Sustainability metrics and disclosures have attracted important consideration globally. But, assurance practices fluctuate 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 Trade Fee (SEC) registrants.
Buyers and different stakeholders more and more depend on sustainability info for decision-making given the rise of environmental, social, and governance (ESG) concerns. Naturally, this has elevated demand for exterior assurance, even within the absence of regulatory necessities. For example, the Heart for Audit High quality famous that in 2021, 320 of the S&P 500 corporations voluntarily bought assurance providers for a few of their sustainability info.
Nevertheless, these assurance practices fluctuate within the stage of assurance offered. The 2 widespread ranges are “restricted” and “affordable.” So, what do they cowl, and what units them aside?
Assurance of Sustainability Stories: What’s Coated?
Sustainability stories cowl a variety of subjects, from environmental impacts to worker range, 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 grasp what’s assured inside a sustainability report, one should discuss with the accompanying assurance report. The peace of mind report could also be included within the sustainability report, or it might be obtainable by way of referenced hyperlinks (e.g., on the corporate’s web site).
The peace of mind report ought to explicitly determine what’s topic to assurance. For example, the peace of mind report for the 2023 Sustainability Report of Siemens Healthineers states: “We’ve got 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.”
However the assurance statements for Coca-Cola’s 2022 Enterprise and Sustainability Report have appendices itemizing the indications that have been topic to assurance.
The peace of mind report must also disclose the standards towards which the sustainability info is evaluated. For Siemens Healthineers, the standards are the World Reporting Initiative requirements. For Coca-Cola, the standards are additionally listed within the appendices and embrace company-specific manuals. Notably in instances just like the Coca-Cola instance, traders are inspired to go to the appendices and decide whether or not the chosen standards appear affordable given company-specific enterprise operations.
Within the absence of particular regulatory necessities, corporations can go for both restricted or affordable assurance providers. Restricted assurance and affordable assurance characterize totally different ranges of confidence within the accuracy of reported info.
What’s Cheap Assurance?
Cheap assurance is akin to what most traders could also be conversant in from monetary audits. It offers the best stage of assurance. The peace of mind supplier reduces the chance that the sustainability info is materially misstated to a predefined acceptably low stage, although by no means to zero.
Importantly, regardless of being the best type of assurance service supplied, affordable assurance doesn’t present absolute certainty. The peace of mind supplier doesn’t assure that every one doable errors or fraud indicators are detected.
As a result of the peace of mind engagement offers solely “affordable” assurance, the procedures are carried out on a take a look at foundation. Which means the peace of mind supplier attracts samples and makes use of analytics to determine particular transactions or estimates that warrant additional testing.
Testing could contain tracing proof to supporting paperwork, confirming info with third events or authorized suppliers, consulting specialists to confirm the reasonableness of assumptions made in estimates or calculations, and conducting on-site testing. It additionally consists of gaining an in-depth understanding of the processes utilized by administration to arrange the disclosures and testing the accuracy of knowledge processed by info expertise techniques 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 right 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 will 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 inexpensive assurance engagement report is expressed in a constructive kind, as exemplified by the 2022/2023 ESG Report of GUESS: “Our duty is to precise an opinion on Administration’s Assertion primarily based on our examination. […] We imagine that the proof we obtained is adequate and acceptable to supply an inexpensive foundation for our opinion. […] In our opinion, Administration’s Assertion associated to the Key ESG Metrics and Disclosures as of and for the yr ended January 29, 2022, and January 28, 2023, is pretty said, in all materials respects.”
Relying on the peace of mind commonplace used, the peace of mind supplier will probably use the time period “examination” or “audit” to explain the affordable assurance engagement.
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 info is materially misstated. Nevertheless, the accepted stage of threat of fabric misstatement is increased in comparison with affordable assurance engagements.
The procedures carried out are restricted in nature in comparison with these in affordable assurance engagements. For example, within the 2022 Greenhouse Fuel (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 evaluation consisted principally of making use of analytical procedures, making inquiries of individuals chargeable for the subject material, acquiring an understanding of the info administration techniques 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 of essential within the circumstances.”
The conclusion in a restricted assurance engagement report is expressed in a detrimental kind. Within the case of Coca-Cola, it reads: “Our duty is to precise a conclusion on the Topic Matter [i.e., selected GHG emission indicators] primarily based on our evaluation. […] We imagine that the evaluation proof obtained is adequate and acceptable to supply an inexpensive foundation for our conclusion. […] Based mostly on our evaluation, we aren’t conscious of any materials modifications that must be made to the Schedule of Chosen Greenhouse Fuel Emissions Indicators for the yr 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 commonplace used, the peace of mind supplier will probably use the time period “evaluation” to explain the restricted assurance engagement.
Sustainability Assurance Engagements: Key Takeaways

Many corporations go for the decrease stage of assurance as a result of it comes at a decrease price. Cheap assurance engagements contain extra complete procedures and provide the next stage of confidence that any potential materials misstatements might 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 inexpensive assurance engagement report “affirms” that the knowledge reported is materially right.
To evaluate whether or not and what sustainability assurance engagement is offered, it’s endorsed that traders find and browse the peace of mind report back to study (1) which sustainability info is topic to assurance procedures, (2) which standards the sustainability info is evaluated towards, and (3) the extent of assurance offered.
