One of the LEN proposals included options for restricting access to Beech Street, which runs underneath the Barbican, to all but the cleanest vehicles. The CERC Consultancy team worked with WSP to quantify the air quality impact of a ...

  • EPA proposes stronger air quality standards for nitrogen dioxide

    For the first time in more than 35 years, EPA has proposed to strengthen the nation’s nitrogen dioxide (NO2) air quality standard that protects public health. The proposed changes reflect the latest science on the health effects of exposure to NO2, which is formed by emissions from cars, trucks, buses, power plants, and industrial facilities and can lead to respiratory disease. “We’re updating ...

  • London road traffic NOx emissions still below 50% of pre-COVID-19 levels

    CERC continues to run its inverse modelling system (details in our April News item) to determine NOx emissions in London as easing of the lockdown progresses. The latest model calculations up to July 17 show that whilst there has recently been some increase in emissions, they typically remain below 50% of the pre-COVID values. Consistent with this, London road traffic NOx emissions for our ...

  • Air quality modelling to support Runnymede`s Local Plan

    Runnymede Borough Council is preparing a Local Plan to guide development in Runnymede in Surrey, south west of London. The CERC Consultancy team carried out air dispersion modelling using ADMS-Urban to identify the baseline air quality profile across the area and to assess air quality for future scenarios (2030 and 2036), with and without developments associated with the Local Plan in place. The ...

  • High NOx Emissions from Diesel Cars

    It is time to sell your diesel car. In a few years you will not be able to use it in a city. The real drive emissions measurements from passenger cars are giving astonishing results. A new diesel car has 10 times higher NOx emissions compared to a petrol car. Even worse, the NOx emitted from the diesel car is up to 50% emitted as NO2. The NOx emitted from a petrol car is only a few % emitted as ...

  • Environnement S.A announces the AS32M: the unique analyser allowing quick and direct measurement of NO2

    The European Directive 2008/50/EC requires the measurement of nitrogen dioxide (NO2) at minima in all agglomerations of more than 100 000 inhabitants. Currently, some of these sites do not meet the limit values and quality objectives set, particularly on sites located in the vicinity of roads (traffic sites), directly impacted by vehicle emissions. The uncertainties related to measurement ...

  • Children with asthma affected by `safe` levels of air pollution

    Children with asthma living in cities are especially vulnerable to urban pollution. Emissions from motor vehicles, in particular, are thought to provoke asthma-related symptoms. New research suggests that even 'safe' levels of atmospheric pollutants can affect children with asthma, causing breathing difficulties and an associated increase in health problems. Researchers examined the relationship ...

  • ET helps test the air at a Bristol city centre school

    ET’s Sales & Marketing Director, Duncan Mounsor, joined Shadow Environment Minister Barry Gardiner MP and Thangam Debbonaire (Labour Parliamentary Candidate for Bristol West) raising public awareness of air pollution and testing the air quality outside a Bristol city centre school. Duncan explains “ideally I’d have liked to have used one of ET’s professional ...

  • Irish EPA assesses NO2 in Dublin using ADMS-Urban

    The Irish Environmental Protection Agency has published new evidence on NO2 levels in Dublin. The report has been widely covered including by The Irish Times and RTE. The EPA report draws on a modelling study carried out by CERC using ADMS-Urban. CERC used traffic data provided by Dublin City Council, and emissions data from the EPA and the MapElre project. LIDAR height data was analysed to ...

  • London air quality: modelling Brent`s proposed new Energy Centre

    The CERC consultancy team investigated the air quality impact of a proposed Energy Centre, comprising boiler and CHP plant, in the London Borough of Brent. Brent Council is procuring a district energy network as part of their South Kilburn regeneration project. The associated Energy Centre will include four boilers and up to two CHP units. Two new apartment buildings will be built close to the ...

  • LondonAir Nowcast launched

    The LondonAir Nowcast has been launched as part of an updated LondonAir website. The LondonAir Nowcast uses a combination of measured and modelled NO2 and PM10 concentrations to produce a 20m resolution map of air pollution in the capital each hour. The LondonAir Nowcast is an important step forward to help Londoners visualise the air pollution that affects their daily lives. The Nowcast maps are ...

  • Volkswagen - EMIT Can Account for Real-World Diesel Emissions

    Analysis of measurements from the last decade throughout Europe have demonstrated that ambient NOx and NO2 concentrations are not decreasing in line with the published emission factors (Carslaw et al. 2011). On-road vehicle testing in the UK has highlighted that the problem is primarily related to NOx emissions from diesel cars remaining relatively static (Carslaw & Rhys-Tyler, 2013). So are ...

  • AQE 2015 a great success for ET!

  • Delivering Climate Change Act could halve UK air pollution

    Meeting the UK’s Climate Change Act commitments could cut nitrogen dioxide (NO2) air pollution by 50-60%, leading to improved public health and longer life expectancy. That is according to a first-of-its-kind study by researchers at King’s College London, who set out to investigate the potential health benefits of delivering government policy. The Climate Change Act requires ...

  • Ozone and particulates most serious air quality problems in Europe

    Air quality in Europe has improved between 1990 and 2009, as emissions of most pollutants have fallen, according to a new report from the European Environment Agency (EEA). But there is still a lot of room for improvement, as many EU countries are expected to exceed the emissions ceilings in 2010 for at least one pollutant. In addition, concentration levels of ground-level ozone and particulate ...

  • AQMesh can complement air quality models, reference and indicative data sources
