Meet the team
Our Roots
Mantle was co-founded by Ryan Zizzo in 2015. Motivated by his work on some of the country’s greenest buildings and time in Finland, where he “saw the future of sustainability," Ryan set out to apply new approaches in carbon management and life cycle assessment in Canada. In 2021, our technical team became Mantle Developments, focused squarely on decarbonizing the built environment.
Today, we continue that evolution as Mantle Climate.
Where business performance meets climate impact.
