Health Outcomes from Stationary Sources Tool (HOST)

Air pollution causes ill health and in turn places demand on the NHS. The sources of air pollution often go unnoticed as they come from many significant sources, such as cars and gas boilers. The Health Outcomes from Travel and Transport Tool (HOTT) was launched in 2019, to help NHS organisations quantify and report on the scale of air pollution from travel and transport. This is now joined by a second tool specifically measuring the impact of stationary sources such as gas boilers, electricity generation and waste incineration.

Use the Health Outcomes from Stationary sources Tool (HOST) to quantify the Quality Adjusted Life Years lost from air pollution emissions from heat and power used on NHS sites. Test out scenarios for reducing your organisation emissions and prioritise reducing air pollution which has a direct health impact.

Use the tool to:

  • Support business cases for improving your energy sources (e.g., switching to renewable electricity) and energy saving measures
  • Provide information to support staff and community engagement on turning off unused electrical equipment and lights and closing doors to keep the heat in. 
  • Engage suppliers from tender stage to consider the environmental impact of energy using equipment. 
  • Using HOST to evaluate the success of past/current travel and transport initiatives
The NHS Long Term Plan sets out clear targets for the NHS to reduce air pollutant emission.

DEFRA damage cost information has been combined with Estates Return Information Collection (ERIC) data and there are multiple years of Trust data in the tool such as staff (FTE), and floor area.

Scenarios can be created by overwriting the appropriate section and quantify the change in air pollution from different interventions.
