Carbon accounting and decarbonisation SaaS for GHG measurement, CSRD reporting and net-zero targets.
Updated August 2026 · By the ERP Research Editorial Team · Independent and vendor-neutral.
Plan A is a European carbon accounting and decarbonisation platform that helps companies measure, report and reduce greenhouse gas emissions across Scopes 1, 2 and 3. The platform centres on a company dashboard that aggregates emissions by scope, category, department, facility or custom dimension, using activity-based, spend-based or average-data calculation methods aligned with the GHG Protocol.
Beyond measurement, Plan A covers stakeholder-ready carbon reporting, a dedicated CSRD reporting module, and regulatory guidance spanning CSRD, ESRS, CSDDD, the EU Taxonomy, UK SDR, US SEC climate disclosure rules and CBAM. Its decarbonisation tooling supports science-aligned target setting, emissions forecasting and reduction-action tracking, backed by in-house carbon accountants and policy experts, plus a generative-AI assistant (Gaia AI) for sustainability queries.
The company was founded in 2017 and is headquartered in Berlin with additional offices in Paris, London and Munich; it describes itself as a leading European provider of corporate carbon accounting and decarbonisation software. Plan A was acquired by Diginex (NASDAQ: DGNX) and continues to operate as a distinct product within the Diginex sustainability solution suite, accessible via its own app.plana.earth login.

Plan A is a European sustainability management platform covering carbon accounting alongside broader ESG work — materiality assessments, strategy and CSRD reporting — and sits in the mid-market band below Watershed and Persefoni. Because it spans more than emissions, quotes reflect which ESG workstreams you activate, not just data volume. Note that the product name collides with ordinary search phrases, so third-party demand figures for it are unreliable. Get an independent shortlist with pricing guidance below.
