A report from the United Nations Environment Programme (UNEP) evaluated global progress since its biodiversity report in 2020. Two years ago, 196 countries signed a historic treaty to protect biodiversity on 30% of the planet by 2030.

The biodiversity summit underway in Cali, Colombia is a follow-up to the 2022 accord in Montreal, which includes 23 measures to halt and reverse nature loss. One calls for putting 30% of the planet and 30% of degraded ecosystems under protection by 2030.
