Scope 1: what are the different categories?

Summary

Scope 1 is a central element of a company’s carbon footprint, focusing on the direct greenhouse gas emissions it generates. it breaks down into several categories, including stationary, mobile, industrial process and fugitive emissions.
Accurate classification of these emissions is crucial for optimizing reduction strategies, reinforcing corporate credibility, ensuring regulatory compliance and avoiding errors in carbon footprint calculations.

Introduction

To face today’s climate challenges, organizations and companies need to assess their carbon footprint. this carbon footprint encompasses several scopes and categories. scope 1 is one of the central elements of this carbon footprint and its proper understanding allows organizations to effectively reduce their GHG emissions. in this article, discover the different categories of Scope 1 and their challenges for companies.

Scope 1 categories

What is scope 1?

Scope 1 is one of the key perimeters of the carbon footprint. this scope refers to the direct greenhouse gas emissions generated by the activities of a company or organization. these emissions come from sources controlled or owned by the organization.

Unlike scope 2 and 3, which concern indirect emissions, scope 1 focuses exclusively on what the company emits directly, such as:

What are the different categories of scope 1?

Scope 1 is broken down into various categories, each representing a specific type of direct greenhouse gas (GHG) emissions.

Stationary emissions

Stationary emissions arise from the combustion of fuels in organizations’ stationary facilities, such as boilers, furnaces, or generators. for example, a factory that uses a furnace to process raw materials or a company that heats its premises in winter generates stationary emissions. the amount of gas emitted depends on the type of fuel used and the efficiency of the equipment.

Mobile emissions

Mobile emissions arise from the combustion of fuels in vehicles or mobile equipment owned or controlled by the company. this includes company cars, trucks, company planes, boats, and even some types of heavy machinery used on construction sites. every trip, and every liter of fuel consumed contributes to these emissions.

Industrial processes

In addition to combustion, some industrial activities directly emit greenhouse gasses, due to chemical or physical reactions. for example, cement production releases carbon dioxide when limestone is heated. these emissions are not directly related to the energy but to the process itself.

Fugitive emissions

Scope 1 also takes fugitive emissions into account. this refers to emissions that escape during the production processes or use of certain equipment. they are not intentionally released examples include refrigerant gas leaks from air conditioning or natural gas systems in pipeline infrastructure. even though they may seem minor, these emissions can have a significant impact on the environment, as some gasses have a high global warming potential.

Other specific categories

Some industries may have emissions sources specific to their field, such as emissions from solvent use agriculture, for example, generates emissions related to the enteric fermentation of ruminants or animal waste management while some organizations resort to the use of biomass fuels, such as wood. the combustion of biomass generates emissions that should be taken into account in the calculation of scope 1. it is crucial to correctly identify and categorize these emissions for an accurate carbon footprint assessment.

Identifying the different scope 1 categories is essential for reducing carbon emissions

Scope 1: the challenges of the different categories

Accurately classifying scope 1 emissions is more than just an administrative formality. indeed, this categorization has many issues:

Accurately classifying scope 1 emissions is more than just an administrative formality. indeed, this categorization has many issues:

Accurate categorization not only ensures the accuracy of carbon footprint data but also plays a key role in determining a company’s strategy and stakeholder positioning

Thus, it is advisable to surround yourself with experts or to use carbon footprint software such as the carbon footprint calculation software d-carbonize, in order to carry out a correct and accurate assessment of scope 1 emissions serving as a basis for informed decision-making.
