What Root & Branch does

Root & Branch Digital Ltd is a Brighton- and London-based private company founded in 2024 that operates a green web hosting platform with integrated emissions reporting. Its core commercial offering is subscription-based managed hosting (SSL, daily backups, security monitoring, 99.9% uptime SLA) hosted on strategically selected low-carbon data centres, with every account including ISO-aligned energy and lifecycle emissions modelling as standard. A standalone Emissions Audits service extends the platform to large or complex web estates that require end-to-end measurement without a hosting engagement.

The platform is underpinned by Cardamon, an open-source research project funded by Innovate UK that implements ISO 21031 (Software Carbon Intensity) methodology for measuring energy and carbon across the full web stack — client device, browser rendering, network transfer, and server infrastructure. Cardamon positions itself as the first documented ISO 21031 implementation for end-user web activity, with an SCI for Cloud extension and statistical-sampling methodology for large sites in development (ETAs H1 and H2 2026). The company markets to three primary personas — web agencies (multi-domain audits, white-label reports), purpose-driven organisations (ISO-aligned, board-ready reporting), and digital-first businesses (high-traffic platform emissions management) — and is currently engaged in case studies with Wikipedia and GitHub to validate the methodology at very large scale. Revenue is generated through subscription hosting fees and project-based emissions audits, with quote-based pricing and no publicly disclosed rates; the company has disclosed no institutional equity funding and no revenue figures in the source data.
