Archived gridded data 

These datasets are not the most recent version. Please see the Download emission maps for the latest data.

These are provided as published each inventory year and haven’t been updated since. For example, the 2010 gridded data have not been updated since publication of the 2010 national inventory version.

As our methodologies and data sources are continually evolving, the time series of maps are not directly comparable and we would advise against doing so.
