Scope 4 Emissions Explained for Modern Businesses

When we talk about emissions, we usually think about a company’s carbon footprint. But what about the good they do? That’s where Scope 4 emissions come in.

Often called avoided emissions, this concept flips the script. It’s not about the pollution a company creates, but the pollution its products or services prevent from ever happening in the first place. Think of it less like a footprint and more like a positive carbon 'handprint'—the good you put out into the world.

Decoding the Concept of Avoided Emissions

Scopes 1, 2, and 3 are all about accounting for the emissions your business is responsible for, from the factory floor to your suppliers. Scope 4, on the other hand, looks outwards. It asks: how does our product help someone else lower their emissions?

This forward-thinking metric allows a business to measure its net positive contribution to a greener future. It’s a game-changer for companies built around sustainability, giving them a real way to quantify the environmental benefits baked into their innovations.

Shifting from Footprint to Handprint

To really get your head around Scope 4, you have to understand the difference between a carbon footprint and a carbon handprint. It's a simple but powerful distinction.

• Carbon Footprint (Scopes 1-3): This is the total sum of greenhouse gases your company is responsible for, directly or indirectly. The goal here is always reduction.

• Carbon Handprint (Scope 4): This measures the positive impact you create by helping customers slash their carbon footprints. The goal is to make this number as big as possible.

Let’s take an electric vehicle (EV) manufacturer as a perfect example. The company has its own footprint from building the cars—that’s its Scopes 1-3. But its Scope 4 impact is the colossal volume of emissions that don't spew out of a tailpipe every time someone drives their EV instead of a petrol car. To see this in action, the story of how EVs cut carbon emissions in Africa provides a fantastic real-world look at these avoided emissions.

By putting a number on these avoided emissions, companies can tell a much richer sustainability story. It’s not just about doing less harm; it’s about actively creating solutions for a low-carbon world.

This is especially meaningful in countries like the Czech Republic, where hitting climate targets is a top priority. In 2022, Czechia’s emissions were around 116.3 million tonnes of CO2-equivalent, which was a 2.3% drop from the previous year. Scope 4 provides a framework for innovative Czech firms to show exactly how their clean-tech solutions are helping drive that national progress, far beyond their own factory gates.

Comparing The GHG Scopes: A Clear Breakdown

To really get a handle on Scope 4, we first need to understand how it differs from the established Scopes 1, 2, and 3. While they all deal with greenhouse gases, their focus is worlds apart. It helps to think of them as different layers of a company's climate impact.

Scopes 1, 2, and 3 are all about measuring a company's carbon footprint – the total emissions an organisation is responsible for, both directly and indirectly. It’s an accounting of the negative climate impact.

Scope 4, on the other hand, measures a company's carbon handprint. This is the positive impact a business creates by helping other companies reduce their emissions. It’s a forward-looking metric that focuses on solutions, not just problems.

The Foundational Scopes: 1, 2, and 3

These three scopes are the backbone of corporate carbon accounting. Together, they create a full inventory of a company’s emissions, from its own operations right through its entire value chain.

• Scope 1: Direct Emissions. These are emissions from sources your company directly owns or controls. Picture the exhaust from your company’s delivery vans or the emissions from a manufacturing process on-site.

• Scope 2: Indirect Emissions. This scope covers the emissions from generating the energy you buy. It's the carbon footprint of the electricity, heating, or cooling you purchase from a utility provider to keep your lights on and your offices running.

• Scope 3: Value Chain Emissions. This is the big one. It's a catch-all for every other indirect emission in your value chain, from the production of raw materials you buy to your employees' daily commutes and what happens to your products at the end of their life.

This infographic gives a great visual overview of how to think about an impact assessment across your entire operation and supply chain.

As the image shows, a proper assessment has to look at the full lifecycle, from sourcing materials to final delivery. If you want to dig deeper into these categories, our detailed guide on the GHG Protocol explained for Czech businesses is a great place to start.

Scope 4 shifts the conversation from accountability for your own emissions (footprint) to demonstrating the positive climate contribution of your products (handprint).

This is a really important distinction. Reducing your Scope 1, 2, and 3 emissions is about responsibility and managing risk. Calculating your Scope 4 emissions, however, is about showcasing innovation, market value, and your strategic role in a low-carbon economy.

To make these differences crystal clear, let's break them down in a table.

Comparison of GHG Protocol Scopes

As you can see, the first three scopes are fundamentally about measuring an existing impact, while Scope 4 is about quantifying a potential, positive future impact created through your products or services.

How to Calculate Avoided Emissions Credibly

Figuring out your Scope 4 emissions can feel a bit abstract at first, but the idea behind it is actually quite simple. It all comes down to a comparison: what’s the difference in emissions with your product versus what they would have been without it?

This comparison rests on two scenarios: a baseline scenario (the "without you" picture) and the product scenario (the "with you" picture). The gap between these two is where you find your positive impact.

Scope 4 Calculation Formula: Baseline Emissions (Without Your Product) - Product Emissions (With Your Product) = Avoided Emissions

Think of it less like strict accounting and more like building a logical case, backed by solid evidence, for your product's environmental benefit.

