IEA: Larger clean energy investment needed

The International Energy Agency has called for trillions of investment in clean energy. It argues that it is the only way that the world's climate targets can be met. Tim Gould is chief energy economist at the IEA and talks us through its latest World Energy Outlook, and we get reaction from Simon Harrison, head of strategy at consultancy Mott MacDonald, which advises governments and businesses on how to move to cleaner energy sources. Also in the programme, the BBC's Frey Lindsay reports on what's being called a housing affordability crisis in Australia, where the cost of buying a home has risen sharply relative to what people earn. Plus, our regular commentator Stephanie Hare makes the case for actively using our senses to transform our experience of the world of work. This edition is presented by Mike Johnson, and produced by Nisha Patel and Sara Parry.
