Built for real businesses, not climate PhDs.
Most UK SMEs don't have a sustainability team. Greenio gives you a clear, credible carbon account with the minimum amount of noise — built for operations, finance and compliance teams.
Simple by design
No messy spreadsheets or confusing factors. Add usage or spend, choose a category, and let the platform calculate CO₂e with UK-standard methods.
UK-ready outputs
Generate clean carbon accounts and summaries for boards, investors and customers. Perfect for tenders, compliance and net-zero goals.
Fair, transparent pricing
Start free, upgrade when accounting becomes regular. No long contracts, no consultancy upsell.
Trusted by UK operations and finance teams.
Carbon Central fits into the real world of busy teams, not climate consultants. Here’s how customers are using it today.
Early customers from logistics, professional services and tech.

“We pulled together a credible footprint in a single afternoon. No one on my team is a sustainability expert, and that’s the point — the product isn’t built for experts.”
