ESRS: A beginner's guide to the EU's sustainability reporting standards.

We have exactly 25 years to reach the goal of becoming net zero by 2050. That means efforts to assess, target, and reduce emissions must be ramped up. The European Union (EU) has released a comprehensive environmental, social, and governance (ESG) reporting framework called the European Sustainability Reporting Standards or ESRS. These standards provide the framework for implementing the Corporate Sustainability Reporting Directive (CSRD). Yes, lots of abbreviations there!
CSRD, and by extension, the ESRS, have completely changed the ESG reporting. The directive now impacts even more companies than its predecessor. And the standards cover more ground in terms of the environmental and social impact of businesses operating in the EU block.
This guide will cover the ESRS thoroughly to help you understand what the standards cover and how to go about reporting. The actual document is well over 250 pages, so consider this a succinct summary of the main takeaways.
What is ESRS?
ESRS provides the framework for reporting ESG data, as per the CSRD, which impacts nearly 50,000 companies in the EU. It was developed by the European Financial Reporting Advisory Group (EFRAG) and consists of 12 standards divided into four categories: general, environmental, social, and governance.
The purpose of this framework is to provide guidelines for enterprises on what data to report and how to report it. It standardises and streamlines reporting for all affected entities so that the data is comprehensive, verifiable, and comparable.
At the moment, ESRS guidelines aren’t specific to a sector, so they can be used by any company from any industry. As for the geographic scope, ESRS is primarily for EU businesses, but non-EU businesses with operations in the EU may also need to follow the standards for reporting in the later stages of CSRD’s implementation. So, in essence, ESRS standards are far-reaching.
Double materiality assessment
According to the CSRD, double materiality is a key condition for reporting. It forms the basis of the actual reporting, i.e., what needs to be reported.
Companies must perform a double materiality assessment to determine which standards to use for reporting. In other words, businesses must only report on standards relevant to them.
Double materiality involves assessing the impact of sustainability issues on the company’s financial performance as well as the impact of the company on the environment and society. EFRAG has also published guidelines on materiality assessment to accompany the official ESRS documents.
ESRS reporting framework
Here are the 12 standards that make up the ESRS:

Sector-specific ESRS
EFRAG, on behalf of the European Commission, is also working on sector-specific disclosure standards to provide more detailed and relevant reporting guidelines to companies in certain industries. So far, EFRAG has been directed to focus on the sector-agnostic ESRS, which applies to all reporting companies.
The Commission has delayed the work on sector-specific ESRS by two years. So, companies must only focus on the 12 ESRS standards, the two cross-sectional ones, and whichever other are material to them.
EFRAG is working on creating sector-specific standards for industries like mining, oil and gas, transportation, and finance. It’s clear that these disclosures will primarily target industries with high reliance on fossil fuels and a big carbon footprint.
ESRS for SMEs
EU’s new reporting regulations don’t spare some SMEs either. That’s why EFRAG has also been tasked with creating a simplified ESRS framework for SMEs impacted by the CSRD.
As of the writing of this guide, affected SMEs (which includes listed SMEs, small banks, and captive insurers) aren’t required to follow ESRS. They will follow the SME ESRS guidelines once they’re finalised after a thorough draft review and approval process.
In addition to the LSMEs required to report as per the directive, EFRAG is also working on a voluntary standard for SMEs not covered under CSRD. These standards can be followed voluntarily and are supposed to encourage SMEs to start reporting. They can also benefit them by reporting requirements from other entities like banks or partners.

