It depends on your definition of green

Yep, green jobs are trendy. And the number of them seems to be growing. But what exactly is a "green'' job?

A New York Times story comes up with several definitions.

“A green-collar job is in essence a blue-collar job that has been upgraded to address the environmental challenges of our country,” said Lucy Blake, chief executive of the Apollo Alliance, a coalition of environmental groups, labor unions and politicians seeking to transform the economy into one based on renewable energy.

Carl Pope, executive director of the Sierra Club, said: “A green job has to do something useful for people, and it has to be helpful to, or at least not damaging to, the environment.”
