Engineers across the globe, from China to East Africa and the US, are turning to a new, nature-based solutions to fight floods, which are becoming more likely in many places because of climate change. They’re taking a pickaxe to asphalt and concrete and instead are restoring wetlands, parks and riverbanks, turning our metropolises into so-called ‘sponge cities’. Plants, trees and lakes act just like a sponge, mopping up rainwater instead of letting it pool and eventually flood our homes.

Professor Priti Parikh tells Jordan Dunbar how these spongey solutions have many benefits beyond flooding, encouraging biodiversity, helping our mental health and storing the planet warming gas, carbon dioxide. The BBC’s China Correspondent, Laura Bicker, meets the man who came up with the concept, Professor Kongjian Yu, and visits Zhengzhou, a sponge city in the making. And Katya Reyna tells Jordan how her NGO is helping low-income communities in Portland in the US to ‘depave’ disused car parks, turning them into plant-oases.

As a new play depicts the landmark global climate change agreement, the Kyoto protocol, Jordan Dunbar has a front row seat. He heads to the historic English town of Stratford-Upon-Avon to watch the opening night of the play, Kyoto, at the Royal Shakespeare Theatre. He hears why the writers, Joe Murphy and Joe Robertson decided to dramatize the seemingly slow and tedious action of a global climate change conference. And the duo explain their goal to highlight Kyoto as a ‘parable of agreement’ in a world full of disagreement.

The programme also hears from two veterans of many real world climate change negotiations, including the Kyoto Protocol, the first global agreement to set legally binding targets. Christiana Figueres was responsible for leading climate negotiations as the Executive Secretary of the United Nations Framework Convention on Climate Change and Farhana Yamin provided legal and strategy advice to the leaders of AOSIS, the Alliance of Small Island States at Kyoto and nearly every UN climate summit since. Christiana is now the host of the 'Outrage And Optimism' podcast.

If there were fewer of us, would the amount of greenhouse gasses we emit reduce? It’s a question that often creeps up in discussions about climate change. Studies show that the global population will decline eventually and populations in many rich nations are already declining. However, 11,000 scientists signed a paper warning of “untold suffering due to the climate crisis” unless society transforms, including the reversal of population growth. But an analysis by the United Nations found that affluence has a greater impact on the climate than population. When we talk about overpopulation, what are we really saying and where does the conversation go from here?

We’ve been told that big finance is crucial to the transition to net zero, and billions of dollars are invested in so-called sustainable finance every year. But the BBC’s Climate Editor Justin Rowlatt, together with the Bureau of Investigative Journalism, have been looking into a new green finance product and found that not all is quite as it seems.

Their investigation has found an example of sustainable finance backed by the multi-national bank HSBC being used to help extract a vast new reserve of fossil fuels in Brazil. And it's not the only one. Some question how this can happen, while others defend it.

Africa accounts for around 10 per cent of the world's known fossil-fuel reserves. But plans to build an oil pipeline through East Africa to transport hundreds of thousands of barrels a day have been condemned by the European Union.

The pipeline, which runs from the source in Uganda to the Tanzanian coast, will generate billions of dollars a year. But critics say it will release tens of millions of tonnes of carbon dioxide into the atmosphere.

In this programme we hear from the people involved in the fight over the East African Crude Oil Pipeline, and find out if they think it will go ahead.

We know many of the obstacles in the way of a creating a cleaner planet - making cement green, decarbonising electricity or creating affordable clean transport. But how do we get the experts the funding they need to bring these solutions to the world?

Many people see innovation prizes as the answer - from Prince William’s ‘Earthshot’ to Elon Musk’s ‘X-Prize’ there are hundreds of millions of dollars up for grabs. Is this the best way to find solutions to the climate crisis? Who really wins from these prizes, companies or the climate?

