AQC's Sister Company, Logika Consultants, is Sponsoring the Built Networking Webinar "Sustainable Development and Green Infrastructure"

AQC Analysis Isolates Changes in Pollutant Concentrations at 247 Sites Across the UK as a Result of COVID-19

AQC has further updated its analysis of the impacts of COVID-19 social and travel restrictions on air quality.  Trends in raw NOx, NO2 and O3 concentrations in 2020 to date continue to show no obvious influence of the social and travel restrictions implemented in response to the COVID-19 pandemic. However, isolating and removing meteorological and temporal effects has revealed significant reductions in NOx and NO2 concentrations at a very large number of monitoring sites across the UK. 


AQC Analysis Identifies Substantial Reductions in Roadside Pollutant Concentrations as a Result of COVID-19 Social and Travel Restrictions

Air Quality Consultants Ltd has updated its analysis of the impacts of COVID-19 social and travel restrictions on air quality. Where other published analysis has compared concentrations measured during two separate time periods without consideration of confounding factors such as meteorology, this analysis has sought to isolate some of the variation caused by meteorology from the measured ambient concentrations, and has demonstrated a substantial reduction in roadside NOx and NO2 concentrations.


AQC Investigates the Effect of COVID-19 Social and Travel Restrictions on UK Air Quality

Air Quality Consultants Ltd has analysed trends in air quality over the year to date to investigate whether the recently implemented COVID-19 social and travel restrictions have influenced air quality across the UK.  No obvious influence has been identified as yet, but the analysis will be updated over the coming days/weeks/months to establish whether effects become apparent.


Defra’s Emission Factor Toolkit now Matching Measurements

Air Quality Consultants Ltd has demonstrated that reductions in NOx emissions from motor vehicles predicted by Defra’s Emission Factor Toolkit now broadly match measured data at roadside monitors.  This means Air Quality Consultants’ CURED model is no longer required.


Air Quality Consultants & Noise Consultants Launch New Environmental Strategy Practice

Logika Consultants has been launched as a sister company to Air Quality Consultants and Noise Consultants.  Environmental assessment and strategy expert, Toby Gibbs, will be the Managing Director. 


Air Quality and Biodiversity Conference

Air Quality Consultants is contributing to CIEEM Spring Conference on ‘Assessment and Mitigation of Air Quality Impacts on Biodiversity’ on 4 March 2020


Ammonia Emissions from Roads for Assessing Impacts on Nitrogen-Sensitive Habitats

AQC has examined evidence relating to ammonia emissions from road traffic, their contribution to roadside nitrogen deposition, and how this might change in the future.  AQC has also created a new emissions tool for traffic-related ammonia, which can be downloaded for use by others.


NOx Trends in the UK 2013 to 2019

AQC has updated its analysis of nitrogen oxides concentrations trends at road, urban and rural sites across the UK to include 2019


AQC contributes to EIA Handbook

AQC provides advice on air quality and EIA in a new edition of the EIA Handbook.


AQC announces the appointment of Tim Williamson

AQC announces the appointment of Tim Williamson as an Associate Director in the London office.  Tim has 25 years’ experience in environmental policy development, focussing on air quality, having operated at the local, national and international scales.
