Colin has almost 25 years' experience communicating about the natural world and climate change.

During 15 years at WWF (World Wildlife Fund) he wrote numerous articles and appeared in hundreds of media interviews on topics including renewable energy, tropical rainforests, chemical pollution, ocean biodiversity and sustainable development.

Colin has worked on conservation issues at a senior level around the world. During his career he has led many high-profile campaigns and worked across a number of United Nations climate and biodiversity agendas. He is an agenda contributor for the World Economic Forum on these issues and an advisor for the Earthshot Prize.

In recent years Colin's collaboration with Silverback Films has become his principle focus. He was WWF's Executive Producer for the Our Planet project and the Scientific and Conservation Advisor to the Emmy Award-winning Netflix series Our Planet. He was Executive Producer of the feature documentary David Attenborough: A Life on Our Planet.
Following the success of those projects, Colin and Jonnie Hughes formed Studio Silverback with Alastair Fothergill and Keith Scholey. One of Studio Silverback's first projects is a five-part TV series for the BBC about the Earthshot Prize.
