According to King’s College, the reference for air quality measurements, London is the 2,516th most polluted city in the world

We think that climate change is the key issue here, and which if properly addressed, would deal with many of today’s air quality issues. The reference work ‘Mortality Effects of Long-Term Exposure to Particulate Air Pollution in the United Kingdom’ (A report by the Committee on the Medical Effects of Air Pollutants [COMEAP], updated 2018), says clearly in its executive summary ‘As everyone dies eventually no lives are ever saved by reducing environmental exposures – deaths are delayed resulting in increased life expectancy.’  

Air quality in London started deteriorating about 400 years ago, and for the entire time the Georgians and Victorians were painting the globe pink, sulphur dioxide was around 40 times the current WHO guideline level of 20 µg/m³. It was in fact raining sulphuric acid AKA ‘acid rain’, the effects of which can be seen on the Palace of Westminster or in Turner’s paintings.  The Great Smog of 1952 that killed perhaps 12,000 appears as a peak on the graph, and created a level over 10 times the level it is now, but our nonagenarian, and in one case centenarian parents survived and are still here with us, begging the question what effect it had on long term life expectancy.

The answer from COMEAP is around six months if you could (unrealistically) remove 100% of all air pollution from all sources, or more realistically 20 days per µg/m³ removed, plus you have to live to those grand old ages otherwise healthy.  Not as much as the headlines or Twitterati would have it.

Of course this isn’t a complete list of pollutants, there’s PM2.5, PM10, NO₂, and Ozone which have differing WHO thresholds as shown here, and those with respiratory conditions are much more affected than others, explaining most of the 1952 deaths.

Cycling in Copenhagen, 2015

The CS9 saga has been running for a couple of years now, and we’re finally beginning to achieve some clarity in the plans for Hammersmith.

CS9 has been renamed CW9 “CycleWay 9” to distance it from existing Central London Superhighways, and provide a facility serving a wider demographic than those installed to date.  The image being promoted is shown in TfL’s Walking and Cycling Commissioner’s Tweet, left, although we feel obliged to point out that despite the wording, the photo is not London at all – this was Copenhagen in 2015.  Nevertheless we believe this more inclusive vision is an appropriate aspiration for our borough’s roads.

Together with other members of the community, we have been successful in persuading H&F Council that TfL’s CS9 plans were flawed, now two different cycle routes are planned:  a fast commuter route using the somewhat underused paths alongside the A4, and something closer to a “Quietway” plus urban realm improvements (greening) in King Street and Hammersmith Road. More on the council website, where an online debate has started.

We expect to be part of the planned residents consultation as we are concerned about potential negative impacts on pedestrians and retailers, significantly slower buses/traffic/increasing pollution, for which there is evidence from schemes such as Winchmore Hill and Waltham Forest.  TfL’s own CS9 Air Quality Report predicts only walking-speed traffic along Hammersmith Road at Olympia, and no overall improvement in air quality.  A council meeting is planned for 9th Sept, which you should attend if you are interested in this scheme (see our diary)…

The Special 20-page Anniversary Newsletter has been published, celebrating 30 years of Hammersmith Society Awards. Printed copies are being distributed to subscribing members.

Hammersmith Highline location (photo: Hammersmith BID)

We’re intrigued by the possibility of a linear park or alternative use for the disused part of the District Line viaduct between the Kings Mall flats and the new Sovereign Court, as proposed by Hammersmith BID and West London Link (known for the Flyunder concept) as part of the London Festival of Architecture 2019.  Inspired by the New York highline and the Promenade Plantée in Paris that preceded it, there’s a competition open for ideas – details here. The project has it’s own Twitter page, where you can follow progress.

Given the challenges of the location and some of the similarities, we’re attracted to the new tropical roof garden above the Crossrail station at Canary Wharf as a source of inspiration, but the site will lend itself to many interpretations, so do please take part if you have ideas.

Several committee members attended the latest Heathrow Consultation held on 24th Jan.  A more detailed article will appear in the next Newsletter, but in the meantime the essential take-aways are summarised in the graphic shown, short-cutting the 26 consultation documents. 

“Arrivals-1 for the northern runway”

This shows one of the most problematic proposed new arrivals flight paths “Arrivals-1 for the Northern runway” (used 75% of the time for early mornings), overlaid with a “heat map” of the Society’s membership. Make no mistake, the majority of members would be directly overflown at 2000-3000ft.  The “Arrivals-2” option is worse for some members, with overflights between 2000-2500ft in the southern part of Hammersmith.

We urge you to respond to the online questionnaire answering “neither – prefer no expansion” to most questions, or use appropriate detailed responses largely the same as Chiswick’s, see: http://chatr.org.uk. You must do this by 4th March.

Currently, no Hammersmith residents are directly overflown, and those living North of King Street (the majority of our members) hear rather less of the early morning arrivals along the river that plague those living further South, particularly in TEAM mode between 6-7am as described here.

TfL has issued its response to previous consultations on the cycle route from Kensington Olympia through Hammersmith and Chiswick, and says construction of the route on the north side of the Hammersmith Broadway gyratory will begin this year.

There are no substantial alterations to the section from Hammersmith Broadway to the end of King Street. Local criticism had centred on the congestion of traffic and pedestrians, and the  likely delays for buses if the roadway is narrowed at the east end of King Street to make space for a segregated two-way cycle lane: TfL says delivery vehicles will use parking bays or park in Blacks Road or Angel Walk. We are sceptical as to whether that message will get through to security service vans delivering to banks, for example.

There were also worries about  increased risk to pedestrians from cyclists. TfL has decided to drop the term “Super-Highway”, saying it sends the wrong message. A local family cycling group has welcomed the scheme, so let’s not forget it is not just fast commuter cyclists who want cycle lanes.  But the TfL report specifically excludes the option of a commuter route parallel to the length of the A4, and is vague about the prospect of a fast route in Hammersmith,  which the Council announced last month. 

We understand LBHF is having further discussions with TfL.
