What makes us different
Senior experts stay with you through delivery
You work directly with the specialists who scope your project. They stay involved through delivery, bringing first-hand experience of running sustainability programmes and helping teams turn group priorities into day-to-day work.
We build our own technology
We built Flagship Platform to cut the time clients and consultants spend chasing data across spreadsheets and emails. We keep improving our tools as AI develops, using it where it can reduce manual work, such as screening environmental claims for expert review.
We keep projects clear and on track
At the start, we agree what success looks like, who is responsible for each part of the project and when we’ll review progress together. Our ISO 9001-certified quality management system builds checks into delivery so you can see what’s on track and where your input is needed.
We hold ourselves to the standards we talk about
We’ve been a Certified B Corp since 2023. We use the B Corp standards to assess how we run Flagship, from how we support our team to how we manage our environmental impact, and identify where we can improve.
