Researchers at Cambridge University have said some of the UK's 58 asthma sufferers could switch their inhalers from metered-dose varieties – which contain greenhouse gases – to more sustainable versions. The move would have the same environmental impact as becoming vegetarian, the team said. Replacing one of every 10 metered-dose inhalers would reduce carbon dioxide (CO2) equivalent emissions by five million kilotonnes. The scientists said patients who needed the metered-dose inhalers should not switch, but could ensure every puff counted by having their technique assessed.