The race to reduce emissions has more and more nations reaching for the nuclear option. Nuclear power plants are being built around the world, generating carbon-free electricity day and night, windy or calm. But they also generate radioactive waste, some of which can remain deadly for thousands of years. Thousands of tonnes of nuclear waste currently sit in “temporary” sites, some decades old. This has been fuel to critics who have described nuclear power as a scourge for future generations. No country yet has a permanent solution to the problem.

Now, almost 70 years after the first nuclear plant, Finland is set to change that. Engineers have been creating a giant cavern they say will become the world’s first permanent nuclear waste disposal site. Can it silence the critics or are we just passing on the problem to future generations?

Floods in Pakistan have destroyed or damaged millions of homes, schools and businesses. So far nearly 1500 people have died and 33 million have been affected. With Pakistan contributing less than 1% to global CO2 emissions, a keen sense of injustice is felt in the country, and demands for international support have been made. The Pakistan government has called it a “climate catastrophe” and according to the World Weather Attribution group, it is likely climate change led to intense rainfall. But critics blame mismanagement and say Pakistan should have been more prepared for the inevitable. In this programme, we tell the story of the collapse of one building to see how much of the crisis can be blamed on climate change.

As climate change brings rising temperatures and shifting patterns of rainfall, animals are adapting to keep pace. Bird’s bodies are growing smaller, their wingspan longer, lizards are growing larger thumb pads to help them grip more tightly in hurricane strength winds, beak size is changing.

We visit the Galapagos, where evolution was first discovered by Charles Darwin, to investigate the many ways the behaviour and physiology of animals are changing to survive the impact of climate change. But can they do it quickly enough?

Images are a key part of communicating climate change, and shape how we understand the crisis unfolding around us. But while lots of research has been done into the language we use to talk about climate, images are often left out of the conversation.

As a result, over time, a limited set of images have come to dominate how we think of climate change – like polar bears and melting glaciers - which haven’t kept up with the changing conversation about the crisis. All too often, these images tend to be abstract, removed from our daily lives and typically don’t feature people - when we know that climate change is happening all around us, all the time, and is very much a story with people and communities at its core.

So how can we develop a new, and more effective visual language for climate change? What kind of images ‘work’ to both convey the urgency of the crisis as well as inspire behavioural change? And what are some of the ways in which photographers are seeking to represent the crisis in a way that transforms apathy into action?

Someone dies every other day protecting the environment, according to data gathered by the campaign group, Global Witness. Even higher numbers of people are attacked or threatened.

To understand why this is happening, the BBC’s East and Central Europe Correspondent, Nick Thorpe travels to the foothills of the Carpathians in Romania, to show us how important the forests there are in fighting climate change, why they’re subject to high levels of illegal logging and consequently, clashes with environmentalists. One activist, Gabriel Păun of Agent Green, describes the numerous and brutal attacks he’s experiences whilst out documenting illegal logging. We also hear from a mother, whose son was murdered when he confronted a ‘wood thief’ in 2019. Laura Furones from Global Witness tells host Graihagh Jackson why this is happening around the world and what we can do about it.

In 1985 British scientist Jonathan Shanklin and colleagues published a study that shocked the world. The study revealed a hole in the Earth’s atmosphere right over Antarctica. It had been caused over time by chemicals known as CFCs, used in things like fridges, air conditioning units and aerosol cans. These were destroying the layer of ozone in the stratosphere which protects us from most of the sun's ultraviolet radiation - without it, cases of skin cancer would soar. Less than two years after the discovery, world leaders signed an agreement called the Montreal Protocol, committing to phase out CFCs. It has been described as the most successful international treaty of all time - every UN country has signed up, and ozone is expected to return to its previous levels around the middle of the century. So what can we learn from how we tackled the ozone hole in how we address climate change?

From the Aztecs to the Zoroastrians, humans have always prayed for rain. We’ve tried dances, ritual sacrifices and even blowing up the sky to boost rainfall. This might sound crazy but desperate times call for desperate measures.

