Madrid, November 18, 2025 – Allianz, one of the world’s leading insurance groups, and Manglai, a technology platform specialized in corporate sustainability, announce a strategic partnership to help Spanish companies measure and reduce their carbon footprint.
The solution developed allows companies to calculate Scope 1, 2, and 3 emissions quickly and automatically, in line with standards such as the GHG Protocol and ISO 14064. The platform leverages artificial intelligence and data on energy consumption, mobility, and waste, generating visual reports ready for audits, tenders, or communication with clients and investors.
This collaboration responds to a shared objective: making sustainability accessible to more companies through technological solutions that are affordable, effective, and scalable. Allianz has contributed its deep knowledge of the business ecosystem and its distribution network, while Manglai has led the technological development, ensuring a robust, automated, and user-friendly platform.
“Allianz is a key player in the sustainable transition. Having an organization of this scale trust Manglai to co-create solutions is a strong validation of our agile, technology-driven approach,” says Andrés Cester, CEO of Manglai.
“Our mission is to make sustainability measurable, strategic, and operational for any company.”
The solution is already being used within Allianz’s digital ecosystem, supporting hundreds of companies in Spain. It enables organizations to measure emissions, generate visual reports, and comply with regulations in a simple and efficient way.
Allianz is one of the most internationally recognized insurance companies, with a strong commitment to sustainability and the green transformation of its network of clients and suppliers.
