Air quality assessment in Camden

A baseline matched to the site

Start with the site layout and the question the assessment must answer. Review monitoring location, height, year, completeness and nearby sources. A roadside measurement may not describe an upper-floor courtyard or an air intake.

Camden’s air quality evidence page provides council reports and monitoring information. Its current action-plan gateway lists the 2023–2026 Clean Air Action Plan. Keep the report edition and measurement year explicit when choosing data.

Operational assessment and design

Bring the proposed uses, floor levels, ventilation strategy and plant details into the same evidence package. Where modelling is needed, document the inputs and assumptions. Then test practical changes while the layout can still respond.

Air Quality Neutral and Positive

Check these as separate workstreams alongside the impact assessment. Our London air quality guide explains the wider planning framework, with links to adopted GLA guidance. Its Neutral and Positive evidence planner helps organise the information for that review.

A usable monitoring brief

Record who receives alerts, how equipment is checked, how data are reviewed and what happens when an action level is reached. The brief should connect a measurement to a practical response, including inspection and a record of corrective action.

Local Plan 2017 — Policy CC4: Air quality

Policy CC4 addresses both emissions from development and exposure of its occupants. Its purpose is to reduce air pollution impacts through assessment and mitigation. Sensitive uses such as homes and schools need a design that addresses poor air quality.

Read CC4 alongside A1: Managing the impact of development, as identified in the validation list. Depending on the scheme, C1 (health), A3 (biodiversity), CC1 (climate mitigation) and T1–T4 (transport) also inform the brief.

Adopted Local Plan, 3 July 2017 — CC4, printed pages 269–270

Air Quality CPG — adopted January 2021

This supplementary planning document explains CC4. Use sections 3–5 for assessment scope, emissions controls and conditions. Paragraphs 3.5–3.7 address conservative modelling, cumulative effects, generators and exposure; paragraph 4.10 covers construction monitoring.

Record the chosen background data and future-year assumptions explicitly. The CPG asks for a conservative approach to future emissions and backgrounds. Resolve any departure when agreeing the modelling method.

Local validation list — November 2025

The council’s validation gateway dates its current list to 20 November 2025. The air quality entry sits on pages 19–20. Check the proposal against this list and the separate assessment webpage before submission.

Supporting guidance includes Amenity and Planning for Health and Wellbeing. Check any neighbourhood plan and site-specific planning brief applying to the address, particularly where land uses, construction or sensitive neighbours need coordination.

Validation requirements and supporting documents

Manual B and the design checklist

Camden still links Manual B: reducing air pollution in new developments. It explains how energy demand, heating choices and controls affect emissions. It dates from 2013, so read its practical design principles alongside current policy and technical standards.

The 2019 planning checklist connects transport, CHP, occupant exposure, dust controls and Air Quality Neutral evidence. Coordinate the energy and ventilation designs with the AQA; identify missing plant specifications clearly.

London Plan SI 1 and current London guidance

Policy SI 1: Improving air quality sits alongside Camden’s policies. Use the February 2023 Air Quality Neutral guidance for its current scope, benchmarks and simplified routes.

Some Camden documents retain older London policy numbers and technical references. For London-wide requirements, use the current guidance linked in our London policy guide. Air Quality Positive is a separate design approach for relevant large-scale proposals, not a label earned by passing a Neutral calculation.

Emerging Local Plan — October 2026 consultation

The council announced Main Modifications on 12 October 2026, with consultation closing on 23 November. The replacement plan remains emerging at this review. Check its stage and any relevant weight at the application date; do not confuse its policy numbering with adopted CC4.

Camden examination updates

What is changing beyond Camden?

London: the Draft London Plan remains emerging. Its general consultation deadline was 15 October 2026. Track the examination and final adoption before treating proposed changes as adopted requirements.

England: Defra’s interim PM2.5 planning guidance encourages attention to emissions and exposure. The July 2026 target delivery plan distinguishes statutory 2040 targets from interim 2030 objectives. Explain how design reduces exposure and emissions; national targets do not themselves decide an individual application.

Technical guidance: the IAQM register lists revisions to land-use planning, construction dust and construction monitoring guidance in progress. Use the latest published edition until a final replacement appears, then review the implications for the project.
