Thousands may be driving diesel vehicles illegally after Government failures

According to a recent article by Clean Air in London (CAL)  Tens of thousands of motorists in the UK may be driving diesel vehicles illegally and risk losing their insurance or resale value – many without realising it. Clean Air in London

Government has confirmed it is illegal to use a vehicle on the road if it has been modified in such a way that it no longer meets the air quality emissions standards it had when originally produced i.e. unroadworthy.  The second hand value of such vehicles may be sharply reduced.

Clean Air in London (CAL) has been advised that removing a factory-fitted diesel particulate filter (DPF) is either a substantive or inchoate legal offence.  Despite this, the Government: is failing to stop the removal of factory-fitted DPFs; has denied a ‘cover-up’; and refuses to make an announcement warning the public.  The World Health Organisation classified diesel exhaust as carcinogenic for humans on 12 June 2012.

Association of British Insurers has told CAL that ‘Applying for or renewing insurance knowing that the vehicle is illegal or unroadworthy, would amount to misrepresentation and potential fraud’ and ‘No insurance would be offered or renewed if the owner declared to the insurer that the vehicle was illegal to drive/unroadworthy’.  CAL estimates that tens of thousands and perhaps hundreds of thousands of motorists could be affected.

CAL is calling on the Secretary of State for Transport to accept responsibility for the Government lighting this time bomb under motorists and public health and resign immediately. Continue reading

Indoor air quality guidance and compliance in healthcare premises needed

Simon Birkett, Founder and Director of Clean Air in London (CAL) has written to the Secretary of State for Health calling for an investigation into indoor air quality guidance and compliance in healthcare premises.

Indoor Air Quality Healthcare Estates

An investigation by CAL has found that Department of Health (DoH) guidance for air filtration for healthcare premises, including hospitals, has not been updated to ensure full compliance with British and European standard EN 13779:2007 for indoor air quality.

Outdoor air pollution infiltrates into buildings. Without appropriate ventilation, it accumulates and can even react with other indoor air pollutants.  Hospitals and healthcare estates, are often located in some of the busiest, most polluted urban areas therefore requiring the effective air filtration of intake as well as indoor air.

New report reveals ignorance over indoor air quality in public buildings

Air filtration in public buildings in London –   Many local authorities are in the dark when it comes to knowing if their buildings use regularly maintained air filters that comply with indoor air quality standard EN 13779, particularly schools, according to a new report from Clean Air in London (CAL).

Indoor Air Quality in Offices

In the report, the cross-party campaigning group claims that indoor air quality (IAQ) can often be worse than outdoor (or ambient) air quality, due to the many sources of pollution that exist within buildings and homes. CAL is therefore campaigning to build public understanding of indoor air quality, initially in London, with support from us here at Camfil Farr.

The report examines the issue of air filtration in public buildings in London.  It includes the results of an Environment Information Regulations request to local, regional and central Government bodies asking ‘which buildings owned, occupied or managed by the Local Authority use regularly maintained air filters that comply fully with European guideline EN 13779 e.g. offices and schools’.  The responses received are analysed and ranked.

The Greater London Authority Group (GLA Group) demonstrated detailed knowledge of its buildings.  However, CAL was surprised to discover that only eight of 15 buildings in Transport for London’s ‘Head Office Portfolio’ were due to comply fully with EN 13779 by April 2012 with seven others in 2012/2013 and many more having no expected compliance date. CAL has also been surprised to discover a big difference among the 33 local authorities in London in terms of how much they know about indoor air quality standards in their buildings. Some have been able to provide quite detailed information on compliant buildings whilst others seem to have little idea of which buildings comply with EN 13779.  Many local authorities have told CAL they do not know about compliance with EN 13779 in some or all of their schools because they are independently managed.
