Scope 1 Emission
Scope 1 emissions are direct greenhouse gas (GHG) emissions that occur from sources that are controlled or owned by an organization. These include emissions associated with fuel combustion in boilers, furnaces, vehicles, and other equipment, as well as accidental or fugitive emissions like chemical and refrigerant leaks and spills.
Common Sources of Scope 1 Emissions
Some major sources that generate Scope 1 emissions include:
- Stationary Combustion (e.g. boilers, furnaces)
- Mobile Combustion (e.g. vehicle fleets)
- Process Emissions (e.g. chemical production, cement manufacturing)
- Fugitive Emissions (e.g. equipment leaks, refrigerant losses)
Measuring and Reporting Scope 1
Companies calculate their Scope 1 emissions based on site-specific data like fuel consumption, miles traveled, chemical production output, etc. Emission factors are used to convert this data into metric tons of carbon dioxide equivalent (CO2e). Common methodologies for quantifying Scope 1 include:
- The GHG Protocol Corporate Standard
- EPA Center for Corporate Climate Leadership
- ISO 14064 for GHG inventories
Importance of Scope 1 Disclosures
Accurately measuring and reporting Scope 1 emissions demonstrates accountability and transparency. It enables companies to identify hotspots, set targets, and track performance over time. Scope 1 is a core component of comprehensive GHG inventories and reporting to initiatives like CDP.

What are scope 1, 2 and 3 carbon emissions?
Scope 1 covers emissions from sources that an organisation owns or controls directly – for example from burning fuel in our fleet of vehicles (if they’re not electrically-powered).

Explaining Scope 1, 2 & 3
Direct GHG emissions occur from sources that are owned or controlled by the company, for example, emissions from combustion in owned or controlled boilers, furnaces, vehicles, etc.; emissions from chemical production in owned or controlled process equipment. Direct CO2 emissions from the combustion of biomass shall not be included in scope 1 but reported separately. GHG emissions not covered by the Kyoto Protocol, e.g. CFCs, NOx, etc. shall not be included in scope 1 but may be reported separately.
