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.

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 a robust carbon accounting platform that stands out for its certified compliance and scientific rigor. The platform's strengths include its GHG Protocol compliance, TÜV Rheinland certification, and a strong Scientific Advisory Board, which lends credibility to its methodology. The AI-enhanced features, such as automated data collection and reporting, significantly reduce the time and effort required for carbon accounting, as evidenced by claims of 70% faster data management and 20x reporting speed. The platform covers all three scopes of emissions, with specific modules for industries like software, fashion, and fleet management, making it versatile for various sectors. However, Plan A's enterprise focus and opaque pricing are notable limitations. The lack of public pricing makes it inaccessible for smaller businesses that need budget clarity upfront. The platform also requires personalized onboarding and services, which may be a barrier for teams without dedicated sustainability staff. While it offers a Carbon Scanner for quick estimates, the full platform is not self-serve, and you need to schedule a call to get started. Where Plan A shines is in its regulatory compliance support, particularly for CSRD and SBTi, which is critical for enterprises facing stringent reporting requirements. The recent integration with Visa Ready for Fleet is a plus for fleet-heavy businesses, and the acquisition of Diginex could expand its digital measurement capabilities. If you are a large enterprise with the budget and dedicated sustainability resources, Plan A is a solid choice. But if you are a small to mid-sized company looking for transparent pricing and self-service tools, consider alternatives like Watershed or Salesforce Net Zero Cloud, which may offer more accessible entry points.
