Design outcomes

Primary

MeasureTime frame
Environmental impact of purchases: Measured by the mean environmental impact score for purchased products across a week in each worksite cafeteria. The outcome will be calculated from sales data recorded via electronic point-of-sale tills throughout the 12 weeks of the trial, combined with data on the environmental impact of each food option.

Secondary

MeasureTime frame
1. Impact on revenue: Measured by the total weekly revenue (£GBP) from each cafeteria, based on sales data recorded via electronic point-of-sale tills throughout the 12 weeks of the trial 2. Impact on transactions: Measured by the 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 trial 3. Health impact: Measured by total energy (kcal) purchased weekly in each worksite cafeteria (controlling for the total number of transactions), calculated from sales data recorded via electronic point-of-sale tills throughout the 12 weeks of the trial, combined with data on the energy content of each food option
