Our vision

Zellar’s mission is to help 250,000 organisations take measurable sustainability action by 2028 — from SMEs and franchises to sports clubs, schools, healthcare, and councils.

Our route to that goal is through partnership: working with the large organisations that already reach these smaller ones — supply chain owners, funders, membership bodies, and councils.

By helping them capture emissions data from the hard-to-reach tail through automation and APIs, Zellar makes it simple to measure collective impact — while leaving behind a platform every SME can use to keep improving.

What started as a frustration has become a movement — one platform helping every organisation, large or small, take real, measurable climate action.
