Our history, your future
We began as part of Manifest Climate (formerly named Mantle314), founded in 2015 to shine a
light on climate-related risk and opportunity in the construction sector and advance strategies to
thrive. As early movers on the need to engage and empower businesses in their climate and
resilience strategies, we work with forward-thinking organizations across various industries,
including construction, finance, government, and real estate. We educate internal teams on
climate developments, equip them with the tools to identify and manage risks and opportunities
and provide leading solutions and strategies to build corporate resilience against climate
Mantle Developments was spun out of Mantle314 in early 2021 to focus specifically on
supporting the built environment to become climate-smart through carbon management and
resilience design and operation. We are recognized leaders in embodied emissions (scope 3)
management and recognize the importance of bringing a holistic ‘whole-life carbon’ approach
and solutions to the market.
If you are forward-thinking and interested in meaningful, purpose-driven work, helping real-world
decision-makers and influencers engage with and respond to the climate crisis and stay ahead
of the climate curve, we think you’d like it here.
