Reducing our reliance on cars

I know this has come up before, but it's worth raising again because cutting fossil fuel use is absolutely essential if we're ever to tackle global warming. Since the government has feebly passed the buck to local authorities on dealing with the closely linked issue of air pollution, we have to turn to our own borough, but its record is not strong. It has pressed for hybrid buses to be introduced in Putney, and that has had a definite effect (and anyway credit for that should go to TfL), though Putney High Street is still well over the legal limit for NO2, but otherwise its record is lacklustre.Now Robert Molteno of Wandsworth Living Streets has produced an interesting analysis (on which I've drawn: thank you, Robert) of the latest planned increases in parking charges in the borough - for example, increasing an annual resident's parking charge from £146 to £161, an increase running at twice the rate of inflation; the charge for a second car is only £35 more than for a resident's first car. This would have been a great opportunity to further improve air quality (by, for example, introduce higher Parking Permit charges for dirty diesels, to discourage car ownership or to raIse funds to build pedestrian and cycle-friendly infrastructure. What a missed opportunity!The paper does have a goal for reducing the number of cars owned in the borough - but the aimed reduction is only 9,218 by 2041. This is a decrease of only 11% over 27 years – or an average of 341 fewer cars (less than half a per cent of the total number) in our borough each year.So unless we can press the borough to attempt something stronger, it's down to all of us to act. One way is to walk and cycle more, thus reducing our car use. No doubt the usual suspects will complain about cycling on the pavement or people wearing lycra, but I hope this will be received more positively.One weak reason people use to argue against cycling (apart from the obvious one of the real danger from heedless - or worse - drivers, is the complaint that you can't take your shopping home on a bike. That is a particularly weak argument: for example, I've just brought home 10 kilos (22 lbs) of shopping in two panniers, and before someone says it's all right for me, I'm a youngster, I can assure you that I am very far from that.With effects of dirty air and global warming becoming ever more serious, it's past time we pressed our borough (and the government) to act, and also to act ourselves. We cannot go on as things are.

Only thing in your post, Ivonne, that I would challenge is the statement that "The first thing that people say is ban cars." Actually, I don't think anyone has said that (certainly not here on the forum), what we're arguing for - it's even on the heading - is that we need to reduce our reliance on the car. As Ruth says, the way the car is dominating our lives is horrendous; a small example: have a look at a photo of a typical town street from, say, the 1950s and compare it with one taken today (I've seen such comparisons but I can't put a finger on one just now): the way cars have taken over the road space is devastating. The car has brought great benefits - but at a terrible price in reduced health and life generally.Actually, another point about PHS: you say, rightly, that to stop cars going through PHS  would merely displace them elsewhere, so that our benefit would be gained at the expense of people where the traffic was displaced to. The answer, though, is to reduce flows through PHS *and other areas too* in a parallel exercise in traffic reduction. It's commonly argued that if you reduce traffic in some ares it will merely crop up somewhere else, but that makes the basic error of assuming the the volume of traffic is fixed. It isn't: levels are dynamic, and if it's more difficult to drive then some will be put off, depending on the level  of difficulty. That's why the traditional solution of making it flow more quickly is so wrong, because if you improve the flow it only encourages those presently deterred from joining the road and thus reproducing pollution as before, but with more cars. That's why an overall solution is needed (road pricing is one way of reducing the number of vehicles on the roads) but the big if is whether governments have the guts to confront the car lobby, and so far none have, not here anyway.

Hello Richard,I was under the (strong) impression that there was a suggestion of banning cars from PHS, or to pedestrianize PHS, on this forum a few months ago.  At the same time, there were queries as to why Putney cannot be more like Richmond and/or Barnes.  The answer I gave at the time is that Putney Hill and Putney High Street are two of three exit points of the A3 - and Richmond or Barnes do not have main roads exiting there.....Another point to be made is that for many people who live outside London, it is cheaper for them to use a car than pay annual rail season tickets.... A former boss of mine lived in Southampton and drove every day into London for years…The way cars are dominating our lives is in many ways horrendous but a lifeline to some; it is the reflection of relative increase in wealth, an increased independence for a few.  There is increased pollution for sure and reduction of health and life generally.  But this must also be seen in total context – computers, mobile phones and technological advance in general and lack of physical activity also have had, and continue to have, a very detrimental effect on health and life span.Comparing London today to the 1950s is very romantic and lovely I agree.  But the 1950s had rationing still so it was not all roses then.  The wealth of the UK did not start improving noticeably till the 80s, with Maggie Thatcher’s government.  Not only was there an increase in wealth, there was a massive change with regard to food, diversity of it, coffee started improving only then. I believe very strongly that there must be affordable alternatives to the car.  Rail fares and annual tickets are, in many cases, more expensive that driving.  Something to consider?

