Why This Became Real

Sustainability reporting in Nigeria has crossed from a marketing exercise into a regulated filing. The Securities and Exchange Commission directed all public companies and significant public interest capital market operators to submit detailed plans for adopting the IFRS Sustainability Disclosure Standards by 15 October 2026, with mandatory reporting for public interest entities scheduled to commence on 1 January 2028. Alongside that, the FRC now requires registration of firms providing assurance services, explicitly including sustainability assurance.

Read those two facts together and the direction is unmistakable: sustainability numbers will be assured, which means they have to be as defensible as financial numbers. A figure somebody estimated in a spreadsheet the week before publication will not survive that.

The gap between a sustainability report and a sustainability system. Most Nigerian companies that publish a sustainability report today produce it by emailing site managers for numbers, receiving inconsistent spreadsheets, and having a consultant assemble a document. That process cannot be assured, cannot be repeated consistently year on year, and collapses the moment someone asks how a figure was derived. The work between now and 2028 is not writing better narrative. It is building the data collection that makes the narrative defensible.

To be clear on our role: Musskart builds software. We are not auditors, assurance providers or sustainability consultants, and we do not determine what you should disclose or calculate your position for you. Your advisers and assurance provider do that. We build the system that collects the data and evidences it.

What IFRS S1 and S2 Actually Demand of Your Data

The two standards split cleanly. S1 covers general sustainability-related financial disclosures — the governance, strategy, risk management and metrics around any sustainability risk or opportunity that could reasonably affect your prospects. S2 is climate-specific and is where most of the data burden sits.

Emissions, across three scopes

Scope 1 from fuel you burn directly — and in Nigeria that means diesel generators, which for most companies here is the single largest and most awkward line. Scope 2 from purchased electricity, complicated by the fact that grid supply and self-generation mix constantly. Scope 3 from the value chain, which is the hardest and where most organisations start with a partial boundary and say so.

Activity data from every site

Litres of diesel by generator, kilowatt-hours purchased per meter, fleet fuel and distance, refrigerant top-ups, waste by stream and disposal route, water withdrawn and discharged. Collected monthly at source with the supporting document attached, not reconstructed annually from memory and invoices nobody can find.

Emission factors, versioned

Activity data becomes emissions through published factors, and factors change. Every calculation must record which factor version and source was used, so a restated prior year is explainable rather than embarrassing. This is exactly the kind of detail assurance providers test and spreadsheets never capture.

Social and governance metrics

Headcount and diversity, injury and lost-time rates, training hours, community spend, board composition and independence, supplier and human-rights screening, anti-corruption training coverage. Mostly sourced from HR and company secretarial systems, which means integration rather than another form for someone to fill in.

Targets and transition

Baselines, targets, interim milestones and actual performance tracked against them over time, plus the capital and operational actions underpinning any transition plan. A target with no tracked progress is a disclosure risk rather than a credential.

Assurance-ready by construction

Every reported figure traceable to its source records, with who entered it, who reviewed it, what evidence was attached and what changed between draft and final. Restatements handled explicitly with a reason. If a number cannot be walked back to a fuel invoice or a meter reading, it will not survive assurance.

The Nigerian Complications Nobody's Template Handles

International ESG platforms are built around assumptions that do not hold here, and this is where a local build earns its cost.

Generators are your emissions profile

In most countries Scope 1 for a services business is trivial. In Nigeria a bank, hospital or manufacturer runs diesel generators for a large share of operating hours, making Scope 1 material and highly variable. You need per-generator fuel logs, run hours, and ideally a link to the tank or supply records, at every single site. Getting this data honestly is the largest single task in a Nigerian ESG programme.

Grid supply is intermittent and mixed

Scope 2 calculations assume you know how much grid electricity you consumed. With band-based supply, estate sub-metering and constant switching between grid, generator and increasingly solar, you need metering data good enough to attribute consumption to a source. Where the site sits behind an estate's sub-meter, that adds another layer — see estate utility billing.

Many sites, weak connectivity

Branches, depots, plants and outlets, some with poor internet and none with a dedicated sustainability officer. Data capture has to work on a phone, offline, in under two minutes, by someone whose actual job is something else. If it does not, the data simply will not arrive and you will be back to estimating.

Supply chain data barely exists

Scope 3 depends on suppliers giving you data most Nigerian suppliers do not have. The realistic approach is a defined and disclosed boundary, spend-based estimation where primary data is unavailable, and a supplier engagement programme that improves coverage year on year. Be honest about the boundary rather than producing a confident number you cannot defend.

