Job description

ABOUT CO2 AI

CO2 AI helps some of the world's largest companies understand and cut their environmental footprint. We deliver that value in two ways: through our platform, which runs product level carbon footprints at scale and models decarbonisation levers, and through the industrial applied AI use cases we deliver alongside it. What our clients are after is not a dashboard, it is outcomes: decisions taken, levers activated, emissions actually coming down.

We spun out of BCG in 2023. We are 45 people based in Paris, with teammates in the US and the UK, and our working language is English.

As a Sustainability & AI Consultant Intern at CO2 AI, you will support our team of Value Consultants as they help leading organizations translate their sustainability ambitions into measurable business value.

• The mission. You spend your days on climate, on a product that moves real numbers for some of the largest emitters in the world

• People who care. Everyone here chose this work. Climate is not a side project at CO2 AI, it is the whole point
