The SAT-S allows you to estimate the carbon and energy footprint of a digital service (that you use or provide) based on 1 year of use of the service assessed. This will help you make informed decisions about actions to improve your energy efficiency and eventually become greener in your ICT elements.
The SAT-O allows you to estimate the carbon and energy footprint of your ICT organisation or the IT department of your organisation, based on 1 year of activity. This will help you make informed decisions about actions to improve your energy efficiency and overall carbon emissions, either directly linked to the company activities or not (e.g. business travel and commuting of your staff).
