Our Journey
From founding insights into supply chain emissions to a platform enterprises and suppliers rely on.
Founded in 2021 by Sam Stark, Green Project was built to help enterprises and their suppliers measure, manage, and reduce emissions across operations and value chains. While working in Goldman Sachs' Energy and Sustainability group, Sam saw how the largest emissions sit deep within complex supply chains, and how existing tools struggled to engage suppliers effectively. That gap shaped the vision for Green Project.
Since then, the platform has grown quickly and deliberately: adding Emitwise's AI-driven supplier engagement and automated PCF functionality in 2025, Zeroute's decarbonization planning capabilities in June 2026, and Optera's audit-grade enterprise carbon accounting, trusted by Fortune 500 sustainability teams, in July 2026.
Together, the platform gives enterprises and their suppliers a single place to measure emissions, coordinate action, and turn carbon data into meaningful progress across the value chain, backed by a team with experience from SBTi, ERM, Malk Partners, and Oliver Wyman.