Climate change is making people desperate again, in some regions droughts are becoming more frequent and pervasive whereas in others floods threaten livelihoods and cities. We have already affected our weather cycle but can we control it? Many governments have turned to cloud seeding programmes to try to manipulate rain to fall where they desire it to. But does it actually work, and what are the potential ramifications? We speak to experts about how people are trying to create rain, whether we’re on the brink of a geopolitical nightmare.

In rural North East Spain, proposals to build hundreds of new wind turbines have sparked opposition and divided communities. And it isn’t only Spain. There has been resistance to wind power projects across the world from Mexico to the US. Opposition groups have succeeded in delaying, and sometimes cancelling, the construction of new wind farms. To move away from fossil fuels, we will need a huge expansion in renewables. But will wind power be able to meet this challenge in the face of local opposition around the world?

The Ocean, it covers more than 70% of the surface if our planet, it provides us with food, medicine and even influences the weather.

For years its also helped to mitigate the effects of climate change. Since the 1970’s over 90% of atmospheric warming caused by green house gas emissions has been absorbed by our Oceans. But this comes at a cost.

Overtime their temperatures have risen and this has had disastrous impact on some of our most important ecosystems. Join us on a dive into the world of warming waters to discover what this means for life below the waves.

Shopping online is nothing new but with the rise of influencer culture, livestreaming, and social commerce buying stuff has never been easier.

Research suggests that the production and use of household goods and services is responsible for about 60% of global greenhouse gas emissions.

So is influencer culture making us buy more - contributing to climate change? Or is it more complicated than that? In this programme we hear from Nigerian influencer Noble Igwe and eco-influencer Rosie Okotcha. As well as finding out about the growing popularity of influencers in India and the potential of Chinese live-streamers to become environmental icons.

Since the 1990s, air flight has made the world a smaller place. In one 24-hour period you can fly to the other end of the globe. In an hour you might be able to skip the traffic and fly to the other end of your country.

But this convenience comes at a cost….to the climate. Aviation accounts for somewhere between 2 to 5% of the world’s emissions. And as the world’s desire to travel proves insatiable, the number of planes in the sky each day is only increasing.

The aviation industry has aspirational plans to decarbonise using sustainable and/or synthetic aviation fuels. But these are currently some way off. In the meantime, airlines are offering carbon offsets. Offsets are controversial products and only 1% of passengers pay for them. So, this week on The Climate Question we are asking, can flying ever be climate friendly?

The development of agriculture some 12,000 years ago changed the way humans live.

As technologies have developed we’ve become more and more efficient at producing large amounts of food and feeding an ever growing population, often with the help of synthetically produced nitrogen fertiliser.

These fertilisers can damage ecosystems. They also produce a potent greenhouse gas called Nitrous Oxide which is 265 times more warming than carbon dioxide. It’s estimated that the manufacturing and use of this fertiliser contributes 2% of global greenhouse gas emissions. But is it feasible to ban synthetic nitrogen fertilisers or would that risk plunging the world into mass food insecurity?

Join presenters Qasa Alom and Graihagh Jackson as they journey from an urban garden in Sri Lanka, where a radical fertiliser ban caused chaos, to eastern Africa where Kenyan farmers are mixing tradition with new technology to try and save the world’s climate, and its soils.

Cycling is healthy, cheap - and as modes of transport go, they don’t come much greener. Worldwide, transport is responsible for nearly a quarter of all carbon emissions, with road transport alone accounting for 75% of that. But so far, most discussions on greening the transport sector have focussed on electrifying our cars, trucks and buses – overlooking the vital role that bicycles could play in the climate transition. In fact, experts say that we’re unlikely to meet our short-term climate goals without more people getting on their bikes. So what needs to change to make that happen? We look at what’s been done on streets of Bogota, New York and Kampala to get more people cycling across the world.

Along almost every tropical coastline you can find the tangled roots of mangrove trees, a natural barrier against extreme weather. They are also one of the most powerful weapons we have for fighting climate change. Mangrove forests are six times better at capturing carbon than tropical forests. But in the last 40 years up to a third of mangrove forests worldwide have disappeared.

