As Minister of Climate, the Environment, Sustainable Development and Green Deal, Zakia Khattabi is strongly convinced of the need to ensure that the ecological transition is also a just social transition. In all her policies she attaches great importance to the One Health concept; this means acknowledging the crucial link between the health of humans, animals, and our environment. Zakia Khattabi started her political career as a researcher and militant with a passion for the social phenomena, which was decisive for the rest of her career. She became a politician for the Belgian French-speaking Green party ECOLO: first as leader of the Senate fraction (2009), later as a member of the House of Representatives (2014) with a reelection in this Chamber (2019). Her parliamentary work was mainly devoted to the Justice, Interior and Equal Opportunities Committees. In 2015, Zakia Khattabi was elected co-chair of her party, a role she fulfilled for five years before being appointed to her current ministerial position in 2020. During her current mandate, Minister Khattabi has been negotiator for the EU, both on the mitigation work program at the Climate COP27 as well as on targets and goals at the Biodiversity COP15. Zakia Khattabi was born on January 15, 1976, in Brussels. She has a degree in social work.

Prof. Marion Koopmans is director of the Department of Viroscience at Erasmus Medical Centre in The Netherlands, the WHO collaborating centre for Emerging Infectious Diseases, scientific director for Emerging Infectious Diseases of the Netherlands Centre for One Health NCOH and scientific director of the Pandemic and Disaster Preparedness Centre in Rotterdam/Delft The Netherlands. Her research focuses on emerging infections with special emphasis on unravelling pathways of disease emergence and spread at the human animal interface. Creating global networks to fight infectious diseases systematically and on a large scale is a common thread in Koopmans' work. Koopmans coordinates the EU funded consortium VEO, which develops a risk based innovative early warning surveillance in a One Health context, and is deputy coordinator of a recently awarded HERA funded network of centres of excellence for EID research preparedness. In 2021, Koopmans founded the Pandemic and Disaster Preparedness Centre PDPC, a research centre with a focus on the occurrence and prevention of pandemics and climate-related disasters, combining expertise from technical, bio-medical, environmental and social sciences. During the corona crisis in the Netherlands in 2020, Koopmans was a member of the Outbreak Management Team that advised the national government on measures to stop the spread of SARS-CoV-2. This role brought her national prominence, making her partly a "beacon of reliability" but she also faced growing distrust from a vocal minority of opponents of the Dutch national government's corona policy. Koopmans has co-authored more than 700 articles that have been cited more than 40,000 times.
