IUCN Red List of Threatened Species, Red List Index & Kunming-Montreal Global Biodiversity Framework
The IUCN Red List of Threatened Species is one of the most comprehensive and widely recognized resources for understanding the extinction risks faced by species worldwide. By applying rigorous and quantitative criteria, it categorizes species based on their vulnerability to extinction (IUCN, 2012). Remarkably, as of 2024, it has assessed an impressive 163,040 species, providing invaluable data for conservation planning and policymaking. The list categorizes each into one of nine categories:
- Extinct
- Extinct in the wild
- Critically endangered
- Endangered
- Vulnerable (representing the ‘threatened’ categories)
- Near threatened
- Least concern
- Data deficient
- Not evaluated
Moreover, this categorization reflects the diversity of species’ survival statuses, highlighting the most urgent conservation priorities. Additionally, by offering a global overview, the IUCN Red List identifies biodiversity hotspots and directs actions to mitigate the primary drivers of species decline, such as habitat destruction, climate change, and overexploitation.
The Red List Index: Measuring Biodiversity Health
Derived from the IUCN Red List, the Red List Index (RLI) serves as a key indicator of the overall extinction risk of species groups. This annually updated metric tracks changes in extinction risk over time, offering a snapshot of global biodiversity health (IUCN, 2024).
The RLI is vital for monitoring progress toward international biodiversity goals. It is officially recognized as an indicator for Sustainable Development Goal (SDG) 15.5, which emphasizes the protection of threatened species and the prevention of biodiversity loss (UNSD, 2024). Moreover, the RLI functions as a headline indicator for Goal A of the Kunming-Montreal Global Biodiversity Framework (KMGBF), which underscores its importance in the broader global biodiversity agenda (CBD, 2024).
The Kunming-Montreal Global Biodiversity Framework: A Vision for the Future
Adopted during the Fifteenth Conference of the Parties to the Convention on Biological Diversity (COP15) in December 2022, the Kunming-Montreal Global Biodiversity Framework (KMGBF) represents a monumental step toward safeguarding the planet’s biodiversity (CBD, 2022). This framework aims to halt and reverse biodiversity loss by 2030 through ambitious targets, including restoring degraded ecosystems, reducing species extinction rates, and integrating biodiversity into sustainable development plans.
The KMGBF emphasizes the interdependence of biodiversity, climate resilience, and human well-being. By aligning with indicators such as the RLI, it ensures that biodiversity monitoring is robust and actionable. The framework also promotes international collaboration, recognizing that biodiversity conservation is a shared responsibility requiring coordinated global efforts.
