Design outcomes

Primary

MeasureTime frame
Environmental impact of purchases, measured by the mean environmental impact score (taken across standardised values for the four environmental indicators listed below) for purchased products from hot meal categories in each worksite cafeteria for the period of interest. The outcome will be calculated from sales data, recorded via electronic point-of-sale tills throughout the 12 weeks of the study, combined with data on the environmental impact of each food option.

Secondary

MeasureTime frame
1. Total energy (kcal) purchased from hot meal categories in each worksite cafeteria, calculated from sales data recorded via electronic point-of-sale tills throughout the 12 weeks of the study, combined with data on the energy content of each food option. 2. Nutrient content (total fat [% energy purchased], saturated fat [% energy purchased], protein [% energy purchased], and fibre [g/100g]) of purchases from hot meal categories in each worksite cafeteria throughout the 12 weeks of the study – if possible to obtain nutrient data. 3. Total weekly revenue (£GBP) from each cafeteria, based on sales data recorded via electronic point-of-sale tills throughout the 12 weeks of the study 4. Total number of transactions per week in each cafeteria, based on sales data recorded via electronic point-of-sale tills throughout the 12 weeks of the study
