Question to the Department of Health and Social Care:

To ask Her Majesty's Government what assessment they have made of the proportion of the NHS carbon footprint made by hydrofluorocarbon in metred dose inflators.

We have made no such assessment on the proportion of the National Health Service carbon footprint made by hydrofluorocarbon in metred dose inhalers or of the impact of the use of metred dose inhalers containing hydrofluorocarbons in releasing greenhouse gases. However, we are informed by NHS England that the National Atmospheric Emissions Inventory calculated the carbon emissions from inhalers in England as 850,000 tonnes of carbon dioxide equivalents. This is equivalent to approximately 4% of the entire carbon footprint of the NHS in England.
