Oysters are a Christmas staple in France, but thousands of empty shells are bound for trash bins once the festivities are over. One French company is rescuing waste shells and using them to make porcelain and paving stones. Our Down to Earth team reports.

International shipping accounts for 3 percent of greenhouse gas emissions. But a new path is emerging: starting in 2026, sailing cargo ships will set off from France to the United States, some flying the French flag. The big question is whether this innovation can succeed in convincing industry giants. Our France 2 colleagues report.

2025/12/08

Rare earth elements, which are crucial for the defence, auto and electronic industries, have become a geopolitical battleground. On Wednesday, the EU unveiled a €3 billion plan to curb its dependence on China for rare earths, since Beijing controls 95 percent of the world's supply. But a young French-American scientist has developed a groundbreaking process for recovering rare earths from neon light bulbs and potentially other electronic appliances, paving the way for the recycling of these

How can we reduce greenhouse gas emissions? In the wake of the COP30 climate conference in Brazil, attention is turning to cattle. A single cow produces between 154 to 264 pounds of methane gas per year. So could genetics lessen their impact? FRANCE 24's Charlotte Lam reports on what's being called the "cow of tomorrow".

Down to Earth ·

2025/11/24

The COP30 climate summit came to an end this weekend with a weak compromise deal that skips over most countries' key demands. The agreement pledges to provide more funding to help vulnerable nations adapt to global warming, but doesn’t explicitly mention fossil fuels – the root cause of the climate crisis. It also falls short in demanding that countries strengthen their emissions-cutting plans, which are deemed too weak. FRANCE 24's Environment Editor Valerie Dekimpe tells us more.

2025/11/14

The effects of climate change are being felt around the world, with extreme weather events becoming more frequent and intense. According to recent estimates, climate inaction is on track to cost the global economy $38 trillion per year in damages within the next 25 years. Survivors of climate disasters are also calling for the human cost of the crisis to be considered. In Belgium, our Down to Earth team met Ben, whose friend Rosa was killed in the 2021 flash floods in the Wallonia region. He hasn't

In Scotland, whisky production is facing growing criticism over its environmental impact.Many distilleries still burn peat, a soil-like material that gives whisky its signature smoky flavour. But those same peat bogs are also vital carbon sinks, storing huge amounts of CO₂ and helping fight climate change. Our Down to Earth team reports from the Scottish Highlands.

2025/10/31

In the bay of France's famed Mont-Saint-Michel, postcard-perfect villages are slowly being swallowed by the sea. In the space of just 70 years, the Saint-Jean-le-Thomas coastline has receded by 300 metres. Many residents say the question is no longer if the sea will advance, but when. So what can they do about it? Our France 2 colleagues report from Normandy.

New Delhi could see artificial rain fall over the Indian capital for the first time later this week. The regional government is trialling a cloud-seeding experiment to induce artificial rain in a bid to bring the city's severe air pollution under control. New Delhi is regularly ranked among the world's most polluted capitals. Last week, after days of fireworks to celebrate Diwali, particulate matter levels rose to more than 56 times the safe limit.

2025/10/27

Are winegrowers forever doomed to use pesticides? Some French scientists say no. A team of researchers and a burgeoning startup are working to bring microalgae-based fungicides to market. They would save vineyards from mildew and other harmful fungi, with no synthetic chemicals. Our France 2 colleagues report, with FRANCE 24's Caroline Baum.

France's organic sector in crisis: Is the end in sight?

Down to Earth ·

2025/10/20

For the past two years, the share of organic farmland has dropped drastically in France, with many farmers abandoning organic methods and reverting back to industrial farming. It means that now just over 10 percent of France's total farmland is organic, compared to a target of 21 percent in 2030 and a wider EU target of 25 percent. Organic farmers are now accusing the French government of leaving them to fend for themselves. But there could be positive signs on the horizon. FRANCE 24's Andrew

2025/10/08

Today, more and more people are rethinking their way of life: what they eat, what they buy and how they move around, all in the name of environmental concerns. Some have turned to so-called eco-villages – small communities designed to have a minimal use of resources and impact on the environment. Our Down to Earth team travelled to Scotland, home to one of the world's first eco-villages, to find out more.

Illegal trade in rare insects on the rise

2025/10/03

The illegal trade in rare insects is booming across Africa, Asia and Latin America. Exotic ants, spiders and beetles are collected and sold as pets. Some species are worth a fortune on the global black market. But scientists are raising alarm bells, as many of these insects are vital to local ecosystems. Our France 2 colleagues report.

Every year, the world throws away 1 billion tonnes of food and households are responsible for 60 percent of it. As we mark the International Day of Awareness of Food Waste, FRANCE 24 is looking at solutions to curb the problem. Ordinary citizens, businesses and even zoos have found surprising ways to save food. We take a closer look in this edition of Down to Earth.

Road to COP30: What are the climate targets?

2025/09/22

World leaders will convene at a climate summit hosted by UN Secretary-General Antonio Guterres on Wednesday in New York. Countries face mounting pressure to set more ambitious emission reduction targets for 2035 ahead of COP30 in Brazil. Governments were invited to submit their updated pledges by February 2025. Of the 195 Paris Agreement signatories, only 13 countries have met the deadline, while a total of 37 have submitted new plans. FRANCE 24’s Valérie Dekimpe explains.

From carrot flowers to potting soil made of concrete waste – could local, organic and eco-friendly bouquets be the future of floristry? In France, nine out of 10 flowers are imported, but that's starting to change. After decades of being overshadowed by the Netherlands, fierce global competition and strict regulations, the country's flower industry is bouncing back. We met with French florists, farmers and scientists who are behind a blooming revolution to revive "les fleurs françaises".

Unstoppable predator: Lionfish take hold in Greek waters

Down to Earth ·

2025/09/08

As human-induced climate change intensifies, waters are warming and the sea life within is beginning to change its behaviour. For the past couple of years, the Mediterranean Sea – one of the fastest warming areas in the world – has been attracting a litany of invasive fish prone to more tropical climates, such as toadfish, rabbitfish and the extremely invasive Lionfish. In Greece, the Lionfish has become a headache for the local fishing industry. Researchers say it can eat up to six times its weight

Is the Mediterranean turning into plastic soup?

Down to Earth ·

2025/09/01

The Mediterranean is thought to be the most polluted sea on Earth. The equivalent of 34,000 plastic bottles are dumped into it every minute. This unprecedented level of pollution is devastating for both humans and marine life, half of which are found nowhere else on the planet. FRANCE 24's Down to Earth team met with volunteers and scientists fighting plastic waste on the island of Corsica, one of the worst affected locations in the world.
