Understanding Scope 1, 2, and 3 emissions is essential in managing your company's carbon footprint. Terms like "Scope 1, 2, and 3 emissions" frequently arise in discussions about sustainability, but what do they actually mean, and why should businesses care?
This comprehensive guide will help you navigate these concepts and provide actionable steps to reduce your company's environmental impact.
What are carbon emissions?
Before diving into the specifics of Scope 1, 2, and 3 emissions, let's briefly recap what carbon emissions are. Carbon emissions refer to the release of greenhouse gases (GHGs) like carbon dioxide (CO₂) and methane (CH4) into the atmosphere. These gases trap heat, contributing to global warming and climate change. Businesses contribute to carbon emissions in various ways, from direct activities like burning fossil fuels to indirect activities like purchasing electricity. By understanding the sources and impact of these emissions, businesses can take effective measures to reduce their carbon footprint.
Scope 1 Emissions
Direct Emissions
Scope 1 emissions are the direct emissions from sources that are owned or controlled by the company. This includes emissions from combustion in boilers, furnaces, vehicles, and chemical production from owned or controlled process equipment.
Scope 1 Examples:
- On-site Fuel Combustion: Emissions from burning natural gas in heating systems.
- Company Vehicles: Emissions from fuel used in company-owned vehicles.
- Industrial Processes: Emissions from chemical reactions during manufacturing processes.
Scope 2 Emissions
Indirect Emissions From Purchased Energy
Scope 2 emissions are the indirect emissions from the generation of purchased energy, such as electricity, steam, heating, and cooling consumed by the reporting company. While these emissions occur at the energy producer’s facility, they are accounted for in the company’s GHG inventory because they result from its energy use.
Scope 2 Examples:
- Purchased Electricity: Emissions generated by power plants that produce the company's electricity.
- Purchased Heating and Cooling: Emissions from external facilities that provide heating or cooling services.
Scope 3 Emissions
Scope 3 emissions are all other indirect emissions that occur in the value chain of the reporting company, both upstream and downstream. These emissions often represent the largest portion of a company’s total GHG emissions.
Upstream Emissions
Category 1. Purchased Goods and Services
Emissions from producing goods and services the company buys cover all upstream emissions.
Category 2. Capital Goods
Emissions from producing long-lasting goods like machinery and buildings used by the company.
Category 3. Fuel and Energy-Related Activities

Scope 1, 2, and 3 Emissions Overview
GHG Inventory of Scope 1, 2, and 3 Emissions
This graphic visually represents the Scope 1, 2, and 3 greenhouse gas emissions inventory by illustrating the upstream, downstream, and direct activities within a company's carbon footprint.
- Scope 1 (Direct): The central arrows highlight company facilities and company vehicles, which are direct emission sources under the company’s control.
- Scope 2 (Indirect): The image shows energy use (purchased electricity, steam, heating, and cooling) that contributes to indirect emissions from energy production.
- Scope 3 (Indirect): Surrounding Scope 1 and 2, the circular pathway illustrates both upstream (e.g., purchased goods, capital goods, transportation, business travel) and downstream (e.g., use of sold products, end-of-life treatment, investments) activities. This captures the emissions outside the company’s immediate operations but connected through the supply chain and product life cycle.
The diagram also shows various greenhouse gases (CO₂, CH₄, N₂O, HFCs, PFCs, SF₆) that contribute to climate change, further emphasizing the wide-reaching impact of Scope 1, 2, and 3 emissions on the environment.
Scope 1, 2, and 3 Emissions Categories
This image breaks down the different categories of greenhouse gas (GHG) emissions based on the Scope 1, 2, and 3 Emissions classifications.
- Scope 1 includes direct emissions from company-owned or controlled sources such as company facilities and company vehicles. These emissions are categorized as upstream, meaning they occur early in the company's operations.
- Scope 2 accounts for indirect emissions from the generation of purchased energy, specifically purchased electricity, steam, heating, and cooling for the company’s own use. These are upstream as well.
- Scope 3 includes both upstream and downstream indirect emissions. Upstream activities, such as the production of purchased goods and services, capital goods, and employee commuting, are related to what the company buys or the services it uses. Downstream activities focus on emissions generated after products leave the company, including transportation and distribution, the use of sold products, and end-of-life treatment for those products. Scope 3 is the broadest and most indirect type of emission, often involving the supply chain and product lifecycle.
