Common questions
What is the difference between Maiven and Persefoni?
Persefoni calculates emissions and produces carbon reports against frameworks. Maiven is upstream of that: it tracks the regulations and policy changes affecting your business globally and analyses what each one means. Persefoni does the carbon numbers; Maiven does the regulatory intelligence.
Should I choose Maiven or Persefoni?
It depends on the question you are trying to answer. If it is "what are our emissions and how do we report them?", Persefoni. If it is "what is changing in regulation and what should we do about it?", Maiven. Many sustainability and compliance teams run both.
Does Maiven cover sustainability and ESG regulation?
Yes, deeply. Maiven covers CSRD, CSDDD, SEC climate rules, ISSB adoption, CBAM, and the wider ESG and sustainability agenda across 200+ jurisdictions. Sustainability is one of our deepest coverage areas.
Can Maiven replace a carbon accounting tool?
No, and we do not try to. Carbon accounting is a specialist discipline that needs proper emissions modelling. Maiven complements carbon platforms by giving the same teams visibility on the regulations that drive what they have to report.
How quickly can a sustainability team get started with Maiven?
Most teams are operational within two weeks. We work with you to set up your business profile (sectors, geographies, ESG topics), agree what is in scope, and configure alerts and workspaces.