There’s been a lot happening in our warming world and so The Climate Question is taking a break from its usual analysis to catch you up with the latest news. From worsening turbulence and plummeting planes to new rocket launches with satellites on board that hope to unlock one of the Earth’s big mysteries: clouds... and how they might impact, and be impacted, by global heating.

Plus, a look at the latest trends in clean, green energy technology. Are we investing enough in renewables to put the brakes on climate change?

Hosts Graihagh Jackson and Jordan Dunbar are joined by Tim Gould from the International Energy Agency to find out about their new World Energy Investment Report and by BBC Climate Journalist Esme Stallard to discuss worsening air turbulence and what we can do about it.

Scientists estimate that peatlands around the world hold about 350 billion tonnes of carbon. The tropical peatland of the Congo Basin – known as Cuvette Centrale - are thought to store the equivalent of 20 years of US fossil fuels emissions.

BBC Africa Correspondent Andrew Harding has been up to his neck in it, witnessing the work being done by scientists to protect it and what might threaten its future. He also hears a warning from Environment Minister, Arlette Soudan-Nonault, about the choices the Republic of Congo faces between preserving the peatlands and making use of its resources to provide a living for its population.

We find out how one simple lesson learned in Indonesia is being shared with countries in Africa and South America to help keep a global promise to protect tropical peatlands. It’s not just about promises though – financial experts explain why persuading richer countries to pay cash for “wasteland” could be good for all of us.

Reduce, reuse, recycle is a familiar mantra the world over. Recycling has been described as ‘one of the easier climate-friendly acts” that individuals can do. A recent poll found that, globally, most of us believe that recycling is the single best thing we can do to tackle the climate crisis. But there isn’t much mention of “reduce” and “reuse”.

This week, presenters Kate Lamble and Neal Razzell explore how successful the world’s recycling system really is, visiting Port Klang in Malaysia where huge swaths of the globe’s recycling gets sent only to end up... well, listen and you’ll find out! Kate and Neal will also learn how climate friendly recycling really is and whether there are other more important actions we can take to improve how we manage our waste.

We often talk about the physical costs of climate change; the economic fallout, the effect on livelihoods and damage to the earth. But all of the changes to our world caused by global warming will have an effect on our minds, our mental health too. Earlier this year the mental health challenges caused by rising temperatures and extreme weather events were spotlighted in a report by the UN’s climate science body, the IPCC. Anxiety, stress, post-traumatic stress disorder, and even suicide, are all predicted to increase as the world heats up. Jordan Dunbar looks at what this means for people living on the front line of climate change, including examples from Nigeria, India and the Philippines.

Long term climate policy has long been at odds with short-term politics. As numerous countries head to the polls this year, we visit Brazil, Australia and the United States and see how climate policy is being used as a political tool to divide voters.

During recent the elections in Australia – a country with some of the world’s highest emissions per capita – experts believe that experiencing the effects of climate change first hand brought the need for action up the agenda, leading to the unseating of the climate sceptic Liberal National Coalition. We hear from a follower of Brazilian president Jair Bolsonaro, who believes that the country’s own deforestation figures are fake. Meanwhile, in the US, we look at how the Republican party’s position changed from the 2008 presidential elections from proposing climate policies to denying that man-made climate change is real.

Recent research shows that levels of Methane gas in the atmosphere are rising rapidly. It is over 80 times more potent as a greenhouse gas than carbon dioxide so poses a major threat to the world’s goal of limiting global warming to 1.5 C. At COP26, over 100 countries signed a Global Methane Pledge to reduce man-made emissions by 2030 – experts say cutting methane emissions is ‘the most powerful lever we have for reducing warming... over the next 30 years’. So what can be done to stop the levels rising further? We hear how farmers in Bangladesh, along with other parts of Asia, are using wetting and drying techniques in rice paddies to reduce emissions; how cows are being fed special dietary supplements with a surprising ingredient: seaweed, but why naturally occurring wetlands are a cause for concern.

