Pubs are being encouraged to get involved in Organic Food Fortnight, which begins on Sept 1, by cooking up an organic breakfast.
The organiser, environmental charity the Soil Association, says consumer demand is growing for organic produce.
Pubs can capitalise on this by offering early-rising customers breakfasts sourced from organic suppliers.
The annual Organic Market Report, published to coincide with the launch of Organic Food Fortnight, will confirm a rise in demand for organic food.
Robin Maynard, the campaign's director said: "More and more people are waking up and supporting planet-friendly farming by choosing to buy organic food.
"They know it's the best way to avoid things they don't want in their or their children's food like pesticides or GM; of getting more of the good stuff, such as increased omega 3s in organic milk; as well as supporting more wildlife and cutting pollution.
"Organic farming also uses much less energy to grow our food, so producing far fewer dangerous climate change gases."
