About Plan A
Plan A is a certified carbon accounting and decarbonisation platform that helps enterprises measure, report, and reduce their carbon footprint. Designed for industries like software & IT, business services, fleet management, media, and fashion, it offers AI-enhanced tools for emissions measurement, ESG reporting, and target setting. The platform is GHG Protocol compliant and TÜV Rheinland certified, ensuring data reliability. Key features include 70% faster data management, 130+ days saved on carbon accounting, and 20x faster reporting. Plan A also provides personalised services and a scientific advisory board to align strategies with the latest standards. It positions itself as a decarbonisation-first solution for forward-thinking companies aiming to turn sustainability into business results. The platform covers Scope 1, 2, and 3 emissions, supplier engagement, fleet emissions, and regulatory compliance (CSRD, SBTi, EU Taxonomy). Recent developments include joining the Visa Ready for Fleet program for automated fleet emissions tracking and acquiring Diginex to expand digital measurement capabilities. A new London office supports UK-based businesses. Compared to alternatives like Watershed or Salesforce Net Zero Cloud, Plan A emphasises certified compliance and scientific rigour, but its enterprise focus and opaque pricing limit appeal for smaller teams.
Behind the Verdict
Plan A is built for enterprises where compliance credibility matters more than cost. Its GHG Protocol and TÜV Rheinland certifications, alongside its Scientific Advisory Board, give it a trust advantage over less formalised platforms. The AI-enhanced data collection and reporting speeds (70% faster data management, 20x reporting) are real time-savers for teams that already have dedicated sustainability staff. The Visa Ready for Fleet integration and Diginex acquisition show a focus on automated fleet and digital measurement — useful for mobility and manufacturing sectors. However, plan A falls short for smaller teams. There's no free tier or transparent pricing on the website, which makes it a poor fit for businesses without a sustainability budget. The platform's heavy reliance on personalised expert guidance means self-service is limited; don't expect an out-of-the-box dashboard you can configure solo. Compared to Watershed, Plan A is more compliance-oriented (CSRD, SBTi, EU Taxonomy) but less plug-and-play with existing data sources. For a mid-market company with sustainability staff and audit requirements, Plan A is a strong pick. For a startup wanting a quick carbon estimate, the free Carbon Scanner is useful, but the full product is overkill.
