Greenhouse gas emissions values
GHGEs (expressed as kg COTo maximise consistency across LCA methodologies used, two-thirds of GHGE values were obtained from one main source, ClimateHub from CarbonCloud [For some FFQ items, an adjustment to the reported GHGE value was necessary to ensure that the GHGE values for all FFQ items were calculated to the same system boundary (For each participant, daily intake (in kg) of each FFQ item was multiplied by the GHGE value determined for the item (in kg CO
