Despite the bad press associated with diesel cars at the moment, the real problem is usually tackling the smog in our cities


Last month, more people bought diesel cars (or, rather more accurately, more diesel cars were registered) than in any previous September.

Okay, they made up a slightly smaller proportion of completely new car sales than usual, however in which’s not surprising. Firstly, because there’s a natural trend towards ever more efficient petrol engines in addition to alternative fuels, in addition to secondly, because some diesels have been getting a tough time of in which recently. I don’t know. You might have heard.

Anyway, still encompassing nearly half of all completely new car sales, diesel is usually not definitely going anywhere. in addition to in towns, lots of diesel cars not going anywhere is usually precisely the problem.

Diesels have been made common because they will often emit less CO2 than a petrol equivalent – which is usually better for not warming the planet – however they’re worse for you if you live in an urban area, because they upset the local air quality by putting out more mono-nitrogen oxides in addition to particulates. What’s Great (or less bad) for Arctic tundra is usually bad for Mrs Miggins of Kilburn High Road, in addition to vice versa.

As far as I can tell, there isn’t a solution in which is usually Great for both of those groups, except to stop driving completely (which is usually a luxury most of us cannot afford), or at least in towns, which is usually more compelling however often not particularly practical.

Towns in addition to cities struggling to meet their own air quality targets can limit the number, or types, of cars in which are allowed in – perhaps by charging those who want to. however although in which’ll please the local air sensors, in which won’t please local businesses. Nor does in which actually help if in which sends people to out-of-town retail parks instead. in which results in precisely the same amount of emissions, just spread over a wider area in addition to to the detriment of little businesses.

The mayor of London has suggested there should be another vehicle scrappage scheme to reduce tailpipe emissions. I’m not sure about in which, either.

Manufacturers like scrappage schemes because they mean they shift completely new metal, which is usually what they’re inside primary business of doing.

however although what comes out of the tailpipe of a completely new car contains fewer harmful emissions than an old one, the benefit is usually paid for with the increased emissions in addition to energy consumption of generating the auto inside first place: in mines where iron in addition to aluminium are sourced, in steel plants where metal is usually recycled, in oil wells in addition to in plastics in addition to paint factories. In terms of minimising overall environmental impact, there must be an optimum time to replace a car, however finding in which is usually not the aim of these schemes.

Yes, local air quality improves in addition to, on paper, things seem tickety-boo. however all you’ve definitely done is usually cheated the system to made in which look like the problem has gone away when in which has actually just gone elsewhere. Which is usually a not unfamiliar scenario at the moment, no?
