Rob Dickson, director of Keep Scotland Beautiful, stressed that eco-schools are about education for sustainable development not just environmental education. He and others expressed concern that the Education Minister appeared to confuse the two in his speech.
Mr Dickson said: "It strives to get schools and their wider communities to understand, and take responsibility for, the critical balance that is necessary between social and economic as well as environmental matters. One of the key principles is inclusion, which means in this context that schools must be relevant to the whole community not just to themselves."

Lord Sewel, the Environment Minister, said in a recent strongly argued speech: "We are some way short of the critical mass of opinion for change to sustainable patterns of life." The Scottish Office would use its power, including financial incentives, to bring about changes directly and through the 95 public bodies it sponsors, Lord Sewel said.
