How to Choose the Right Sustainability Consultant

Whilst sustainability is becoming business critical, it's stiill unlikely that you need to invest in a big team of full time sustainability resource. Therefore you probably need the help of a consultant. Whether you're navigating new regulations, cutting carbon emissions, or improving ESG reporting, the right sustainability consultant can make all the difference. But with so many specialists out there, how do you find the right fit for your business? Here’s how to get it right.

1. Define Your Sustainability Needs

Before diving into the search, get clear on what you need help with. Are you looking for someone to develop a full net zero strategy? Help with compliance and reporting? Or do you need a carbon accounting expert? Different consultants have different strengths, so knowing your priorities will help you find the best match.

Key questions to ask yourself:

• What’s the main challenge or opportunity we’re tackling?
• Do we need high-level strategy, technical expertise, or hands-on implementation?
• What’s our budget and timeline?

2. Look for Industry-Specific ExperienceSustainability isn’t one-size-fits-all. A consultant who’s worked with manufacturing companies might not be the best fit for a financial services firm. Look for someone who understands your industry’s specific challenges, regulations, and best practices.Where to check:

• Their past projects and case studies
• Client testimonials
• Industry-specific certifications (e.g., SECR, TCFD, GRI, B Corp)

3. Assess Their Technical Skills and CertificationsSustainability is full of frameworks, reporting standards, and carbon accounting methodologies. Make sure your consultant has the right technical expertise for your needs.Common certifications to look for:

• Carbon accounting: GHG Protocol, ISO 14064
• ESG & reporting: GRI, SASB, TCFD, CDP
• Net Zero & sustainability strategy: SBTi, B Corp Accreditation

4. Check Their Approach and Working StyleSustainability isn’t just about technical knowledge—it’s also about collaboration. Some consultants are hands-on, embedding themselves into your team. Others provide high-level advice and leave execution to you. Make sure their approach fits your company’s culture and capabilities.Questions to ask in a call or meeting:

• How do you typically work with clients?
• Can you provide ongoing support, or is this a one-off engagement?
• How do you ensure recommendations are practical and implementable?

5. Prioritise Credibility and ImpactAnyone can call themselves a sustainability consultant, but the best ones have a track record of delivering real impact. Look for tangible proof of their work.Red flags to watch out for:

• Vague claims without evidence
• No past clients or testimonials
• Overpromising (e.g., “We’ll make you net zero in 6 months”)

6. Use a Trusted Platform

Finding a consultant through word of mouth or LinkedIn can be hit or miss.
