The Species Threat Abatement and Restoration Metric (STAR) allows quantification of the potential contributions that species threat abatement and restoration activities offer towards reducing extinction risk across the world.
STAR can inform decisions made by businesses, governments, civil society, and other actors towards global goals for halting extinctions. As such, STAR helps identify actions that have the potential to bring benefits for threatened species, and it supports the establishment of science-based targets for species biodiversity, and commitments relevant to the post-2020 biodiversity framework.
STAR is calculated from data on the distribution, threats, and extinction risk of threatened species derived from the IUCN Red List of Threatened Species™.
STAR is simple to use and interpret as the analysis is carried out automatically in IBAT. STAR insights can be gained by using IBAT site-specific reports, which calculate estimated STAR values for a given Area of Interest, as well as by using IBAT Multi-site Reports to gain a broad understanding at the portfolio/supply chain level. Additionally, the raw raster layer is available to download at the global level and at local scale with 5km granularity.
STAR is standardised across the globe as every grid cell can be directly compared using the same objective criteria. STAR is also scalable as users can sum their potential contributions across sites, regions and countries throughout the world to determine their overall opportunities for nature-positive action.
IBAT has produced an Industry Briefing Note on STAR. For more information on the calculation and interpretation of STAR, please refer to IBAT’s Business User Guidance.
The scientific publication behind STAR in Nature Ecology & Evolution was the result of collaboration by more than 50 organisations around the world and is freely available to access: Mair et al., 2021
STAR is now available through STAR Beta – a free, time limited early access programme. After creating an IBAT account, signup for STAR Beta through the IBAT Dashboard to receive 30 free bespoke STAR Reports.

A new global metric to support nature-positive action. Designed to be simple, standardised and scalable, STAR quantifies the contribution of operating at specific locations to reduce the threat of species extinction risk. Based on the number of species, their extinction risk and their population, STAR Scores can be aggregated between sites - especially with IBAT's Multi-site Report.
