I have been compiling information on odour emission rates for some years. These have been complied from publicly available reports on the internet, planning portals or in published reports. If you wish any data to be removed, please contact me through this website. As far as I am aware, this is the only publicly available odour emission datbase in the UK.
The database is updated regularly and is available here, note I am gradually editing the spreadsheet to have consistent formatting of units.
I always welcome new data to include in this database.
