The Bureau of Labor Statistics (BLS) is collecting and producing information on the occupational employment and wages of green jobs. BLS is using two approaches to measuring green jobs: the output approach, which identifies establishments that produce green goods and services, and the process approach, which identifies establishments that use environmentally friendly production technologies and practices. As part of the process approach, BLS has a special topic survey underway called the Green Technologies and Practices (GTP) survey. The GTP survey will measure jobs in which workers' duties involve making their establishment's production processes more environmentally friendly or use fewer natural resources. The GTP survey will first identify whether the establishment uses green technologies and practices and, if so, what workers they have, if any, whose duties are related to these practices. Occupation and wage data will be collected for workers that spend more than half of their time working with green technologies or practices.
