Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, with reference to the Government's press release entitled Government launches world leading plan to tackle air pollution, published in 14 January 2019, what the evidential basis is for the statement that agriculture is responsible for 88% of ammonia emissions.

The data used in compiling this statistic are 2016 figures from the UK National Atmospheric Emissions Inventory (NAEI) which is available via the uk-air.defra.gov.uk website. The NAEI reports emissions of air pollutants from all sources including the agriculture sector.
