The issue of standards is one that has attracted considerable attention. It is bound up with the process of achieving consensus on a definition of sustainable forest management. As the previous chapter showed, this is an area where there is considerable difference of opinion; where emotions are high; and where results are often vague or ambiguous. Because of this, it has been difficult to produce standards for certification that follow proven practice and methodology developed for other processes and products. The result is often a muddle between general standards, which are external to the LFMU, and detailed standards which ought to be specific and internal to the LFMU.