Cost, Timeline and Sequencing

Data collection core

₦9,000,000 – ₦15,000,000

Site and asset register, mobile offline data capture with evidence attachment, emission factor library with versioning, Scope 1 and 2 calculation, review and approval workflow, and a consolidated dashboard. Three to five months.

Full disclosure platform

₦16,000,000 – ₦23,000,000

Adds social and governance metrics with HR and company secretarial integration, partial Scope 3 with supplier portal, targets and transition tracking, disclosure mapping to the standards, restatement handling and the assurance evidence pack. Five to nine months.

Group / multi-entity

₦23,000,000 – ₦28,000,000

Several entities and jurisdictions, consolidation with intra-group elimination, per-entity and group disclosure, and alignment with your ICFR evidence library so both assessments share one control environment. Eight to twelve months.

Start collecting before you decide what to disclose. The single most useful thing you can do this year is begin capturing monthly diesel, electricity, fleet and waste data at every site with evidence attached. That data has a twelve-month lead time you cannot compress — you cannot go back in January 2028 and collect 2027's generator logs. Everything else, including the disclosure decisions, can be settled later with your advisers.

If you are also handling the FRC's internal control obligation, build the two on one evidence library rather than separately — see ICFR software. The review, approval and evidence discipline is identical and doing it twice is pure waste.

The Securities and Exchange Commission directed all public companies and significant public interest capital market operators to submit detailed plans for adopting the IFRS Sustainability Disclosure Standards by 15 October 2026, with mandatory reporting for public interest entities scheduled to commence on 1 January 2028. Alongside that, the Financial Reporting Council now requires registration of firms providing assurance services, explicitly including sustainability assurance. Read together, those two developments mean sustainability figures will be assured, so they need to be as defensible as financial figures. A number estimated in a spreadsheet the week before publication will not survive that.

Scope 1 emissions from diesel generators, which is the opposite of the position in most countries. For a services business elsewhere, direct emissions are trivial; in Nigeria a bank, hospital or manufacturer runs generators for a large share of operating hours, making Scope 1 material and highly variable. You need per-generator fuel logs and run hours at every site, ideally linked to tank or supply records. Close behind it is Scope 2, because with band-based grid supply, estate sub-metering and constant switching between grid, generator and solar, attributing consumption to a source needs metering data most organisations do not currently capture. Getting this data honestly is the largest single task in a Nigerian ESG programme.

A data collection core with a site and asset register, mobile offline capture with evidence attachment, a versioned emission factor library, Scope 1 and 2 calculation, review and approval workflow and a consolidated dashboard runs 9,000,000 to 15,000,000 Naira over three to five months. A full disclosure platform adding social and governance metrics with HR integration, partial Scope 3 with a supplier portal, targets and transition tracking, disclosure mapping, restatement handling and an assurance evidence pack runs 16,000,000 to 23,000,000 Naira over five to nine months. A group build across several entities with consolidation and alignment to your ICFR evidence library runs 23,000,000 to 28,000,000 Naira.

You can, and for a multinational subsidiary reporting into a group system that is often the right answer. Where they struggle is on the Nigerian specifics. They assume Scope 1 is minor for services businesses, they assume grid electricity consumption is known rather than mixed with self-generation, they assume sites have reliable connectivity and a designated sustainability officer, and they assume suppliers can provide Scope 3 data. None of those hold for most Nigerian operations. A local build handles per-generator fuel logging, source attribution across grid, generator and solar, offline mobile capture by someone whose actual job is something else, and a Scope 3 boundary you disclose honestly rather than guess at.

Start collecting data, before you decide anything about disclosure. The single most valuable action available this year is capturing monthly diesel, electricity, fleet and waste data at every site with the supporting evidence attached. That data has a lead time you cannot compress: you cannot go back in January 2028 and reconstruct 2027's generator logs, and an assurance provider will ask for the underlying records rather than the summary. Everything else, including which disclosures apply to you, how to frame the narrative and where to set your Scope 3 boundary, can be settled later with your advisers once you have a defensible dataset behind you.

Neither. Musskart is a software company, not an audit firm, an assurance provider or a sustainability consultancy. We do not determine what your organisation should disclose, we do not calculate your position on your behalf, and we do not provide any form of assurance over the numbers. Your advisers and your registered assurance provider do that work, and under the FRC's registration requirement for assurance firms that is increasingly a regulated role. What we build is the system underneath: site-level data collection with evidence, a versioned emission factor library so calculations are reproducible, review and approval workflow, consolidation, and the audit trail that lets every reported figure be walked back to a fuel invoice or a meter reading.
