Green Project Technologies Acquires Optera to Build Combined Carbon Platform

Green Project Technologies, part of ACT Group, has acquired enterprise carbon accounting platform Optera, combining Green Project's supplier engagement network of more than 6,000 active suppliers across over 100 countries with Optera's decade of enterprise carbon reporting used by companies including Target, John Deere and Intel. The deal creates what the companies describe as an integrated platform spanning carbon measurement, supplier engagement and renewable energy procurement, arriving as regulations including California's SB 253, the EU's Corporate Sustainability Reporting Directive and the Carbon Border Adjustment Mechanism turn voluntary sustainability disclosure into a legal requirement across multiple markets.

 

Why Scope 3 Emissions Are the Hardest Problem to Solve

 

The acquisition targets a specific bottleneck in corporate climate reporting: Scope 3 emissions, the indirect emissions occurring across a company's supply chain rather than its own operations. Scope 3 typically represents the largest share of a company's total footprint by far, yet it is also the hardest to measure accurately because it requires gathering data from suppliers who may have limited resources, inconsistent reporting practices, or no incentive to prioritise a customer's disclosure needs over their own operations.

That measurement gap has become more consequential as disclosure shifts from voluntary reporting to legal obligation. Regulations such as CSRD in Europe and California's SB 253 increasingly require companies to report Scope 3 data with audit-grade rigour, turning what was once a best-effort estimate into a compliance requirement with legal consequences for inaccuracy. Green Project's chief executive Sam Stark framed the industry's historical focus as measurement without a clear path to closing the gap between calculating emissions and actually reducing them, positioning the combined platform as addressing execution rather than just disclosure.

How the Combined Platform Fits Together

 

The acquisition pairs two different capabilities that together span a company's full emissions reporting and reduction workflow. Green Project's supplier engagement programme reaches thousands of suppliers directly, using automated tools to identify which suppliers represent the largest emissions hotspots and target outreach accordingly, rather than requesting the same data uniformly from every supplier regardless of their actual contribution to a company's footprint. Optera contributes audit-grade enterprise carbon accounting, the more rigorous measurement and reporting layer that regulated companies need to satisfy disclosure requirements.

Layered on top is what the companies describe as an integrated decarbonisation marketplace, covering renewable energy certificates, carbon insets, sustainable aviation fuel and biomethane, with no minimum purchase volumes. That marketplace component matters because it gives companies a direct route from identifying an emissions reduction opportunity to actually purchasing the instruments needed to address it, rather than requiring them to separately source those products through other channels once their reporting has identified where reductions are needed.

A Pattern of Consolidation in Carbon Management Software

 

The Optera acquisition extends a run of consolidation for Green Project, following its 2025 acquisition of Emitwise, a June 2026 acquisition of Zeroute, and recent partnerships with Giki, FlexiDAO and HowGood. That pace of acquisition reflects a broader trend in the carbon management software sector, where a proliferation of point solutions, tools covering only measurement, only supplier engagement, or only renewable energy procurement, are increasingly being consolidated into single platforms as enterprise buyers seek to reduce the number of vendors they manage across their sustainability stack.

ACT Group chief executive Colin Crooks framed the combination as bringing together enterprise software, global market access and execution capability in a way the company described as distinctive in the industry, extending the platform's reach through ACT's existing infrastructure for renewable energy instruments across more than 100 countries. Whether the combined platform succeeds in moving enterprises from measurement to measurable emissions reduction at scale, and whether continued acquisitions extend its capabilities further before competitors consolidate similarly, will determine how much this deal reshapes the market for corporate carbon management software.
