Evaluating a global carbon platform for Nigerian reporting.

Persefoni is capable enterprise software. The question for a Nigerian filer is not whether it is good — it is whether its factor set, report structures and commercial model match the market you file in.

What global enterprise platforms are built around

Enterprise carbon platforms are generally built for a particular customer: a large multinational consolidating emissions across many countries, reporting to US SEC climate rules, the European CSRD, or both, with a sustainability function of some size and a budget denominated in dollars or euros.

For that customer they are excellent. Multi-country consolidation, sophisticated Scope 3 modelling, supplier engagement at scale, audit workflow, integration with enterprise systems — these are real capabilities that take years to build and a Nigerian-focused product will not match them on breadth.

The question is whether breadth is what you need. A single-country filer reporting under one framework is not short of countries. They are short of the right factors, the right report structure, and a data model that understands how their sites actually get power.

What to ask any global vendor

  1. Which Nigerian emission factors ship with the product?Not ‘we can add custom factors’ — that puts the maintenance burden on you and means a revision is your problem to notice. Ask which Nigerian grid and fuel factors are included, where they come from, how often they are updated, and what happens to prior-year calculations when one is revised.
  2. How is on-site diesel generation modelled?The single most important question for a Nigerian site. If generation is a custom field or a manual adjustment rather than a first-class input, every site running a generator will be measured wrongly — and the error is invisible because the arithmetic is clean.
  3. Which report structures does it output natively?Ask specifically for FRC and SEC Nigeria structures. Many platforms output CSRD, US SEC or GRI structures and expect you to remap. That remapping is real work and it recurs every year.
  4. Is DisCo-level granularity supported?Where regional factors are more accurate than a national average, can the platform hold a site-level factor and record why it was chosen? Assurance providers ask for the rationale.
  5. What currency is the licence invoiced in, and can that change?A dollar-denominated licence is a treasury exposure on a compliance tool. Ask whether Naira invoicing is available and get the answer in writing before procurement.
  6. What support hours apply, and where is the team?A support window that opens after your working day ends is workable for most questions and painful during a reporting close.
  7. What is the minimum commitment?Enterprise platforms frequently carry multi-year minimums and implementation fees that are quoted separately. Ask for the total three-year cost, not the annual licence.

Where each fits

A global enterprise platform Emvert
Best for Multinationals consolidating across many countries and frameworks Nigerian entities filing under FRC and SEC Nigeria
Breadth Very wide — many jurisdictions, many frameworks, deep Scope 3 modelling Deliberately narrow — one market, done properly
Nigerian factors Check directly; often added as custom Maintained as the core set, versioned per calculation
Generation handling Check directly; frequently a custom field A first-class input alongside grid draw
Commercial Typically USD or EUR, often multi-year Annual, in Naira

Where a global platform is the better choice

  • You report in several countriesIf you consolidate across multiple jurisdictions with different frameworks, that is exactly what enterprise platforms are built for and we would be the wrong tool.
  • You are subject to CSRD through an EU parentDouble materiality assessment and the full ESRS datapoint set are a different reporting problem, and a platform built for it will serve you better.
  • You need deep supplier engagement at global scaleManaging thousands of suppliers across continents is a specialised capability with years of product investment behind it.
  • Your group has already standardisedIf a parent has selected a platform and mandated it, the cost of a second system usually exceeds the benefit of a better local fit. Push instead for Nigerian factors and generation handling to be configured properly.

Questions

Can we use both?

Some groups do — a global platform for consolidated group reporting and a local system for the Nigerian entity’s own filing and evidence. It works, but it is two systems and two sets of numbers to reconcile. Only worth it where the local filing obligation is substantial in its own right.

What about migrating later?

Ask any vendor, including us, what a full export looks like: figures, calculations, factor versions and evidence documents. If the answer is a CSV of totals, you are buying a system you cannot leave. Ours exports the full dataset including attached evidence.

Is Emvert going to have enterprise features eventually?

Some, where they serve Nigerian filers. Not breadth for its own sake — we would rather be the only platform that handles Nigerian diesel generation properly than the twentieth that handles forty markets shallowly. That is a deliberate position and it has costs; this is one of them.
