There is no universally accepted definition of “green collar” across countries. In 2021, the United Nations Environment Programme (UNEP) defined green jobs as “positions in agriculture, industry, services, and administration that contribute to preserving or restoring environmental quality.” These jobs span diverse sectors and are aimed at reducing energy use, minimizing waste and pollution, protecting ecosystems and biodiversity, and advancing economic decarbonization. A green-collar professional refers to individuals working in green jobs — the practitioners and enablers of the green transition who plays a pivotal role in shaping a net-zero future.
