Scope 1 emissions are direct greenhouse gas emissions (such as carbon dioxide or methane) from sources that are owned or controlled by your organisation. This can be the combustion of fuels in boilers or vehicles, emissions from chemical production processes, and emissions from owned or leased refrigeration equipment. The GHG Protocol defines the following emission categories as part of Scope 1 emissions:
Stationary combustion
Mobile combustion
Processing (currently not supported)
Fugitive emissions
If you intend to report your emissions based on a particular standard or framework, measuring Scope 1 emissions is typically required.
