As global leaders jet out of Glasgow, leaving the hard bargaining to their delegates, Business Weekly looks at what the pledges made so far really mean. Will rich countries be able to support the financial demands made of developing nations to help them transition away from fossil fuels? And what did activists make of Indian Prime Minister Narendra Modi’s promise of reaching net-zero by 2070? Also on the programme, we hear why some people enjoy trophy hunting and ask whether it can ever be a useful tool for conservation. And as England's largest-ever hoard of Anglo-Saxon gold coins is found in Norfolk, we ask what happens to treasure when it’s discovered. Business Weekly is presented by Lucy Burton and produced by Matthew Davies.
