How to Hire an ESG Consultant: A Step-by-Step Guide for Companies
Hiring the right ESG (Environmental, Social, and Governance) consultant can make a measurable difference in your company’s sustainability performance. Whether your goals are carbon reduction, improved governance, or investor-ready ESG reporting, this guide provides actionable steps to hire an ESG expert who delivers results. This guide is designed for companies facing increasing ESG requests from investors, clients, or procurement teams—and looking for practical, not theoretical, support.
Step 1: Clarify Your ESG Needs
Before searching for a consultant, clearly define your objectives and what the impetus is for starting this work. Many Green Buoy Consulting clients are getting requests from private equity investors or from clients directly. In 2026, companies remain beholden to investor and client ESG requests, even as public attention on sustainability fluctuates. Understanding the specific request—whether from private equity, customers, or procurement teams—is the first critical step.
Step 2: Determine the Type of Consultant You Need
ESG consultants offer different levels of support. A fractional ESG consultant provides flexible, ongoing guidance without a full-time hire. Specialist consultants focus on areas like carbon accounting, ESG reporting, or stakeholder engagement. Full-service ESG advisors deliver end-to-end strategy and implementation, ideal for larger companies or complex compliance requirements.
Recent Green Buoy clients have leveraged fractional ESG consulting for multi-year engagements, including SASB-aligned ESG strategy development and science-based target planning.
The majority of Green Buoy Consulting clients are looking for consistent support on a monthly basis and someone they can call for both proactive and reactive ESG requests. For example, an annual engagement could cover the following projects:
Completing a carbon footprint
Reviewing RFPs and updating language to align with the current ESG strategy
Submitting a target to Science Based Targets Initiative (SBTi)
Updating a climate strategy to align with SBTi requirements
Completing EcoVadis and/or CDP submissions
Reviewing pitch decks and company collateral to ensure ESG alignment
Meeting with real estate, procurement, legal and other internal teams on ESG requests from their stakeholders
Reviewing and updating policies
Need Ongoing ESG Support?
If your team is fielding regular ESG questions from investors or clients, a fractional ESG consultant can provide consistent, practical support—without a full-time hire.
Step 3: Search Strategically Using Hiring Keywords
Focus your search on keywords that clearly signal hiring intent, such as “hire ESG consultant,” “ESG consulting services for companies,” or “fractional ESG expert for business.” These terms surface providers who are actively offering advisory services rather than general thought leadership. Platforms like LinkedIn, industry-specific professional networks, and ESG consultancy websites are particularly effective for identifying qualified experts, reviewing their experience, and assessing whether their expertise aligns with your business needs.
It’s also worth reaching out to trusted contacts, investors, and industry professionals to see who they’re using for ESG help and how they approach ESG strategy.
Step 4: Evaluate Expertise and Cultural Fit
Evaluate ESG consultants by looking beyond credentials alone. Review their professional experience, educational background, and the types of organizations they have supported. Experience should align with your company’s scale, industry, and operational complexity.
Ask for concrete examples of past work, measurable outcomes, and case studies that demonstrate real impact. Equally important is cultural fit: the right consultant should understand your company’s values, industry context, and pace of decision-making, and be able to work collaboratively with internal teams to drive meaningful progress.
Each company and team has their own unique style, communications and needs. It’s worth highlighting the types of work product, communication style, level of feedback and engagement you’re hoping to have with a consultant.
Step 5: Request a Detailed Proposal
Ask shortlisted consultants for a written proposal outlining deliverables, timeline, and pricing. A strong proposal might include a 12-month ESG roadmap, KPIs, and stakeholder engagement strategies. This ensures transparency and allows you to compare potential consultants effectively.
Step 6: Formalize the Engagement
Once a consultant is selected, create a formal agreement detailing scope, deliverables, milestones, and reporting cadence. Establish regular communication and clear KPIs to track progress. Effective engagement ensures ESG initiatives remain on track and aligned with business objectives.
Step 7: Monitor Progress and Expand
Ongoing monitoring and feedback are essential. Review progress regularly, adjust strategies as needed, and expand the scope over time. For example, consultants can provide guidance on RFP sustainability responses or help prepare for private equity ESG requirements.
