At least in the context I was speaking to, I don't think it was a "push." Deindustrialization (esp heavy industry) had been happening for a while. Environmental issues were one of the pressures, though that precedes the climate change agenda.

It just happens to be the case that when you look back at carbon reductions, deindustrialization is one of the key contributors. Clean energy too. A lot of europe already had a lot of clean energy though.
