The ENGAGE for ESG Consortium is pleased to announce that Onesto, a Belgium-based social lender committed to sustainable and affordable housing, has joined ENGAGE for ESG as a trial user.
From October 2025, Onesto will work with the ENGAGE Templates and Portal—innovative tools developed under the EU-funded ENGAGE for ESG project—to assess the Taxonomy alignment of its mortgage and home renovation loan portfolio in a systematic and structured manner. As part of this process, Onesto will begin uploading credit and sustainability information to the ENGAGE Portal, further enriching the ESG data available on the platform.
“We are delighted to welcome Onesto to the ENGAGE for ESG community,” said Marco Angheben, ENGAGE Project Coordinator and Head of Business Development & Regulatory Affairs at European DataWarehouse. “Their participation confirms the relevance of ENGAGE Solutions in addressing the ESG disclosure challenges faced by lending institutions. Their expertise in real estate financing will also help enhance and evolve the ENGAGE tools.”
Joris Piette, Project Manager and COO at Onesto, added: “By working with the ENGAGE Templates and Portal, we gain a crucial puzzle piece in our mission to make sustainable homeownership attainable for low-income first-time buyers. The structured ESG data and Taxonomy insights from ENGAGE allow us to connect impact measurement to real people’s housing journeys — ensuring that sustainability and affordability go hand in hand.”
Vincent Mahieu, Head of Energy Efficiency & Regulatory Technology at Hypoport, added: “Onesto’s decision to use the ENGAGE Templates and Portal demonstrates true leadership in sustainable housing finance in Belgium. By investing in robust data and transparent processes, Onesto strengthens the link between sustainability, affordability and inclusion. Through ENGAGE for ESG, lenders gain access to detailed insights on energy efficiency and building performance, creating a transparent basis for measuring and improving the environmental impact of mortgage portfolios. Onesto’s participation will help reduce energy poverty, support more accessible housing for Belgian households and show how financial innovation can contribute directly to the European Green Deal.”
Cátia Alves, Corporate Sustainability Director at Unión de Créditos Inmobiliarios (UCI), states: “At UCI, we welcome Onesto’s incorporation into the ENGAGE Portal, a key tool for advancing transparency and standardisation of ESG data in the financial sector. As project partners, we firmly believe that initiatives like this enable institutions like Onesto to strengthen their commitment to sustainability, inclusion, and the fight against energy poverty. Collaboration is essential to accelerate the transition towards affordable and energy-efficient housing.”
Authorised parties, including investors, consultants, and regulatory authorities, will be able to access Onesto’s uploaded information, as well as the corresponding ENGAGE data quality and EU Taxonomy alignment reports, subject to Onesto’s approval.
European lending institutions are invited to participate in the ENGAGE for ESG initiative as test users, giving them exclusive access to the EU Taxonomy assessment until June 2026, by emailing engage4esg@eurodw.eu.
