If your business falls under scope of the Corporate Sustainability Reporting Directive (CSRD), understanding the European Sustainability Reporting Standards (ESRS) is a must. These are the mandatory guidelines your company must follow to comply with the new directive.

While the framework does wonders for standardizing sustainability reporting and improving transparency across Europe, it’s also extremely complex. With 10 topics, 37 subtopics, and 72 sub-sub-topics—adding up to over 1,100 potential data points to report—getting your head around the ESRS is a significant time investment.

Compliance isn't just time-consuming, it can be expensive too. Audit costs alone are estimated to range between 0.013% and 0.026% of revenue—roughly €13,000 to €26,000 annually for every €10 million in revenue. That, paired with penalties for non-compliance reaching up to €10 million in Germany, getting it right is crucial.

Despite the high stakes, 55% of finance executives still admit to relying on outdated methods like spreadsheets to manage environmental, social, and governance (ESG) data. But with data quality reportedly the biggest barrier to ESG investing, it's clear that legacy technology is failing to keep up with today’s stringent reporting requirements.

That’s why many forward-thinking businesses are turning to specialized ESRS software tools to take some of the burden off their shoulders. These platforms automate complex tasks, ensure compliance, and help to keep costs in check. 

In this article, we’ll explore the top five ESRS software tools currently available to help you determine the best fit for your business. You’ll get to know the ins and outs of:

1. Coolset
2. Sweep
3. Position Green
4. Emitwise
5. SmartTrackers

Quick recap: what are the ESRS and why are they important?

The ESRS are the detailed guidelines companies in Europe must follow to comply with the CSRD. Developed by EFRAG, these standards help businesses report on ESG impacts in a standardized way, improving transparency and comparability. 

Covering a broad array of sustainability topics, the ESRS enables companies to provide comprehensive disclosures that are crucial for investors, customers, and regulators to make informed decisions.

Below is an overview of the ESRS’s ten topical standards covering ESG topics, as well as two cross-cutting standards covering general requirements and disclosures, applicable to all CSRD-affected companies.
