The green businesses that provide workers with green collar jobs are large, medium and small. They include for-profit and non-profit businesses, social enterprises, public sector entities, worker-owned cooperatives, and worker collectives.

They represent different sectors, such as alternative energy, materials reuse/recycling, water, sustainable food systems, green building, and sustainable transportation. What unites green collar jobs across these diverse categories is that they are all manual labor jobs that directly improve environmental quality.
