Collaboration Over Competition: Triple Bottom Line Accounting’s Approach to Sustainable Change

At Triple Bottom Line Accounting, sustainability is not a bolt-on service or a passing trend. It is part of how the firm sees the future of the accountancy profession.

Their story shows how Carbon Literacy training for accountants can help strengthen team confidence, reinforce shared purpose and make sustainability feel more practical inside an accountancy firm.

The firm has long believed that the transition to a sustainable, regenerative economy will not be achieved through competition alone. It will depend on collaboration, shared learning, and a profession willing to move faster together.

That shared belief is what first connected Triple Bottom Line Accounting with The Green Accountants.

A shared belief in the role of accountants

Their CEO and founder, Dr Peter Ellington, repeatedly found himself on the same industry panels as Mick Seddon, founder of The Green Accountants. Both were making the same case: accountancy has a critical role to play in the transition to a sustainable economy, and the profession needs to respond with urgency.

From there, the relationship grew around a shared purpose.

For Triple Bottom Line Accounting, what stood out was not just the message, but the practical support being built around it. Sustainability Suite’s Carbon Literacy training for accountants offered something different from generic sustainability training: practical, sector-relevant learning grounded in the realities of the profession.

That mattered.

Building sustainability confidence across the team

Triple Bottom Line Accounting made the decision to put every new starter through the training as part of its onboarding process, while keeping it open to existing team members alongside its own in-house Carbon Literacy sessions.

As Fran Ellington explains:

“Hearing the same message from peers in your own profession lands differently. It reinforces that this isn’t niche or peripheral; it is the direction the whole profession is heading.”

That is the key lesson from Triple Bottom Line Accounting’s story. Even firms that are already deeply committed to sustainability benefit from external voices, peer learning, and sector-specific training that reinforces the importance of action.

For the team, Carbon Literacy has helped make sustainability feel more real, more relevant, and more clearly connected to the standards emerging across the profession.

“I think the most valuable takeaway from working with your team is that hearing the same message from an external voice, while keeping it strictly relevant to the accountancy profession, makes the concepts feel more real for our team. It reinforces that these practices are the industry standard, rather than just an internal initiative.”

Collaboration over competition in practice

Triple Bottom Line Accounting has also continued to contribute to the wider movement. The firm has written articles for the AIA, produced CPD training on sustainability in accounting, delivered client webinars, and regularly contributed to industry-specific panels.

That is what collaboration over competition looks like in practice.

It is not about one firm owning the conversation. It is about more firms helping to move the profession forward, sharing knowledge where possible, and recognising that sustainable change will be stronger if accountants work together rather than in isolation.

As fellow B Corp-aligned businesses, signatories of the Better Business Act, and members of the SME Climate Hub, Triple Bottom Line Accounting and The Green Accountants share more than a philosophy. They share a commitment to making progress, not just making statements.

What other accountancy firms can learn

For Sustainability Suite, this is exactly the kind of relationship the profession needs more of: values-led firms learning from one another, strengthening their teams, and helping sustainability become part of everyday accountancy practice.

Triple Bottom Line Accounting’s story is a reminder that sustainable change is not just about individual firms doing the right thing. It is about building a better profession together.
