He praised the company as the first retailer to sign up for his ambitious Terra Carta initiative.
Charles wrote: I have been so encouraged by the enthusiastic global corporate response to this call to action - there seems to be a real sense of the fierce and urgent necessity to act before it is literally too late. When I heard the John Lewis Partnership was to become the first retailer to sign up, I was particularly delighted. Not only are John Lewis and Waitrose Royal Warrant holders but, of course, Waitrose is home to Duchy Organic, the company I started more than 30 years ago to show it was possible to produce high quality food working in harmony with nature, one of the principles that lies at the heart of the Terra Carta.
