Scope 1, 2, and 3 Explained, Simply 👌
What Are Scope 1, 2, and 3 Emissions? An Overview
Scope 1, 2, and 3 emissions are key categories of greenhouse gas (GHG) emissions that companies need to measure and manage for effective sustainability. Here’s an overview of each scope:
Scope 1 Emissions: Direct Carbon Footprints of Businesses
Scope 1 emissions are direct emissions that come from sources a company owns or controls. These emissions are the most visible and easiest to measure since the organization is directly responsible for them. Examples include the combustion of fossil fuels in company-owned vehicles or machinery, on-site energy production (like using a diesel generator), chemical processes in manufacturing (such as cement production), and fugitive emissions, like refrigerant leaks from air conditioning units.
Scope 2 Emissions: Indirect Carbon Impacts From Energy Use
Scope 2 emissions are indirect emissions from the generation of electricity, heat, steam, or cooling that a company purchases and uses. These emissions occur at the energy producer’s facilities, not within the company itself, and reflect the company’s reliance on external energy sources. Examples include emissions from the electricity grid powering company buildings or purchased steam or district heating systems.
Scope 3 Emissions: The Full Value Chain of Carbon Accountability
Scope 3 emissions are indirect emissions from a company's value chain, both upstream (from suppliers) and downstream (from customers). They are the most complex and often make up the largest portion of total emissions. Upstream examples include raw material extraction, transportation, and business travel, while downstream examples include product use, waste disposal, and distribution.
Why Understanding Scope 3 Emissions is Crucial for Sustainability
Scope 3 emissions are important because they come from all parts of a company’s value chain. This includes emissions from suppliers, transportation, how products are used, and waste disposal. For many companies, especially in consumer goods, Scope 3 makes up 70-90% of total emissions. These emissions are harder to track and reduce because they involve many different groups, but working together with everyone in the supply chain is key to managing them.
How to Measure Scope 1, 2, and 3 Emissions Effectively (Carbon GPT)
Carbon GPT is committed to simplifying the measurement of Scope 1, 2, and 3 emissions. Our platform helps companies tackle this often overwhelming process with ease. Here's how to get started:
- Understanding the Emissions Categories
Scope 1 emissions come from direct company-controlled activities, like fuel combustion in owned vehicles or facilities. Scope 2 emissions stem from purchased energy, such as electricity or steam. Scope 3 emissions are all other indirect emissions from the value chain, including supplier operations, transportation, and product use.
- Preparing Your Data
For Scope 1, gather data on fuel consumption in facilities, vehicles, and equipment, including data on refrigerants and any process-related emissions. For Scope 2, collect records of electricity, heat, or cooling purchased, and identify the energy provider’s emission factors for your region. For Scope 3, map your value chain to identify key emission sources and collect data from suppliers, logistics providers, and product lifecycle stages.
- Input Data into Carbon GPT
Carbon GPT allows you to upload your raw data into the relevant categories (fuel, energy, transport). The platform uses automated calculations and standardized emission factors (such as those from IPCC or regional databases) to estimate emissions. Additionally, Carbon GPT can integrate with supply chains, allowing suppliers to directly input their data, simplifying Scope 3 tracking.
- Verification and Refinement
Ensure data accuracy by comparing results to past records or benchmarks. Carbon GPT’s reporting tools can flag anomalies or gaps, and involving stakeholders such as suppliers and logistics partners helps validate Scope 3 inputs.
- Reporting and Action
Carbon GPT generates detailed reports with insights and visuals for internal and external reporting, compliant with the GHG Protocol and other frameworks. Use the data to set reduction targets and focus on areas with high emissions, such as transitioning to renewable energy for Scope 2 or partnering with low-carbon suppliers for Scope 3.
Why Use Carbon GPT?
Carbon GPT simplifies the process of calculating emissions, automates data integration across multiple sources, and provides actionable insights for reducing emissions. By combining your raw data with our platform’s tools, you can effectively measure emissions and focus on meaningful sustainability initiatives.
Conclusion
Scope 3 emissions cover all indirect emissions in a company’s value chain, like those from suppliers, transportation, product use, and waste disposal.
Together with Scope 1 (direct emissions) and Scope 2 (emissions from bought energy), they show the full carbon footprint. Scope 3 is often the biggest part, but tools like Carbon GPT make it easier to measure and take action for sustainability.
