Not surprise. But during Trump's tenure, he said the air is very good in US and hence not need to engage the world on that as it is in other countries but not in the US which is fresh and clean with clean air as can be seen happiness in US people and hence to be done at all. This is a self-centered way of thinking in that pollution impaired on the people is not important to the top except from pollution reports made from the top. This is disastrous considering the US polluted air is filled from military and domestic aircrafts burning their fuels across US and EU will be the hardest to address and be removed.
