Costing the Earth

Green industry is heading to Scandinavia's far north. Fossil fuel-free steel and clean, green wind energy are in great demand but what does this rapid development mean for the indigenous people of the region? Richard Orange reports from Sweden. Producer: Alasdair Cross

Millions of trees were brought down by this winter's storms. Storm Arwen in November proved particularly damaging, taking out whole swathes of woodland in Scotland and the north of England. It comes at a time when there is more focus than ever on planting trees, with the urgent need to both tackle climate change and produce more home-grown timber. At the moment, the UK imports more than 80% of the timber it uses. In this programme, Tom Heap visits two forest estates in the North East of Scotland, to see for himself what havoc the high winds have wrought. One estate manager tells him that they'll be clearing up for the next three years, with an estimated 45,000 tonnes of timber now lying broken on the ground. Tom finds out what this means for the work of foresters on the estate, and how it will affect the value of the timber they'll be able to sell. Meanwhile he discovers why the National Trust for Scotland is seeing the damage caused by Storm Arwen as an opportunity to re-think the kind of woodland it has on its land. Tom talks to the Royal Forestry Society at their research site in the Chilterns, and finds out what techniques can be used to improve the resilience of woodlands to future storms. He asks whether - when the clear-up is over and it's time to re-plant - we may need to explore using different species of trees, better able to survive in the climate we expect to have in another fifty years' time. He also meets a meteorologist from Reading University, who explains what changing weather patterns may mean for storms in the future. Producer for BBC Audio in Bristol Emma Campbell

The government announced its new energy strategy last week, outlining plans to tackle energy supply over the coming decades. In this edition of Costing the Earth, Tom Heap chairs a panel discussion which looks into the detail of the strategy, and asks what it will mean for both net zero targets and household bills. He is joined by a panel of experts: Roz Bulleid, Deputy Policy Director at the independent think tank Green Alliance; Chief Political Commentator at the i-newspaper, Paul Waugh; and environmental journalist, author and campaigner Mark Lynas.

It's not easy fighting for nature in many of the former Soviet states. Antonia Bolingbroke-Kent reports from Tajikistan, on the trail of the snow leopard and the extraordinary people who protect them. This high corner of Central Asia is home to the world's biggest species of wild sheep and goats, prey of arguably the most beautiful of the big cats- the extravagantly furred snow leopard. After the fall of the Soviet Union a vicious civil war killed 100,000 people and saw many more displaced and starving. Kalashnikovs and hungry people are never good news for wildlife and, sure enough, the wildlife of the mountains was decimated. In the last few years local conservationists have taken it on themselves to declare reserves and persuade their neighbours to reduce their hunting. With minimal funding from the government and international agencies these conservationists have had to find their own ways to pay for the protection of the reserves. Most of the money to employ rangers has come from selling licences to hunt small numbers of Marco Polo sheep, Ibex and Markhor wild goats. It's a controversial approach but, in sheer numbers of endangered species, it seems to be working. Can the improvements continue as climate change brings ever harsher winters and drier summers and regional instability keeps the wildlife tourists away? Antonia meets the conservationists trying their best to protect their wildlife in the face of enormous odds. Producer: Alasdair Cross

The pandemic has changed the way we work and shop meaning a growing number of offices and retail outlets are empty. So, what do we do with them? Knock them down and start again or find a sustainable way to reuse them? The buzz word is ‘retrofit’: redesigning and refurbishing an existing building. Elsie Owusu is an architect and, in this episode of Costing the Earth, she explores this current and contentious issue. It’s usually cheaper to build new, so what can be done to encourage developers and architects to change their plans. She visits Selkirk House on Museum Street in London. Developers want to demolish this 1960s concrete tower-block and build something bigger in its place. Campaigners say that a vast amount of CO2 emissions would be saved it the building is retrofitted. Architect, Peter Fisher, takes Elsie to a 1950s, concrete, former print-works which is being refurbished. Just five years ago Peter says the decision would have been made to demolish but, times are changing, and by choosing retrofit CO2 emissions will be reduced by 50%. Smith Mordak takes a wider view of the debate, arguing that a cultural shift is needed across architecture and the associated disciplines. The automatic response to a design challenge of building new, or even building at all, should be rejected; there are more creative and greener ways of thinking to explore first.

In Northern Ireland peace and prosperity have long been prioritised over environmental protection. Tom Heap asks if a new generation can push nature and wildlife up the agenda. For decades a blind eye was often turned to suspect developments in natural areas and breaches of pollution regulations. A more recent upsurge in large-scale dairy, pig and poultry farming has added to the burden on Northern Ireland's once green and pleasant land. New laws to fight climate change and a new subsidy regime for agriculture give Northern Irish politicians and regulators the chance to put things right. With the help of BBC Northern Ireland Environment Correspondent, Louise Cullen, Tom Heap considers the issues in advance of the Stormont Assembly elections. Producer: Sarah Swadling

Energy prices have hit new heights. Gas and electricity bills will rocket for most people at the end of this month as the price cap is lifted and nobody filling their car could fail to notice record prices at the pumps. Energy too is at the heart of the biggest conflict in Europe for decades. Russia’s war machine is paid for with oil and gas and the West’s response is shaped by our reliance on that power source. What does all this mean for the environment? Can we maintain focus on carbon emissions when Russian tanks are belching their way down Ukrainian streets? Or is it an opportunity to hasten our detox from fossil fuels as we see our addiction funding war? Tom Heap discusses our energy future with James Murray of Business Green magazine, Emma Pinchbeck, Chief Executive of Energy UK and the expert on new energy finance, Michael Liebreich.

Landowners are being offered big money for land to absorb carbon dioxide emissions. What does it mean for British farming and the shape of the countryside? Tom Heap reports. Producer: Sarah Swadling

Perfluoroalkyl substances - or PFAS - are a group of thousands of man-made chemicals which have been widely used in everything from frying pans to firefighting foam. Anything which is non-stick, water-resistant or stain-repellent is likely to have been produced using PFAS. In the USA they have been linked to mass poisoning of water supplies, as the Hollywood film 'Dark Waters' documented. In this programme, Leana Hosea sets out to discover whether they are having an impact here. She teams up with environmental journalist Rachel Salvidge to investigate. They take water samples from drinking water around the country and have them analysed for the presence of PFAS. In Jersey Leana meets residents who believe their ill health is down to contamination of their drinking water, and whose blood has been shown to contain PFAS. She hears what the links are with health concerns, and finds out why firefighters are an at-risk group. Producer: Emma Campbell

On a hot summer's day the River Wharfe in Ilkley in West Yorkshire is a tempting place to swim. In 2020 it was designated as the first inland waterway to be safe for bathing. Just over a year later the water was found to be polluted by animal and human faeces and locals and tourists were advised to stay out of the river. The River Wharfe certainly isn't unique, Britain's rivers are taking the brunt of rising populations, antiquated sewage treatment and intensive agriculture. Too much waste- human, animal and chemical- is entering our rivers, exposing swimmers and wildlife to infection. Extreme weather as experienced in February is only making matters worse. Charlotte Smith and Caz Graham search for solutions to Britain's polluted rivers. Producer: Hermeet Chadha
