ESG Assurance Basics

ESG assurance is like a fact-check for sustainability reports. It verifies a company's claims about its environmental, social, and governance practices.

Most assurance providers (94%) use the ISAE 3000 revised standard. The scope covers:

  • Environmental impact (carbon emissions, water use)
  • Social practices (worker rights, community engagement)
  • Governance policies (board diversity, anti-corruption measures)

Who cares about ESG assurance? Here's a quick breakdown:

Group Interest
Investors Accurate data for decisions
Regulators Reporting rule compliance
Customers Proof of sustainability
Employees Ethical workplace confirmation

Companies are under pressure. A 2023 PwC survey found 94% of investors suspect "greenwashing."

ESG reporting rules are getting tougher:

  • EU's CSRD will require ESG assurance for many companies
  • US SEC plans mandatory climate risk reporting from 2024
  • Switzerland's new rules will affect over 3,000 companies (likely after 2028)

More companies are getting ESG assurance. In 2020, 58% of listed companies did, up from 51% in 2019.

"Independent assurance can help build trust with stakeholders and investors. Having 3rd party verification of a company's reports can be seen as a positive sign of the credibility and transparency of their reporting." - Dean Emerick, Curator on Sustainability Issues at ESG The Report

Companies should prepare for both limited and reasonable assurance audits. Limited assurance is less detailed and cheaper, while reasonable assurance involves more testing and site visits.

Types of ESG Assurance

Companies can pick between two main ESG assurance types: limited and reasonable. Each one gives a different level of confidence in ESG reporting accuracy.

Basic Assurance

Limited assurance is the entry-level option. It's less thorough and cheaper than reasonable assurance. Here's what you get:

  • Fewer tests and less evidence gathering
  • More reliance on what management says
  • Less checking of source documents

Most companies go for limited assurance right now. In 2022, 69% of firms got some level of assurance, up from 64% in 2021.

Detailed Assurance

Reasonable assurance digs deeper. It gives you more confidence that your ESG info is on point. It includes:

  • More tests and evidence gathering
  • Better understanding of internal processes
  • Closer look at important stuff

It costs more, but it's becoming a big deal. The EU's new rules (CSRD) will make large companies switch from limited to reasonable assurance within four years.

Assurance Types: Side by Side

Feature Limited Assurance Reasonable Assurance
Testing Less More
Evidence Fewer docs More source checks
Cost Lower Higher
Confidence Moderate High
Statement Negative (no issues found) Positive (looks good)

Companies often mix it up. They might use reasonable assurance for big stuff like climate performance and limited assurance for less critical bits.

"Independent assurance can boost trust with stakeholders and investors. Having someone else check your reports shows you're serious about being open and honest." - Dean Emerick, Curator on Sustainability Issues at ESG The Report

When picking an assurance level, think about:

  • Your budget
  • What investors want
  • How you stack up against competitors
  • What the rules say you need to do

A practice run with auditors can help you figure out which level works best for you.

How to Do ESG Assurance Well

To nail ESG assurance, focus on these five areas:

Good Data Systems

ESG reporting lives and dies by reliable data. Here's what you need:

  • Clear data governance
  • Solid management policies
  • Strong quality standards

Think automated checks to catch errors early. It's all about accuracy and staying compliant.

Following Known Standards

Make your ESG reporting easy to understand:

  • Pick quantifiable, relevant metrics
  • Use frameworks like GRI, SASB, or TCFD
  • Stay on top of new rules (like the EU's CSRD)

Talking to People Early

Get everyone on board from the start:

  • Investors
  • Customers
  • Regulators
  • Your own teams (IT, finance, ops)

Early talks = better alignment with expectations and standards.

Checking Your Own Work

Do internal checks before outside assurance:

  • Set up data approval workflows
  • Run regular internal audits
  • Track progress on key ESG metrics

Spot and fix issues before the external auditors show up.

Using Tech Tools

The right software makes ESG data management a breeze. Look for:

Feature Why It's Important
Data processing power ESG data can get complex
Collaboration tools Teams need to work together
Expert support Help with emissions management and reporting

Two ESG software options:

1. Novata: Customizable platform for private markets.

2. Proof (formerly Proof of Impact): End-to-end solutions for ESG data.

Start small with tech and build up as your ESG program grows.

