Professional Services Firms Inspiring a Higher Standard of Sustainability Communication.

As expectations around sustainability communication rise, professional services firms are leading by example and inspiring their clients to see independent validation and responsible, transparent communication as a mark of leadership and credibility.

As expectations around sustainability communication rise, professional services firms are leading by example and inspiring their clients to see independent validation and responsible, transparent communication as a mark of leadership and credibility.

Across sectors, organisations are navigating a more complex communications landscape. Regulation is evolving. Stakeholders are more informed. Procurement processes increasingly reference ESG performance and evidence. In this environment, how sustainability commitments are communicated is just as important as the commitments themselves.

Professional services firms sit at the centre of this shift. They advise on positioning, shape messaging, prepare campaigns, and guide reporting.

Their influence extends far beyond their own brands. When they adopt clear standards for Transparency, Accountability, Fairness and Honesty, they elevate expectations across every client they support.

Three Charter signatories demonstrate how this leadership translates into impact.

Embedding Credibility from Day One

For Ltt Group, responsible communication is integral to its business model.

Founded to provide flexible, on-demand sustainability expertise, Ltt Group supports organisations that are building capability but may not yet require a full-time sustainability function. Founder Jonathan Wragg has long emphasised that credibility depends on clarity. Ambitious goals are important, but stakeholders need to understand the journey, the milestones, and the next steps.

By becoming a signatory of The Anti-Greenwash Charter, Ltt Group embedded this philosophy formally within its operations. The Charter’s principles now inform onboarding, internal processes, and plans for transparent impact reporting.

Independent validation strengthens the firm’s ability to advise clients with confidence and demonstrates that its own communications meet the standards it encourages others to adopt.

This approach sends a powerful message to clients: responsible communication is not about limiting ambition, but about presenting progress in a way that builds lasting trust.

Turning Responsible Communication into Competitive Advantage

At Hattrick, responsible sustainability communication is positioned as a strategic asset.

The Manchester-based B2B communications agency, led by Malin Cunningham, works with purpose-driven businesses to articulate complex ideas clearly and credibly. Already operating as a certified B Corp, Hattrick chose to join the Charter to further strengthen its communications framework.

The Charter provides a practical tool that informs internal training, campaign development, and client advisory work.

It supports the team in asking for evidence, refining claims, and ensuring proportionality. Rather than creating friction, this structure has enabled more constructive conversations with clients.

Many clients welcome this clarity. Independent recognition reassures them that their messaging has been tested against a defined standard. It transforms sustainability communication from a reputational risk into an opportunity to demonstrate leadership.

Influencing Standards Across a Sector

For Select First, the impact extends across an entire industry.

Specialising in the flooring and interiors sector, Select First observed a growing number of sustainability claims that lacked sufficient clarity or substantiation. By signing the Charter, the agency formalised its commitment to rigorous, evidence-based communication and developed a clear Green Claims Policy.

The Charter’s framework strengthened internal discipline and reinforced the agency’s confidence in challenging vague messaging.

In doing so, Select First has positioned itself as a trusted advisor, helping clients understand that transparent, accountable communication strengthens brand credibility.

Clients increasingly value this leadership. Being able to demonstrate alignment with an independent standard differentiates both agency and client in competitive markets where trust matters.

Leadership Through Independent Validation

What unites these professional services firms is a recognition of influence. Their work shapes how sustainability is communicated across multiple organisations and sectors. When they adopt a clear, independent standard, they inspire clients to do the same.

The Anti-Greenwash Charter complements regulation by providing structured guidance, expert review, and independent recognition. It supports organisations in moving from uncertainty to clarity and from aspiration to accountable communication.

By championing Transparency, Accountability, Fairness and Honesty, agencies and consultancies are showing that responsible communication is not a constraint.

It is a signal of professionalism and leadership.

In doing so, they are not only strengthening their own credibility. They are helping to reshape sustainability communication across industries, creating a culture where independent validation and honest storytelling are recognised as the benchmark for trust.
