An apt phrase, but new to me. I'm just taking note of it here since it seems to capture a lot of ideas in a simple phrase.
As seen in the LA Times in this opinion piece by Steve Lopez.
“I think California’s clean-coast economy is hanging on by a thread
right now,” said Ocean Foundation senior fellow Richard Charter, who has
worked for decades to protect coastal waters from offshore oil and gas
Google's Ngram viewer doesn't have enough results to graph "clean-coast economy" or its variants, suggesting that it's a newer term of art and a few directed searches for the phrase "clean-coast economy" suggest that it's a newer term.
Never underestimate the power of a well-made turn of phrase to capture the zeitgeist of the moment.
