Electric vehicle sales are soaring in Thailand and Vietnam. What’s behind the boom? And will it help the climate?

Thais and Vietnamese are switching to electric cars in huge numbers – attracted by government subsidies and a more exciting range of EVs.

Jobs in the car industry are also up in both countries as a new generation of manufacturers compete for domination of the emerging electric market.

But can the pace of growth last? Will the boom in electric cars reduce the chronic air pollution in cities like Bangkok? And will it help Thailand and Vietnam reduce their carbon emissions?

In this edition of The Climate Question, Host Jordan Dunbar chats to Ember’s Asian Energy Analyst, Lam Pham and Bloomberg’s Thailand Reporter, Patpicha Tanakasempipat.

It’s one of the most commonly debated questions in the climate world: Is this weather we’re experiencing natural, or is it linked to man-made climate change?

In this episode of The Climate Question, Hosts Graihagh Jackson and Jordan Dunbar are joined by BBC Lead Weather Presenter, Matt Taylor. Matt’s forecasts are seen not just in the UK but around the world.

Matt chats to Graihagh and Jordan about the crucial difference between weather and climate, and the challenge of communicating this on air. They discuss why heavy snowfall will still be possible in a warmer world, as well as the likely increase in droughts, heatwaves and extreme weather.

Matt also talks about whether climate change will make his forecasts more or less accurate. And he tells Graihagh and Jordan about an encounter with BBC wildlife legend, David Attenborough!

In 1986, the Chernobyl nuclear accident devastated the Soviet Union and shocked the world. But, 40 years on, are we now seeing a nuclear renaissance? And what does that mean for the climate?

Climate Question host Jordan Dunbar has just visited the most contaminated place in the world for a BBC World Service documentary. He tells co-host Graihagh Jackson about the ghostly atmosphere in the former Chernobyl control room and the huge dome that now covers the remains of the nuclear reactor that exploded.

Jordan and Graihagh also discuss how the disaster set back the nuclear power industry for decades. Now, however, nuclear is firmly back on the international agenda because of rising power demand and concerns about energy security.

With around 40 countries now aiming to build more nuclear power stations, what will this mean for the climate and the world’s goal of keeping global warming under control?

With more and more people moving to cities, informal settlements are expected to grow. When floods hit these unplanned places, it can be disastrous, as we often don’t know much about them. Crucial questions often remain difficult to answer, like how many people live there, what are the buildings made of, and could they withstand a flood?

In the township of Alexandra in Johannesburg, the BBC’s Nomsa Maseko visits a project using drones and artificial intelligence to help authorities prevent the worst impacts of flooding. And in Porto Alegre in the south of Brazil, we hear how an innovative digital map helped the emergency response – and will soon be available to all for free across the world.

Earthquakes are caused by a sudden release of stress along faults in the earth's crust, not by climate change, but some new studies suggest that melting glaciers and permafrost may influence when, where and how often seismic activity occurs.

In this episode, hosts Graihagh Jackson and Jordan Dunbar chat to seismologist Dr. Verena Simon from the Swiss Seismology Service and Associate Professor of Geosciences at Colorado State University, Sean Gallen.

How much does advertising influence what we buy and how we think?

A growing number of cities are restricting adverts for fossil fuel products, from flights and petrol cars to gas heating. From May, Amsterdam is set to become the first capital city to do so. In 2024, the UN Secretary-General António Guterres called on countries to introduce similar bans worldwide.

In this episode of The Climate Question, Jordan Dunbar asks whether banning fossil fuel adverts is a good idea and whether it makes any difference when it comes to fighting climate change.

He speaks to Marco Silva from BBC Verify about the role advertising plays in shaping public attitudes, and Anna Holligan, the BBC's correspondent in The Hague, explains how the restrictions in The Netherlands actually work.

As climate change makes the world hotter, some cities have appointed so-called Chief Heat Officers to try to improve their response to record-breaking temperatures.

In 2024, Graihagh Jackson spoke to two women who have done the job in Freetown, Sierra Leone, and Monterrey, Mexico. What does their role involve? What solutions are out there? And do they get enough funding?

Plus, Umaru Fofana reports from Freetown on what happens when extreme heat grips the city. Umaru talks to locals forced to sleep outside because of the temperature, despite risks to their health and safety. And he also investigates a new piece of building design that might help people living in informal settlements.

Transport is one of the fastest-growing sources of greenhouse gas emissions, and in cities around the world it is also one of the biggest daily frustrations. Congestion, pollution and long journeys to work affect millions of people every day.

In this episode of The Climate Question, Jordan Dunbar explores how cities can move large numbers of people more quickly, cheaply and with fewer emissions. With most urban journeys still dominated by private cars, the challenge is how to shift people towards more efficient forms of transport.

He speaks to Dario Hidalgo, a transport expert based in Bogotá, where a system known as Bus Rapid Transit has helped transform how millions of people travel. By giving buses dedicated lanes, larger vehicles and faster boarding systems, cities can move more people using fewer vehicles, cutting both congestion and emissions. Variations of the model are now being used in cities around the world.

Jordan also hears from Sarah Kaufman, Director of the NYU Rudin Center for Transportation in New York, about why similar systems can be harder to implement in dense cities, and how measures like congestion charging are helping to reduce traffic and fund improvements to public transport.

While electric cars are often seen as part of the solution, both experts say reducing the number of cars on the road altogether is key. From buses to bikes, they explore how cities might redesign transport systems to be cleaner, faster and more efficient.

War leaves a visible trail of destruction: lives and families devastated, homes and communities reduced to rubble.

But there is also a climate cost of armed conflict, and it’s an issue that Climate Question listeners have been asking about. So in this show, Host Graihagh Jackson chats to two leading experts about the carbon footprint of battle itself - the jets, the bombs, the supply lines - and the impact of maintaining armies and bases during peacetime. They discuss Gaza and Ukraine, as well as the current US-Israel war with Iran.

Graihagh also finds out if there any ways for the military to reduce their emissions and whether they see climate change as a strategic threat.
