IAQM Chair’s thoughts on the petrol and diesel ban

Wed, 07/26/2017 - 17:07

The IAQM’s Chair, Dr Claire Holman, has responded to news that the Government will be banning the sale of new diesel and petrol cars in the UK from 2040.

For many years the IAQM have highlighted the unacceptable levels of urban air pollution produced by diesel cars and the need for the UK to urgently seek to meet EU limited values. However, an outright ban on both petrol and diesel cars and vans may not be the best policy tool for achieving better air quality.

Claire says: Twenty five years ago petrol cars were the main culprit; today it is diesel vehicles causing poor air quality. Over that period engine and pollution abatement technology has changed beyond recognition and in another 20 plus years there could have been even greater advances.”

The announcement will stop research and development investment in these technologies over the coming years. The current alternatives, such as electric vehicles, can offer real benefits in urban areas in the short term but they are not necessarily the long term solution. The research and development community should not be given artificial constraints such as this ban.”

What do you think?

Setting long term stable targets allows industry to innovate towards set goals within known timetables. This policy approach has had considerable success in waste management (with the landfill tax escalator) and with carbon emissions (through the Climate Change Act), albeit neither being an outright ban. Could this announcement serve to accelerate the transition away from the internal combustion engine, to more sustainable solutions?

Or is a blanket ban on petrol and diesel too crude a policy tool? Would it be better to set enforceable, technology neutral emissions limits, backed up by a rigorous testing regime, and allow the car industry to use whatever technology they can to reach those targets?

We welcome the thoughts of IAQM members as we digest the Government’s full air quality plan to tackle NO2 emissions, published today.

IAQM reponds to Defra’s 2017 Air Quality Plans

Tue, 06/20/2017 - 16:23

The Government’s revised Air Quality Plan was released on the 5th May, after a High Court judge ruled that publication could not be delayed until after the General Election purdah period. The Government was required to prepare these revised plans, after ClientEarth won their second High Court case in November 2016 arguing that previous plans were not ambitious enough.

Alongside the new plans, a consultation was launched which closed on the 15th June: Improving air quality: national plan for tackling nitrogen dioxide in our towns and cities. The IAQM Committee has prepared a response to this consultation, in which a series of tests were applied to the proposals:

  • Does the Plan clearly set out a series of measures that will enable the UK to achieve compliance with the Directive in respect of NO2 concentrations?
  • Does it do so in a way that will achieve compliance in the shortest possible time?
  • Are the proposed measures feasible within the current structure of air quality management within the United Kingdom and the available resources?

The submission concludes that “The IAQM is not satisfied that these proposed measures will address the problem as quickly as possible”.

IAQM reaches membership milestone

Fri, 06/16/2017 - 10:56

We are very pleased to announce that in June the IAQM’s membership reached 400 members.

When the organisation was founded in 2002, we estimated that there were 400 individuals working in the whole air quality profession in the UK.  Over the past fifteen years the profession has expanded, and there is no doubt that the Institute has become the representative voice of air quality professionals in the UK.

From humble beginnings, the IAQM has grown to offer a wide range of services for members at all stages of their careers, publishing a range of guidance and position statements and running two major annual conferences: the Dispersion Model Users Group (DMUG) and Routes to Clean Air (RTCA).

Claire Holman, IAQM Chair, marked this historic milestone by saying:

“Over the past 15 years air quality has become recognised as a profession.  An increasing number of young people are opting to work in this field and enjoying the challenges; while the growing public awareness has helped our clients realise its importance.  We expect to continue to grow over the next 15 years”.

Entries for the Ian McCrae Award are now open!

Thu, 06/08/2017 - 11:25

Dr Ian McCrae was a very well respected and widely liked air quality practitioner who worked for TRL. He made significant contributions to the understanding of emissions from transport and links with air quality. Tragically he died suddenly in February 2010 aged 46.

The annual Ian McCrae award is presented to an IAQM Associate Member or Full Member who has demonstrated a commitment to the air quality profession.

