What Plan A is

Plan A is a Berlin-based decarbonisation platform founded in 2017, built with a scientific advisory board and third-party certifications including TÜV Rheinland, B Corp and Friend of EFRAG status. The platform emphasizes science-led methodology with measurement tightly coupled to reduction roadmaps. See how Plan A compares to other carbon reporting software for UK companies.

The platform's GHG Protocol methodology is TÜV Rheinland certified, providing independent validation of calculation accuracy. Plan A positions itself as the science-first choice for companies that want carbon accounting integrated with evidence-based decarbonisation planning rather than pure measurement.

Who it's for

Plan A targets companies that want measurement tightly coupled to a science-based reduction roadmap, particularly those prioritizing independently certified methodology over rapid deployment. The platform suits organizations committed to evidence-based decarbonisation rather than compliance-only reporting.

Companies publicly listed on Plan A's website include BMW, KFC, Visa, Alphabet and FlixBus, indicating capability across automotive, food services, financial services, technology and transport sectors. The platform works best for organizations where scientific rigor and reduction planning justify the investment in methodology depth.

Scope 1, 2 & 3 coverage

Plan A covers all three GHG Protocol scopes with TÜV Rheinland certification of the methodology. The platform handles all 15 Scope 3 categories with emphasis on scientific accuracy and reduction potential rather than pure measurement efficiency.

For Scope 3, Plan A's scientific approach means the platform focuses on identifying reduction opportunities alongside measurement, helping companies understand not just their emissions but the science-based pathways to reduce them across the value chain.

UK frameworks support

The platform supports GHG Protocol (TÜV Rheinland certified), CSRD, ISSB-aligned frameworks, and holds B Corp and Friend of EFRAG status. While the platform has EU/CSRD design heritage rather than UK-specific focus, the ISSB alignment means outputs should be compatible with UK SRS requirements.

Plan A's European rather than UK-specific design means SECR optimization receives less focus than in UK-native platforms, though the scientific methodology and TÜV certification provide confidence in data quality for any regulatory framework.

Assurance readiness

Plan A's TÜV Rheinland certification of its GHG Protocol methodology provides independent validation that strengthens assurance readiness. The scientific advisory board approach and B Corp certification add additional credibility to the platform's approach to methodology and governance.

For UK SRS S2 assurance requirements, the independent methodology certification and scientific approach align well with assurance expectations for methodology validation. The platform's emphasis on scientific rigor rather than rapid deployment supports comprehensive audit trail requirements.

Pricing

Plan A offers pricing on application, reflecting its positioning around scientific methodology and reduction planning rather than basic carbon accounting. The TÜV certification and scientific advisory board likely support premium pricing for methodology depth.

The science-led approach suits organizations prioritizing methodology validation and reduction planning over cost minimization, though may exceed budgets for companies seeking basic compliance measurement without decarbonisation strategy integration.

Alternatives to Plan A

For companies considering alternatives to Plan A, key options include:

  • Normative — TÜV SÜD validated platform with independent verification but less decarbonisation focus
  • Greenly — AI-assisted platform with broader accessibility but without independent methodology certification
  • Climatise — UK-first platform for companies prioritising SECR and UK SRS over scientific methodology certification

The choice often depends on whether TÜV certification and scientific methodology justify the investment versus alternatives focused on regulatory compliance or accessibility over scientific rigor. Companies comparing carbon reporting software should consider whether Plan A's science-led approach matches their decarbonisation ambitions.

Verdict

Plan A's strength lies in independently certified methodology and science-based decarbonisation integration for companies committed to evidence-based reduction strategies. The TÜV Rheinland certification and scientific advisory board demonstrate genuine commitment to methodology rigor.

For companies wanting measurement tightly coupled to science-based reduction roadmaps, Plan A provides comprehensive decarbonisation capabilities beyond pure reporting. The independent certifications add confidence in methodology accuracy and governance standards.

However, companies prioritizing UK regulatory focus or seeking rapid deployment over scientific depth may find better fits in platforms designed around compliance efficiency rather than methodology validation. Plan A works best where scientific rigor and reduction planning justify the investment in certification depth.
