Diesel Be Done For?

[system 4-50]

Why would you want to make any changes to a perfect NB engine?

You say the nicest things...

We knew about dirty diesel engines years ago. In 2000 I did a masters course in Environmental Technology/Pollution Management at Imperial. Students learned about low level air pollution - nitrogen oxides and particulate matter (pm10 and pm2.5) from diesel engines back then, and we didn't understand why the Govt of the time was encouraging the use of diesel cars. Ok, you might cut GHGs in the atmosphere over the long term, but the cost is impacts on public health in the short term, especially in our cities.

 

Seems to be in the news at the moment. This from the London Evening Standard the other day:

 

Air pollution in London is at its highest level for six years yet again today, after a warning to Londoners from Mayor Sadiq Khan.

Mr Khan took unprecedented steps on Monday to issue a “black” or “very high” warning in parts of London as pollution soared.

High readings for tiny particulate pollution were recorded before 6am on Monday at Sir John Cass’s Foundation Primary School, in the City area, Marylebone Road in Westminster, North Kensington and three sites in Camden - Swiss Cottage, Euston Road and Bloomsbury.

Yet another “black” 10/10 warning was issued on Tuesday in Swiss Cottage. It later dropped to a level nine alert.

 

And here, for example, is a primary school backing on to the towpath, and visitor moorings:

On those moorings, you often get boaters charging their batteries during the day.

More of the type of story above, and it's not too hard to imagine concerned parents putting pressure on local authorities to do something about it.
