My point was that misinformation makes it impossible or nearly impossible to evaluate "is this environmental or not".

Best effort is not enough to guarantee a good outcome- for example, this car is diesel and has lower emissions, therefore I will buy it and I will be reducing my own emissions turns out to not be true all the time.

Just like congestion pricing might or might not actually affect pollution in the way that it's claimed. The obvious point being that the city loves the new revenue, no matter what the level of impact it actually has.

I'm actually in favor of congestion pricing in principle (whether or not pm2.5 is reduced or not). I'm just sad that often times it's impossible to figure out what's true.
