I would say that the Majesty and most other modern scooters and motorcycles meet current emissions standards but are no better or worse than cars. They do get far better gas mileage than most larger vehicles, but cars such as the Toyota Yaris, Toyota Prius and other hybrids, Volkswagens TDI diesels, Smart TwoFour and such can come very close or better in efficiency and 'green' when driven properly (I can easily squeeze 60mpg out of my Jetta diesel). The big benefits come when you compare them to SUV's and other cars that are far too big for most people's needs on a day to day basis. They also take up less space on roads and in parking lots which helps ease congestion. Less congestion equals less time sitting in grid lock which equals less polutants spewed into the atmosphere.
These machines do make a difference but it is not just a simple single answer, there are many facets as to why and how they help ease pollution.
Air injection is quite a common method of reducing emissions, but it is also quite often disabled in the search for better running machines. You can buy air injection removal kits for many bikes (I was looking at one for the Triumph Bonneville yeterday).
My honest opinion is if you are going to crusade for the use of scooters in your city do so on the reduced congestion and higher fuel mileage fronts and leave the lid on the whole emissions can of worms.
