What Makes a Green Job Green?

Monica Potts says having a definition of "green jobs" doesn't bring us any closer to understanding how they fit into an economic recovery:

So, what is a green job? The two-part BLS definition, which the bureau began working on in early 2010, was released last September. It focuses on the degree of environmental impact: Green jobs must either be in industries that produce goods or provide services that benefit the environment or conserve natural resources, or must be jobs in which workers' duties involve making their establishment's production processes more environmentally friendly.