China currently has 53 nuclear power plants with plans to scale up significantly in the next decade, while India is planning to build 10 new power plants over the next three years. South Korea’s new government has committed to restarting its civil nuclear programme and even Japan’s prime minister has pledged to resume nuclear power in a country that has long been resistant.

Following Russia’s invasion of Ukraine, energy security has now become more of a priority with countries looking for alternatives to Russian gas. And as countries transition to renewable power in an effort to reach net zero by 2050, governments are looking for a stable, green power supply which is lower cost. In the latest IPCC report, all pathways recommended nuclear in some form to mitigate against climate change.

After nuclear disasters such as Fukushima in Japan, safety has become an even more pressing issue, both in the region and globally, in the face of a resistant public and to safeguard communities around any power plants. We gained access to the Hinkley Point power plant in the UK which has adapted the design of the reactors to make them safer after what happened in Japan; but the pace of building has been slow and costs have been high. In China, a commitment to build more has led to a coordinated approach in terms of training, the supply chain and funding. But there are challenges ahead.

Presenters Kate Lamble and Jordan Dunbar are joined by Changhua Wu, a policy analyst specialising in China's environment, energy, climate change and sustainable development; Diane Cameron, head of the Nuclear Technology Development and Economics Division at the OECD Nuclear Energy Agency; Edwin Lyman, expert on nuclear safety and proliferation; and Director of Nuclear Power Safety at the Union of Concerned scientists in Washington.

There are over 10 million electric cars on the road globally after a decade of rapid growth, representing around 1% of the world’s car stock. But there are questions about whether there is the infrastructure to match. In many countries there are not enough chargers being installed to cope with the number of electric cars being sold. There are also doubts about whether existing electricity grids have the ability to store enough capacity to cope with charging demand and whether the amount of energy required can be fulfilled by green electricity alone.

This week we look at Norway, an early adopter to electric vehicles, or EVs, and have been through a quick adaption period in which they improved their electricity grid to support night time charging, as well as improving the network of fast chargers around the country to enable EVs to take their drivers long distances.

We then look at Vancouver in Canada has been looking at ways in which they can improve their EV infrastructure, to encourage the public to make the switch away from internal combustion engines. But do they have enough public chargers to serve those without access to their own private driveway?

And finally we take a look at how Sub-Sahara Africa is electrifying motorbikes and minibuses. Many rural communities remain off-grid because demand for electricity is so low that it is not financially viable for them to build the infrastructure. For these rural areas, electric vehicles will bring a solid demand for electricity, bringing the potential for companies to make a profit from introducing solar mini-grids to those communities that don’t yet have electricity.

The renowned climate scientist and IPCC author Maisa Rojas has been making headlines after being appointed as Chile’s new Minister for the Environment. She has pledged to deliver a green, sustainable and resilient future – and a ‘just transition’ to renewables from an economy that has to date been reliant on mining, forestry and agriculture. The legacy of General Augusto Pinochet has cast a long shadow over Chile, so one of the first hurdles is a vote on a new constitution in July which would ease the passage of new climate legislation. The new government of leftist leader Gabriel Boric also faces a divided Congress, and will need to galvanise support for a radical new agenda. Chile has vast potential for solar energy and hydropower, providing the infrastructure is in place to transmit it to different parts of the country. Can the government play a leading role globally in shifting to great dependency on renewables – and closing down coal-fired power stations in the coming decade?

When talking about climate change, the term net zero has become popular with politicians over the last few years. More than 130 countries have now pledged to go net zero to help slow global warming. Reaching net zero means reducing the amount of emissions as much as possible and removing any that remain from the atmosphere. We hear from communities in South Africa, where the government plans to reach net zero by 2050. But the country is heavily tied to coal and faces several challenges around employment and energy security. And while politicians make their net zero announcements, the United Nations projects that emissions will continue to rise even with the current pledges politicians have announced. What does net zero mean and could it help climate change?

