Sustainability is built, not claimed. The organisations that endure are those built to adapt — stronger systems, smarter operations, long-term resilience.
We draw on deep experience across strategy, reporting, and implementation to help organisations get there. We walk in your shoes to help you navigate complexity, respond to evolving expectations, and build impact that moves the needle.
Sustainability isn’t idealism. It’s preparation for where things are going.
Sustainability strategies can’t be siloed initiatives. Success looks like weaving them into every aspect of an organisation’s operations.
Good decisions are grounded in data, informed by stakeholders, and shaped by material issues that matter most.
We believe complex challenges can be made understandable through structure, thoughtful analysis, and clear communication.
Meaningful change rarely happens overnight. We value progress that is measurable, practical, and built to last.
Adelie was founded at a time when companies in Europe were facing a huge increase in sustainability reporting responsibilities. Complexity and workload were soaring.
With backgrounds in large consultancies, co-founders Ben Berger and Tom Stewart saw not just the scale of the work companies were undertaking, but also the price premium the big firms charged them. They felt strongly that companies shouldn’t be priced out of meeting their ESG responsibilities or doing the right thing because of budget.
They knew there was a better way to run a consultancy, not just for their clients but for their employees as well. They saw an opportunity to shape an environment where people thrive, creating social value for their own workforce. It’s a team built from the bedrock of their own complementary skillsets; Ben with his finely tuned technical know-how and Tom who can inspire and engage.
Their deep experience taught them that helping clients change the way they do business isn’t just good for the planet, it creates value too. Instead of being a bolt-on that comes at a cost, they see sustainability, if brought into the core of a business, as a multiplier.
That’s what Adelie was created to do. Whether you need to meet a reporting requirement or you’re a B Corp with purpose baked in, we help you build a resilient business. One that’s ready for what’s next.

Today the sustainability landscape is rocky. Regulations have been watered down and governments have rowed back. We’re optimistic though, because this uncertainty presents opportunity. Businesses have to take up the baton, and we are already seeing companies across all sectors step up and drive positive change.
