If green accreditation is any measure, the United Kingdom would appear to be ahead of the U.S. Its Institution of Mechanical Engineers (IMechE) now accredits as Chartered Environmentalists if they take the required coursework and agree to a Code of Ethics.
“The designation recognises the demonstration of, and commitment to, sustainable environmental management and development. The qualification is awarded by the Society for the Environment (SocEnv) and establishes proven knowledge, experience knowledge, experience and commitment to professional standards in the environmental field,” according to IMechEs web site.
Qualification is based on a point system. CE’s must earn eight points in the classroom work and four from practical experience. They must also agree to a Code of Ethics. A quick check of web sites for the Society of Manufacturing Engineers and American Society of Mechanical Engineers does not list green accreditation although I have inquiries into both to make sure.
IMechE was founded in 1847 and has 75,000 members. The SME was founded in 1932 and boasts “influence” over more than a half million practioners. ASME claims 127,000 members and was founded in 1880.
