World leaders have converged in Glasgow, Scotland, to seek a new climate change deal. We get analysis of the role business can play in decarbonising the world economy, from Rowan Douglas of the resilience hub of the world's largest insurance broker, Willis, Towers, Watson, which is part of the coalition for climate resilient investment. Billionaire Dr Andrew Forrest tells us why his company Fortescue Future Industries is focused on the potential for green hydrogen in the world's future energy mix. And we further examine hydrogen's possible role as a clean fuel with Paul Elkins, professor of resources and environment policy at University College, London. Also in the programme, the chief executive of Barclays Bank has stepped down as UK regulators investigate his links with the convicted sex offender Jeffrey Epstein. Â鶹ԼÅÄ business editor Simon Jack explains the background. Plus, our regular workplace commentator Stephanie Hare explores how to make the best use of our time at work.