Common ESG Assurance Problems

ESG assurance isn't easy. Companies face several challenges when verifying their ESG reports. Here are the main issues:

Matching Different Rules

Companies struggle with multiple ESG frameworks like GRI, SASB, and TCFD. It's a juggling act.

"The 'alphabet soup' of reporting frameworks complicates the reporting process for organizations", - KPMG study

Unlike financial reporting's single framework, companies deal with 15-20 for non-financial info.

Deciding What's Important

Picking the right ESG issues is tough. Companies must choose wisely to avoid greenwashing claims.

"Companies often express regret in not fully addressing materiality prior to launching into the data collection process", - Weinreb Group Sustainability Recruiting

Keeping Data Accurate

ESG data is tricky. It's not as straightforward as financial data.

Data Issue Impact
Unit conversion errors Massive misreporting
Lack of standardization Difficult comparisons
Data silos Incomplete reporting

Example: ABB over-reported sulfur emissions by 1,000 times for three years. They used kilotons instead of tons.

Finding Expert Help

ESG assurance experts are scarce. Companies are competing for limited talent.

"Only 29% of companies feel ready for ESG assurance", - Larry Bradley, KPMG

This shortage is pushing 54% of companies to hire externally.

Managing Costs

ESG assurance is expensive in terms of money, time, and resources.

Cost Factor Challenge
Data collection Time-consuming
Expert consultation High prices
Software Necessary but costly

"My team spends endless hours collecting ESG data from across our organization, meanwhile, I am drowning in data requests." - Chief Sustainability Officer, global hotel chain

Despite these hurdles, ESG assurance is crucial. With 77% of institutional investors seeing ESG integration as smart business, tackling these problems is a must.

Steps in ESG Assurance

ESG assurance isn't just a checkbox. It's a deep dive into your company's ESG data and reports. Here's how it works:

Getting Ready

Before you jump in:

  1. Pick your ESG framework(s)
  2. Set up clear documentation
  3. Implement strong internal controls
  4. Train your team on ESG data

"Only 29% of companies feel ready for ESG assurance", - Larry Bradley, KPMG

That's a wake-up call, isn't it?

Checking Data and Documents

This is where the rubber meets the road:

  • Review how you collect ESG data
  • Double-check your reported info
  • Make sure your ESG disclosures are complete

Here's a quick look at some common data issues:

Data Issue Impact
Inconsistent units Misreporting
Lack of standardization Difficult comparisons
Data silos Incomplete reporting

Testing and Confirming

Auditors don't just take your word for it. They:

  • Sample and re-calculate
  • Visit sites and observe
  • Interview key people
  • Cross-check with external sources

Writing the Report

The assurance report spills the beans on:

  • What was covered
  • How they did it
  • What they found
  • How sure they are (limited or reasonable assurance)

Giving Advice

After all that, auditors often:

  • Point out gaps in your ESG reporting
  • Suggest better ways to collect data
  • Recommend how to boost your ESG game

"Companies often express regret in not fully addressing materiality prior to launching into the data collection process", - Weinreb Group Sustainability Recruiting

Don't be one of those companies. Get your ducks in a row before you start.

FAQs

What is reasonable assurance in ESG?

Reasonable assurance in ESG is a deep dive into a company's ESG reporting. It's like putting your ESG processes under a microscope.

What does it look at?

  • How you gather ESG data
  • Your accuracy controls
  • How you manage ESG info overall

It's perfect for companies still finding their feet with ESG reporting.

As of February 2023, reasonable assurance has become a big deal. Why? It gives a fuller picture of your ESG practices than limited assurance.

Here's how they stack up:

Aspect Limited Assurance Reasonable Assurance
Depth Skims the surface Goes deep
Scope Zeroes in on specific areas Covers the whole ESG reporting process
Confidence So-so High
Cost Easier on the wallet Pricier
Time Quicker Takes longer

Here's the thing: Reasonable assurance costs more and takes longer. But it gives you (and others) more confidence in your ESG reporting. That's gold when it comes to winning over investors and stakeholders.

"A reasonable assurance engagement provides insights into the company's processes, controls and general oversight associated with collation of ESG information. This may be particularly valuable for a company that presently lacks confidence in its ESG reporting." - February 27, 2023

Bottom line? If you want to show you're serious about ESG, reasonable assurance is the way to go.
