Scope 3 emissions: Reduction made easy

Sustainability and climate protection are key issues for companies worldwide today. Pressure on companies to reduce their emissions is growing due to global climate targets, regulatory requirements, and increasing customer demand for sustainable products.

A central part of this process is understanding a company's own Scope 3 emissions. While many companies keep track of their direct emissions (Scope 1) or indirect emissions from purchased energy (Scope 2), Scope 3 emissions often remain a black box. Yet they often account for 70–75% of a company's total emissions and are therefore the biggest lever for climate protection measures.

Emissions along transport routes, during production, and from the use of products by customers are particularly relevant. Companies that create transparency in this area and make targeted optimizations can significantly improve their carbon footprint.

In this article, we explain what Scope 3 emissions are, why they are so crucial for companies, and how their analysis can be implemented in practice.

Scope meaning: Scope 1, Scope 2, and Scope 3

Before we delve deeper into Scope 3 emissions, it is worth taking a quick look at the classification according to the Greenhouse Gas Protocol (GHG Protocol):

Scope 1

This includes all direct emissions from own production processes, company vehicles, or heating systems.

Scope 2

These are indirect emissions from purchased energy, e.g., electricity, heat, or steam.

Scope 3

All other indirect emissions along the entire value chain, from suppliers to transport and production to the use and disposal of products by customers.

Scope 3 is particularly complex because companies cannot directly control these emissions. Nevertheless, they are crucial for the carbon footprint and often the biggest lever for reducing the overall CO₂ balance.

Knowledge of Scope 3 emissions is now also a key criterion for ESG ratings and sustainability reports. Companies that systematically record these indirect emissions demonstrate that they are taking responsibility along the entire supply chain.

What are Scope 3 emissions?

Scope 3 emissions include all indirect emissions that occur outside a company's direct sphere of influence but are caused by its business activities. These include, for example:

• Manufacture of raw materials and products by suppliers

• Transport of goods from the manufacturer to the customer

• Use and disposal of products by end customers

Scope 3 emissions are particularly relevant for industrial and commercial companies because they account for the largest share of total emissions. While Scope 1 and Scope 2 emissions are often easy to measure, Scope 3 emissions pose a challenge. They require data from the entire supply chain and cooperation with partners and suppliers.

Companies that understand and actively manage Scope 3 can make strategic decisions for sustainable products, energy-efficient processes, and optimized logistics.

Focus on the most important Scope 3 categories

Of the 15 categories in the GHG Protocol, three areas are particularly crucial for many industrial companies: transport, production, and product use. These categories have the greatest impact on the carbon footprint and, at the same time, offer the greatest scope for reduction measures.

1. Transport & Logistics

Transport activities along the supply chain cause significant emissions, both upstream (from the supplier) and downstream (to the customer).

• Emission drivers: Diesel and truck journeys, ship or air transport, inefficient route planning

• Measurement: CO₂ emissions per kilometer, per mode of transport, and per unit transported

• Practical example: A global industrial company can significantly reduce emissions by switching from air freight to rail or sea transport

• Advantage of digital tools: Dashboards such as the Line Up Supply Chain Dashboard enable real-time visualization of transport emissions, route optimization, and scenario analyses

2. Production

The manufacture of raw materials and products by suppliers also causes Scope 3 emissions. Energy-intensive processes such as metal processing, chemical production, and plastics manufacturing are particularly relevant here.

• Emission drivers: Energy consumption in production facilities, use of materials, manufacture of semi-finished products

• Measurement: Activity-based calculation or based on purchasing costs (spend-based)

• Practical example: Companies can reduce emissions by favoring suppliers that use renewable energy or promoting energy-efficient production methods

3. Use of products

Scope 3 emissions arise not only before or during production, but also as soon as customers use the products. Particularly energy-intensive devices, machines, or vehicles cause a significant carbon footprint during their use.

• Emission drivers: Electricity consumption, maintenance, consumables

• Measurement: Life cycle analysis of products, frequency of use, energy requirements

• Practical example: Energy-efficient machines or devices with a longer service life significantly reduce the Scope 3 footprint

Calculation and monitoring of Scope 3 emissions

The recording of Scope 3 emissions is complex, but crucial for a realistic carbon footprint. Companies must collect data along the supply chain, analyze processes, and systematically calculate emissions.

Calculation methods

• Activity-based: Calculation based on specific activities, e.g., kilometers driven, energy consumption of suppliers, use of materials

• Spend-based: Estimation of emissions based on purchasing volume and industry-specific emission factors

Digital tools

Software solutions such as the Line Up Supply Chain Dashboard enable companies to visualize Scope 3 emissions during transport in a transparent manner and make targeted optimizations. Advantages of digital tools:

• Automatic calculation of emissions along transport routes

• Collection of production and raw material data from suppliers

• Scenario analyses to simulate reduction measures

• Integration into sustainability and ESG reports

By using digital tools, companies can not only accurately determine their carbon footprint, but also derive strategic decisions for sustainable supply chains.

Conclusion

Scope 3 emissions are the key lever for companies seeking to improve their carbon footprint. Transportation, production, and use account for the largest share of these emissions and also offer the greatest opportunities for reduction.

With a systematic approach to data collection, calculation, and optimization, supported by digital solutions such as the Line Up Supply Chain Dashboard, companies can not only improve their carbon footprint, but also meet regulatory requirements, save costs, and make their supply chains sustainable. Companies that understand and actively manage Scope 3 thus secure environmental and cost advantages in an increasingly climate-conscious economy.
