Sir Mark Moody-Stuart, chairman of Shell from 1998 until he retired last year and now chairman of Business Action for Sustainable Development, says firms cannot restrict themselves to focusing on narrow short-term issues of shareholder value. 'I believe very strongly that in the end if a corporation is perceived by society - and that includes our customers and employees - as not being a useful contributor to society, that can be a real threat to its existence,' he said. He added that multinationals cannot operate successfully in a world in which they are distrusted, not least because they need to fulfil more than formal regulatory requirements. 'They need an informal social licence to operate,' he said.