Defining Your Baseline and Boundaries

This is the most important part of the entire exercise. You need to establish a believable baseline. This baseline is your "business-as-usual" case—it represents the emissions that would have happened if a customer chose a common, alternative solution instead of yours. If your baseline is weak or unrealistic, your entire claim falls apart.

Before you can do that, you have to define your system boundaries. This just means deciding which parts of the product’s life you’re going to look at for both your product and the baseline alternative. The key here is to be consistent so you're making a fair, apples-to-apples comparison.

For instance, if you sell high-efficiency LED lighting, your baseline would be the higher energy use and shorter lifespan of old-school incandescent bulbs. The product scenario, then, would model the lower energy consumption and longer operational life of your LEDs. For a closer look at this kind of lifecycle thinking, check out our guide on how to calculate the carbon footprint of a product easily and accurately.

Quantifying the Emissions Scenarios

With a clear baseline and product scenario in hand, it’s time to run the numbers. You’ll need to gather data and use emission factors to work out the total greenhouse gas output for both situations.

1. Quantify Baseline Emissions: First, you’ll research the typical emissions tied to the baseline product or service. This often means digging into industry reports, academic papers, or lifecycle assessment databases to find reliable figures for that standard alternative.
2. Quantify Product Emissions: Next, calculate the emissions from your own product’s lifecycle, making sure to stick to the same boundaries you set earlier. This covers everything from its use and maintenance right through to its end-of-life.
3. Calculate the Net Difference: Finally, subtract your product's total emissions from the baseline's total emissions. A positive number is your Scope 4 avoided emissions. Simple as that.

Let’s bring this home with an example. In the Czech Republic, CO2 emissions from transport shot up from 11,218 kt in 1990 to over 18,418 kt by 2017, even while the country’s overall emissions were dropping. A Czech company making lightweight materials for electric vehicles could calculate its Scope 4 impact here. They would show how their lighter materials reduce the car’s energy needs compared to standard, heavier materials, directly helping to tackle this growing emissions source.

A final, crucial point: transparency is everything. Always be upfront about your assumptions, data sources, and how you did your maths. This is what builds trust and keeps you clear of any greenwashing accusations.

Real World Examples of Scope 4 in Action

Theory is one thing, but seeing Scope 4 emissions in the wild really makes the concept click. Avoided emissions are happening all around us, usually thanks to companies whose entire purpose is to offer more sustainable ways of doing things. These real-world cases show just how powerfully a Scope 4 calculation can frame a story of positive environmental impact.

Take a classic example: a solar panel manufacturer. Of course, the company has its own carbon footprint from making and shipping its products (that's Scopes 1–3). But its Scope 4 contribution is the huge volume of greenhouse gas emissions avoided every time a home or business uses those panels to generate clean power instead of drawing from a fossil-fuelled grid. For a deeper dive, understanding what solar energy is helps clarify how it directly displaces higher-emission energy sources.

From Software to Supermarkets

The idea of avoided emissions isn’t just for the renewable energy sector. It stretches across an incredible range of industries, showing how innovation everywhere can contribute to a lower-carbon economy.

Here are a few diverse examples of Scope 4 in practice:

• Remote Collaboration Software: Think of a company that develops high-quality video conferencing tools. It helps its customers avoid the emissions that come from business travel. The baseline is the carbon cost of flights, car journeys, and hotel stays for face-to-face meetings. The alternative? A virtual meeting with almost zero emissions. That difference is a clear Scope 4 benefit.

• Plant-Based Foods: A brand that makes meat alternatives can calculate the emissions avoided by displacing conventional livestock farming. The baseline is the notoriously high carbon footprint of beef or dairy. The product scenario is the much lower footprint of plant-based agriculture, making the difference a powerful Scope 4 story.

• Lightweight Automotive Components: An engineering firm that designs lighter, stronger materials for electric vehicles (EVs) helps make them more efficient. The baseline is a standard EV with heavier parts that uses more electricity per kilometre. By cutting the vehicle's weight, the firm's components reduce its lifetime energy consumption, creating a measurable avoided emission.

By measuring their Scope 4 impact, these companies can shift the narrative from simply reducing their own negative footprint to actively increasing their positive handprint on the world.

This forward-thinking approach is exactly what sets apart the top companies leading in product carbon footprint transparency in 2025. They aren't just reporting their own emissions; they're demonstrating the wider societal benefit of their products.

This gives a much fuller picture of their role in tackling climate change, moving beyond simple compliance to showcase genuine environmental leadership.

The Strategic Value of Reporting Scope 4 Emissions

Most of the time, when we talk about carbon footprints—Scopes 1, 2, and 3—we're focused on risk management and accountability. It's a defensive game of measuring and reducing your company's negative impact.

Scope 4, on the other hand, is all about going on the offensive. It’s where your business stops just trimming its own emissions and starts proving its positive contribution to a low-carbon world.

