Emission mitigation plans

Practical, proportionate air quality mitigation strategies developed in consultation with your design team and local planning authority. We translate assessment findings into clear, enforceable site management requirements that protect air quality without impeding programme.

What is an emission mitigation plan?

An emission mitigation plan (EMP) — sometimes called an Air Quality Management Plan (AQMP), Dust Management Plan (DMP) or Construction Air Quality Management Plan (CAQMP) — is a site-specific document specifying the practical measures a developer, contractor or operator will implement to control air quality emissions from a development. It is typically required as a planning condition or as part of a Construction Environmental Management Plan (CEMP). Viridian Air prepares standalone EMPs and air quality chapters for CEMPs, drawing on the findings of our air quality assessments and construction dust risk assessments to specify measures that are proportionate to the identified risk and realistic to implement on site.

Getting mitigation right first time. Poorly written EMPs — those that list generic measures without site-specific rationale — are often rejected or returned with conditions by planning officers. Our EMPs are written as genuinely enforceable site management documents with clear responsibilities, monitoring requirements and trigger thresholds.

What an EMP covers

The content and depth of an EMP depends on the scale and sensitivity of the scheme. A well-structured EMP typically includes:

  • Site description, key risks and sensitive receptors
  • Dust and emission control measures for each construction phase
  • Wheel-wash, road sweeping and vehicle management requirements
  • Haul route specification and traffic management for dust control
  • Stockpile management and soil handling procedures
  • Site monitoring programme: real-time dust monitors, trigger levels, action protocols
  • Non-road mobile machinery (NRMM) emission standards and inventory requirements
  • Complaint response procedure
  • Named responsible person and reporting frequency.

Operational mitigation

For operational phases — particularly schemes with combustion plant, HGV traffic or industrial processes — we prepare operational air quality management plans covering:

  • Combustion plant specification and maintenance requirements
  • Vehicle routing and idling restrictions
  • Green travel plans and electric vehicle charging provision
  • Stack monitoring and reporting obligations under Environmental Permits
  • Complaint investigation and response protocols

Frequently Asked Questions

Where a construction dust risk assessment identifies medium or high risk at any receptor, an emission mitigation plan is always required. For low-risk schemes, many local authorities accept a brief statement of good-practice measures rather than a full standalone EMP. We advise on the appropriate level of detail for your specific scheme and local authority requirements.
