AIR QUALITY ASSESSMENT
Air quality affects us all, and there is extensive evidence to show that poor air quality has substantial health implications, affecting the respiratory and cardiovascular systems. This has been recognised through various legislative acts, which has in turn influenced both national and local planning policy. As a result, air quality assessments are frequently requested by local authorities to support planning and environmental permit applications.
Air quality assessments can come in several forms such as an Air Quality Exposure Assessment or an Air Quality Impact Assessment. Furthermore, Air Quality Assessments may contain additional components for instance: an Emission Mitigation Statement, Air Quality Neutral Assessments and Air Quality Dust Risk Assessments.
EMISSION MITIGATION STATEMENT
An Emission Mitigation Statement outlines measures and strategies specific to a development that will be implemented to mitigate emissions. Damage cost calculations frequently accompany emission mitigation statements to indicate the level of mitigation required to offset emissions generated by a development.
Dust emissions are generated by various sources and pose a potential health hazard to individuals exposed to them. Additionally, dust may accumulate on nearby surfaces, resulting in unsightly fouling. To address these concerns, Dust Assessments have been introduced to identify and manage the impact of these emissions on their surroundings. These proactive measures serve to minimise potential harm to public health and protect the aesthetic integrity of surrounding areas.
AIR QUALITY NEUTRAL ASSESSMENT
The Air Quality Neutral Assessment was introduced by the London Plan and aims to reduce emissions by requiring that development proposals must be Air Quality Neutral. Developments are assessed in relation to two benchmarks: Building Emission Benchmark (BEB) and Transport Emission Benchmark (TEB). When NOx and PM10 emissions from a proposed development fall below these benchmarks, it is considered air quality neutral.
