Emissions generated during the product use phase are determined by two main factors:

The energy required by the equipment to run, and the location and source of the energy. Keep in mind that different energy grids will yield different carbon emissions depending on the production method (renewable, coal, nuclear, etc.). Many companies are working to make products more energy efficient in order to reduce by 2030, the absolute scope 3 GHG emissions associated with the use of sold products.

Similar product configurations will have comparable energy draw regardless of use location. However, energy sourcing decisions, like variations in the power grid and the electricity source that customers are using, impact the carbon emissions associated with the products. For example, a product plugged into a grid largely dependent on fossil fuels will have higher carbon emissions compared with that of a product plugged into a grid powered by solar or nuclear energy.
