The Climate Change Committee - the independent body which advises all of the UK governments on climate change - says that to meet targets on lowering emissions we need to eat and farm less beef. The Committee Chair Lord Deben explains why, and Tom Bradshaw from the NFU tells Caz Graham that UK beef production could actually help reduce global beef emissions. Gloucester cattle have been categorised by the Rare Breeds Survival Trust as a 'priority breed'. Farming Today has been to visit a farm to hear how the Gloucester Cattle Society is helping maintain and improve the breed. Presenter: Caz Graham Producer: Alun Beach
