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 to read our investigation into the UK biomass supply chain, or watch a clip from the BBC Newsnight documentary.

It is becoming common for the fossil fuel industry to sue governments that attempt to decarbonise over “lost future profits.” They do so via an obscure part of international law called international-state dispute settlements (ISDS) that can allow them to extract billions in public money. Alasdair speaks to Eunjung Lee, a senior policy advisor at think tank E3G. The two discuss how ISDS began, how the international treaties came to being predatory, and what measures countries should take to prevent the exploitation of the claims.  Eunjung Lee is a senior policy advisor at think tank E3G and is the lead investigator of international investment governance. She previously served as a South Korean diplomat and has worked in the Korean embassy in London. Further reading:  Investment treaties are undermining the global energy transition  - E3G The climate crisis requires a new approach to international investment treaties - E3G The Energy Charter Treaty remains the most dangerous investment treaty to the energy transition - E3G Clean investments shun Investor-State Dispute Settlements - E3G  Investor-state disputes threaten the global green energy transition | Science “Shocking and sad”: how corporations use investment agreements to block decarbonisation in the Global South - Land and Climate Review  How Exxon is using international law to sue the Dutch government   Click here to read our investigation into the UK biomass supply chain, or watch a clip from the BBC Newsnight documentary.

With India kicking off 2025 with an historic space-docking experiment, and Elon Musk's growing power in the US government raising questions over the future of his spacecraft and satellite companies SpaceX and Starlink, we may be at the dawn of a new era for space exploration.Unlike the 20th Century Space Race, however, it will likely be private companies that cross new mildstones - not public agencies. But who will regulate mining on the moon and tourism in space, and what are the environmental implications? Bertie talks about these issues with D. Raghunandan, Director of the Delhi Science Forum, as well as discussing the positive contributions of the space sector towards climate and environmental science. Further reading: 'Indian Space Sector on a High This Year', News Click, February 2025'Mining the moon for minerals could be worth billions, but astronomers warn it's bad news for science', Business Insider, February 2025'India File: Jostling for position in the space race', Reuters, January 2025'How Elon Musk’s partnership with Trump could shape science in the US — and beyond', Nature, December 2024'Donald Trump’s approach to US space policy could throw up some surprises, especially with Elon Musk on board', Durham University, November 2024'The dark side of SpaceX’s flight of innovation', People's Dispatch, November 2023Click here to read our investigation into the UK biomass supply chain, or watch a clip from the BBC Newsnight documentary.

Alasdair speaks to journalist Margot Gibbs about her investigation into a US government-funded PR firm that profiled pesticide scientists. Last autumn, Lighthouse Reports - in collaboration with media partners across Europe - published an investigation into v-Fluence, a US-based PR firm that worked to discredit anti-pesticide scientists and campaigners.Alasdair speaks to Margot Gibbs, a journalist who led the investigation, about its findings and what it reveals about the agro-chemicals lobby.Margot Gibbs is an investigative reporter at Lighthouse Reports focusing on money trails and food systems reporting.

Russia's invasion of Ukraine in 2022 shocked global energy markets, and changed the EU's long and short-term plans for decarbonisation. But how have three years of conflict changed Ukraine's own policies and plans around energy security and net zero? Bertie discusses this issue with Ukrainian economist Maksym Chepeliev, Research Assistant Professor at the Center for Global Trade Analysis, Purdue University, USA. Read Professor Chepeliev's research: 'Net-Zero Transition in Ukraine: Implications for Sustainable Development Goal 7',  Aligning the Energy Transition with the Sustainable Development Goals, 2024'Can Ukraine go “green” on the post-war recovery path?', Joule, 2023'What is the future of nuclear power in Ukraine?

In a recently published report, “Criminalisation and Repression of Climate and Environmental Protests”,  Dr. Oscar Berglund and his colleagues identified four key mechanisms through which climate and environmental protests are repressed: the introduction of new anti-protest laws, the broadening use of existing legislation, excessive policing and killings and disappearances of activists. Alasdair and Oscar discuss the findings of the report and the ways in which the clampdown on climate protest represents a threat to both democracy and net zero targets. Oscar Berglund is Senior Lecturer in International Public and Social Policy in the School for Policy Studies at the University of Bristol. He is an expert on climate change activism and civil disobedience.Audio engineering by Vasko Kostovski.Further reading:Criminalisation and Repression of Climate and Environmental Protests, University of Bristol, 2024Civic Activism in an Intensifying Climate Crisis, Carnegie Endowment for International Peace, 2024 Saving Ourselves: From Climate Shocks to Climate Action, Columbia University Press, 2024Click here to read our investigation into the UK biomass supply chain, or watch a clip from the BBC Newsnight documentary.

“The capitalist system is necessarily built on creating ecological crises.” Bertie speaks to Ståle Holgersen about his new book Against the Crisis: Economy and Ecology in a Burning World, in which he argues that, contrary to popular economic thought, economic crises are not triggered by ecological ones but instead the capitalist economy benefits from ecological crises. Bertie and Ståle discuss the ways in which crises are defined, the drawbacks to arguments for degrowth and the potential solutions to the climate emergency. Ståle Holgersen is a Senior Lecturer in Human Geography at Stockholm University and a member of the Zetkin Collective, an ecosocialist group of scholars and activists primarily working on the political ecologies of the far right.Against the Crisis was published last month and is available to buy from Verso here.Further reading:Read an extract from Against the Crisis on Land and Climate Review. White Skin, Black Fuel: On the Danger of Fossil Fascism, The Zetkin Collective, 2021Searching for “Solutions” to Crisis: A Critique of Urban Austerity and Keynesianism, Uppsala University, 2018Destroy what destroys the planet: Steering creative destruction in the dual crisis, Uppsala University, 2016Click here to read our investigation into the UK biomass supply chain, or watch a clip from the BBC Newsnight documentary.

One month ago, Prabowo Subianto was inaugurated as the new president of Indonesia. An investigation by The Gecko Project has revealed that Subianto has invested in or owned companies involved with rainforest logging, coal mining, palm oil production, and industrial fishing - but many of the companies appear to be inactive. Do these investments representing potentially concerning conflicts of interest, or are they par for the course? Are his own claims of enormous wealth accurate or exaggerated? Alasdair speaks to the author of the Gecko Project research, Margareth Aritonang, who is also the Pulitzer Center's 2024 Rainforest Investigations Fellow for Indonesia.
