Sam Stark is the CEO and Founder of Green Project Technologies, a supply chain decarbonization platform helping companies and their suppliers measure, manage, and reduce emissions across complex global value chains.

‍

Prior to founding Green Project in 2020, Sam worked in Goldman Sachs’ Energy and Sustainability group, where he supported the firm’s Net Zero commitments across its supply chain and private investments. Through this work, he saw firsthand that while organizations increasingly focused on direct emissions, the majority of their impact often sat within hard-to-track supply chains, and that existing tools were frequently complex and ineffective at engaging suppliers. This insight led him to found Green Project to close the gap between corporate climate commitments and supplier-level action.

Following Green Project’s acquisition by ACT Group and the acquisition of Emitwise’s Scope 3 decarbonization platform, the company expanded its platform and global reach. Under Sam’s leadership, Green Project continues to focus on end-to-end supply chain decarbonization, helping organizations mobilize their suppliers, empower them to take action, and drive measurable outcomes.

Sam is a Forbes 30 Under 30 and Huffington Post 20 Under 20 honoree and a graduate of Williams College. He works at the intersection of sustainability, technology, and global markets to help accelerate meaningful climate action.
