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.

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.

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.

Felix Schulz, a postdoctoral research fellow at Lund University, dives into the intricacies of public opinion on climate policy. He reveals how neoliberal values often overshadow socioeconomic factors in shaping attitudes toward climate action. Discussing the rise of far-right ideologies and their denial of climate science, Schulz emphasizes the need to address job security concerns in traditional industries as they transition to greener practices. The conversation highlights the crucial link between political trust, public beliefs, and effective climate policies for both the Global North and South.

From widespread industrial pollution to emerging as a green powerhouse, China’s economic evolution shows how grassroots activism has pushed ecological issues to the political forefront.  Tianjie and Bertie discuss China’s green evolution, Pan Yue’s introduction of environmental nationalism (now championed by Xi Jinping), flawed provincial reporting, and whether the country’s model can be sustained. Ma Tianjie is a freelance writer and environmental activist based in Beijing. He worked as Greenpeace’s Program Director for Mainland China until 2015, and then as Director of China Dialogue Beijing until 2022. His book, In Search of Green China, was published in February 2025 by Polity Press.

A UK government agency recently announced it would spend £57 million on a controversial project to develop geoengineering technologies.   The Exploring Climate Cooling Programme will fund 21 international research teams to conduct small-scale, controlled outdoor experiments to thicken Arctic sea ice and brighten clouds, to prevent global warming from increasing past irreversible tipping points. Geoengineering has long been a point of contention amongst scientists, environmental academics and conspiracy theorists - each firm in their beliefs about whether such interventions are necessary, effective, or risk irreversibly damaging the planet. Alasdair speaks with two academics studying geoengineering - Albert Van Wijngaarden and Adrian Hindes - who call for nuanced understanding and more productive conversation between the advocates and opposers of such radical interventions. They discuss the history of polar and solar geoengineering, the risks involved, and the lack of global governance. If you enjoyed this episode, stay tuned - we plan to explore geoengineering in more detail in the future. Further reading:  Plans to cool the Earth by blocking sunlight are gaining momentum but critical voices risk being excluded, October 2024, Albert Van Wijngaarden and Adrian Hindes Do-or-Die: Should we be talking about geoengineering?, December 2022, Land and Climate Review Soviet and Russian perspectives on geoengineering and climate management - Oldfield, J.

On 6th June 2023, the Nova Kakhovka dam was breached while under Russian occupation, releasing a wave of toxic pollution into Ukraine’s rivers. The number of casualties – both human and animal – may never be fully known. Ukraine is one of a small number of countries to include ecocide in its domestic criminal code, and the destruction of Kakhovka Dam is one of hundreds of incidents that prosecutors are studying while building environmental damages cases against Russia. On the global stage, Ukraine is leading efforts for the International Criminal Court to recognise ecocide as the fifth core international crime, alongside genocide, war crimes, crimes against humanity, and aggression.  Bertie speaks to Darya Tsymbalyuk, Assistant Professor of Slavic Languages and Literatures at the University of Chicago, about her new book, “Ecocide in Ukraine: The Environmental Cost of Russia’s War.” They discuss the destruction of the Kakhovka Dam, the sensory impact of war, and Tsymbalyuk’s intention to bring Ukrainian environmentalists and humanities scholars into this growing legal dialogue.  Buy a copy of Ecocide in Ukraine: The Environmental Cost of Russia’s War from Polity Press here.   Further reading: Destruction og Ukraine dam casued 'toxic timebomb' of heavy metals, study finds, The Guardian, March 2025 Ukraine's Ravaged Environment, The New York Times, April 2025 Constellations of Ukranian Thought and the Environmental Humanities, Tanya Richardson and Darya Tsymbalyuk, 2024 What my body taught me about being a scholar of Ukraine and from Ukraine in times of Russia’s war of aggression, Springer Nature – Darya Tsymbalyuk, July 2023  The unlikely species entangled in Ukraine's resistance to Russia, BBC, February 2024 A Landmine Detonates in the Woods, IWM – Darya Tsymbalyuk, October 2022 Darya’s fundraising for Ukraine  Click here for our website to read all our most recent Land and Climate Review features and pieces.

In 2022, the Swedish government granted an exploitation concession to Jokkmokk Iron Mines AB — a subsidiary of British company named Beowulf Mining — to develop an open-pit iron mine in Northern Sweden. The decision has been opposed by both Indigenous and environmental activists, who have expressed concerns about the mine’s impacts on Saami communities and the surrounding ecology.Bertie speaks to Tor Tuorda about the long history of extraction and exploitation in the region, the erasure of Saami culture, and resistance from Indigenous and environmental activists. Tor Tuorda is a nature photographer and Indigenous campaigner based in Jokkmokk. He is a long-time opponent of the Kallak mine, and a prominent voice in Saami activism. Audio engineering by Vasko Kostovski. Further reading: Read Tor's blog here [Swedish]'EU’s raw materials plan an attack on Indigenous land and culture, says Saami Council', The Barents Observer, April 2025'Swedish Court gives green light to controversial mining plans in Kallak', The Barents Observer, June 2024'‘The Klondike of ore mining’: Fighting for the Sami way of life', Al Jazeera, 2019Click here for our website to read all our most recent Land and Climate Review features and pieces.

Nearly half of the global agriculture market is controlled by four companies. This level of concentration - driven by decades of mergers and poor regulation - has allowed agribusiness “titans” to dominate the farming sector.  Alasdair talks to Dr Jennifer Clapp, author of a new book about corporate domination of the farm sector and why it matters. Alasdair and Jennifer discuss how and why mass-merging has led to market distortions and high prices, and what solutions could improve the state of the sector.  Dr. Jennifer Clapp is a Professor at the School of Environment, Resources and Sustainability at the University of Waterloo, Canada. She is a member of the International Panel of Experts on Sustainable Food Systems and the Scientific Advisory Committee of the UN Food Systems Coordination Hub.  Click here for our website to read all our most recent Land and Climate Review features and pieces.
