Air Pollution and Asthma

The Financial Times reported this morning (23/12/2017) that the Government is going to launch a consultation on tighter restrictions on wood burning stoves. Particulates (e.g. PM2.5) as well as NOX emissions are seen as one of the reasons to reduce diesel vehicle usage but according to the FT, forty percent of particulate emissions in the UK come from burning wood and coal in homes – more than double that from diesel cars. Sadiq Khan in London is particularly concerned about the growth in the numbers of wood-burning stoves. For some reason they don’t seem to be covered by the Clean Air Acts that stopped the burning of coal in most UK cities.

Comment: it would certainly seem wise to tackle this problem. One of my local pubs recently installed such a fire in their restaurant. It may feel good to have a roaring wood fire near you over dinner, but it’s not good for air pollution or public health.

Meanwhile Private Eye published this report following the revelation that a number of top racing cyclists are taking medication: “The NHS is urging parents to look for signs of asthma in their children, which could include heavy wheezing, shortness of breath and winning the Tour de France. Another tell-tale sign your child could be asthmatic is that they’ve just signed to ride with Team Sky”.

It seems “exercised induced asthma” (EIA) is now a well-known condition so you need to add that to the list of causes of asthma that I gave in a previous blog post (see: ).

Media Coverage of Air Pollution and Electric Vehicles

With the Mayor of London’s plans for the ULEZ, his new Transport Strategy and the Government about to publish their air quality plans for cities, the issue of air pollution has been getting a lot of media coverage of late.

The Evening Standard ran an article by David Williams on the 28th June headlined “Don’t punish the car drivers for air pollution when other causes are worse”. The article said that making motorists pay punitive charges will fail to achieve major cuts in London’s pollution. This is the argument put forward by campaign group FairFuelUK who say it is more about raising cash as the revenue raised is not ringfenced to tackling emissions or congestion. One cannot but agree with them.

They also suggest that politicians are aiming for the wrong target by focussing on private cars which contribute only 11% of NOX emissions when 16% comes from gas central heating, 14% from diesel machinery and a lot from LGVs. Other sources are air traffic, air conditioning and HGVs. They also complain that local authorities have failed to cope with particulates that are left on roads by tyres and brakes.

FairFuelUK are asking people to write to Michael Gove and Theresa Coffey on the prospective additional taxation of diesel cars while promoting alternative solutions. For example, instead of an expensive diesel vehicle scrappage scheme they suggest retrofit devices can solve the problem on most vehicles. In addition, they push for the adoption of E10 fuel (an ethanol/petrol blend) which most cars can run on perfectly well and is widely available in other countries. They also promote the use of additives to reduce diesel emissions as is mandated in Texas. This can cut NOX emissions by 67%, and reduce other pollutants also. It does seem there are a number of other possible solutions that would be both cheaper and more effective than taxing motorists or forcing them to replace their vehicles – as Sadiq Khan is doing in London.

I would encourage you to support it.

In the Financial Times on the 8th July there was a good article by Neil Collins on the unforeseen consequences of the push for electric cars. It was headlined “Electric cars are a pain in the wallet for those who don’t drive them”, and it spelled out the wonders of such vehicles.

But the downside is the loss of fuel tax to the Government (£28 billion per year and rising), while electric vehicles are subsidised by the Government. In addition, there are major problems in developing the electricity supply grid to cope with future demand. He says “The energy transfer at a busy filling station is about equivalent to the output of a mid-sized power station” and goes on to explain the energy inefficiency of electric cars due to high distribution and storage costs. He notes that: “Electric cars are gathering speed thanks to politics rather than economics”.

This writer has so far avoided the lure of electric or hybrid vehicles simply because the economics did not stack up. A Prius might work well for a high mileage Uber driver and all electric vehicles have historically had problems of range, recharging time and cost. But they are getting better. I am having a test drive of Tesla Model S next week so I may be able to report my impressions in due course.

Diesel Vehicle Petition

Please would you consider signing this petition in support of clean diesel cars:

Modern diesel cars are very clean indeed and manufacturers have been encouraged to invest in clean diesel technology in the rush to minimise CO2 emissions.

The attacks on diesel cars are particularly aggressive in London while ignoring the fact that they are so much cleaner than they used to be and that most of the worst pollution from diesel vehicles in London comes from HGVs, LGVs, buses and taxis. In addition they ignore the emissions from many other sources such as home and office heating, industrial processes, etc.

This petition is already doing very well and in the few days it has been live has gained over 3,000 signatures. It is currently growing at some 1,000 a day and is gaining recognition in the media.

Please would you support this petition by signing it, supporting it, and also share it as widely as possible requesting your contacts to do likewise.
