The IUCN (International Union for the Conservation of Nature) estimates that 150-200 species become extinct each day. That's around 64,000 species a year. The Planetary Boundaries Framework proposed that a safe threshold for biodiversity is "limiting extinction" to 10 species per million per year. That’s 87 species a year, given current estimates that there are 8.7million species on planet Earth.
If we think about a safe planetary boundary for biodiversity in terms of a calendar, by 12.30 pm on January 1st we would have crossed the threshold for the number of species becoming extinct.
What can we do improve the situation and, specifically, what can businesses do?
We reviewed the targets being set against the nine Planetary Boundaries by 220 of the world’s largest companies. The study is part of our on-going research into how businesses can translate planetary boundaries to the scale of their organisation.
We also spoke with 38 leading sustainability practitioners, who viewed thresholds associated with biodiversity as one of the most complicated to measure, monitor and evaluate. The key points identified included:
With at least 40% of the world’s economy derived from biological resources, time is running out for ensuring that we remain within our Planetary Boundary for biodiversity.
