• EU BDS implementation is transparently monitored using publicly available tools. • The actions tracker shows progress towards the > 100 actions of the EU BDS. • The dashboard uses a set of indicators to track progress towards its 16 targets. • Scientific input is needed to further identify and/or develop suitable indicators. The European Union's Biodiversity Strategy for 2030 (EU BDS) represents a pivotal step forward in the commitment to protect and restore biodiversity, not only within Europe but also at a global scale. In order to reinforce its implementation, an innovative biodiversity knowledge governance has been established. It includes, among other measures, a progress monitoring system that fosters transparency and can inform corrective action to be taken when progress is being reviewed. In this context, we introduce the official, publicly available, online tools at the core of the EU BDS progress monitoring system: the actions tracker and the dashboard. The actions tracker is specifically designed to track progress on the implementation of the more than a hundred actions stemming from the EU BDS, while the dashboard monitors progress across 16 targets using indicators. However, while the actions tracker is a mature tool, the work on the dashboard is still in progress, as indicators are missing for several targets. New scientific input is needed to propel policy tracking and ensure transparent and data-driven monitoring of the EU BDS targets. With this paper, we invite the scientific community to seize this opportunity to actively participate in the policy monitoring process. [ABSTRACT FROM AUTHOR]

Abstract Humans and wildlife are exposed to an intractably large number of different combinations of chemicals via food, water, air, consumer products, and other media and sources. This raises concerns about their impact on public and environmental health. The risk assessment of chemicals for regulatory purposes mainly relies on the assessment of individual chemicals. If exposure to multiple chemicals is considered in a legislative framework, it is usually limited to chemicals falling within this framework and co-exposure to chemicals that are covered by a different regulatory framework is often neglected. Methodologies and guidance for assessing risks from combined exposure to multiple chemicals have been developed for different regulatory sectors, however, a harmonised, consistent approach for performing mixture risk assessments and management across different regulatory sectors is lacking. At the time of this publication, several EU research projects are running, funded by the current European Research and Innovation Programme Horizon 2020 or the Seventh Framework Programme. They aim at addressing knowledge gaps and developing methodologies to better assess chemical mixtures, by generating and making available internal and external exposure data, developing models for exposure assessment, developing tools for in silico and in vitro effect assessment to be applied in a tiered framework and for grouping of chemicals, as well as developing joint epidemiological-toxicological approaches for mixture risk assessment and for prioritising mixtures of concern. The projects EDC-MixRisk, EuroMix, EUToxRisk, HBM4EU and SOLUTIONS have started an exchange between the consortia, European Commission Services and EU Agencies, in order to identify where new methodologies have become available and where remaining gaps need to be further addressed. This paper maps how the different projects contribute to the data needs and assessment methodologies and identifies remaining challenges to be further addressed for the assessment of chemical mixtures.
