An Asheville weekly confirms that "envirojacker" is a new word.

After noting that Asheville City Councilman and Republican Congressional candidate Carl Mumpower had used the word in a recent press release, we at Dome wondered if it was perhaps mountain slang that we'd not heard down here in Raleigh.

But a writer for the Mountain Xpress says she's never heard of it either. In addition, the alt-weekly suggests the word could be turned on its head:

Then again, the phrase "envirojacker," which combines "environment" and "jack," could have potential as a slang term among environmentalists. As in, those "envirojackers" have totally jacked the landscape with their coal mine, and they've done jack to clean up the pollution.

That's the trouble with neologisms. They don't always end up meaning what you wanted them to mean.
