Trump has already said states and municipalities are free to implement the Paris Accord as far as their jurisdiction will allow. It’s up to voters to decide (The People, remember?)

In the cases of China or India, why can't they be proactive and take steps to cut their own pollution? They don't need the US to hold their hand.
