Sustainably managed forests are those whose management implements performance standards based on internationally agreed environmental, social and economic requirements that form the cornerstones of sustainability. Although many forests are sustainably managed, the only way to provide credible proof of this is through independent checking.

Therefore someone who is independent, qualified and impartial - a certifier - needs to check that the forests are managed on the ground according to these cornerstones and other key elements such as international conventions including the International Labour Organisation (ILO) core conventions. This is called forest certification.
