4. SPF Clean Air – Background
 Atmospheric pollution in the UK is responsible for approximately 40,000 early deaths and has a cost
of around £20 billion to health services and business, per year.
 The UK is entering a transformative period in air quality, as transport, heating, energy, solvent use
and agricultural emissions change. Most of the 'easy wins' to reduce particulate matter, volatile
organic compounds, ammonia and nitrogen oxides have already been implemented in the UK.
 Future improvements will require innovative solutions underpinned by new research to protect the
health of society, whilst pursuing clean growth and increasing national productivity.

5. To bring together the UK’s world
class air quality research base and
support high quality multi- and
inter-disciplinary research and
innovation to develop practical
solutions to today’s air quality
issues and equip the UK to
proactively tackle future air
quality issues, in order to protect
health and support clean growth.
SPF Clean Air – Aims

6. Strategic Priorities Fund
The Strategic Priorities Fund (SPF) is being led by UKRI to:
 drive an increase in high quality multi- and interdisciplinary
research and innovation
 ensure that UKRI’s investment links up effectively with
government research priorities and opportunities
 and ensure the system responds to strategic priorities and
opportunities
SPF builds on Paul Nurse’s vision of a ‘common fund’, to support
high quality multidisciplinary and interdisciplinary research
programmes, which could have otherwise been missed through
traditional funding channels

7. SPF Clean Air - Delivery
The Clean Air programme is jointly delivered by the Natural Environment Research Council (NERC)
and the Met Office, with the Economic and Social Research Council (ESRC), Engineering and
Physical Sciences Research Council (EPSRC), Innovate UK, Medical Research Council (MRC),
National Physical Laboratory (NPL), Science & Technology Facilities Council (STFC), Department for
Environment, Food and Rural Affairs (Defra), Department for Health and Social Care (DHSC),
Department for Transport (DfT), Scottish Government and Welsh Government.

8. Wave 1 - Clean Air: Analysis & Solutions
Developing solutions to air pollution to help policymakers and businesses protect health and work
towards a cleaner economy. (£20.5m)
Wave 2 - Clean Air: Addressing the Challenge of the Indoor/Outdoor Continuum
The programme aims to equip the UK to proactively tackle new air quality challenges related to
changing emissions and exposure patterns, in order to protect human health and support clean
growth. (£22m)
SPF Clean Air – Two Waves

9. Wave 1 - Clean Air:
Analysis & Solutions
AIMS
 Developing solutions to air pollution to help policymakers and businesses protect health and work
towards a cleaner economy
 Drive forward new multidisciplinary research and innovation
 Leverage existing UK investments and enable a challenge-focussed multidisciplinary community
to work together for the first time
 Inform implementation of the Clean Air Strategy and related strategies
 Develop new solutions to reduce emissions and protect public health, whilst avoiding perverse
consequences

10. Professor Sir Stephen Holgate Dr Gary Fuller
Clean Air Champions
 The Champions will bring together the UK’s world-class air quality research base to develop
practical solutions for air quality issues.
 “The Clean Air projects will create the foundation for interdisciplinary research to understand and
tackle air quality issues, drawing on the existing strengths of the UK’s world-class research base.
This is a timely programme that will enhance our capability to respond to current and future threats
to public health and build a more resilient, cleaner economy”
Dr Suzanne Bartington

11. Wave 1 - Clean Air:
Analysis & Solutions
OUTPUTS
 Clean Air Champions to maximise links across the programme, knowledge exchange, business
convening, and links into international efforts, and start to refine the priorities for future investment
 Innovation funding competition for UK businesses with solutions to work on product and service
development, and first deployments of technologies to tackle non-exhaust and non-road-vehicle air
pollution
 Activities to network and leverage existing UKRI major, long-term strategic investments in order to
support multidisciplinary policy-relevant research to underpin sustainable solutions for air quality
 Activities to develop a systems framework for clean air analysis

12. Wave 2 - Clean Air:
Addressing the Challenge of the Indoor/Outdoor Continuum
BACKGROUND
 The scientific, technical, behavioural and policy approaches used to assess and manage exposure
to air pollution need radical change to reflect the indoor/outdoor continuum of exposure.
 Human exposure to air pollution occurs in the home, at school and in workplaces, whilst travelling,
and during leisure activities.
 Managing human exposure to the very smallest airborne particulate matter (PM1 and ultra-fine PM)
and the complex cocktail of volatile organic compounds (VOCs) is likely to grow in health
significance as concentrations of larger primary particles (e.g. PM10 and nitrates from tailpipe Nox)
decline.
 Indoor air quality is dynamic: the introduction of new emissions in the indoor environment together
with the trend towards more energy efficient buildings (impacting insulation/ventilation) will increase
indoor air exposures.
 It will no longer be effective to attempt to manage public health impacts solely through controlling
outdoor sources.

13. Wave 2 - Clean Air:
Addressing the Challenge of the Indoor/Outdoor Continuum
THE SECOND WAVE OF THE CLEAN AIR PROGRAMME IS EXPECTED TO:
 Build a new UK interdisciplinary community to address research challenges across the interface of
indoor/outdoor air quality through collaboration between wider disciplines and stakeholders
including: environmental, social and medical sciences, engineering, economics, and health.
 Deliver new knowledge that:
 provides critical foresight on emerging air pollution challenges and associated health risks and impacts;
and
 enable an increased understanding and quantification of human behavioural change and practices in order
to develop and assess interventions, that limit harmful exposure to mitigate the negative health impacts of
individuals most at risk.
 Provide consistent, evidence-based advice for stakeholders through open data and tools in order to
stimulate policy and regulatory innovation.
 Stimulate business-led innovation for sustainable products and services to protect health across the
indoor/outdoor air quality interface and grow UK businesses.

14. OUTPUTS
 Networks to build the interdisciplinary community
 Interdisciplinary research and innovation consortia to generate new knowledge and tools to
influence policy and regulation
 Business-led innovation projects to develop a new clean air products and services for indoor
environment
 Continued coordination, integration and impact activities (including Clean Air Champions)
