Taking this double certification into account, the world's total certified forest area as of May 2015 was about 439 million hectares, which is 10.9% of the total global forest area (4.033 billion hectares). Nevertheless, substantial growth in these regions seems far away, and it may be time for diversification and new approaches to certification. For example, a monitoring tool for REDD+ is under discussion; the drivers and incentives of certification could be enhanced if certification schemes could be used simultaneously to ensure sustainable forest management, monitor illegal logging, and deliver other accountability benefits. The IGIs are now available to be used in the development of national or subregional FSC standards (FSC, 2015b). This resulted in the immediate termination of DLH's FSC membership, while the suspension of its FSC certificates was to take effect within three months.
