“Selecting the right EcoVadis consultant isn’t just about ticking boxes, it’s about building a partnership that drives real, measurable impact for your business.” 

EcoVadis ratings have become the global benchmark for sustainability performance and companies are under increasing pressure to improve their scores to win business and meet stakeholder expectations. However, navigating this process, and achieving top scores, is complex and requires specialised expertise. Therefore, choosing the right EcoVadis consultant is critical to your success.   

Do it yourself or work with a consultant? 

Some companies work on their assessments without the help of consultants which is possible with a dedicated team and significant institutional knowledge on EcoVadis. However, there are many benefits to working with consultants. For example:   

Expert guidance: Navigate the EcoVadis assessment process efficiently.  

  • Score improvement: Identify and close gaps to achieve higher ratings (Gold/Platinum).  
  • Time savings: Streamline documentation and evidence collection.  
  • Competitive advantage: Stand out to customers and partners with strong sustainability credentials. 

EcoVadis is a very useful tool, however, like all tools, it is must effective when utilised by experts (such as consultants).  

How to choose the right consultant 

Once you have made the decision to hire a consultant, the choices can be daunting. With more players in the field than before, picking the right consultancy is increasingly difficult. The first place to start is in the official directory of EcoVadis’s training partners. This is the most authoritative source for finding the right consultant for your needs. EcoVadis’ training partners are defined as ‘strategic’ and ‘approved’ with ‘strategic’ denoting partners that have followed a rigorous selection process that work collaboratively with EcoVadis.  

We recommend examining the following criteria when selecting a consultant: 

  • Accreditation: Ensure the consultant is an Approved Partner (Strategic Partner is best).  
  • Track record: Look for proven success in helping clients achieve high EcoVadis scores (Gold/Platinum).  
  • Service offering: Match their services (gap analysis, implementation, training) to your company’s needs.  
  • Geographical expertise: Some partners have specific expertise in local regulations and supply chain requirements.
