Sustainability metrics and disclosures have attracted important consideration globally. But, assurance practices range within the quantity of labor carried out and traders could also be lulled right into a false sense of safety by the phrase “assurance.”
The voluntary nature of sustainability reporting has led to fragmented practices and issues about greenwashing, prompting current regulatory actions such because the European Union (EU) Company Sustainability Reporting Directive (CSRD) and the climate-related disclosure rule for U.S. Securities and Change Fee (SEC) registrants.
Traders and different stakeholders more and more depend on sustainability data for decision-making given the rise of environmental, social, and governance (ESG) issues. Naturally, this has elevated demand for exterior assurance, even within the absence of regulatory necessities. As an illustration, the Middle for Audit High quality famous that in 2021, 320 of the S&P 500 firms voluntarily bought assurance companies for a few of their sustainability data.
Nonetheless, these assurance practices range within the degree of assurance supplied. The 2 frequent ranges are “restricted” and “cheap.” So, what do they cowl, and what units them aside?
Assurance of Sustainability Stories: What’s Lined?
Sustainability reviews cowl a variety of matters, from environmental impacts to worker variety, to governance oversight. They usually talk developments and key takeaways within the type of figures and tables.
Notably, sustainability assurance engagements don’t mechanically cowl all the knowledge disclosed in a sustainability report. To know what’s assured inside a sustainability report, one should confer with the accompanying assurance report. The peace of mind report could also be included within the sustainability report, or it could be accessible by referenced hyperlinks (e.g., on the corporate’s web site).
The peace of mind report ought to explicitly establish what’s topic to assurance. As an illustration, the peace of mind report for the 2023 Sustainability Report of Siemens Healthineers states: “We have now carried out a restricted assurance engagement on the disclosures marked with the [check mark] image (hereafter the “disclosures”) within the Sustainability Report of Siemens Healthineers AG.”

For Siemens Healthineers, the factors are the International Reporting Initiative requirements. For Coca-Cola, the factors are additionally listed within the appendices and embody company-specific manuals. Notably in circumstances just like the Coca-Cola instance, traders are inspired to go to the appendices and decide whether or not the chosen standards appear cheap given company-specific enterprise operations.
Within the absence of particular regulatory necessities, firms can go for both restricted or cheap assurance companies. Restricted assurance and cheap assurance signify completely different ranges of confidence within the accuracy of reported data.
What’s Cheap Assurance?
Cheap assurance is akin to what most traders could also be conversant in from monetary audits. It gives the best degree of assurance. The peace of mind supplier reduces the chance that the sustainability data is materially misstated to a predefined acceptably low degree, although by no means to zero.
Importantly, regardless of being the best type of assurance service supplied, cheap assurance doesn’t present absolute certainty. The peace of mind supplier doesn’t assure that each one potential errors or fraud indicators are detected.
As a result of the peace of mind engagement gives solely “cheap” assurance, the procedures are carried out on a check foundation. Which means the peace of mind supplier attracts samples and makes use of analytics to establish particular transactions or estimates that warrant additional testing.

It additionally consists of gaining an in-depth understanding of the processes utilized by administration to organize the disclosures and testing the accuracy of knowledge processed by data know-how programs and guide spreadsheets.
Lastly, the peace of mind supplier will consider whether or not the procedures recognized any errors or misstatements. To find out whether or not administration must appropriate these errors or misstatements earlier than the publication of the sustainability report, the peace of mind supplier makes use of a predefined materiality threshold, which can or might not be disclosed within the assurance report.
If the overall impact of the recognized errors or misstatements is beneath the predefined materiality threshold, the peace of mind supplier can log off with out further disclosure in regards to the recognized points as a result of they’re deemed lower than materials.
The conclusion in an affordable assurance engagement report is expressed in a optimistic kind, as exemplified by the 2022/2023 ESG Report of GUESS: “Our accountability is to specific an opinion on Administration’s Assertion primarily based on our examination. […] We consider that the proof we obtained is ample and acceptable to offer an affordable foundation for our opinion. […] In our opinion, Administration’s Assertion associated to the Key ESG Metrics and Disclosures as of and for the 12 months ended January 29, 2022, and January 28, 2023, is pretty acknowledged, in all materials respects.”

What’s Restricted Assurance?
In a restricted assurance engagement, the peace of mind supplier nonetheless goals to carry out procedures that cut back the chance that the sustainability data is materially misstated. Nonetheless, the accepted degree of threat of fabric misstatement is increased in comparison with cheap assurance engagements.
The procedures carried out are restricted in nature in comparison with these in cheap assurance engagements. As an illustration, within the 2022 Greenhouse Gasoline (GHG) Emissions Assurance Assertion of Coca-Cola, the peace of mind supplier states: “The procedures we carried out have been primarily based on our skilled judgment. Our evaluate consisted principally of making use of analytical procedures, making inquiries of individuals accountable for the subject material, acquiring an understanding of the information administration programs and processes used to generate, combination, and report the Topic Matter [i.e., selected GHG emission indicators] and performing such different procedures as we thought-about obligatory within the circumstances.”
The conclusion in a restricted assurance engagement report is expressed in a damaging kind. Within the case of Coca-Cola, it reads: “Our accountability is to specific a conclusion on the Topic Matter [i.e., selected GHG emission indicators] primarily based on our evaluate. […] We consider that the evaluate proof obtained is ample and acceptable to offer an affordable foundation for our conclusion. […] Primarily based on our evaluate, we’re not conscious of any materials modifications that ought to be made to the Schedule of Chosen Greenhouse Gasoline Emissions Indicators for the 12 months ended December 31, 2022, for it to be in accordance with the Standards [i.e., Coca-Cola Company’s Carbon Accounting Manual].”
Relying on the peace of mind normal used, the peace of mind supplier will possible use the time period “evaluate” to explain the restricted assurance engagement.
Sustainability Assurance Engagements: Key Takeaways

Many firms go for the decrease degree of assurance as a result of it comes at a decrease value. Cheap assurance engagements contain extra complete procedures and provide a better degree of confidence that any potential materials misstatements will probably be caught and corrected.
A key takeaway is {that a} restricted assurance engagement report states that the peace of mind supplier is “not conscious” of any materials misstatement, whereas an affordable assurance engagement report “affirms” that the knowledge reported is materially appropriate.
To evaluate whether or not and what sustainability assurance engagement is supplied, it is strongly recommended that traders find and skim the peace of mind report back to study (1) which sustainability data is topic to assurance procedures, (2) which standards the sustainability data is evaluated towards, and (3) the extent of assurance supplied.
