Takeaways

• Green Project Technologies acquires Optera to build an AI-powered end-to-end climate management platform for enterprises.
• The combined platform will bring together carbon accounting, supplier engagement, compliance reporting, and decarbonization tools in one solution.
• The move comes as regulations such as CSRD, CBAM, and California SB 253 increase demand for accurate emissions reporting and supply chain transparency.

Green Project Technologies has acquired enterprise carbon accounting platform Optera in a move that expands its climate technology capabilities and strengthens its position in the fast-growing sustainability software market. The acquisition is designed to create a single AI-powered platform that helps businesses measure, report, and reduce emissions across their operations and supply chains.

The deal combines Green Project Technologies' expertise in supplier engagement and emissions reduction with Optera's enterprise-grade carbon accounting and reporting capabilities. Together, the companies aim to offer organizations a complete solution that supports carbon measurement, regulatory compliance, and decarbonization planning.

Founded in 2006, Optera began as a sustainability consulting firm before shifting its focus to software. The Colorado-based company provides tools that help businesses produce audit-ready emissions data across operations, supply chains, and product life cycles. Its platform enables organizations to track climate performance while meeting growing reporting requirements.

Green Project Technologies, established in 2021 by former Goldman Sachs strategist Sam Stark, develops AI-powered software that enables enterprises and suppliers to measure, manage, and reduce greenhouse gas emissions. Its services include carbon accounting, supplier engagement, renewable energy procurement, sustainability reporting, and advisory support. The company became part of ACT Group in 2023.

The acquisition comes at a time when companies face increasing pressure to comply with sustainability regulations. Rules such as California's SB 253, the European Union's Corporate Sustainability Reporting Directive (CSRD), and the Carbon Border Adjustment Mechanism (CBAM) are driving demand for more accurate emissions reporting. Scope 3 emissions, which often account for the largest share of a company's carbon footprint, continue to present significant reporting and supplier management challenges.

By combining their technologies, the companies plan to offer a unified platform that helps businesses identify emissions hotspots, engage priority suppliers, and accelerate decarbonization efforts. Users will also gain access to a marketplace offering renewable energy certificates, biomethane, sustainable aviation fuel, and carbon insets, alongside guidance from sustainability specialists and environmental market experts.

Tim Weiss, CEO and Co-founder of Optera, said the partnership would allow the company's mission to scale globally. He noted that combining with Green Project Technologies and ACT Group would help support large organizations and their suppliers in transitioning to a low-carbon economy while addressing regulatory requirements.

The acquisition continues Green Project Technologies' expansion strategy. The company recently acquired decarbonization planning platform Zeroute and last year purchased Scope 3 carbon accounting provider Emitwise, adding further capabilities to its climate software portfolio.

Commenting on the transaction, Green Project Technologies Founder and CEO Sam Stark said many businesses have become better at measuring emissions but still struggle to turn data into meaningful climate action. He said the combined platform is intended to bridge that gap by giving enterprises and suppliers a single system to move from emissions reporting to practical decarbonization.
