River Action, the charity that campaigns about river pollution, is making a formal complaint to the Advertising Standards Authority about Red Tractor after an internal Environment Agency Report, seen by the Times newspaper, concluded that Red Tractor membership was “not a good indicator of environmental protection”. The river charity says Red Tractor ads are misleading because they claim to be a world-leading standard and their environmental standards aren't good enough. However, Red Tractor says that the analysis of the data is misleading. It insists that farms that belong to its scheme fare much better in inspections than those that don't. It says it inspects all its farmers and anyone found causing pollution would be reported and taken to task. A farmer who recorded a skylark using a microphone tied to a fishing rod and suspended from a weather balloon really did get a recording of the bird this way - it wasn't an April fool!