Think of it as a strategic tool for storytelling. Reporting Scope 4 lets you build a powerful narrative around your products, turning what could be a dull compliance report into a genuine competitive edge. This kind of story really connects with today's environmentally-aware market, from individual shoppers to B2B procurement teams.

When you can put a number on the emissions your products help customers avoid, you’re giving them tangible proof of your brand's value. The conversation suddenly shifts from price and features to real, measurable environmental benefits.

Gaining a Competitive and Reputational Edge

In a packed market, a compelling Scope 4 story can set you apart. It signals to investors, partners, and customers that your company isn't just another part of the climate problem—it's an active part of the solution. This can directly sway purchasing decisions and open doors to capital from sustainability-focused investment funds.

This "carbon handprint" narrative is also fantastic for your brand's reputation. It builds trust by showing that your commitment to sustainability is designed right into the products you create. This forges a much stronger bond with stakeholders who are looking to partner with responsible, forward-thinking organisations.

While Scopes 1, 2, and 3 measure your operational footprint, Scope 4 highlights your innovation handprint. It's the metric that proves your business is built for a low-carbon future, turning sustainability into a key driver of growth.

Inspiring Teams and Driving National Progress

The benefits of Scope 4 reporting don't stop at the company's edge; they ripple inward. When employees can see a clear line connecting the products they design, build, or sell to a larger environmental purpose, it's incredibly motivating. It gives their daily work a sense of meaning, which helps boost morale and attract top talent who want their careers to count for something.

This has a wider impact on a national scale, too. In 2022, for instance, the Czech Republic reported 116.3 MtCO2-eq in total emissions. To hit its net-zero target by 2050, the country needs to make huge cuts.

Innovative Czech companies that can show significant Scope 4 contributions aren't just helping their own customers. They are playing a direct role in helping the nation bridge that gap and achieve its climate goals. You can find more details in this report on Czechia’s climate progress and goals.

In the end, getting to grips with Scope 4 is about seeing the opportunity. It reframes your entire climate strategy, moving it from a cost centre to a value creator. It’s how you align your commercial success with the urgent, global mission of decarbonisation.

Common Questions About Scope 4 Emissions

As more people start talking about Scope 4, a lot of good questions are popping up. It's a different way of thinking about emissions—looking forward instead of just at the current footprint—so it’s natural to want to get the details right. This is all about using this new metric effectively.

Let’s dig into some of the most common questions: who can actually claim these emissions, whether it's officially recognised, and what roadblocks you're likely to hit along the way. Getting these answers straight will help you avoid the usual traps.

Can Any Company Claim Scope 4 Emissions?

In a word, no. At least, not credibly. A genuine Scope 4 claim is really for companies whose whole reason for being is to help their customers cut GHG emissions. The product itself has to be the direct cause of the reduction when you compare it to what the customer would have otherwise used.

Think about a company that makes solar panels or develops software that optimises building energy use. It’s pretty clear-cut. Their products are designed to replace more carbon-intensive alternatives.

On the other hand, a business that sells standard office chairs would have a tough time making a convincing case. Sure, the chairs might be made from recycled materials—which is great for their own Scope 3 footprint—but the simple act of using the chair doesn't lower the customer's emissions.

Is Scope 4 an Official Part of the GHG Protocol?

Not right now, and this is a crucial point. It's important to remember that Scope 4 is not a formal category in the official GHG Protocol Corporate Standard, which is the rulebook for Scopes 1, 2, and 3. You should think of it as extra information, a way to add context about your company’s positive contribution.

Top-tier organisations like the World Resources Institute (WRI) have put out guidance on how to calculate these avoided emissions. But the golden rule is that you absolutely must report these numbers separately from your required Scope 1, 2, and 3 inventories.

The whole idea is to stop companies from using their positive 'handprint' (Scope 4) to hide or distract from their operational 'footprint' (Scopes 1-3). For real transparency, you have to report them as two separate things.

Keeping them separate gives investors, customers, and regulators a full and honest picture of a company's total climate story—both its part in the problem and its role in the solution. This distinction is everything when it comes to credibility.

What Are the Biggest Challenges in Reporting Scope 4?

The single biggest hurdle, without a doubt, is setting a credible and verifiable baseline. You have to define what would have happened if your product didn't exist, and that can get subjective fast. It demands transparent and conservative assumptions. If your baseline is unrealistic, you'll be accused of greenwashing before you know it.

A few other major challenges pop up, too:

• Defining System Boundaries: Figuring out how far down the chain to measure the impact is tricky. You have to make sure you're drawing the same box around your product and the baseline product to get a fair comparison.
• Avoiding Double-Counting: This is a big one. If several different products all play a part in the same emissions reduction, you could have multiple companies all trying to claim the same benefit. Your methodology has to be smart enough to prevent that.
• Ensuring Transparency: Since there isn't a single, universally mandated standard, the only way to build trust is to document everything—your methods, your data sources, your assumptions. A rigorous, open-book approach is the bedrock of any trustworthy Scope 4 claim.

Getting through these challenges takes a methodical mindset, a commitment to being conservative with your numbers, and a laser focus on transparency.
