Scope 1, 2, and 3 Emissions for Companies: Understanding Their Impact and Role in Sustainability

Emissions from companies have a significant impact on the environment and global climate change. To better understand and measure these emissions, the Greenhouse Gas (GHG) Protocol has created a three-level categorization system, known as Scope 1, 2, and 3 emissions. Understanding these categories is important for companies looking to reduce their carbon footprint and become more sustainable.


How are the different Scopes being categorized?

Scope 1

Scope 1 emissions are direct emissions from a company's operations. This includes emissions from combustion of fuels such as natural gas, oil, and coal, as well as emissions from company vehicles and equipment.


Scope 2

Scope 2 emissions are indirect emissions from the generation of energy used by the company. This includes indirect greenhouse gas emissions from purchased or acquired energy, like electricity steam, heat production and emissions from cooling, generated off-site and consumed by a company.

Scope 3

Scope 3 emissions are all other indirect emissions that occur as a result of a company's activities, but are not owned or controlled by the company. This includes emissions from the production of goods and services purchased by the company, emissions from employee commuting, and emissions from the disposal or treatment of waste generated by the company.



How to reduce Scope 1, 2, and 3 emissions?

Reducing emissions from all three Scopes is important for companies to become more sustainable and tackle climate change.


Scope 1

To reduce Scope 1 emissions, companies can switch to cleaner sources of energy, such as renewable energy or low-carbon fuels. They can also implement energy-efficient technologies, such as LED lighting and efficient HVAC systems, to reduce energy use and emissions.


Scope 2

To reduce Scope 2 emissions, companies can purchase renewable energy credits, or work with their energy suppliers to increase the proportion of renewable energy in the energy mix. They can also reduce their energy use through energy-efficient technologies and behaviors, such as turning off lights and equipment when not in use.


Scope 3

To reduce Scope 3 emissions, companies can work with their suppliers to reduce emissions in their supply chains, and they can also encourage employees to use more sustainable modes of transportation, such as public transportation or carpooling. Companies can also promote sustainable waste management practices, such as recycling and composting, to reduce emissions from waste disposal.


Companies have a crucial role to play in tackling climate change and reducing emissions. Understanding and reducing emissions from all three Scopes is essential to achieving sustainability and combating global warming. Companies that take a comprehensive approach to reducing emissions and adopt sustainable practices will not only help the environment, but they will also benefit from improved brand reputation, cost savings, and increased efficiency.
