Air Quality

Air pollution can be a critical consideration for development projects. Changes in air quality, dust and odour levels can have a significant impact on the health of surrounding communities and ecosystems. We are experienced in meeting and mitigating these challenges and our experts can help our clients to find ways to maintain compliance with regulatory requirements at the lowest possible cost. 

Providing workable solutions to complex issues

We evaluate the impacts of new developments on the surrounding environment and site suitability and advise on the options for proportionate mitigation. 

We identify significant compliance concerns and integrate the fundamental technical and regulatory aspects of facility operations into business decision making.

Our approach is based on upfront consultation with the local planning and permitting authority and regulators, utilising best practice methods of assessment and robust responses to any post-submission queries. This means our clients benefit from enhanced prospects for obtaining planning permission and other consents.
