There was no enforcement of these emission regulations before anyway. For example the biggest Natural Gas leak in US history (In California, in 2015, under the Obama administration) resulted in no penalties or criminal charges at either the federal or state level.
Trump rolling back emissions regulations is making people/corporations/countries think they need to do more about the climate.
Politicans from both political parties don't really care about climate change, but it is especially dangerous when a political claims to care about climate change, because then people are under the false impression that it is being addressed.
