Sustainability compliance can be a real headache, especially for mid-market companies. With limited resources and smaller teams, keeping up with the ever-changing maze of regulations can feel overwhelming. 

Between understanding new laws like the EU's <a href="https://www.coolset.com/academy/csrd-eu-climate-regulation-explained" rel="noopener noreferrer">Corporate Sustainability Reporting Directive (CSRD)</a>, collecting accurate data for emissions reporting, and trying to make sense of voluntary frameworks like the <a href="https://ghgprotocol.org/standards" rel="noopener noreferrer">Greenhouse Gas Protocol (GHGP)</a> or the <a href="https://www.globalreporting.org/standards/" rel="noopener noreferrer">Global Reporting Initiative (GRI) standards</a>, it's a lot to manage. 

Add to that the pressure of ensuring your reports are <a href="https://www.coolset.com/academy/csrd-compliance-audit" rel="noopener noreferrer">audit-ready</a> and the risk of fines or reputational damage from mistakes—it's easy to see why so many businesses feel stretched thin. And without the right tools, much of this work ends up being manual, time consuming, and prone to errors.

That's why many forward-thinking companies are turning to specialized sustainability compliance software to take some of this burden off their shoulders. These tools enhance the accuracy and credibility of sustainability reporting while saving time and fast-tracking compliance.

This article will compare the top five sustainability compliance solutions currently on the market to help you find the right fit for your business, including:

## Quick recap: which sustainability regulations do mid-market companies need to comply with?

Before we dive into the comparison, let's take a quick look at the current sustainability regulation landscape. 

Climate regulations are growing fast across the globe. In fact, according to <a href="https://esgnews.com/global-esg-regulation-increases-by-155-over-the-past-decade/#:~:text=ESG%20Book%2C%20a%20global%20leader,continues%20to%20shape%20financial%20markets." rel="noopener noreferrer">ESG Book</a>, the number of ESG-related regulations has increased by 155% over the past decade, with 1,255 new ESG regulations introduced worldwide between 2011 and 2023. This shows just how important it is for businesses to adapt. 

For mid-market companies, the regulations you must comply with depends on where your business operates. Let's take a look at some notable regulations in key regions around the world:

### EU regulations and standards
