CARBON | CONSERVATION | CLIMATE | COMMUNITY
“Ecosystems across the world need urgent protection and restoration. Local communities across the world need to urgently adapt to adverse impacts of climate change. Carbon dioxide needs to be rapidly removed from the atmosphere. C4 is catalysing land-use change and societal change at an unprecedented scale to manage all three of these planetary needs.” ~ Anthony Mills
Climate change is impacting people and ecosystems around the world
C4 EcoSolutions is an environmental consultancy that works with communities and governments globally, helping them adapt to these challenges. Coastal surges, floods, increasing droughts, and diminishing agricultural production are just some of the impacts of climate change.
Our work addresses these by focusing on two primary strategies: adaptation and mitigation. Rigorous scientific research underpins all our projects and operations.
