Verdict

Greenly and Plan A both target the European mid-market with a combination of Scope 1, 2 and 3 carbon accounting and CSRD-aligned reporting, and both position themselves against the largest US-focused enterprise platforms by offering a more accessible, guided entry point. The real difference is what each leads with. Greenly's product is organized as an explicit maturity ladder — three named tiers moving from baseline GHG compliance to supplier engagement to a full net-zero program — aimed at companies that have never run an inventory before. Plan A leads with its CSRD-aligned double-materiality and reporting module built alongside carbon accounting from the start, aimed at companies for whom double materiality, not just emissions, is the near-term deadline.

Both calculate emissions from spend and activity data through accounting and ERP integrations, support supplier engagement for Scope 3, and produce dashboards for internal and external reporting. Neither publishes tier pricing; both sell by quote or after a demo.

Choose Greenly if

  • Your team has not run a carbon inventory before and wants a guided path from compliance reporting up to a full reduction program.
  • You want the option to start at a lighter GHG Report Compliance tier and grow into supplier engagement later, rather than buying full scope on day one.
  • SME-scale support and a lower-friction onboarding matter more than a deep enterprise feature set.

Choose Plan A if

  • CSRD double materiality is your most immediate deadline, not just emissions accounting.
  • You want materiality assessment and carbon accounting built on the same underlying data from the start, rather than added later.
  • You are already mid-market or enterprise scale and need a platform sized for that, not a first-time-reporter ladder.

What they share

Both are Europe-headquartered, both build toward CSRD specifically rather than only the GHG Protocol in the abstract, and both support supplier engagement workflows for Scope 3 data collection. Neither publishes list prices, so the decision in practice comes down to a demo of each vendor's materiality and reporting workflow against your own reporting calendar.
