Has anyone else noticed Lothian Buses smart new "ecolothian" paint jobs on the number 36 buses?
As they have branded the route "Get there Greener", I was wondering what that was all about, so I went to the Get there Greener webpage on Lothian's website.
Apparently, they are
...improving our existing fleet: as new technology comes in, Lothian Buses makes sure to take advantage of it. On Service 36, refurbished exhausts are being fitted to our buses to reduce their carbon emissions, making our bus fleet friendlier to the environment.
Interesting, thought I - why aren't more vehicles fitted with these "carbon reducing" exhaust systems. In fact, why aren't any vehicles fitted with such things, because as far as I know, they don't actually exist.
Fortunately, a bus spotter on Flickr has the answer. What the bus has is a catalytic converter in the exhaust to convert NOxes into water and nitrogen gas using ammonia - that's selective catalytic reduction treatment to you and I.
I for one am glad that Lothian is taking these steps to reduce its "carbon" emissions by treating the bus exhaust for NOx. A classic example of the PR department listening to the "boring technical jargon" that the man from the engineering department tells them and that "nobody will understand" and then turning it into something they think people will understand and just ending up with nonsense.
Look forward to what my enquiry email to their environmental department will reveal.