How to report using ESRS?
Your organisation can create reports using the guidelines from the official ESRS documents published on the EFRAG website. It’s best first to familiarise yourself with the ESRS, particularly the cross-cutting standards as those are required to be followed by all companies.
Here’s a step-by-step guide to ESRS reporting:
1. Conduct materiality assessment
The first step is to complete a double materiality assessment for your organisation following the guidelines from EFRAG (Implementation Guidance or IG 1). This assessment will help you determine which topical standards to consider and include in your annual report.
This process involves engaging with stakeholders and analysing operations, products, and relations. Identify impacts, risks, and opportunities (IROs) for both sustainability impacts on your business and your business’s impact on the environment and society.
2. Conduct value chain assessment
The next step is to understand and assess your value chain in line with EFRAG’s implementation guidance IG 2. It will help you determine your upstream and downstream value chains and how they will impact your reporting. For example, if parts of your value chain are impacting biodiversity, it would be material for you to report using the ESRS E4 standard.
3. Identify material topics and data points
Based on the assessments above, identify the material topics that you’ll report on. This is important because you’ll need to read and understand the guidance for the corresponding topics and report on the specific data points for that topic. There are over 1,100 data points listed by EFRAG for all standards. You don’t have to collect and report data for all – only the general ones and the topics that are material to your organisation.
4. Collect data
Start gathering data for the general disclosures as well as topic-related disclosures based on the listed data points. Engage with stakeholders, partners, suppliers, and consumers to collect relevant data.
Utilise ESG software to collect, organise, and verify data. For instance, comundo can help organisations gather energy data from their real estate assets (offices, facilities, investment properties, etc.). Some solutions may directly comply with ESRS to make data reporting easy. Determine if there are any data gaps and how they may be resolved.
5. Draft report (General standards)
Create a separate section that covers general requirements and disclosures (ESRS 1 and 2). These two cross-cutting standards apply to all entities, so will be covered in all reporting.
ESRS 1 simply sets the general requirements to clarify concepts and principles. And those requirements must be followed throughout the reporting. It’s ESRS 2 that covers the bulk of the data reporting (general disclosures). It includes four areas: IROs, governance, strategy, and metrics and targets.
6. Draft report (Topic standards)
Create a separate section in your report for each of the material topic standards. In theory, you may have reported some of this data in general disclosures, but the data points in topic standards take a deeper dive into the relevant category. Again, use dedicated ESG tools to compile data for the corresponding data points and create the report.
7. Validate data
Once the report is compiled and all the data has been included, validate it to ensure accuracy. You may work with professionals to validate your reporting.
Potential challenges with ESRS
ESRS is relatively new and quite comprehensive. Companies using it for the first time may run into issues. Here are some challenges and potential solutions:
Data collection
Of course, the biggest challenge in ESG reporting is collecting accurate and complete data. ESRS standards like ESRS E1 require reporting on value chain emissions, which can be challenging to find.
Engaging stakeholders in the value chain, collecting data from them, and using powerful tools to automate this process can make data collection much more straightforward.
Training
Companies may need to provide training to their personnel for working with ESG and carbon accounting tools. They may also need to educate employees about ESRS, especially if they’re not directly involved in ESG reporting. Although it would be an investment, hiring ESG professionals to conduct workshops can start the ESRS reporting on the right foot.
Costs
CSRD and ESRS reporting will require businesses in the EU to invest resources to comply. Depending on the size and complexity of the companies, the cost may be significant.
This upfront cost may be sizeable, but it’s simply non-negotiable because compliance is mandatory. However, if done right, this report can help businesses cut down on costs and explore new revenue opportunities.
Prepare and conquer
Implementing CSRS and ESRS is phased, which means not all companies may have to comply immediately. Still, it’s better to prepare in advance and be ready to file your ESG report.
Take the time to read the official documentation. Invest in the best ESG solutions that help you gather and organise data according to the requirements. Work with ESG professionals to prepare and validate your reports. That will prevent any hiccups and ensure that your report meets the standards.
FAQs
What is the difference between CSRD and ESRS?
Corporate Sustainability Reporting Directive (CSRD) is legislation adopted by the EU to make ESG reporting mandatory for large listed and non-listed companies operating in the region. ESRS, on the other hand, is the guiding framework that helps companies comply with the directive.
Who created ESRS?
The European Financial Reporting Advisory Group (EFRAG) created the ESRS drafts after consultations with stakeholders, on behalf of the European Commission.
Who does ESRS apply to?
ESRS standards must be followed by large companies that must report ESG data as per the CSRD. ESRS doesn’t apply to SMEs. Those companies will have their simplified version of ESRS standards.
What is the function of ESRS?
ESRS are a group of 12 standards that provide guidelines for reporting ESG data for companies in the EU impacted by the CSRD. It sets the requirements and presents data points for general and topical disclosures.
Does ESRS require scope 3?
ESRS requires companies to report Scope 3 data as part of its ESRS E1 standard (Climate Change). It references the GHG Protocol for reporting emissions data, including value chain emissions. Only companies that determine that the E1 standard is material to their organisation must report (which is the majority).
