Who checks the sustainability reports?

Sustainability reporting appears on 57 recent papers, but assurance of those reports on far fewer: "ESG assurance" on 6, "external assurance" on 3, and the topic is rising. A global assurance standard took effect in 2026. Does assurance make reported emissions more accurate, and who should provide it?

What prompted this

Since October 2025, 34 papers carry an assurance keyword, 12 of which also carry a sustainability, ESG, CSR, non-financial, carbon or climate keyword: "ESG assurance" appears on 6 papers and "external assurance" on 3. The quarter to September 2026 had 12 assurance papers against about 7 per quarter earlier. "Sustainability reporting" appears on 57 papers.

Questions

  • Do firms whose emissions are assured restate them less often, and are their figures closer to independent estimates?
  • Does it matter whether the assurer is an audit firm or an engineering consultancy, and whether the engagement is limited or reasonable?
  • When assurance becomes mandatory under the EU's reporting directive, do the gaps between firms' claims and their emissions shrink?

Data that could help

Assurance statements attached to sustainability reports, reported emissions (CDP, Refinitiv ESG), independent emission estimates, and restatements.

Next step

Compare year-to-year revisions of reported Scope 1 emissions between firms with and without assurance for 2019–2025.
