Green Policy Pollutes London’s Air

    The Law of Unintended Consequences strikes again. You might have noted that this problem is not unique to London — well over half the passenger vehicles sold in Europe (55% in 2012) are diesel, and every major city probably has the problem. It’s also noteworthy that, unlike the diesel pollutants, atmospheric CO2 is not a health threat.

    There is a difference between moving information by telework and moving freight. You cannot move cargo by computer, or download foodstuffs, household goods, appliances, etc. An increase in telework will have a relatively minor impact on the need to maintain a sizeable truck fleet to move consumer goods.

    The logical solution for London to have avoided the NO2 increase would have been to convert its truck fleet to run on natural gas. It generally emits at least 50% less NO2; 95% less particulate matter; as well as 20%-30% less CO2, than other fossil-based motor fuels. Unfortunately, it appears London began its diesel truck conversations prior to the rise in natural gas production because of fracking.

    There is a short-term greenhouse gas emission rise from methane, but it only last about 12 years; compare it with NO2, which lasts in the 200-year range in the atmosphere. Recent studies have indicated the amount of methane in the atmosphere has actually declined since 1990.

    What kind of ‘ideal’ world are you seeking?

    You say that ‘ideally, every driver should drive electric, emission-free cars powered by consistent renewable energy’. That would require a highly interventionist government that dictated or subsidised the use of these cars. That does not sound like an ideal kind of government.

    Ideally, every driver could drive the kind of car that best suits their needs that someone is prepared to make for them. That sounds like a better ideal kind of government.

      In an ideal world, unicorn powered environmental friendly 110% totally recycle vehicle will magically appear and transport anything and everything to and from places. At least that the gist of what the Religion of Gaia is selling. They are against anything that works, pinning their effort on the Unicorn Powered thingie.
