You mean slow down by an probably insignificant amount? Like back to a few year ago levels. All while the combined rest of the world increases pollution? No one can seriously thinks this would make a change.

China's additional pollution in the last years is more than what the entire west has reduces in the same time. And we will not go back in time and stop flying and stop being mobile. The only way forward is trough superior tech which if it actually is superiors will also be cheaper and replace the old tech on its own. No artificial incentives needed. Instead we should pour that money into funding research because researching while being profitable simply takes way way longer to achieve the same.
