Detailed Review

Plan A is a Berlin-headquartered carbon accounting and decarbonisation platform founded in 2017 by Lubomila Jordanova and Nathan Bonnisseau, with a second office in Paris. Its methodology carries TÜV Rheinland certification and is described by the company as GHG Protocol compliant, and the business also holds B Corp certification and states SOC 2 compliance. Plan A has raised roughly $40M in total funding, including a $27M round in 2023.

The platform's stated emphasis is "decarbonisation-first": alongside Scope 1-3 measurement and sustainability-disclosure reporting, it includes AI-assisted decarbonisation modelling, target-setting and supplier engagement tools meant to turn a carbon footprint into a reduction plan rather than a static disclosure. The company lists clients including BMW, Visa, KFC, Sorare, Alphabet and Mollie on its own site.

Pricing is quote-only, reached through a demo request rather than a published price list. For a buyer whose primary goal is cutting emissions rather than just reporting them, Plan A's certified methodology and reduction tooling are the clearer differentiators against the more reporting-first tools elsewhere in this category.

What Plan A does well

  • TÜV Rheinland certified methodology — independent validation most competitors in this category lack
  • GHG Protocol compliant, B Corp certified and SOC 2 compliant simultaneously
  • Decarbonisation modelling and target-setting go beyond pure measurement and reporting
  • Established client base including major brands (BMW, Visa, KFC per vendor)

Where Plan A falls short

  • No published pricing; quote-only
  • No free tier
  • Operates from two offices (Berlin and Paris), which can make "where exactly is my data processed" less clear-cut than a single-HQ vendor
  • Less scale and office footprint than Position Green

Standout feature. TÜV Rheinland-certified methodology combined with AI-assisted decarbonisation modelling — third-party-validated reduction planning, not just measurement.
