Living on Earth's journey to the Congo Basin, with Alex Chadwick and Christopher Johnson, continues. Our special report looks at the promises and pitfalls of climate policy, and how REDD might protect the world's second largest forest.

Living on Earth's special report on REDD and the Congo Basin concludes. There's optimism that REDD could help preserve the carbon in the trees and, perhaps, alleviate the poverty of the nation's people.

A program called REDD could be the fastest, least expensive way to stall global warming. REDD is a scheme that aims to reduce greenhouse gas emissions from deforestation by preserving trees. Award-winning correspondent Alex Chadwick and producer Christopher Johnson travel to the Congo Basin to investigate the high stakes of protecting the carbon-rich forest, the wildlife, and people who live there.
