Industries such as mining, forestry, and oil and gas have been trying for years to minimise their environmental and social impacts, but there is a growing expectation from civil society, regulators and investors that companies not only ‘do no harm’, but also make a positive contribution to the environment and society.

In many companies, projects follow procedures to avoid or minimise biodiversity impacts and restore biodiversity or offset impacts when these are unavoidable. This framework, known as the mitigation hierarchy, is increasingly used by companies and governments to improve environmental management and contribute to a net positive impact (NPI) or biodiversity net gain (BNG).

Following a NPI commitment by the mining company Rio Tinto, IUCN worked with the company to develop and trial a review protocol that could track its progress towards reaching NPI at an operational level. This protocol was tested at Rio Tinto operations in Australia, Mongolia and Madagascar.
