DEFRA Emissions types by industrial process

This category contains data on the greenhouse gases - or groups of greenhouse gases - which are typically emitted in association with particular industrial processes. The advice originates from the UK government department DEFRA, as published in their most recent greenhouse gas (GHG) conversion factors documentation.

The information relates specifically to processes in operation in the UK and emissions may differ slightly in other jurisdictions.


Limstone use

The 'limestone use' option refers to usage of limestone in Flue Gas Desulphurisation (FGD) and processes such as those in the glass industry. Not all uses of limestone release CO2.

Fletton brick manufacture

The 'fletton brick manufacture' option is specific to Fletton brick manufacture at the mineral processing stage, a process that uses clay with high organic content. Other types of brick manufacturing in the UK do not release Greenhouse Gases during the processing stage.
