Nature-based solutions for climate change mitigation

UNEP and IUCN (November 2021)

Analysing scientific literature, the report by UNEP and IUCN finds that nature-based solutions (NbS) can deliver emission reductions and removals of at least 5 gigatons of CO2 per year by 2030, and at least 10 gigatons by 2050 on a conservative basis. The report highlights that this contribution from nature, in addition to the rapid decarbonisation of the global economy, can play a significant role in reaching the Paris Agreement goal of limiting global warming to below 1.5°C. To fulfil this potential, NbS require additional funding and must be implemented according to strict standards.