Billions of dollars have been pumped into the promise of a climate-friendly way of producing meat, but is growing a steak in a lab any better for the planet than rearing a cow on a farm? Supporters of the idea say it will dramatically reduce the impact of livestock, which is responsible for about 15% of the world’s planet-warming gases, as well as returning huge amounts of land to nature. But studies suggest cultivating meat in a lab might actually be worse for the planet, at least in the long-run – we put both claims to the test. Graihagh Jackson presents an update of a programme first broadcast in 2023.

Hundreds of youth activists travelled to Glasgow, Scotland, to have their voices heard. As we approach the halfway point between COP26 and COP27- to be held in Egypt - we want to know how young people are feeling about progress made.

We speak to Maria Reyes from Mexico, Edwin Namakanga from Uganda and Farzana Faruk Jhumu from Bangladesh, who all attended the conference. Is the world on course to protect nature, curb emissions and generate the necessary finance to help poorer nations adapt?

Helping us answer these questions is Wanjira Mathai, a COP veteran and the Vice President and Regional Director for Africa at the World Resources Institute, and COP26 president Alok Sharma. With presenters Jordan Dunbar and Mora Morrison.

As more countries launch more rockets into orbit for commercial and scientific reasons, the space industry is experiencing rapid growth.

It’s on the verge of an even greater increase as space tourism takes off. The International Space Station is now open to tourists and private companies have developed rockets that can be reused – all meaning more launches into space.

But rocket exhausts contain particles that can affect the climate. What are the potential impacts and is it time to apply the brakes to the new space race?

In the wake of Russia’s invasion of Ukraine, parts of the world are so dependent on Russian gas that they have no option but to continue to buy it. This week’s episode looks long term plans for improving energy security, particularly in Europe where the biggest focus is on increasing renewables. Whilst this sounds like great news for the climate, Europe only accounts for 10% of the worlds’ emissions. For fossil fuel rich countries like the United States, energy security policy will mean pumping more oil and gas out of the ground.

We visit Bonny Island in the Niger Delta where business in Liquified Natural Gas is booming to explore how other resource rich countries stand to gain from the increase in oil and gas prices. And ask, as the world makes plans to stop purchasing Russian oil and gas, what will this mean for Russia’s climate policy?

The Russian invasion of Ukraine has been met with harsh financial sanctions. These have come from North America and Europe. The US and Canada have also banned Russian oil and gas, but Europe has found itself unable to do so - even as natural gas prices soar. The EU receives 40% of its natural gas from Russia, and for many countries, if they turn it off, the lights will go out and they’ll be unable to keep themselves warm. As a result European money continues to pay Russia for its natural gas resources.

This episode looks at the short term plans for European countries, dependent on Russian gas, to remove it from their energy systems and ask if this could be the perfect moment to turn away from fossil fuels, including natural gas, and turn toward a much improved renewable energy network?

Scientists say extreme weather is intensifying and becoming more frequent because of climate change and the impacts are causing huge losses.

People living in Brisbane and other parts of eastern Australia dealt with those impacts recently, when heavy rain fell for days - destroying thousands of homes and at least 22 people are known to have died.

Authorities declared it a once in a-100-year-event, making it the second disaster of its kind in the same area in just 11 years. While insurers face losses trying to cover it all, reinsurers say climate change is now a number one risk.

We talk to residents in Brisbane as they clean up after the floods and ask if insurance can be the world’s safety net as the impacts of climate change intensify?

As climate change brings rising temperatures, droughts and shifting patterns of rainfall, animals are adapting to keep pace. Bird’s bodies are growing smaller, their wingspan longer, lizards are growing larger thumb pads to help them grip more tightly in hurricane strength winds, beak size is changing. We visit the Galapagos, where evolution was first discovered by Charles Darwin, and investigate the many ways animals are adapting their behaviour and physiology to survive the impact of climate change. Changes to climate are also influencing animals’ genetics, meaning that we are seeing species evolve within our own lifetime. However, most animals won’t be able to adapt quickly enough to cope with the speed they need to in order to survive in a warming world. Presenters Jordan Dunbar and Kate Lamble look at what role evolution plays in helping animals adapt to climate change.

