ÂŁ2bn will be spent on ethical food this year
A third of Britons now believe it is worth paying more for ethically produced and organic foods in order to 'shop with a clear conscience'.

A study by Mintel also revealed that UK shoppers will spend more thanÂŁ2 billion on ethical foods this year - up almost two-thirds since 2002.

This dramatic rise is set to continue. Mintel forcast that the market for fair trade goods alone will by worthÂŁ230 million by the end of this year and almost double toÂŁ547 million by 2011.

The study found that 70 new ethical food products launched last year and 53 so far this year - up from just 25 in 2002.

The growth in 'ethical lifestyles' is demonstrated by the fact that three-quarters of adults now believe everyone has a 'duty to recycle' and that a third of people now buy fair trade products 'where available'.

Mintel senior market analyst Julie Sloan said: 'In the present climate, many companies may be hoping to improve their profile by projecting a more ethical stance. With these products becoming more widely available rapidly, the market is set to see substantial future growth.'
