Rennie Advisory

The route to zero emissions


Rennie is a sustainability advisory firm helping organisations navigate and optimise their transition to a net zero future. Rapidly growing since launch in 2021, the founding partners recognised the importance of redeveloping their brand to match the sophisticated level of work they were producing for clients, while also creating standout in an ever-expanding sector.


It was clear from our sector analysis and client interviews that Rennie were different in their thinking – transitioning to net zero is not about restricting business but instead opportunity. And so to encapsulate this philosophy, we created a suite of brand messaging that utilised the prefix “re-” meaning to do again in a different way. Pairing this with authentic, contemporary imagery of “business world meets environment”, we had ourselves the perfect brand to represent exactly what Rennie does and that’s redefining sustainable success.
