Summary of petition

‘We the undersigned are concerned at the high levels of harmful exhaust emissions, including Nitrogen Dioxide, from diesel engine buses on Chamberlayne Road. We call on the Mayor of London (Chair, TfL), Leon Daniels (MD, TfL), Cllr Muhammed Butt (Brent Council) to introduce low emission hybrid buses on all 7 bus routes through Chamberlayne Road by March 2016.’

“Thank you for your letter of 3 December enclosing a petition about low emission bus routes travelling through Chamberlayne Road. Considerable work has already been undertaken to reduce oxides of nitrogen (NOx) across London including this important corridor. NOx is made up of nitric oxide (NO) and nitrogen dioxide (NO2) but ultimately oxides to NO2 in the atmosphere. In terms of the six principal routes (6, 28, 187, 302 and 452) that use Chamberlayne Road, Transport for London (TfL) forecasts tailpipe emissions from these vehicles has fallen 44 per cent compared to 2012 and will be 55 per cent lower by 2018. This process will continue as part of the fleet replacement plans and preparations for the Ultra-Low Emission Zone (ULEZ) in 2020. Improving performance has been achieved through retrofitting Euro III buses with selective catalytic reduction equipment which reduces tailpipe NOx by up to 88 per cent, and introducing newer vehicles including the ultra-low emission Euro VI engine which can reduce NOx up to 95 per cent compared to a standard Euro III vehicle. TfL’s forecasts are based on the number, type and mileage of buses allocated to the routes during peak times. Emission figures are based on the independent Millbrook test cycle which shows what NOx buses would emit per mile and provides accurate benchmark comparisons. The decline in emissions outlined above highlights the scale of progress made to date. As ever, we can always do more and I am committed more than ever to ensuring we drive emissions down further. This phased approach is also a much more cost efficient solution than breaking contracts mid-term and ensures investment is targeted at achieving the greatest overall impact for all parts of London.”
