Charging people from outside the area so that they are less likely to come in a personal vehicle is one of the direct goals of congestion pricing. It isn't an environmental program, it's a traffic management program and isn't greenwashing anything.
You can call it whatever you like. I didn't say it was an environmental program, it is first and foremost a revenue generation program under a clever guise to dupe towards political leaning of new yorkers.
You can read their own description, they green wash advertising cleaner air, less emissions, etc.
They didn’t need to dupe anyone; the program is indisputably not popular and they implemented it anyway. The two goals of congestion pricing have always been to generate revenue for the MTA and reduce congestion/pollution in Manhattan. They never hid that. Most transit advocates support both of those goals, and the beauty of congestion pricing (as opposed to a revenue-only option like an extra tax on businesses in the congestion zone) is that it can accomplish both at once.
I’d also note that popularity has been going up as everyone sees the benefits immediately and the predictions of a business meltdown turned out not to be true. It feels very similar to the bans on indoor smoking where smokers predicted restaurants and bars would close and the opposite happened.