"A brief and rapidly closing window of opportunity” is how a new major climate change report from the UN described the effect of rising emissions. Already 40% of the world's population is "highly vulnerable" to the impacts, according to the latest report from the International Panel on Climate Change. And it’s all happening much more quickly than previously thought.

Sophie Eastaugh and Jordan Dunbar discuss the findings with a panel of experts. How much more serious do things need to get before action is taken? Produced for the BBC World Service by Darin Graham.

The need to be able to store electricity as part of our low carbon future, has increased dramatically as the use of renewable energy has expanded. Both solar and wind energy rely on sunlight and weather, only providing intermittent power. Electric cars need to be able to travel greater distances on one charge and cost less to have mass market appeal. It’s clear batteries are a key - but evolving - technology. Improvements still need to be made to their safety, power and cost.

Megawatt batteries are being built in many countries, in a step toward creating a renewable energy back-up for the grid. But these batteries are made using Lithium, which is limited because of their size, the length of their lifespan, and their track record in causing fires.

We look at the limitations of the batteries that exist right now, and what new technology in the field is expected to bring in the coming 10 to 15 years. We also visit a hydro-pump powered energy storage system in Israel, where the company, Augwind, is developing an interesting alternative to electric batteries.

We hear a lot about how melting glaciers are contributing to sea-level rise but not so much about the impact inland. In places like Tajikistan, glaciers feed rivers and are a significant water source.

As they melt climatologists expect water flows to increase, contributing to a rise in mudslides and floods. But in the long term, the melting ice will lead to water shortages.

We look at mountain communities living near glaciers and try to understand what impact this is having now and what might happen in the future. What can we do to prepare for the consequences of glacier melt?

For nearly a century, governments around the world have measured the health of their economies by a single metric: GDP, or Gross Domestic Product. It measures a country’s economic growth, and over the years has become a shorthand for national progress; a rising GDP is generally understood to mean more people in work, more companies in business, living standards on the rise. Yet, as experts have argued for decades, there is a lot that GDP leaves out. While it measures the value of all goods and services produced and consumed in an economy, it doesn’t account for nature, wellbeing, or planetary health. To GDP, a 100-year-old carbon capturing tree is worthless until its chopped down and sold as timber. Cleaning up after disasters, such as extreme weather events, improve GDP due to the increase in spending - even as people and planet suffer the consequences. In an age of climate breakdown, many economists are arguing that our obsession with GDP is damaging the planet. So is it time to ditch GDP as a measure of progress and come up with a new metric that puts sustainability at its core?

Ahead of COP 26, a rush of businesses declared their commitment to “net zero” emissions targets. But concerns were raised about how credible these targets were. Critics pointed out that many companies’ plans did not require them to change behaviour any time soon, or be held accountable for realising them - and that some of their promises just weren’t good enough. In this edition of The Climate Question, Kate Lamble and Jordan Dunbar ask how much can we believe in companies’ promises on climate?

At the UN climate summit in Glasgow last year, China and the United States announced they will work together on reducing greenhouse gas emissions.

Experts say this is a significant move because China and the United States are the two largest economies and polluters.

China emits the most greenhouse gasses, around 27% of global emissions, but it is walking a narrow path between its energy crisis and its commitment to climate work.

There are reports of plans to build up to 80 new coal power plants.

Without China acting, attempts to keep global temperatures down will not work.

How committed is China to climate change?

Written into many of the promises made by countries about how they intend to achieve their UN climate pledges to reduce emissions is an assumption that technology will help them make this happen. But this technology either does not currently exist or is in its infancy.

This includes schemes to take carbon out of the air via carbon capture and storage or direct air capture and to replace our dependency on fossil fuels with green hydrogen. We visit the world’s largest direct air capture plant in Iceland and speak to the person in charge of Namibia’s grand plans to become the green hydrogen production hub of the world - can both really be scaled up in order to meet our current needs?
