In a move set to streamline ESG compliance worldwide, ESG Book and Boston Consulting Group (BCG) have unveiled LEO, a next-generation sustainability reporting platform.

Built on Google Cloud, LEO aims to alleviate the mounting burden of ESG disclosure through smart AI-driven automation and seamless integration with leading frameworks such as ISSB and GRI.

Designed as a modular, framework-neutral system, LEO empowers corporates and financial institutions to navigate complex disclosure requirements with ease. Key features include AI-powered pre-fill capabilities, automated data mapping, and secure, standardised information-sharing—reducing the need for repetitive questionnaires and enhancing supplier engagement.

Already adopted by financial giants like ING, Lloyds, and NatWest, LEO is positioned as a key infrastructure tool to help businesses manage sustainability-related risks, improve supply chain resilience, and meet regulatory standards across more than 30 jurisdictions. With over 200,000 existing disclosures feeding its smart pre-fill system, the platform drastically cuts time and cost for ESG teams, freeing them to focus on value creation.

Stakeholders from IFRS, GRI, and Google Cloud have voiced strong support. Andrew Brenner of IFRS said the tool arrives at a critical moment, as countries representing 60% of global GDP move toward ISSB compliance. Meanwhile, Google’s Justin Keeble called LEO “a powerful way to make ESG performance tracking smarter and more efficient.”

The collaborative development between ESG Book and BCG also leans heavily on BCG’s sustainability data templates, giving the platform added credibility in a fast-evolving compliance landscape. Roy Choudhury of BCG highlighted its relevance for both large corporates and privately held firms, which often lack standardised sustainability disclosures.

With LEO, ESG Book and BCG aim not just to digitize ESG reporting—but to redefine it for a world where sustainability data drives strategic decisions, risk management, and market leadership.
