Choosing a sustainability consultancy: Which recognitions matter most? 

When choosing a sustainability consultancy, external validations and independent rankings can be powerful indicators of trust, credibility, and capability. Recognitions demonstrate not only expertise but also accountability, both essential when your organisation’s sustainability journey depends on accurate guidance and verifiable results. What should you look for in a sustainability consultancy?  

Strategic recognition in ESG strategy 

Look for consultancies recognised in independent guides that evaluate firms based on their ability to develop sustainability strategies closely aligned with business goals, regulatory requirements such as CSRD, and stakeholder expectations. These endorsements indicate a consultancy’s strength in creating integrated ESG roadmaps that embed sustainability into core operations, driving enhanced resilience and business performance.  

An example of such an endorsement is the Verdantix Buyer’s Guide for ESG and Sustainability Strategy Services 2025, where Nexio Projects is listed as a leading provider among the evaluated firms, demonstrating expertise in delivering this level of strategic support. 

You can seek high scores in ESG and sustainability strategy excellence, such as: 

• ESG reporting support for frameworks like CSRD, GRI, VSME and more 
• Climate solutions, from decarbonisation roadmaps to product sustainability and climate risk assessments 
• Rating & certifications expertise in EcoVadis, B Corp, CDP and others, guiding continuous improvement 

Additionally, check for strengths in ESG and sustainability digital transformation, including software selection, deployment, implementation, and partnerships, Nexio Projects was highlighted by Verdantix for these capabilities, affirming leadership in ESG advisory.  

Long-lasting expertise 

Seek consultancies with official partnerships, such as strategic training roles with platforms like EcoVadis, where their expertise is directly approved by the platform and further validated through independent assessments that highlight top performers in delivering hands-on guidance for superior sustainability ratings. These endorsements signal a consultancy’s ability to provide precise, actionable support that drives verifiable impact in sustainable practices.  

Nexio Projects, which has a strategic training partnership with EcoVadis since 2018, exemplifies this by is featured in independent lists such as GoodLab’s 10 Best EcoVadis Consultants, and the EUPD Research Top Brand Corporate Sustainability 2025 award.

Proven leadership across industry benchmarks 

Look for consistent placements in rankings signaling deep market knowledge and client results in ESG navigation. Nexio Projects earns a spot in such rankings, namely in like Consultancy.nl’s Best ESG Advisory Firms 2024 and MT Sprout’s SD400 Sustainability Consultancies 2024. This bridges ambitions with execution, from certification support to impact measurement, for strengthened compliance and competitive edges without disruption.  

Championing inclusive workplace culture 

Strong Diversity, Equity, and Inclusion (DEI) commitments are vital in sustainability consultancies because they foster innovation through diverse perspectives, improve decision-making on complex ESG challenges, boost employee engagement and retention, and ensure strategies reflect real-world stakeholder needs for more authentic, impactful sustainability outcomes.  

Certifications from trusted evaluators like Great Place to Work verify these efforts through rigorous metrics. Nexio Projects is Great Place to Work certified and has been recognised as one of the Best Workplaces for Women 2025, meeting criteria such as industry-benchmark women representation, over 33% women in leadership, senior female management presence, and a 70%+ Trust Index from women employees.