This year we wish to give the Award to an Associate or Member in the early stages of their career (approximately the first five years). The winner will be given free entry to the Routes to Clean Air Conference, being held on 24th and 25th October in Birmingham, where the winner will be presented with a trophy.

How to Enter
Please submit an essay (maximum 650 words) on the following topic:

What do you think the main UK air quality issues will be in 2030?

The judges will be looking for well written and argued submissions that explain your reasoning for the future scenarios and pollutant (or pollutants) you have put forward. There is no right or wrong answer.

Entries must be submitted via email by 5pm on Monday 18 September 2017.

IAQM disappointed by delay to Government’s Air Quality Plan

Mon, 04/24/2017 - 17:19

The Institute of Air Quality Management (IAQM) is disappointed that the Government has not met the High Court’s deadline to publish the consultation draft of its 2017 Air Quality Plan.

In November, after a case was brought by the environmental law charity ClientEarth, the High Court ruled that the Government’s 2015 Air Quality Plan did not comply with the requirements of EU air quality regulations. The Court ordered the Secretary of State for the Environment, Food and Rural Affairs to publish a draft modified Air Quality Plan (and associated technical information) that complies with these requirements by 4pm today (Monday 24th April 2017).

The IAQM is disappointed that the Government has not met this deadline, and is again delaying action to tackle air pollution which is damaging public health in the UK’s towns and cities. The Government is now proposing to publish its draft plan after the General Election, on 30th June. Given the requirement, emphasised by Mr Justice Garnham when ruling on the case, for the Government to bring the UK into compliance with the law “as soon as possible”, this further delay is unacceptable.

Dr Claire Holman, Chair of the IAQM said:

The Government has known about this deadline for months and if they were serious about protecting public health they would have either published the plan before the election announcement, or delayed the announcement”.

Questions will now inevitably be raised about whether this is a genuine delay, or whether this decision was made on political grounds because the suggested measures – for example, banning diesel cars in city centres – would be electorally unpopular.

Whatever the outcome of the election on the 8th June, we hope the modified Air Quality Plan will address this public health crisis with the ambition and urgency required. The IAQM looks forward to contributing to the consultation on these plans in due course.

Time for a new Clean Air Act? environmental SCIENTIST Air Quality special

Fri, 04/21/2017 - 12:57

The IAQM are pleased to announce the publication a special edition of the environmental SCIENTIST journal, focusing on air quality.

Though experts have been aware of the issue for many years, it is only in recent years that the majority of the media and public have become aware of the severity of the air quality crisis in many of Britain’s towns and cities. But is it too little too late? The articles in this issue of the environmental SCIENTIST discuss controversial topics around air quality management and measurement and suggest ways in which both government and individuals can strive to tackle this problem.

Guest edited by Dr Claire Holman, Chair of the IAQM, and with an editorial contributed by Matthew Pennycook MP, Chair of the All Party Parliamentary Group on Air Pollution, this issue includes a range of articles from scientists and practitioners.

  1. Tackling air pollution: We need to get our Act together – Matthew Pennycook
  2. Improving air quality: Are vehicle emission limits all smoke and mirrors? – Claire Holman
  3. Electric vehicles – are we nearly there yet? – Roger Barrowcliffe
  4. Air pollution: putting people at the heart of the issues – Tim Chatterton
  5. Fact or fiction: The story of measuring NOx emissions from modern diesel vehicles – Ben Marner
  6. Enhancing Local Air Quality Management in Wales to maximise public health integration, collaboration and impact – Huw Brunt, James Longhurst, Gabriel Scally and Enda Haynes
  7. Health and education versus economic development – are our children suffering in the crossfire? – Graham Harker
  8. Air quality drives down motorway speed limit – Fiona Prismall
  9. Controlling non-road mobile machinery emissions in London – Daniel Marsh
  10. Will backup generators be the next ‘Dieselgate’ for the UK? – Kieran Laxen
  11. A new Clean Air Act – what do we want? – Sarah Legge

The publication is available to IAQM and IES members online, and hard copies will be distributed soon.

