Supply chain decarbonization software company Green Project Technologies announced the acquisition of enterprise carbon accounting and reporting solutions provider Optera, with the transaction aimed at forming an end-to-end AI-powered climate management platform for companies.

Founded in 2006 initially as a boutique corporate sustainability consulting firm, and later shifting focus to software, Boulder, Colorado-based Optera provides sustainability management solutions designed to help companies reduce their climate impact across the value chain. The company’s products enable companies to develop and report audit-grade emissions figures across their entire operations, supply chain, and product life cycle.

Founded in 2021 by former Goldman Sachs strategist Sam Stark, New York-based Green Project Technologies provides solutions designed to help enterprises and their suppliers measure, manage, and reduce emissions across operations and value chains, including AI-powered solutions for carbon accounting, supplier engagement, reporting and renewable energy procurement as well as advisory services. The company was acquired in 2023 by environmental solutions provider ACT Group.

Tim Weiss, CEO and Co-founder of Optera, said:

“Optera was founded to help the largest companies in the world and their suppliers confidently transition to the low-carbon economy, from value chain decarbonization to regulatory compliance. Joining Green Project and ACT Group allows us to realize this vision at an incredible scale, with a truly global reach and end-to end solution.”

According to the companies, the transaction comes as sustainability reporting and compliance regulations including California’s SB 253 and the EU’s CSRD and CBAM increase pressure on companies to meet growing sustainability-focused legal obligations, with Scope 3 remaining the largest source of disclosure burden, supplier risk, and procurement cost exposure.

The companies added that the acquisition will enable them to provide a single platform for carbon accounting, supplier engagement, compliance reporting and decarbonization, including combining Green Project Technologies’ supplier engagement program with Optera’s audit-grade enterprise carbon accounting capabilities to enable users to identify emissions hotspots and target the highest-priority suppliers, and to connect to a decarbonization marketplace covering renewable energy certificates, insets, sustainable aviation fuel, and biomethane, as well as to access dedicated Sustainability Managers and global R&D experts on environmental markets and regulatory developments.

The transaction marks the latest in a series of acquisitions by Green Project Technologies, including the recent purchase of decarbonization planning software platform Zeroute, and the acquisition last year of Scope 3 emissions-focused carbon accounting solutions provider Emitwise.

Sam Stark, CEO and Founder of Green Project, said:

“For years, the sustainability industry has focused on measurement. Companies can calculate emissions, produce disclosures, and set targets, yet many still don’t know how to close the gap. Together with Optera, and backed by ACT Group’s global infrastructure, this is the platform that closes it: one place that meets enterprises and every one of their suppliers where they are and moves them from measurement to action.”

Colin Crooks, CEO of ACT Group, added:

“With Green Project Technologies and Optera, we’re bringing together enterprise software, global market access and execution capability in a way that is unique in our industry. Together, we’re helping organizations move beyond measuring emissions to accelerating decarbonization across their entire value chain.”
