Novisto Acquires Carbon Management Platform Minimum to Build End-to-End Sustainability Software

Sustainability reporting software provider Novisto announced the acquisition of London-based carbon management company Minimum, combining Minimum's granular carbon inventory capabilities with Novisto's full ESG data management and reporting platform. The deal follows a USD 27 million financing round by Novisto last year to enhance its platform and expand internationally.

Founded in 2020, Minimum provides a carbon management platform covering collection, calculation, and reporting of corporate carbon footprints, including its Carbon Atlas tool for mapping and managing environmental inventories across large organizations. Novisto, based in Montreal, provides sustainability data management and reporting software enabling companies to collect ESG data, adapt to changing frameworks, and streamline reporting. The acquisition will integrate Minimum's flexible data ingestion capabilities, which allow connection to utility providers and other external systems, to produce a granular, audit-ready carbon inventory with full traceability.

Novisto CEO Charles Assaf said the acquisition delivers a unified system of record for large organizations managing climate impact and regulatory obligations. The integration is designed to meet demand driven by new reporting regulations including the EU's CSRD, the UK's Sustainability Reporting Standards, and California's SB 253, which require detailed, verifiable emissions data. Minimum CEO Chris Winchurch noted that customers seeking depth and accuracy in carbon accounting increasingly require that capability within a full ESG platform, which the acquisition now provides.

The deal reflects accelerating consolidation in the sustainability software market as providers build out full-stack capabilities spanning raw data ingestion, carbon accounting, ESG metric management, and multi-framework reporting. For large Indian listed companies navigating SEBI's BRSR Core requirements and voluntary adoption of ISSB standards, integrated platforms that combine audit-ready carbon data with broader ESG reporting functions address a growing compliance and operational need. The acquisition positions Novisto to compete more directly with larger enterprise sustainability software platforms.
