There is a risk of unintended carbon emissions through fire, insects, wind etc. Between 2006 and 2013, the area of forests certified as sustainably managed in the ECE Region expanded by 45%. Almost all ECE member States are members of one or more regional processes of criteria and indicators of sustainable forest management, notably the Montreal Process and FOREST EUROPE. Taken together these trends indicate that there are very significant areas of sustainably managed forest in the ECE Region, and that this share has been growing over the past two decades - or that there is a stronger ability and determination to demonstrate this trend.
