With five and a half years of content, The Land and Climate Podcast has an overwhelmingly large back catalogue. We have always aimed to produce evergreen episodes, however, and many of our older interviews still have insights and relevance in 2026.
This is why we are launching a new offering, alongside our usual programming, called ‘In Review’. Alasdair and Bertie pick one topic per episode, playing highlights from our favourite interviews and discussing recent developments.
First up: plastics.
Following reports that the current draft of the much-delayed UN Plastics Treaty is even less ambitious than the one rejected by many nations last year, Bertie and Alasdair listen to interview excerpts about microplastics, false solutions to plastic waste, and industry lobbying around the Treaty negotiations.
Featuring clips of science journalist Matt Simon, Punyathorn Jeungsmarn (Arm) from Environmental Justice Foundation, and Dr Rob Ralston from The University of Edinburgh.
