Maine was the first place in the world with a point-of-harvest Master Logger Certification (MLC) program, offering independent third party certification of logging companies' harvesting practices. The certification system is built around standards that have been cross-referenced to all of the world's major green certification systems, that have been adopted by several other North American states, Canadian provinces, and a Japanese prefecture, and that have been awarded international recognition by receiving the world’s first SmartLogging certificate from the Rainforest Alliance. On October 1, 2007 the Maine MLC program and the Southern New England MLC program combined efforts to bring the Northeast Master Logger Certification Program (NEMLC) to loggers in Connecticut, Maine, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont.
