    From https://www.theguardian.com/uk-news/2022/jan/18/sadiq-khan-proposes-journey-charge-for-motorists-in-london

    "While the ambition to cut London’s emissions will also tackle home insulation and offices, Khan said he was focusing on transport, which had been slow to decarbonise – reducing emissions by just 7% between 2000 and 2018, compared with a 57% reduction from workplaces and 40% from homes."

    seems fairly astonishing - such reduction from buildings, given the continuing national lack of will and measures to really tackle the existing building stock?

    https://www.gov.uk/government/statistics/final-uk-greenhouse-gas-emissions-national-statistics-1990-to-2019

    ONS report that direct GHG emissions from residential buildings across the UK, fell by 23% from 2000 to 2018. The data doesn't tell us why, I guess from the switch to condensing boilers over that period, plus a bit from DG, CW and loft insulation.

    Dunno where their eye-catching claim of 40% reduction came from, no source was cited in the Guardian, who have reprinted it unquestioningly (as they usually do these days). Newspapers used to be reliable for checking out politicians' dodgy statistical claims - no longer - which leads to poor decision making and cynicism. Grrr.

    Possibly they are including indirect emissions, such as the much lower carbon intensity of the electricity supply to buildings since 2000, but even then I'm struggling to believe....


    The claimed 57% reduction from workplaces, can only have come from the shutdown of heavy industries and landfill and coal gas, and the transition to a services economy. No sign of that figure in the ONS data.

    ONS do agree with the claim of 7% reduction in transport emissions, mostly reductions from cars but increases from vans.

    Singapore has had electronic road pricing since last century https://en.wikipedia.org/wiki/Electronic_Road_Pricing as well as very high purchase taxes and near-mandatory scrapping of vehicles at ten years old https://dollarsandsense.sg/calculate-depreciation-scrap-value-car-singapore/ Lorries and vans used to have lights on the top that flashed whenever the drivers broke the speed limit :bigsmile: That's the way to do it :shocked:

    In France, there are interesting plans to remove diesels from the major cities. Due to the prevalence of diesels, around 75% of the existing vehicle fleet in these cities could be banned within the next few years, providing a big opportunity to shift people to alternative forms of transport.

    I reckon somebody would end up selling a lot of blue paint! :bigsmile: Singapore is also renowned for its integrated transport policy and clean public transport infrastructure. I do wonder if any of our respective governments will ever clock on to this idea as the transition will hardly work without it.

    On this note, there is also the contradiction in public health communication recently by the government effectively encouraging people into their cars instead of public transport - lets avoid the current virus and just kill ourselves slowly with the polution, shall we?

    Like last week, when London suffered from smog and people were advised not to exercise outdoors. No word about reducing car use or not firing up that woodburner....

    I think reducing energy use would be a good way forward, someone needs to set targets , insulate or live cooler to achieve the target
