Small Steps, Big Impact: Leveraging Double Materiality for SME ESG Reporting

As global concerns for corporate sustainability continue to gain momentum, regulatory frameworks are evolving to ensure businesses align with environmental, social and governance (ESG) principles. One such development is the Corporate Sustainability Reporting Directive (CSRD), set to impact companies across Europe.  

The CSRD creates a new era of transparency and accountability, introducing enhanced reporting requirements on sustainability matters for large EU companies (MNEs), listed SMEs and non-EU companies with significant activities in the EU. Besides the direct consequences for companies directly in scope, the CSRD will also indirectly impact SMEs through requests for sustainability information from business partners that need to comply and will have to report on their value chain, as mandated by CSRD. Other stakeholders that might request information from SMEs include banks, employees and customers. 

To answer this growing pressure from stakeholders, even SMEs that are not under scope of the legislation can choose to publish a voluntary ESG reporting. By doing this, they can build trust with their stakeholders and show accountability, while also gaining direct economic benefits. Concrete examples are more beneficial interest rates when applying for loans at a bank, being able to apply for (public) grants and winning tenders with customers who are looking for sustainable suppliers. 

However, while larger corporations may have the resources to adapt swiftly, SMEs often face unique challenges when tackling ESG reporting. 

MNEs and SMEs currently have different levels of ESG maturity:

A recent study from BDO Belgium and Mercuri Urval shows that: 



Fewer SMEs already have a sustainability strategy.






Fewer SMEs already disclose information on sustainability.  





Fewer SMEs already have KPIs in place to measure their ESG performance.

It is clear that larger companies are more mature regarding ESG than SMEs. Part of this gap is explained by the fact that they had no legislative requirement to report on ESG matters. The CSRD has reshaped the ESG reporting landscape and has created demands for greater transparency and also accelerates the need for organisational maturity among SMEs.

The starting blocks to embrace ESG transparency

To help SMEs in their disclosure of ESG information, VBO FEB, Agoria and BDO Belgium developed guidelines on how to start your sustainability reporting (available here). 

Here are 5 tips to kickstart your ESG reporting journey: 

  • Define your priorities (double materiality): Find your way throughout the ESG landscape by figuring out where your focus should be from the start. 

  • Dedicate enough resources (time and HR): Especially in the beginning, a large time investment will be needed to set up the reporting. It is definitely not a one person job! 

  • See it as an opportunity: Benefits include being able to transform your organisation into a future-proof business, access to capital, war for talent and cultivating innovation. 

  • Develop targets and allocate responsibilityKnow the targets you are working towards and who will make it happen by means of an action plan (who, why, what, by when). 

  • Be pragmatic and learn from your experienceThe first report will not be perfect, it is a learning curve! 

The double materiality assessment: a key step to define your priorities 

A key aspect of the CSRD is the introduction of the double materiality assessment. This involves evaluating both the financial impacts of sustainability issues on the business and the impacts of the business on society and the environment. This comprehensive approach ensures that companies not only consider the risks and opportunities directly affecting their financial performance but also understand their broader societal and environmental impacts. 

For SMEs, understanding and implementing double materiality assessments can be daunting. However, with BDO's guidance and expertise, these assessments can become invaluable tools for driving sustainable business practices while meeting regulatory requirements.

To shed light on crucial aspects of the double-materiality assessment, we recently participated in a webinar organised by the Verbond der Belgische Ondernemingen (VBO)/Fédération des Entreprises de Belgique (FEB). During the webinar our experts explained what this assessment entails, how it is conducted and its significance, particularly for SMEs.
