Sectors we excel in…

We help organisations navigate and optimise the transition to a sustainable future.
Redefining sustainable success.
Rennie advises clients on how to redefine sustainable success in a world of global uncertainty and accelerating policy, regulatory, technological and market change.
Our focus is on the defining transitions of our time — energy, climate, and society. We help shape and navigate the energy transition, drive practical pathways to decarbonisation and sustainability, and support social change that delivers real impact for people and communities.
Rennie bridges the gap between where organisations are today and where they need to be — navigating transition, creating value, and delivering impactful solutions.
Collaboration is central to everything we do.
With a team of experienced, strategic and commercial thinkers, Rennie thrives on delivering quality outcomes for the organisations we work with.
Our diverse expertise, market insights, tenacious problem-solving approach, and collaborative way of working create the platform to make that happen.
