1. Pollution can affect the human body in many ways. Pollutants, especially fine particulate matter, appear to be able to penetrate deep into human organs via our circulatory systems. Whilst there are significant uncertainties around the mechanics of causation, application of the precautionary principle and our awareness of health effects urge us to take further action to deal with air pollution. The evidence base is developing globally and in Scotland and careful consideration is needed to shape public health policy and the messages to be deployed, including the strategy for sensitive receptors and how messages are conveyed to the public. There may ultimately be no such thing as a minimum safe level and we need to reduce pollution and protect the public from sources generally.

2. The LAQM system has the potential to drive further significant improvement. The report sets out LAQM recommendations in the Governance section and practical responses for local government in particular to deliver better performance in the Placemaking and Local Government section.

3. Targeting ammonia abatement, in relation to emissions from fertiliser, digestate and animal husbandry types.

42. There is potentially an all-users dimension to this issue as well as heightened risk for vulnerable passengers or drivers as well as Health and Safety and employment law dimensions for bus, haulage and other business employers if drivers are potentially exposed to dangerous pollution. This may be an issue likely to benefit from a collaborative research approach.

43. This would assess the home environment where someone might experience relatively clean air for 9-18 hours per day, through a commute by bike, car, bus, train or on foot, to a relatively clean or air conditioned work environment or school through a return commute and an evening in a public or private environment or in a street café with passing traffic and so on. Real exposures could be highly diverse and both peak pollution impacts and longer-term cumulative exposures could be relevant to health impacts, subject to prior health state and risk factors. Whilst highlighting the complexity of the situation, such work would offer assessment of boundary conditions for future policy effort.  This could also offer ideal opportunities for collaborative, multi-disciplinary international research.

79. Dec 2024 is a critical environmental compliance date including concerning LEZ full implementation. The National Infrastructure Commission for Scotland will be making recommendations for the period from 2024 and we would expect the National Transport Strategy in its next form as well as the Investment Plans that follow will shape road network developments. In terms of the current Infrastructure Investment Plan, it would seem that the A9 and A82 project should be (largely) complete. Consideration would have to be given to dualling the A96 and potentially other intercity routes previously identified as strategic commitments. Examination of regional benefits and projects already in the Infrastucture Investment pipeline will be needed.

81. The NSL (Nationaal Samenwerkingsprogramma Luchtkwaliteit) is a statutory programme that coordinates the Dutch government’s work on air quality. It requires all levels of Dutch government to work together to carry out air quality improvement duties. The objective of the NSL is to deliver compliance with air quality standards and to ensure that development does not adversely affect current and future compliance. The NSL has created a national model of air quality, similar to the planned regional NMF set out in CAFS, however the NSL approach also coordinates the collation of traffic data, which is the big limitation to the development of the regional NMF. In addition the NSL identifies early in the planning process any spatial developments that could potential make a significant contribution to air pollution through scale and increased traffic-related effects. This results in direct requirement to include mitigation measures to maintain or improve air quality before approval can be granted. The model used within the NSL is developed and maintained centrally, built using robust traffic data, emission and air quality monitoring data. The model is updated annually to take account of new monitoring (air and traffic) data and developments/mitigation measures.

98. Current powers emanate from EA95 and require Ministerial permission. Delegation of this power would streamline procedure and hasten improvement.

99. Some have already dubbed what needs to happen next as CAFS2. This is possible of course but a simpler or new brand might arguably be better.

100. Given recent developments as well as legitimate locus, SOLACE and CoSLA engagement would be vital. This could be supplemented too by periodic input from REHIS, SCOTS, HOPS, etc. as well as those best placed in the reformed Public Health Scotland arrangements.
