The view from the top of business. Presented by Evan Davis, The Bottom Line cuts through confusion, statistics and spin to present a clearer view of the business world, through discussion with people running leading and emerging companies.

With so many people now living in high-consuming industrial nations, and with many commodity prices increasing, Evan asks his business guests how they plan to economise in their use of raw materials. They also discuss building design and appraise the importance of form and function.

Evan is joined in the studio by Eugene Kohn, co-founder and chairman of architecture firm Kohn Pedersen Fox Associates; Mark Price, managing director of supermarket chain Waitrose; Andy Bond, former chief executive and chairman of Asda.
