Honest Mobile is the UK's only carbon negative and the only B Corp certified mobile network. A member of 1% for the Planet and a living wage employer and so much more.

Spherics is a cloud-based, data-driven software platform, enabling businesses large and small to understand their carbon footprint and make net-zero a reality. Our platform uses a clever combination of technology and climate science expertise, to help businesses measure, mitigate and manage their environmental impact. We do this by automating the collection of their spend data, to generate an accurate and robust carbon impact, in line with the GHG protocol, across all three scopes of emissions (1, 2 and 3). We then present them with the insights they need to understand their carbon impact and the actions that can bring them in line with the latest science-based targets. We’ve been recognised as the best early-stage climate tech in the UK by TechNation, winning the Rising Star Award in 2021.
