It can have life-changing health consequences, yet the use of the drug increased by 85 per cent between 2023 and 2024.

Folge vom 03.06.2025The Carbon Offset TrapThe market where carbon offsets are bought and sold has been projected to grow and grow, as big companies look to prove they can reach net zero. But where achieving reductions in emissions is impossible or expensive, an alternative is to try and arrange for carbon to be taken out of the atmosphere instead. The markets have thrived on linking buyers of carbon offsets - big firms, and even governments - to development projects in poorer countries, where land and labour for tree planting are cheap.But can these projects be safely verified and measured? Are local communities being exploited to try and make the maths add up? And can the industry afford to admit when a project is underperforming the expectations according to which carbon credits have been sold?Investigative reporter Max de Haldevang hears from experts and individuals directly involved in high profile carbon offset projects to find out.Producer: Robert NicholsonA Whistledown production for BBC Radio 4

Folge vom 27.05.2025Abortion on Trial: The Nicola Packer StoryNicola Packer went to Chelsea and Westminster Hospital for help after she delivered a 26-week-old foetus in her bathroom. But she was reported to the police - and arrested as she lay in bed recovering from major surgery. She was then escorted to a waiting police van and forced to spend the night in a police cell. File on 4 Investigates hears her story and reveals how, behind the scenes of the investigation, police had serious concerns over her controversial arrest. She believed she was only six weeks pregnant when she took abortion medication during lockdown - but she was prosecuted anyway. Her ordeal lasted nearly half a decade and, she says, it has had life-changing consequences for her. The case has also led to renewed calls from MP's and health professionals for a change in the law.
