1. Executive Summary

​

Non‑Road Mobile Machinery (NRMM)—including generators, construction plant, mobile compressors, and temporary power systems—represents one of the largest unregulated sources of particulate matter (PM) and NOx emissions in urban environments.

​

London’s NRMM Low Emission Zone has demonstrated that a structured compliance scheme can reduce NRMM emissions by 40–60% within three years.

​

This proposal outlines a potential North West NRMM Scheme, delivered by Cybrand AEC Ltd, providing:

​

• Regional consistency

• Practical enforcement

• Industry engagement

• Emissions reduction

• A clear pathway to cleaner construction

​

2. Why the North West Needs an NRMM Scheme

​

Key Drivers

​

• Air Quality Management Areas (AQMAs) across the combined authorities in Cheshire, Merseyside, Manchester, Lancashire and Cumbria.

• High density of construction, regeneration, and infrastructure projects

• Increasing use of diesel generators and temporary power

• Lack of any current regional NRMM compliance framework

• Alignment with UK Net Zero 2050 and local authority climate action plans

 

 

Impact Without Intervention

​

• NRMM emissions can contribute up to 10% of local NOx levels in construction‑heavy zones

• Diesel generators often run 24/7, producing disproportionate emissions

• No current mechanism to ensure modern, cleaner Stage V plant is used

• No regional database of machinery, emissions, or compliance

​​

3. Proposed Scheme Structure

​

3.1 Governance Model

​

Local Authorities (LA Group)

• Policy ownership

• Integration with planning conditions

• Enforcement powers (Environmental Protection Act, planning enforcement)

​​

Cybrand AEC Ltd (Delivery Partner)

​

• Operational delivery

• Site inspections

• NRMM register administration

• Contractor engagement

• Compliance reporting

• Technical guidance

​​

This simplifies the Greater London Authority (GLA) model, whilst still delivering tangible results.

​​

5. Scheme Components

​

5.1 NRMM Emission Standards

​

Modify the proven London model, with adaptations tailored for the North West construction demographic:

• Stage IV minimum for most plant

• Stage V for generators and high‑impact machinery

• Exemptions only where justified and approved​

​

5.2 NRMM Register

​

Cybrand will operate a regional register:

• All construction sites logged

• All machinery declared

• Emissions standards verified

• Compliance tracked

​​

5.3 Site Inspections

​

Cybrand inspectors will:

​

• Visit sites across the region

• Check machinery plates, serials, and emissions data

• Identify undeclared sites

• Support enforcement actions

​

5.4 Planning Integration

​

Local authorities can adopt:

• Standard NRMM planning conditions

• Requirements for NRMM declarations

• Compliance checks at discharge of conditions

​

6. Benefits to Local Authorities

​

Environmental Benefits

​

• Significant reductions in PM and NOx

• Cleaner air for residents

• Alignment with climate action plans​

​

Operational Benefits

​

• No need for councils to build internal expertise

• Consistent regional enforcement

• Independent, specialist inspections

• Clear compliance pathways for developers

​​

Economic Benefits

​

• Encourages modern, efficient plant

• Reduces fuel consumption

• Supports transition to hybrid/BESS temporary power

• Creates a level playing field for responsible contractors

​​

7. Implementation Roadmap

​

Phase 1 – Setup (0–3 months)

​

• LA partnership agreements

• Scheme governance

• Register deployment

• Contractor communications

​

Phase 2 – Rollout (3–12 months)

​

• Begin inspections

• Start compliance reporting

• Planning condition integration

• Regional contractor workshops

​​

Phase 3 – Full Operation (12+ months)

• Quarterly emissions reporting

• Enforcement support

• Scheme refinement

• Expansion to neighbouring authorities

​
