Scope 1 covers the direct emissions that your company generates while performing its business activities. This includes stationary combustion generated at company facilities, mobile combustion from company controlled vehicles, and fugitive emissions.

This article gives you a short introduction to the different categories of scope 1. If you are a Normative Business user, looking for details on how to collect data for this scope, go to the data collection page.

Stationary combustion

Stationary combustion emissions can come from any kind of combustion engine machinery operated at a company's facilities. This includes:

• electricity, heat, or steam from, e.g., boilers and turbines;
• manufacture or processing of chemicals and materials;
• own waste processing in, e.g., furnaces.

Mobile combustion

This category includes the direct emissions generated by transport of materials, products, and waste in vehicles controlled or owned by the company. The emissions arise from all fuel usage in water, land, air and rail transport.

Fugitive emissions

These emissions result from intentional or unintentional releases, e.g., equipment leaks from joints, seals, packing, and gaskets; methane emissions from coal mines and venting; hydrofluorocarbon (HFC) emissions during the use of refrigeration and air conditioning equipment; and methane leakages from gas transport.

Process Emissions

These are direct greenhouse gas emissions from industrial processes that chemically or physically transform materials, rather than from combustion. They typically result from chemical reactions that release GHGs as a byproduct. Examples include emissions from cement production, ammonia production, or the manufacturing of certain chemicals where the process itself releases CO2 or other GHGs.
