Making fuel out of food. Sounds like it could be pretty sustainable, right? But then again, does it make sense to be growing crops for fuel that could otherwise be food? We travel to the US, Kenya and Germany to interrogate how biofuels came about, their promises and drawbacks and why it is we're still using them. This episode originally aired in December 2023.

Protecting African wildlife is a big deal - and big business. It's often linked to tourism, which is not always a reliable income stream and can have major impacts on animal habitats. We head to Kenya to meet the black rhino, hear about South Africa's post-pandemic struggle, and chat to carnivore ecologist Mordecai Ogada about conservation colonialism. This episode originally aired in July 2022.

Peat bogs are enormous carbon sinks. They store twice the amount of carbon dioxide compared to the planet's forests. But ever since people discovered peat was useful for gardening, farming and heating, they've been digging it up, selling it, and releasing gigantic amounts of CO2 in the process. Now, Germany wants to keep its peat in the ground and is on the hunt for more sustainable alternatives.

They're beautiful. They're historic. But they're not really built for this new era of extremes. From Paris to Venice to Rotterdam, how European cities are trying to adapt — and what's standing in their way.

Putin's assault on Ukraine triggered an energy crisis that sent Europe's economies into a tailspin and put the European clean energy transition to the test. But how did the European Union, a leader in climate action, become so dependent on Russian oil and gas to begin with?

It's perfectly natural and something we do every day. Whether you use a squat toilet, a pit latrine or a water closet, humans need to go. But the ways we do so are often not very efficient, useful or good for the environment. So we're taking a look at the history of human excrement and some creative solutions to dispose of and repurpose our waste.

Microplastics have been found everywhere — from the deepest parts of the ocean to the heights of Mount Everest. A problem that is set to intensify as we produce over 400 million tons of new plastics every year. But just how dangerous are microplastics? And what can we do about them? We share an episode from our On the Green Fence colleagues, who delve into the plastic problem in their new season.

We hear from people in California whose home insurers have left them in the lurch as weather extremes intensify in the state, and talk to an expert on disaster risk and adaptation about what we need to help protect our homes against the inevitable. And from high up in the Austrian alps, we get a reality check from climate scientists about the future of our alpine glaciers.

Writer and stylist Aja Barber on the imperialism of the fashion industry and how to kick your shopping addiction. And how Kenya's dealing with your unwanted clothing.

What do you do if there isn't enough fresh drinking water around? According to the World Resources Institute, a quarter of the world's population doesn't have enough water to meet demand. DW explores ways to combat water scarcity.

We hear from Russian climate activists and environmental organizations working in exile. And we take you to Svalbard in the Arctic to learn about life on this remote archipelago and hear from the climate scientists studying its unique ecosystem.

Each year, the world produces 430 million tons of plastics – and that figure is set to triple by 2060. How did plastics become such a big part of our lives? And what can we do reduce the harm they cause? Today, we share an episode from our colleagues at On the Green Fence, who delve into the plastic problem in their new season.

As the northern hemisphere's summer heat intensifies, wildfires burn from Greece to Algeria to California, and climate scientists admit that even some of these extremes were beyond their predictions, we talk drought, heat, fire — and what happens when that collides with mass tourism.

We visit the state of West Virginia in the United States to hear from people grappling with the phase out of coal mining. What's next for this poor state where the coal industry has dominated for more than 100 years? Julia Kastein investigates.

Solar energy is about to get a push in Croatia which has a lot of sunshine, but so far hasn't really done much with that potential. Food waste is a global problem. In many countries of the global south, it's often down to being unable to keep produce cool. Could solar power help? And we check in with a low-lying coastal community in the US that's already feeling the effects of sea level rise.

Why the survival of the Mexican axolotl matters for keeping Mexico City's temperature down. The special carbon-capturing capacities of clams. And a new, all-natural woolly lawnmower taking off in France.

We hear about how used cars from wealthy countries are getting a new lease on life in Ghana. And we talk to a transport sustainability researcher about why that kind of upcycling isn't as good for the environment as it might seem, as well as what reform could look like. And we visit Norway, where we meet those for and against the idea to mine its deep sea for critical minerals.

As fires are burning in Canada in what's been called an unprecedented wildfire season, with smoke drifting over to the United States and even across the Atlantic Ocean over to European countries, we talk fires and drought on the show. How should we deal with wildfires? What can we do to prevent the worst? And do controlled fires have a place when it comes to prevention?

How do sperm whales express their cultural differences? And what kind of music would birds and the wind make if you gave them the chance? In today's episode, we listen to some curious soundscapes, as well as hear from the climate scientists in Maryland trying to figure out what the future will look like if we change one of Earth's hardest working carbon sinks: saltwater marshes.

We talk to author & environmentalist Bill McKibben about the link between power, Russia's war and the climate crisis, and what people often overlook in the fight against it. We also travel to a place bearing the consequences of Germany's exit from Russian coal. And, from Lithuania, we ask: how is climate change altering the way we understand seasons?

We talk to renowned Indian author Amitav Ghosh about the origins of the climate crisis, the story of one very important spice, and why he prefers the term "planetary crisis" to the climate crisis.

This week we're sharing an episode of Drilled, a true-crime climate podcast we love that describes itself as Law & Order meets the climate crisis. This is episode one from their new season that follows the story of a Guyanese reporter as she tries to find out what kind of deal was struck between ExxonMobil and the Guyanese government after they discovered oil reserves off the country's coast.

We hear from people in Puchuncaví, Chile, who want to reclaim their region from industrial exploitation. And we talk to author and expert Saleem Ali about how to reduce the harm of mining and refining the minerals critical to harnessing renewable energy and powering electric vehicles.
