In 2008 33.8% of the total consumption of sawn wood and wood based panels in the Netherlands was labeled with a certificate of sustainable forest management. 100% of the certified volume complies currently with the procurement regulations of the Dutch government. This share of total consumption is a substantial increase over 2005 when 13.3% of the total consumption was certified. This is the result of a study that Probos performed in 2009 for the Dutch government.
