Supply chain decarbonization
Sam Stark, CEO and Founder of Green Project Technologies, talks tackling Scope 3 emissions across complex food supply chains
Can you tell us about your career journey and what led you to found Green Project Technologies? I started at Goldman Sachs supporting energy and sustainability work, including the firm’ s own net-zero goals. What struck me was the share of emissions sitting within complex supply chains, and how existing tools simply weren’ t built to effectively engage suppliers at scale who may lack the resourcing, budget or expertise to start their own in-house climate programs. That insight shaped everything.
I founded Green Project in 2020 because credible net-zero progress means making climate solutions accessible not just to big corporations, but to the thousands of smaller companies sitting behind them. We’ ve been
Scope 3-focused from day one. Since then, we’ ve grown rapidly, and in 2023 became part of ACT Group, which has accelerated our ability to deliver at scale. Today we work with procurement teams and their supplier bases across more than 50 countries.
The food and beverage sector accounts for a significant share of global emissions. Where in the value chain do you see the biggest opportunities for rapid reduction? The honest answer is that the emissions are spread across the entire chain, from farm inputs and ingredients through to packaging, logistics, and end of life. Each part operates under different constraints, which is what makes food and beverage uniquely complex.
