Arm attended previous rounds of the UN talks, and recently worked on research about problematic solutions to plastic pollution.Arm discusses his experience of the negotiations and the influence of industry lobbying, as well as issues around the implementation of policies addressing plastic waste – from bioplastics to recycling.  Further reading:  False solutions unmasking policy gaps in addressing plastic pollution in Thailand and Southeast Asia, Environmental Justice Foundation, 2025 A global treaty to limit plastic pollution is within reach – will countries seize the moment?

• Is green shipping all plain sailing?

  In April, the International Maritime Organisation held the 83rd session of its Environment Protection Committee, where it established a system of penalties and rewards to advance shipping decarbonisation. This follows 2023 industry commitments to reduce emissions by 30% by 2030. Alasdair speaks with Simon Bullock about whether the recent agreement is strong enough to meet climate goals and explores practical actions that can be taken now without relying on greenwashing, expensive infrastructure, or scarce biofuels. Simon Bullock is an interdisciplinary climate change Research Associate at the Tyndall Centre, University of Manchester. He recently completed his doctorate, with his thesis focusing on "Accelerating shipping's climate change transition, and the role of UK shore power. Further reading:  Ten ways to cut shipping’s contribution to climate change, The Conversation, 2021 Update on the latest International Maritime Organization climate meeting, The Conversation, 2025 The need for action now on shipping and climate, Climate Policy, 2025 Click here for our website to read all our most recent Land and Climate Review features and pieces.

• Can U.S. climate science survive under Trump?

  Yesterday, the U.S. Congress approved President Donald Trump's so-called 'Big Beautiful Bill'. This controversial federal budget is set to defund a huge proportion of the nation's climate and environmental science - what will the impacts be for America, and for global efforts against the climate crisis?Bertie spoke to John Holdren, who served as President Barack Obama's Director of the Office of Science and Technology Policy from 2009-2017, becoming the longest-serving Science Advisor to the President in U.S. history. He is now a Research Professor of Environmental Policy at Harvard University's Kennedy School of Government. Further reading: ‘How the G.O.P.

• Colombia versus oil and gas: what’s the truth behind the transition?

  In 2022, Gustavo Petro became the first left-wing candidate to win the Colombian presidential election. During his election campaign, Petro pledged to end the granting of new oil and gas exploration contracts, a commitment his government has so far succeeded in maintaining. This week, Alasdair speaks with third-year doctoral student Guy Edwards who has interviewed over 50 people - from former government ministers to academics and industry representatives - about the impact of Petro’s pledge on Colombia’s energy transition.  Guy and Alasdair discuss what the pledge entails, how it was received by the fossil fuel industry and right-wing media and what will likely become of it following fresh presidential elections next year.    Guy Edwards is a PhD candidate in International Relations at the University of Sussex and a member of the Working Group on Natural Resources, Energy and Climate Obstruction in the Global South of the Climate Social Science Network Further reading: Commentary: The Petro government’s big gamble on ending fossil fuel licensing, University of Sussex, 2025 Climate obstruction in the Global South: Future research trajectories, PLOS Climate Journals, 2023 Supply-side climate policy: A new frontier in climate governance, WIREs Climate Change, 2024  El dilema de Colombia y el mundo: salir de la era fósil o sufrir sus impactos devastadores, Elespectador, 2023 Retrasar la transición energética podría costarle a Colombia 88.000 millones de dólares,  Elespectador, 2023 Click here for our website to read all our most recent Land and Climate Review features and pieces.

• Has neoliberalism undermined climate action?

  Germany's 2025 federal election saw the far-right Alternative für Deutschland (AfD) double its support to 20.8%, becoming the second largest party, while the Green Party fell from 14.8% to 11.6%. The AfD denies climate science and opposes environmental policies on economic grounds. This week, Alasdair interviews academic Felix Schulz, whose recent research has examined public attitudes toward climate policy across six countries - three in the global north and three in the global south.  The research found that core values – particularly those derived from neoliberalism and free-market ideology – are more effective than socioeconomic factors in indicating how people will respond to climate policies.  Felix and Alasdair discuss how neoliberal thinking has shaped public opinion, why climate policy must integrate social and economic considerations, and how job security concerns in industrial roles affect political support for climate action. Felix Schulz is a postdoctoral research fellow at Lund University researching public opinion and climate policy.  Further reading:  Why focusing on “climate change denial” is counterproductive, 2023,  Proceedings of the National Academy of Sciences People with neoliberal views are less likely to support climate-friendly policies, 2025, The Conversation Public support for climate policies and its ideological predictors across countries of the Global North and Global South, 2025, Ecological Economics Navigating sustainable futures: The role of terminal and instrumental values, 2024, Ecological Economics German elections: why most political parties aren’t talking about the climate crisis, 2025,   The Conversation Click here for our website to read all our most recent Land and Climate Review features and pieces.
