There are various scopes to consider.

Scope 1: the fuels you burn on site to generate heat/cooling or electricity.

Scope 2: the electricity you import on site probably burns carbon so it has a carbon factor you can find that on your utilities website (most likely). Imported electricity in kWh x carbon factor tCO2e/(delivered)kWh = emissions in tCO2e - you may want to start here with the location, grid electricity and expected electricity use.

Scope 3: are the emissions made off site to make materials that are imported on site to make the business run.

There are no hard rules to do this analysis. Most of it is a linear approximation. Most people don’t publish analysis beyond scope 1/2.

It’s really important to list assumptions and sources. Good luck.
