Cleaning up Kensington

In November 2013 an ivy green screen was installed at St Cuthbert with St Matthias CE Primary School along a wall directly adjacent to the Warwick Road (A3220), Earls Court. Kings College London Environmental Research Group monitored the project on behalf of the Royal Borough.

Monitoring of Nitrogen Dioxide NOX and Particulate Matter PM10 sampled either side of the screen was undertaken for a period of 12 months from November 2013-November 2014. The difference in concentration between the busy roadside side and playground side of the screen was assessed as the green screen matured.


Report on the research findings of a ‘green screen’ project at St Cuthbert’s with St Matthias Primary School to reduce the impact of harmful vehicle emissions.

Results

The screen was found to be an effective pollution barrier once the ivy had started growing and a significant impact could be seen once the screen had matured. The ivy screen led to a decrease in the NO2 concentrations on the playground side of the screen by 24%, this was higher than the measurement uncertainty of 7% and was therefore significant. The decrease in the PM10 concentrations on the playground side of the screen was 38%; this was higher than the measurement uncertainty of 15% and was therefore significant.

Comparing school hours independently a reduction in NO2 concentrations of up to 36% and a reduction the PM10 concentrations of up to 41% was found. This demonstrates that the screen is very effective during daytime hours, when both emissions and exposure are highest.

The reductions in NO2 and PM10 concentrations are broadly similar; the PM10 reductions are slightly higher than those for NO2 once the green screen has fully matured. This may illustrate slightly different effects that the screen is having on gases or particles. As the NO2 concentration is lower than the PM10 the gas may be passing through the screen while the particles are being filtered by the increased foliage.

Conclusion

The project has shown us that the introduction a green screen can have a significant effect in preventing the transport of pollution from the roadside, Further work would be required to assess the impact of the screen at greater distances from the road.

Recommendation(s)

It is recommended that the Committee note the findings of the research.

It is clear that the screen has a significant effect in preventing the transport of pollution from the roadside into the playground.

The results of this research project provide an evidence base for the future use of greening initiatives within the borough to assist in the reduction of local air pollution from road side sources. This would be particularly beneficial to children and vulnerable members of the general public with medical conditions affected by poor air quality.

The Prime Minister outlines her Brexit approach

The Rt Hon Theresa May MP, Prime Minister
The Sunday Times
Sunday 13th May 2018

Trust me, I’ll take back control — but I’ll need your help

Amid all the noisy debate and technical discussions about our departure from the European Union, I want to take this opportunity to remind the British public of my mission in the negotiations. Brexit provides the opportunity to build a new relationship with the EU where we are close trading partners and strong allies but with the British government in control of our laws, our immigration policy and how taxpayers’ money is spent.

Windrush settlers

As an MP much of my time was spent in debates in Parliament or immersed in casework, but there was also the opportunity of dipping into the fantastic library in the House of Commons, I therefore had time to read several accounts of our Windrush arrivals, and those that preceded them – I particularly enjoyed the Trevor Phillips book where he interviewed and followed the lives of many individuals and their experiences.

Death toll on your conscience Mr Mayor?

On knife crime, you must and you CAN do more Mr Mayor.

As I write this, sixty young people have lost their lives this year. Sixty families grieving. This cannot go on.

As the previous Deputy Mayor of London, I saw at first-hand how you can tackle this problem. When Boris was Mayor he inherited a murder rate of over 21 young people a year (2008) from Ken Livingstone.
