AQ and Public Health law
6
• The importance of Public Health Law lies in meeting the needs of the individual and the population for good health, including Environmental Protection
• House of Commons Environmental Audit Committee sixth report (Action on AQ. 2014-2015) confirms the impact of poor AQ on both human health and the Treasury
www.portsmouth.gov.uk7
Latest reviews strengthen evidence linking air pollution to ill-health (carcinogenic, adverse effects on the respiratory, cardiovascular systems, the nervous system, infant mortality rates, on pre-term birth and on cognitive performance in children).

AQ and health inequalities
9
• Most disadvantaged areas suffering from non-
communicable diseases coincide with Air Quality
Management Areas
• The most disadvantaged communities experience
poor health outcomes as a result of both lifestyle and
environmental factors
www.portsmouth.gov.uk10
• International/ European/ National/
• Local Authority/ individual action
Responsibility for deliveringcleaner air?
Local Authority responsibility• Local Air Quality Review & Assessment
• Take a strategic approach• Foster partnership working with others
• Promote community engagement through educating and provision of incentives /
disincentives• Show leadership
• Regulation of some sources of air pollution
www.portsmouth.gov.uk11
AQAP aims
• Non traffic related measures (background
emissions)
• Traffic related measures – Transport schemes
• Public Information – Enforcement – Public transport
patronage
• Policy / Technology
AQAP delivery tools
• Cars – Reduce use, reduce congestion and fluidity
• Buses – Increase patronage – improve technology
• HGV – Re-route, consolidate, avoid congestion

Traffic, Environment & Community Safety Scrutiny PanelObjective
To understand the Local Air Quality Management Process and its implication locally http://data.hampshirehub.net/attachment/jsna/portsmouth-jsna/social-and-environmental-context/environment/cab20130701r4app
Recommendations
– Consider transferring the financial responsibilities for LAQ monitoring and assessment to the Public Health team
– Produce a new local Air Quality Strategy– Cabinet Member for Environment & Community Safety
continues to monitor the progress made on measures set out in the National Air Quality Strategy.

Local Air Quality Action Plan measure
Can road traffic management control system improve local air quality?
It’s a pioneering project (never before carried out at such a large scale)

Road traffic model

• Peak periods 0700-1000, 1200-1400 and 1600-1900
• Traffic signal specifications
• Public transport routes
• Three scenarios for each Corridor:
Do Minimum
Do something 1
Do something 2

Operational assessment summary
22
• Improvements have been identified within all Corridors that predict operational benefits
• It is recommended that the identified preferred schemes are considered further
www.portsmouth.gov.uk
ORTMCS preliminary conclusions
23
• All recommended scenarios in theory should lead to improvements in AQ
• The significance of predicted AQ improvements yet to be determined
• The predicted AQ improvement is likely to be marginal in most corridors
• Most of the corridors are fairly constrained in terms of physical measures that can be applied
