About Us
C4 EcoSolutions is a climate and environmental consultancy dedicated to building resilient ecosystems and communities in a rapidly changing world.
We design and deliver solutions that restore natural environments, protect biodiversity, sustain livelihoods, and strengthen resilience — pushing back the pace of climate change, and ensuring that people and nature can thrive in an ever-changing world.
In 2024, C4 EcoSolutions became part of the TAG Group of global security and resilience consultancies. Climate change acts as an amplifier and reinforcer of multiple global threats, from conflict over dwindling land and water resources to social instability caused by mass migration.
Joining TAG has expanded C4’s ability to connect ecosystem protection and restoration to wider resilience building, ensuring that climate change is at the heart of our clients’ policy, corporate strategy, and community responses.

“Ecosystems across the world need urgent protection and restoration. Local communities need to adapt rapidly to the adverse impacts of climate change. Carbon dioxide needs to be removed from the atmosphere. C4 is catalysing land-use change and societal change at an unprecedented scale to meet all three of these planetary needs.”
— Prof. Anthony Mills, Founder of C4EcoSolutions
