ESG accounting & auditing

What is ESG accounting?

ESG accounting is the practice of measuring, analysing and auditing a company’s environmental, social and governance (ESG) impacts and the financial value created, or at risk, in line with International Auditing Standards (ISAE 3000).

Accounting Standards

Omnevue is a purpose built, first-of-its-kind platform that automates ESG accounting in line with International Auditing Standards (ISAE 3000). Our ESG Audits and Value & Risk Accounts are supervised and signed-off by Certified Public Accountants and comply with six standards:


Ensure the ESG inventory appropriately reflects the ESG impacts of the company and serves the decision-making needs of users – both internal and external to the company.

Double Materiality

In ESG accounting, information has a ‘double materiality’ i.e. it is two-way. ESG information is material and should be disclosed when ESG issues (e.g. transition to net-zero) impact the company and also when the company impacts the environment (e.g. CO2e emissions) and society (e.g. gender pay gap).


Account for and report on all significant ESG data sources and activities within the Omnevue Scorecard and any additional measures selected. Disclose and justify any specific exclusions.


Use consistent methodologies to allow for meaningful comparisons of ESG impacts over time. Transparently document any changes to the data, inventory boundary, methods, or any other relevant factors in the time series.


Address all relevant issues in a factual and coherent manner, based on a clear audit trail. Disclose any relevant assumptions and make appropriate references to the accounting and calculation methodologies and data sources used.


Ensure that the quantification of ESG impacts is systematically neither over nor under actual emissions, as far as can be judged, and that uncertainties are reduced as far as practicable. Achieve sufficient accuracy to enable users to make decisions with reasonable assurance as to the integrity of the reported information.

Omnevue Auditors

All Omnevue Auditors are Certified Public Accountants or Chartered Accountants (also certified in ESG). They are the only professionals licensed to independently audit ESG data and impacts and the financial value created, or at risk, in line with International Auditing Standards (ISAE 3000).

Omnevue clients can be confident that their ESG accounting complies with professional standards, applicable laws and regulations, and the Code of Ethics of the Institute of Chartered Accountants of England and Wales.

Omnevue Auditors are professionally committed to uphold the Code of Ethics of the Institute of Chartered Accountants of England and Wales (or equivalent nationally regulated and recognised professional accounting body). This code requires them individually to conduct ESG accounting in line with the following six principles:


Behave with integrity (which implies honesty, fair dealing and truthfulness) in all professional and business relationships.


Maintain professional knowledge and skill at the level required to ensure that work is performed diligently and in accordance with applicable technical and professional standards. This ensures that clients’ data will always be compliant as regulations evolve.


Be objective in all professional and business judgements and to maintain an attitude of professional scepticism. An independent audit is the most convincing way to prove to your stakeholders that you are not greenwashing (intentionally or unintentionally).


Respect the confidentiality of information acquired as a result of professional work and not disclose any such information unless there is a legal or professional right or duty to disclose nor use it for personal advantage.


Only accept or perform work which the member or firm is competent to do unless outside help is obtained. Omnevue is an ESG accounting platform. It does not provide ESG advisory services.


Behave professionally by complying with relevant laws and regulations, avoiding any action that may bring discredit to the profession and behave with courtesy and consideration towards all.

The straightforward answer is, “very differently and very confusingly”. There is a confusion of ESG standards, principles, frameworks, ratings and scores.
