Green Project Technologies acquires Optera to unify climate management
Green Project Technologies, a subsidiary of ACT Group, has completed the acquisition of Optera, an enterprise carbon accounting platform whose clients include Target, John Deere, HPE, Intel and KKR. The deal merges Optera's audit-grade emissions measurement and reporting capabilities with Green Project's supplier engagement network and renewable energy procurement infrastructure, with the combined entity positioned by the company as a full-lifecycle AI climate management platform.
The timing is deliberate. Voluntary sustainability disclosure is becoming a legal obligation across major markets: California's SB 253 requires large companies operating in the state to disclose Scope 1, 2 and 3 emissions; the EU's Corporate Sustainability Reporting Directive (CSRD) and Carbon Border Adjustment Mechanism (CBAM) impose parallel obligations on European and importing entities. Green Project says the combined platform supports disclosure across at least ten frameworks, including CSRD, CBAM, CDP, SBTi, RE100 and SECR.
The deal
Sam Stark, chief executive and founder of Green Project, said the industry had spent years focused on measuring emissions without providing adequate tools for closing the gap. "Together with Optera, and backed by ACT Group's global infrastructure, this is the platform that closes it," he said. "One place that meets enterprises and every one of their suppliers where they are and moves them from measurement to action."
Green Project claims its supplier engagement programme covers more than 6,000 active suppliers across 100 countries. Adding Optera's decade of enterprise carbon management gives the combined business audit-grade accounting alongside that network. The platform is described as using AI agents to automate data ingestion, emissions mapping, and multi-framework reporting, with integration into a marketplace for renewable energy certificates, insets, sustainable aviation fuel and biomethane.
The transaction follows a series of acquisitions by Green Project: the purchase of Emitwise in 2025, the acquisition of Zeroute in June 2026, and strategic partnerships with Giki, FlexiDAO and HowGood. The release did not disclose deal terms for the Optera acquisition.
Market context
The climate-tech software market has seen significant consolidation as the regulatory pipeline hardens. A number of well-funded vendors, including Watershed, Persefoni, Salesforce Net Zero Cloud and SAP Sustainability, compete for enterprise Scope 3 accounting mandates, with buyers prioritising audit defensibility and regulator-accepted methodologies over self-reported benchmarks.
Scope 3 remains the most operationally complex disclosure category, requiring companies to gather data from suppliers that may themselves lack sophisticated measurement tools. Platforms that can address both ends of that supply chain relationship, enterprise buyer and tier-1 or tier-2 supplier, have a structural advantage as procurement teams are pressed to contractualise emissions requirements.
From a compliance standpoint, the EU AI Act's obligations on AI systems used in regulated reporting workflows will apply to platforms such as this one as the relevant provisions phase in over 2025 and 2026. Buyers will want assurance that AI-generated emissions figures and automated regulatory disclosures carry sufficient human oversight to satisfy auditors and regulators. Green Project says the platform holds SOC 2 certification and is GDPR-compliant, and claims a 100% success rate on greenhouse gas verification audits, though that figure is not independently corroborated in the release.
