From what I have read, Europe did a better than the US at the time. Maybe not on purpose.

From what I remember, they let their gas prices raise, keep public transportation viable and some countries even supported bicycling as an alternative.

But it was not enough, especially with a giant at the time spewing CO2 into the air at ever increasing rates. I remember the manufacturing smoke stacks pumping it into the air. Only in the 80s did I start seeing the smoke lessen. By the late 80s, most manufacturing left my area.
