Nigeria’s First Methane Disclosure Raises Questions Over Data Gaps

What changed

Nigeria has published its first public company-level greenhouse-gas disclosure. An analysis published on 27 October 2026 found repeated emissions figures, incomplete methane reporting and inconsistencies in the list of companies said to have submitted data, raising questions about the reliability of the country’s emissions baseline.

Why it matters

A national emissions baseline is only as useful as the company data behind it. If figures are repeated or methane reporting is incomplete, it becomes harder to tell what Nigerian companies are actually emitting and harder to measure change over time.

The immediate issue is credibility. The disclosure creates a public starting point, but the inconsistencies mean that starting point may need clarification before it can carry much weight. The analysis does not establish why figures were repeated or why the company lists differ, and it does not quantify the missing methane data.
