Top 5 Apiday alternatives & competitors (2025)

The Corporate Sustainability Reporting Directive (CSRD) aims to improve the quality and consistency of sustainability reporting across Europe, helping businesses build stakeholder trust and create lasting value.

Despite its benefits, these new laws also introduce a heavy workload for businesses. In fact, one sustainability expert estimated that it could take up to 375 hours just to gather the data required for the first set of European Sustainability Reporting Standards (ESRS).

To manage this, many businesses are turning to sustainability management software to ensure compliance and take some of the weight off their shoulders. While Apiday is a popular choice in this space, it’s not the only option out there. 

In this blog post we’ll dive into what Apiday has to offer and introduce five interesting Apiday alternatives that might be a better fit for your company’s sustainability needs.
