In November, we convened the fifth Perseus User Needs & Impact meeting of 2023, co-chaired by Sage and Icebreaker One. During this meeting, we discussed getting the language right around assurance. We also discussed the proposed Perseus business model.

Meeting summary

It was noted that:

  • Getting the language right around the assurance process and requirements is key:
    • Assurance is critical to the solution for building trust
    • A form of assurance is being, or will likely be, mandated across the market
    • Assurance definitions of ‘limited’ and ‘reasonable’ are materially different
    • Basic requirements: level of documentation of technical backbone; ensuring accuracy in data; completeness checks

It was discussed that:

  • Reflecting on assurance principles, there should be controls, checks and balances built in to the solution (e.g. within automated data flow for standardisation)
  • In terms of the business case and involved parties (SMEs, software applications, banks, WBA etc.), the value of Perseus is in:
    • Helping unlock financial investment
    • Saving resources (time, efficiency)
    • Improving quality and credibility
    • Reducing friction for SMEs
    • Improving Scope 3, Cat 15 reporting on financed emissions
