Thanks for the opinions so far.
In my mind organic doesn't imply carbon neutral, or 100% enviromentally friendly. Just that the food itself is produced using no chemicals or pesticides. Most of the organic delivery companies deliver from farms in the UK to houses. This means alot less carbon production then flying food in from the other side of the world. However I believe many of the organic delivery companies will make an effort to be carbon neutral by planting trees etc.
Organic delivery is big business in the UK. I have also seen several vans/trucks lately with .biz domains printed on them. A couple of them were food delivery related.
As for organicdelivery.info - I might build it into a directory of organic delivery companies.
