SIX has commissioned Carbon-Connect, a company specializing in carbon footprint and offsetting, with analyzing three common types of invoicing: paper invoices, e-mail invoices and eBill. The aim of the study was to assess how much greenhouse gases are emitted by each procedure, and thus to determine to what extent partially or entirely digital processes can reduce the environmental footprint and help protect the environment.
Even today, there are still billions of invoices sent per year in Switzerland, most of them by mail. Based on the calculations performed as part of the sustainability study, around 63,222 tons of CO2 equivalents were emitted in 2021. This corresponds to the carbon footprint of 4,215 of the Swiss that includes their consumer behavior, mobility, habitation and eating habits.

A payment flow that is completely digitalized with eBill reduces the carbon footprint significantly. SIX estimates that around 80% of all invoices will be sent with eBill by 2028. This will make a difference: if the number of invoices stays the same, the CO2 emissions will be reduced by 66%.

The data reference and detailed calculations of the emissions for the respective invoicing processes can be found in the “Sustainability in Invoicing” report by SIX.
