Plan A

Carbon and ESG management software combining emissions accounting, supplier engagement and CSRD reporting in one platform.

Visit Plan A Alternatives

Plan A is a Berlin-based sustainability platform combining Scope 1, 2 and 3 carbon accounting with a CSRD-aligned double-materiality and reporting module. It calculates emissions from activity and spend data, supports supplier engagement workflows to collect primary supply-chain data, and helps companies set and track progress against science-based targets. Dashboards summarize results for internal stakeholders and external reporting. Plan A targets European mid-market and enterprise companies that need to combine day-to-day carbon accounting with the double-materiality assessments and disclosures required under the EU's Corporate Sustainability Reporting Directive, positioning it alongside Normative and Greenly rather than the largest US-focused enterprise platforms.
