Try to look beyond 10 years. Calling for more nat gas over anything else will just lead to 60% Nat gas and 0% coal in a decade. Ok, now what? Still 60% high emissions and ICE cars according to you. No, we should be yelling for solar, electric cars, wind, batteries, and nuclear. Our priority is not a half measure that helps a bit now but makes nat gas stick around even longer.
Policies like generation shifting encourage movement from coal to gas. They have been implemented in the US but were then undone by Trump and later declared unconstitutional by conservative supreme court justices.
