What are green collar jobs? Green Collar Earth has adopted the United Nations Environmental Programme definition of a green jobs as "work in agriculture, manufacturing, research and development (R&D), administrative, and service activities that contribute substantially to preserving or restoring environmental quality.  Specifically, but not exclusively, this includes jobs that help to protect ecosystems and biodiversity; reduce energy, materials, and water consumption through high efficiency strategies; de-carbonize the economy; and minimize or altogether avoid generation of all forms of waste and pollution."
