prioritizing transparent methods and disclosures, Triodos hopes to drive the financial sector towards transparency on the true impact.
