About us

The Earthshot Prize is the world’s most impactful and prestigious environmental award. At the heart of our mission is a simple equation:
Urgency + Optimism = Action. Inspired by President John

F. Kennedy’s moonshot challenge, the Earthshot Prize mobilises a decade of action for the planet. We identify, celebrate, and back ambitious climate leadership from every corner of the globe – from Indigenous communities to city leaders, entrepreneurs to governments. We focus on five key Earth shots:
Clean Our Air, Fix Our Climate, Revive Our Oceans, Build a Waste‑Free World and Protect and Restore Nature. Each year we select a group of 15 finalists and award 5 £ 1 million each to help advance or replicate their work and recognise their achievement and potential.

The Senior Portfolio Manager sits within the Prize and Impact team, providing targeted support to help accelerate Earthshot Prize finalists and winners’ efforts to reach scale. You will work directly with a small number of finalists in our annual cohort to understand and shape their growth strategies, seek opportunities to leverage the Prize’s spotlight platform and unique network of partners, and help make those plans a reality.

This will involve cultivating a network of relationships with corporates, investors and policy‑makers who will be instrumental in helping our finalists scale. You will also support the creation of curated round tables, networking events, reporting tools and other assets that help our portfolio of finalists take advantage of growth opportunities. The role is essential in ensuring that finalists achieve exponential impact through leveraging the Prize’s unique platform and unprecedented global network.
