The clean air act was in 1967.

* Aside: EPA and the Clean Air act weren't motivated by Climate Change but by particle pollution concerns.
I don’t think that’s incorrect even if you ascribe all of the era’s environmental decision making to energy scarcity.
Carter still set a goal of 20% renewable energy by 2020, and that still would have made a significant impact.
It seems obvious to me that environmental policy was in some part driven by concern for the environment itself, but that doesn’t change the simple statement that things would have been better if we’d followed it.

* Aside, significant global warming became scientific consensus only sometime between 1979 and 1989. The global cooling thing above is wrong in that most scientists expected some warming and that it expects too much from science. It does connect to the fact there was real scientific debate at the time and not just denialism, it wasn't clear warming would be that much a problem.
This should not be a point against climate science - scientists aren't born with the correct climate model! It took time to get the modeling right, but once they did the predictions were completely accurate.
