Why is this important?
Inhalers account for 3-4% of the whole NHS carbon footprint. Of this, Metered dose inhalers (MDIs) use hydrofluoroalkanes (HFA) propellants which are potent greenhouse gases, 1000 – 3000 times more potent than carbon dioxide. In the UK approximately 70% of inhalers used are MDIs which is much higher than many other European Countries.
Climate change is one of the biggest challenges to health in medium and long-term and the consequences are likely to be wide and diverse.
Overuse of SABA inhalers, in asthma, is associated with increased risk of exacerbation and mortality as well as contributing hugely to the NHS carbon footprint. The RCP ‘National Review of Asthma Deaths’ report published in 2014 highlighted the dangers of SABA overprescribing. Of the patients whose deaths were investigated, 36% had been prescribed 12 or more SABA inhalers in the previous 12 months.