This confused self-regarding nonsense is more about trying to prove how amazing the world would be if everyone was like him rather than genuinely tackling the problem of emissions.The fact that he has little grasp of this complex issue is made clear in his first paragraph where he shows he doesn't understand balance that needs to be struck between combatting global warming and improving air quality. Reduction of fossil fuels is a major issue but NO2 is not a fossil fuel it is a by-product of the process by which a diesel engine functions. So a choice needs to be made - is our primary focus global warming or air quality?Diesel fuel was originally promoted in this country because it results in lower CO2 emission and lower fossil fuel use. It continues to do so. However, it does issue more NO2 leading to Mr Carter's use of the term 'dirty diesels'. In fact a Euro 5 or Euro 6 standard diesel emits virtually no particulates due to the filters that they have fitted.The problem that raises is there is no reliable research that convincingly demonstrates that NO2, even in the most elevated levels seen in urban areas, does any damage to health. Totally effective filters are not viable on larger vehicles so high NO2 levels always coincide with high particulate emissions. There is no dispute that particulates are very bad for people's health but the Government's own advisory panel has recently downgraded the health risk presented by NO2 in acknowledgement of the lack of evidence that it causes any extra harm.Therefore by switching policy emphasis away from combatting fossil fuels and CO2 by discouraging diesels all that is going to be achieved is a slight reduction in levels of an emission that may well be harmless.It is worse that that however. While various claims have been made about the reduction of life expectancy due to poor air quality have been made, the evidence is a bit sketchy. What there is overwhelming data on is how life expectancy more than anything is linked to income. Therefore if you genuinely don't want more people to die, the last thing that you should do is propose the kind of highly regressive tax that Mr Carter is so enthusiastic for. He has zero conception of what a significant negative such taxes can be for people on relatively low income and they couldn't be more carefully targeted to hit the working poor. Lots of people who need a car to take their tools to work don't make enough to get a new car every few years. I think it is a safe bet that Mr Carter never was employed in a job that required him to work with a tool.There is already a warning from France where the Gilets Jaunes movement has sprung up primarily due to a reaction to sharp rises in fuel costs. It is perfectly understandable that people will react if their already low income is being squeezed. It will be of little comfort to them that notionally the policy aims to reduce air pollution.The problem with Mr Carter's idea that all would be fine if we used a double pannier to collect our shopping is that it is a complete fantasy. Even a non-car owner generates a significant amount of vehicle movements every day by the requirement to deliver them food and services. It is easy for somebody whose lifestyle does not require the use of a car to smugly assume that all traffic on the road serves no good purpose but the reality is the proportion of vehicle journeys that are unnecessary is tiny. Therefore you are not going to solve the problem by punitive regressive taxes which won't do anything to improve air quality. Ultimately the only way to reduce road traffic is to make the alternatives better and the only way to improve air quality is through technology.

Unfortunately, "confused self-regarding nonsense" accurately described your own contribution. To take a few of your points:Striking a balance between global warming and improving air quality? Both need to be tackled: we need to reduce both CO2 emissions (to attack global warming) and harmful other by-products like NO2 - the statement that "NO2 is not a fossil fuel" is a nonsense in itself - volatile organic compounds and small particulates (to attack the issue of pollution.Euro 5 and 6 diesels may emit fewer particulates but only if the filters are maintained. And it's a mistake to imagine that the engines alone are significant producers of particulates, since tyre dust and brake linings also produce large amounts which, incidentally, is why electric vehicles are not the cure-all answer."there is no reliable research that convincingly demonstrates that NO2, even in the most elevated levels seen in urban areas, does any damage to health". Comprehensively wrong: there is a vast amount of research demonstrating the health effects: to take only two examples,try the meta-analysis in the European Respiratory Journal (https://erj.ersjournals.com/content/early/2014/02/20/09031936.00114713) and the evidence posted by the American Lung Association (https://www.lung.org/our-initiatives/healthy-air/outdoor/air-pollution/nitrogen-dioxide.html).The "idea that all would be fine if we used a double pannier to collect our shopping is that it is a complete fantasy" Of course it is, and I never suggested any such thing. There's a well-known technique of trying to destroy someone's argument by completely distorting. That's what you've done here, and it is as transparent as it is dishonest."the only way to reduce road traffic is to make the alternatives better and the only way to improve air quality is through technology"  Wrong again: a dual approach is needed to reduce traffic: by making it more difficult by taxation or restrictions (the stick) and by improving alternatives (the carrot). And improving air quality cannot wait for as yet unknown technical improvements but by more drastic measures: people's health cannot wait.

'the statement that "NO2 is not a fossil fuel" is a nonsense in itself - volatile organic compounds and small particulates (to attack the issue of pollution.'You don't understand what fossil fuels and related emissions are and why they are harmful. As they ultimately derive from animals and plants they will contain carbon. There never have been any nitrogen based life forms on this planet.'Euro 5 and 6 diesels may emit fewer particulates but only if the filters are maintained'Which they have to be because the filter is checked as part of the MOT test."Comprehensively wrong: there is a vast amount of research demonstrating the health effects"There is no such research that convincingly makes the link simply because there is no instance of NO2 existing independently of particulates so it is impossible to test. One of the links you gave lumps NO2 in with other pollutants and the other concludes it is harmful not based on original research but by looking at a number of other studies most of which had not concluded that it wasn't. 'Wrong again: a dual approach is needed to reduce traffic: by making it more difficult by taxation or restrictions (the stick) and by improving alternatives (the carrot).'The stick method that you are so fond of doesn't seem to be working. Motor vehicle journeys did fall quite sharply  up until around 2010 as taxation and other factors increased cost but since then there has been little decline despite further increases in cost brought about by policy. This would be indicating to any sensible person that demand has become inelastic to any changes in cost. This means that if you further increase taxes on motoring the extra cost will be absorbed by the motorist or passed onto the consumer.That your proposed policies wouldn't be effective is the least of the reasons for objecting. The far larger problem is that they will act as a highly regressive tax. Branding vehicles as 'dirty diesels' gives Transport for London and local authorities a great excuse for raising charges on these type of vehicle but most of them that are regularly driven around London will be for people in relatively low paid occupations. Nearly all of London's mini-cabs are run on diesel because of their greater fuel efficiency. Wealthy individuals can easily dodge these extra charges by upgrade to an exempt car which they probably would have done earlier but someone struggling to make a living may not be able to do that. Basically bad science is being used to justify revenue raising measures that will provide no benefit to the fight against climate change or to our air quality but will hit some of the less well off but hardest working sections of our society.
