M&S outlines the benefits of going green

Marks & Spencer's Richard Gillies, the director of Plan A and sustainable business, and Hunter Lovins a sustainable business expert, outlined the case for green business at SA Partners' Lean & Green conference on Thursday.

Lovins said: "Companies that go green and lean are the billionaires of tomorrow. Only companies that make sustainability a goal will succeed." Marks & Spencer will sell its first carbon neutral bra later this year.
