ESG Book, in collaboration with Boston Consulting Group (BCG), has launched LEO, a new platform designed to streamline sustainability disclosures. Built on Google Cloud infrastructure, the tool is intended to support companies and financial institutions in meeting complex and evolving regulatory reporting requirements.
Amid growing scrutiny around environmental, social and governance (ESG) performance, firms are under increasing pressure to disclose reliable, comparable sustainability data. However, shifting disclosure mandates risk creating further inefficiencies and widening information gaps, particularly for financial institutions reliant on consistent inputs from corporate clients.
LEO has been introduced as a response to these challenges. Described by its developers as a modular and framework-neutral solution, the platform allows organisations to tailor disclosure and data collection processes across jurisdictions and sectors. It incorporates a reporting template that aligns with major global standards, including those of the International Sustainability Standards Board (ISSB) and the Global Reporting Initiative (GRI). Smart features such as pre-filling capabilities based on existing disclosures are designed to reduce manual reporting burdens.
The platform has been adopted or piloted by several leading banks, including ING, Lloyds and NatWest, in an effort to improve data sourcing, streamline compliance preparation, and build operational resilience.
Justin Fitzpatrick, CEO of ESG Book, said: “As regulatory requirements evolve, managing risks and leveraging sustainability as an economic driver remains crucial for corporates and financial institutions. LEO cuts through complexity, simplifies reporting, and helps businesses focus on what matters – using data to drive efficiency, reduce costs, and create long-term value.”
Roy Choudhury, Managing Director and Senior Partner at BCG, added: “As the demand for reliable and comparable climate-related information continues to grow, a standardised data request and reporting template is essential. Our collaboration on the LEO platform leverages BCG’s intellectual property and sustainability expertise to foster an innovative response to this challenge.”
The platform has also received backing from figures across the sustainability and financial sectors. Caroline Haas of NatWest said the tool could help business clients better manage their sustainability reporting, while GRI’s Cristina Gil White highlighted its alignment with GRI standards. Andrew Brenner from the IFRS noted the importance of platforms such as LEO in supporting the global rollout of ISSB-aligned disclosures.
Google Cloud’s Justin Keeble emphasised the role of technology in easing the administrative burden of reporting: “Businesses need to focus on driving sustainable growth, efficiency, and resilience rather than being burdened with complex reporting and disclosure requirements.”
LEO is intended to serve a broad range of users, from SMEs to multinational firms, and seeks to standardise ESG reporting practices in line with global disclosure developments.
