Because we cut our emissions by a lot while increasing energy output & manufacturing, and it's many people's #1 issue.
I don't remember hearing about climate change in the CCP's 100 year anniversary speech, just bloody head bashing rhetoric.
Other countries outsource to China as well, why haven't they been cutting their emissions, there's only 12 countries or so that have.
You can hand-wave China away ignoring the numbers, or how much we send over there, what they are creating, how they are creating it, but you aren't doing the Earth any favor.
All of that doesn't address their new coal factories or plastic dumping either. Let's get a handle on that. Then let's worry about the manufacturing emissions as we don't even have alternative solutions for concrete or steel yet. Fair?
