This bulletin provides baseline figures on the current Inhaler Carbon Footprint at ICS level in the North of England, in order that systems can identify the level of response to be undertaken. It examines the current carbon footprint attributed to Inhalers in the North East and Yorkshire and the North West. It also analyses the Inhaler carbon footprint by therapeutic class, Inhaler type, and the contribution of hospital admissions for asthma towards total Inhaler carbon footprint.
