I’ve read elsewhere that green jobs are from one to three percent of CA jobs, depending on how one defines “green” jobs. I know that some definitions are pretty silly, including for example all trash haulers, recyclers, etc.
What we do know is that if you double the number of green jobs, and in the process cripple the vast majority of jobs in the rest of the economy, you have a net job loss in the state.
And BGIG, in the early part of the lengthy study you cited here, that is exactly what it predicted.
