Well, that was obvious from the start.
First, China is not a member of the G7, so whatever these morons decide to do to cut their own throat is fine with them. All regulation (including climate change foolishness) that happens in these meetings has no bearing on China, or Russia, or India. It only impacts a dying European economy and ties the hands of the US in competing with China, almost ensuring we will lose. The exemption for China is the fact that they did not agree to anything, and if you don't like it do something about it (like Trump did with the tariffs the left whined about repeatedly).
The western part of the world has become incredibly STUPID. I love how we are forcing our oil companies to divest productive properties (BP and RDS have been impacted the worst), and they are being sold to companies that will produce those same products far less environmentally than they would. I guess global warming is actually just regional in nature, and the stuff spewed by less capable companies/nations won't impact us so much. Idiots.
