What is the Living Planet Index?
For two decades, the Living Planet Index (LPI) has provided a measure for changes in biodiversity that has helped inform the global debate on the nature loss crisis.
The LPI tracks almost 32,000 populations of mammals, birds, fish, reptiles and amphibians around the world.
The thousands of individual population trends are brought together to calculate the average percentage change in population sizes using an index (below). The percentage doesn’t represent the number of individual animals lost; instead, it reflects the average change in animal population sizes.
The 2022 global Living Planet Index shows an average 69% fall in monitored vertebrate species populations between 1970 and 2018.
