In 2004, Professor Thompson published a seminal piece of research in the journal Science in which he coined the term microplastics to describe the microscopic plastic fragments found in our oceans.
Since then, he has been involved in key discoveries demonstrating the global distribution of microplastics – from shorelines to the deep ocean and even the highest slopes of Mount Everest – and the potential for microplastics to transport chemicals to marine life.
He has also examined the use of technology – including washing machine filters and other mechanical devices – to both prevent the flow of plastics into the ocean and to clear the waters of what is there already.
He directly influenced the United Nations Treaty on Plastic Pollution, signed by 175 world leaders in March 2022, and has contributed to UK legislation on single-use carrier bags and the use of microbeads in cosmetics.
Professor Thompson has jointly been awarded the prize with Professor Tamara Galloway OBE, from the University of Exeter, and Professor Penelope Lindeque from Plymouth Marine Laboratory.
They have been collaborating on various initiatives since 2007, and this is the second time in a year that their ongoing collaboration has been recognised through an international accolade, after they received the Volvo Environment Prize 2022.
They also collectively won both the Societal Impact category and overall prize in the Natural Environment Research Council’s 2018 Impact Awards.
