The Amazon is the world's largest rainforest but this crucial carbon sink is facing increased deforestation. Land clearing for mining or agriculture has increased under Brazil's president Jair Bolsanaro. But the world needs the Amazon jungle to keep absorbing carbon if more ambitious climate goals are to be met. Is there a place for the private sector to step in where governments have failed? Vivienne Nunis hears from economist Nat Keohane about a new not-for-profit called Emergent. It acts as a kind of middle man, connecting tropical forests with corporations searching for ways to cancel out their emissions. Can it work? Also on the programme, journalist Karla Mendes explains how many Brazilians feel about the Amazon's plight, while Robert Muggah from the Igarapé Institute tells us companies such as Google have stepped up to help with deforestation mapping, when government agencies had their budgets cut.