Chair’s Column, April 2017

Thu, 04/13/2017 - 11:13

If you are fairly new to air quality, and by that, I mean with less than four or five years’ experience, this column is for you.

We have started an Early Careers Group to help our Associates and less experienced Members develop their skills, and to meet others in the same position. The idea is that the group is organised and run by our members. The first event is scheduled to take place on Thursday 8th June in London, and we have plans to take it on tour to other parts of the country.

I am definitively not in the early career group, having worked in air quality management since 1976 (when I started my PhD on tropospheric ozone). But what I have learnt over the past 40 years is the value of my network. We cannot know all the answers to every problem we come across as air quality practitioners, and Google cannot always provide the answers.

I have drawn on expertise from my network on a number of occasions, and it has proved invaluable. I remember one time needing to assess the impact of a major road on air quality at a new development some 150m below the road (it was in a former quarry). I discussed the issue with Professor Bernard Fisher, my predecessor-but-one as chair of IAQM, and together we came up with a viable solution. I would have struggled without his help, having just joined an engineering practice that worked extensively on land development projects. It was my first major project of this type; having never previously undertaken land development work. These days, most of our members work on such projects, but my early career was different, working on policy at the interface between science and regulation.

Air quality managers in consultancies are generally good at teaching their staff how to undertake an air quality assessment. I suspect most are not so good at teaching their staff the wider issues that enable them to become good consultants. Our guidance requires the use of professional judgement, as it is impossible to cover all our profession’s assessment needs. Much of the time it is easy to make a professional judgement, but there will be projects where this is very difficult. It takes time to development the skills to make good judgements, especially when dealing with an issue you have not come across before.

This is why it is important that you attend as many IAQM and other events as you can, because talking to colleagues from other organisations, developing your network, listening to presentations, and asking questions, will make you a better air quality practitioner. You will broaden your knowledge, and over time develop the ability to make robust and defensible judgements.

A Member once told me that IAQM’s Routes to Clean Air Conference is not relevant to Members’ day-to-day work. I disagree. Members need to understand the wider air quality arena; modelling is just one part of our work, and is generally the easy bit. Understanding the causes of poor air quality, the limitations of new monitoring techniques, the evidence of real world emissions from vehicles, trends in air quality, and the effectiveness of measures to improve urban air quality have all been covered at our recent events. Having a broad knowledge is essential if you are going to become an air quality practitioner able to exercise your judgement in a professional manner. The importance of having a broad knowledge becomes clear when you are dealing with the public, and if you become an expert witness at planning inquiries/hearings or for litigation.

As a member of IAQM you are required to undertake Continuing Professional Development (CPD), and record it, ideally using the IES tool. The IAQM have published guidance (pdf) on what IAQM members need to evidence in their CPD submissions.

Each year the IAQM randomly audit 5% of members CPD records (in addition to the 10% IES audit). We rely on our members being truthful and realistic. If your CPD record shows that you are spending a very significant amount mentoring staff, then it is clear that this is a core part of your job and therefore does not count as CPD. Recording that you spend an hour a week reading a short internet news bulletin also seems excessive. These are two real examples from our last audit. Not only should you be accurate, but it is also good practice to update your record as soon as possible after you have attended an event, to enable you to realistically complete the ‘reflections’ section. The IES published an article on how this should be recorded last year.

The IAQM is determined to help individuals build fulfilling and successful careers in the air quality field. Sign up to the first event today to help build your network, skills and CPD record.

Reducing emissions from Medium Combustion Plants and Generators

Wed, 04/12/2017 - 11:17

In February, the IAQM committee wrote to Defra, to respond to the department’s consultation on reducing emissions from Medium Combustion Plants and Generators to improve air quality.

Amongst other points, the committee welcomed the proposal to transpose and implement the Medium Combustion Plant Directive (MCPD). The committee shares Defra’s view that, given the large number of such plant, the Directive’s effective implementation will bring about significant reductions in releases of air pollutants with associated benefits.
