Scope 3 emissions are often-overlooked yet largest source of indirect greenhouse gas emissions in a value chain. Imagine trying to solve a puzzle without knowing what half the pieces look like. That’s what it feels like for companies managing their carbon footprint without addressing these Scope 3 emissions. 

On average, Scope 3 emissions account for a whopping 70 to 90 % of a company’s total carbon footprint. This includes indirect emissions generated throughout the entire value chain, from sourcing raw materials to product disposal. 

While Scope 1 and 2 emissions (direct and energy-related) are relatively straightforward to measure, Scope 3 emissions are a maze of complexities, spanning supplier operations, product lifecycles, and customer use. The lack of visibility and reliable data makes it one of the most challenging—and critical—steps in any sustainability journey. In this guide, we’ll break down Scope 3 emissions in simple terms, explore why they matter, and share actionable steps to help you tackle them effectively.

What Are Scope 3 Emissions?

Let’s talk about Scope 3 emissions, the hidden part of your carbon footprint that many businesses struggle to wrap their heads around. These emissions aren’t directly caused by your operations (that’s Scope 1) or tied to the energy you use (Scope 2). Instead, Scope 3 emissions come from everything else in your value chain—the big picture stuff that happens upstream and downstream. 

Think about the raw materials you buy, the trucks that deliver your products, and even the energy consumers use when they plug in or dispose of your product. That’s Scope 3. It’s like looking beyond your front yard and realizing the entire neighborhood contributes to your environmental impact. 

Examples of Scope 3 Emissions 
  • The emissions from growing and processing the crops you purchase. 
  • Fuel burned by trucks and ships moving your products around the globe. 
  • Waste generated in your supply chain or by your customers at the end of a product’s life.

Why Do Scope 3 Emissions Matter?

Scope 3 emissions often make up the biggest chunk of a company’s total carbon footprint—sometimes 70% or more. Ignoring them is like fixing a leaky faucet while a pipe bursts in the basement. 

Tackling Scope 3 emissions isn’t just about compliance or reducing risks. It’s about building a sustainable business for the future. Consumers want to trust the brands they buy from, and investors are increasingly scrutinizing companies’ environmental impacts. Addressing Scope 3 emissions can be your competitive edge—and a step toward meaningful climate action. 

By understanding and addressing Scope 3 emissions, you’re not just reducing your footprint; you’re leading your industry into a more sustainable future.

Key Categories of Scope 3 Emissions

Scope 3 emissions cover a wide range of activities that happen up and down your value chain—essentially, everything you don’t directly control but still play a part in.  

  1. Purchased Goods and Services

Every product or raw material you buy has a backstory. Think about the energy used to grow, harvest, mine, or manufacture those items. From crops to machinery, the emissions from these processes fall under this category. For example, if you’re in the food industry, the carbon footprint of your grains, spices, or packaging materials counts as part of Scope 3. 

  1. Business Travel and Employee Commuting

When employees hop on a plane for a meeting or drive to work, those trips generate emissions. Even though you’re not behind the wheel or piloting the plane, these emissions are linked to your operations. Tracking and reducing them—like encouraging remote meetings or carpooling—can help lower your overall footprint. 

  1. Waste Generated in Operations

Ever wonder where that leftover packaging or manufacturing scrap ends up? The emissions created from transporting, processing, or landfilling your waste also fall under Scope 3. Minimizing waste or finding ways to recycle can make a significant difference. 

  1. Transportation and Distribution

How do your products reach stores or customers? Whether it’s by truck, ship, or plane, the emissions from moving goods are part of this category. Efficient logistics and sustainable transportation options can reduce this impact. 

  1. End-of-Life Treatment of Products

What happens to your product when customers are done with it? If it ends up in a landfill or incinerator, those emissions are yours to account for. Designing products that are easier to recycle or have a longer life can make a big impact here. 

By understanding these categories, you can identify where your biggest Scope 3 challenges lie—and start making meaningful changes to reduce your footprint! 

Upstream (Supply Chain-Related Emissions) 

The upstream facet of Scope 3 emissions is a exploration into the environmental impact woven intricately throughout the supply chain. From the extraction and production of raw materials to the transportation of goods, organizations are faced with the challenge of understanding and mitigating emissions at every juncture. As globalization tightens its grip, the need to navigate the complexities of upstream emissions becomes not just a choice but a necessity for sustainable practices. 

Downstream (Emissions from Product Use and Disposal) 

Downstream emissions usher us into the realm of the product life cycle, where the environmental narrative extends into the hands of consumers. Energy consumption, emissions, and waste generated during the use of products create a downstream ripple effect. Organizations must broaden their perspective to encompass the entire life cycle of a product, addressing its creation, utilization, and ultimate disposal or recycling. 

Other Indirect Emissions 

Beyond the traditional realms, Scope 3 extends its reach to encompass a myriad of indirect emissions. Business travel, employee commuting, and investments—each contributes to the complex tapestry of an organization’s environmental impact. These emissions, although not directly controlled, remain integral to the overall operation. Recognizing and categorizing these diverse sources provide a more comprehensive and nuanced picture of an organization’s environmental footprint. 

Managing Scope 3 emissions is one of the toughest challenges businesses face today. These emissions come from a wide range of activities across the value chain, and tackling them can feel like an uphill battle. Let’s break down the key hurdles businesses face in simple terms:

Challenges in Measuring Scope 3 Emissions

Data Collection Issues

Getting accurate data on Scope 3 emissions is like piecing together a complex puzzle—but some pieces are missing or don’t fit. 

  • Inconsistent or incomplete supplier data: Suppliers often lack the tools or processes to track their emissions. One supplier might send detailed reports, while another might not track emissions at all. 
  • Fragmented systems: Data comes in different formats, from spreadsheets to emails, making it difficult to consolidate and analyze. 

