The recent commitment by 175 UN nations to end plastic pollution waste is being hailed as an historic moment and a huge global step in the right direction. Earlier this month, Heads of State, Ministers for the environment and other representatives, including New Zealand, endorsed a resolution at the UN Environment Assembly in Kenya. The aim is to draft a legally-binding treaty by 2024 - to stop the proliferation of plastic. But what does this mean in practice, and what is achievable from this large global commitment?. To discuss the scope of the mandate and what negotiations lie ahead to actually stem and prevent plastic pollution, Kathryn talks to Dr Trisia Farrelly who is on the United Nations Environment Programme's Scientific Advisory Committee and Expert Group and Marine biologist and Senior Scientist at ESR and Dr Olga Pantos. Olga is the co-lead of the MBIE-funded national project 'Aotearoa Impacts and Mitigation of Microplastics'.
