The UK population collectively breathes out about 1,100 tonnes of the greenhouse gases methane and nitrous oxide every year. That’s one key finding from our new research.
Those breath emissions are a mere 0.05% and 0.1% of the UK’s total human-generated emissions of the two gases respectively. Their overall contribution to the country’s collective carbon footprint of course pales in comparison to fossil fuel burning and other major sources of emissions.