This lack of uniformity leaves businesses guessing, and relying on assumptions can lead to inaccuracies.

Lack of Transparency

Most companies only have visibility into their immediate (Tier 1) suppliers. Beyond that, it’s a black box. 

  • Difficulty engaging suppliers: Many suppliers are hesitant to share emissions data due to fears of being penalized, a lack of resources, or not understanding the value of transparency. 
  • Deep supply chains: Tracking emissions from Tier 2 or Tier 3 suppliers (e.g., raw material producers or transport providers) requires significant effort. 

Without open collaboration, businesses face blind spots in their emissions reporting.

Resource Constraints

Managing Scope 3 emissions can be expensive and time-consuming. 

  • High costs: Manual tracking methods or hiring consultants to map the supply chain and gather data can quickly add up. 
  • Lack of in-house expertise: Many companies don’t have dedicated teams with the technical knowledge needed for accurate emissions tracking. 

For smaller businesses or those with complex supply chains, this becomes a daunting financial and operational burden. 

Regulatory Pressure

Governments and regulatory bodies are introducing stricter requirements for emissions disclosures. 

  • EUDR (EU Deforestation Regulation): Companies must prove that their supply chains are deforestation-free, adding another layer of compliance complexity. 
  • CSRD (Corporate Sustainability Reporting Directive): Larger businesses in Europe must report detailed sustainability metrics, including Scope 3 emissions. 

Falling short on these requirements risks hefty fines, reputational damage, and loss of market access. 

Complex Supply Chains and Limited Visibility Beyond Tier 1 Suppliers

Most companies work directly with a limited group of suppliers—known as Tier 1. These are the partners they communicate with directly, such as raw material providers or manufacturers. However, Scope 3 emissions often stem from deeper layers of the supply chain (Tier 2, Tier 3, and beyond). For instance: 

  • A company sourcing chocolate may know its direct cocoa supplier but may not have insight into the farms where the cocoa is grown or the emissions generated during farming and transport. 
  • Each layer adds complexity, making it difficult to trace all contributors to carbon emissions. 

Without robust mechanisms for visibility, companies struggle to piece together the full picture of their supply chain emissions. 

Reliance on Third-Party Data and Assumptions

Tracking emissions requires data—lots of it. But not every supplier has the tools, knowledge, or willingness to share detailed emissions data. This forces companies to: 

  • Rely on averages or estimates: Instead of precise numbers, companies often use industry averages, which can lead to inaccuracies. 
  • Depend on third parties: Emission factors or databases provided by external organizations are often used, but these are generalized and may not reflect the unique characteristics of a company’s supply chain. 

For example, if a logistics company calculates emissions based on a standard fuel efficiency rate, it may miss variations caused by old vehicles or longer-than-expected transport routes.

Lack of Standardized Measurement Tools or Methods

There’s no one-size-fits-all approach to calculating Scope 3 emissions. Different industries, regions, and companies follow varying standards, creating inconsistency. Challenges include: 

  • Diverse reporting frameworks: While frameworks like the GHG Protocol provide guidance, companies still face ambiguities in categorizing and quantifying emissions. 
  • Incompatible tools: Suppliers and businesses might use different tools or software that don’t communicate well with one another, complicating data integration. 

This lack of standardization leaves companies navigating a fragmented system, leading to incomplete or unreliable data. 

Why Measuring Scope 3 Emissions Is Essential

Alignment with Global Sustainability Goals

Supply chain decarbonization is a critical aspect of tackling Scope 3 emissions, which represent the indirect emissions within a company’s value chain, such as those from suppliers, logistics, and product use. 

According to the Science Based Targets initiative (SBTi), the number of companies setting science-based targets for Scope 3 emissions has increased by 250% since 2019. This surge indicates a growing commitment to tackling the full range of climate impacts. 

The world is increasingly focused on reducing carbon emissions to fight climate change. Companies are expected to align their practices with global sustainability frameworks like the Science-Based Targets initiative (SBTi). By measuring Scope 3 emissions, you’re not only meeting these targets but also contributing to global efforts to limit global warming. It shows that you’re committed to playing your part in a sustainable future, which is crucial for both your reputation and the planet. Achieving a net-zero supply chain requires reducing these emissions through sustainable sourcing, carbon offsetting, and enhanced supply chain transparency. 

Regulatory Compliance

Regulatory requirements are tightening, especially when it comes to emissions reporting. The EU’s Corporate Sustainability Reporting Directive (CSRD) and the EU Deforestation Regulation (EUDR) are examples of laws that require companies to report on their environmental impact, including Scope 3 emissions. Failing to track and disclose these emissions can result in non-compliance, potential fines, and a damaged reputation. By measuring Scope 3 emissions, you stay ahead of the regulations and ensure your business operates within the law. 

Building Consumer and Investor Trust

In today’s world, consumers and investors care deeply about sustainability. They’re more likely to trust companies that openly report their environmental impact and show efforts to reduce their carbon footprint. By accurately measuring and reporting Scope 3 emissions, you demonstrate transparency and accountability, which builds consumer loyalty and attracts investors who prioritize sustainability. It shows that your company is serious about reducing its environmental impact, which can be a powerful differentiator in a competitive market. 

Identifying Opportunities for Cost Savings and Operational Efficiencies

Measuring Scope 3 emissions helps you identify inefficiencies within your supply chain. By tracking emissions across your value chain, you may uncover areas where waste is high, energy use is excessive, or transportation is inefficient. This insight can drive cost savings by optimizing operations and reducing waste. Additionally, adopting more sustainable practices (like switching to greener suppliers or reducing packaging) can lower your costs in the long run while benefiting the environment. 

Tools and Strategies for Tackling Scope 3 Emissions
