What Scope 1 emissions are and why Apple measured them

Scope 1 emissions are the greenhouse gases a company produces directly from sources it owns or controls. For Apple, this meant measuring carbon dioxide and other gases released by the company's own vehicles, manufacturing equipment, and facilities during 2020. Apple reported 75,471 metric tonnes of CO2 equivalent (tCO2e) in Scope 1 emissions that year—a number that matters because it shows what a large corporation can actually measure and reduce when it commits to tracking.

Apple published this data in its Environmental Progress Report because investors, regulators, and customers increasingly expect companies to report their climate impact honestly. The report was not required by law in 2020, but Apple chose to measure and publish it anyway. This transparency lets you see how one of the world's largest companies approaches emissions reduction, and what kinds of sources actually make up a corporation's direct carbon footprint.

Understanding Scope 1 matters to vehicle owners because it shows the difference between what a company controls directly (its own fleet, its own buildings) and what it influences indirectly (how suppliers operate, how customers use products). That distinction shapes what emissions reductions are actually possible and how long they take.

Key Takeaways

  • Scope 1 emissions are greenhouse gases a company produces directly from equipment and vehicles it owns, not from its supply chain or customer use.
  • Apple's 75,471 tCO2e of Scope 1 emissions in 2020 came mainly from company vehicles, manufacturing facilities, and corporate offices.
  • Scope 1 is only one part of a company's total emissions—Scope 2 (purchased electricity) and Scope 3 (supply chain and product use) are often much larger.
  • Companies measure Scope 1 first because these are the emissions they control directly and can reduce fastest through vehicle replacement and facility upgrades.

Where Apple's Scope 1 emissions actually came from

Apple's 75,471 tCO2e of Scope 1 emissions in 2020 came from three main sources: company vehicles, natural gas and fuel burned in buildings, and refrigerants used in air conditioning and cooling systems. The company did not break down the exact percentage from each source in the public report, but vehicles and building heating typically account for the majority of Scope 1 for large corporations.

Company vehicles include the cars Apple employees drive for work, shuttle buses between facilities, and delivery vehicles. Natural gas burned for heating and hot water in Apple's offices, retail stores, and data centers produces CO2 directly. Refrigerants in air conditioning systems release potent greenhouse gases if they leak during maintenance or at the end of equipment life—these are measured separately because they have a much higher warming effect per unit than CO2.

The reason Apple measures these sources is that they are under the company's direct control. If Apple decides to replace a diesel shuttle bus with an electric one, or upgrade a building's heating system, the emissions from that source drop when ready. That is why Scope 1 is often the easiest part of a company's carbon footprint to reduce, even though it is usually the smallest part of the total.

How Scope 1 compares to Scope 2 and Scope 3

Apple's 75,471 tCO2e of Scope 1 emissions is a real number, but it represents only a fraction of the company's total climate impact. Scope 2 includes emissions from electricity Apple purchases to power its offices and data centers—a much larger number. Scope 3, which covers the entire supply chain and how customers use Apple products, is typically the largest of all three.

For context, when companies report their climate impact, Scope 1 is often 5 to 15 percent of the total, Scope 2 is 10 to 30 percent, and Scope 3 is 50 to 85 percent. Apple's exact breakdown varies by year and by how the company defines its boundaries, but the pattern holds: direct emissions from company operations are real but small compared to the emissions baked into manufacturing and product use.

This matters because it shapes what a company can actually control. Apple can switch its vehicle fleet to electric relatively quickly. It can install solar panels and buy renewable electricity. But it cannot when ready change how its suppliers operate or how millions of customers use iPhones. Those changes take longer and require working with other organizations.

Why companies measure Scope 1 first, even though it is the smallest part

Scope 1 is the easiest to measure and the fastest to reduce, which is why Apple and other corporations start there. The company owns the vehicles, owns the buildings, and has direct access to the utility bills and equipment records. There is no guessing about what happened in a supplier's factory or how a customer charged their phone.

Reducing Scope 1 also builds credibility. When Apple replaces a diesel vehicle with an electric one, that reduction is real and verifiable. It shows investors and the public that the company is serious about emissions, not just making promises. Once a company has proven it can cut its own emissions, it has more standing to ask suppliers and customers to do the same.

The downside is that focusing only on Scope 1 can create a false impression of progress. A company could cut its direct emissions by 50 percent while its total climate impact barely budges, because Scope 3 is so much larger. That is why honest climate reporting includes all three scopes, even though Scope 1 gets the most attention.

How Apple's 2020 Scope 1 number connects to its broader climate goals

Apple announced in 2020 that it aimed to reach carbon neutrality across its entire business by 2030. The 75,471 tCO2e of Scope 1 emissions was a baseline—a starting point to measure progress against. By publishing the number, Apple committed to reducing it year over year and reporting the results publicly.

Reaching carbon neutrality by 2030 means Apple will need to cut emissions across all three scopes, not just Scope 1. For Scope 1, that means converting company vehicles to electric, upgrading buildings to renewable heating, and replacing high-emission refrigerants. For Scope 2, it means sourcing 100 percent renewable electricity. For Scope 3, it means working with suppliers to reduce manufacturing emissions and designing products that use less energy when customers use them.

The 2020 report was a snapshot of where Apple stood at one moment. The value of the number is not the number itself, but the fact that it was measured, published, and tied to a specific reduction target. That transparency lets you track whether the company is actually following through.

What this report means for understanding corporate emissions claims

When a company publishes an emissions report, it is usually following a standard framework called the Greenhouse Gas Protocol. This framework defines what counts as Scope 1, Scope 2, and Scope 3, so that different companies measure roughly the same way. Apple's 2020 report followed this framework, which means the number is comparable to emissions reports from other large corporations.

However, companies still have choices about what to include and how to count. Some companies count emissions from leased vehicles as Scope 1; others count them as Scope 3. Some include business travel by plane; others do not. These choices can make a real difference in the final number, which is why reading the methodology section of an emissions report matters as much as reading the headline number.

Apple's report included its methodology, which is a sign of honest reporting. If a company publishes only the number without explaining how it was calculated, that is a red flag. The 2020 report showed that Apple was willing to be transparent about its measurement approach, even though that transparency sometimes reveals limitations in what the company can measure.

Frequently Asked Questions

Why is Scope 1 so much smaller than Scope 3 for most companies?

Scope 1 covers only what a company owns directly—its vehicles and buildings. Scope 3 covers everything else: how suppliers make parts, how products are shipped, and how customers use the product. For a company like Apple that manufactures globally and sells to hundreds of millions of people, Scope 3 is vastly larger because it includes the energy used by all those customers.

Does Apple's Scope 1 number include emissions from its retail stores?

Yes. Apple's retail stores use natural gas for heating and electricity for lighting and air conditioning. The natural gas portion counts as Scope 1. The electricity portion counts as Scope 2. Apple owns or leases these stores, so both scopes are under its direct control.

Can a company reduce its Scope 1 emissions to zero?

Mostly yes, but not completely. A company can switch vehicles to electric, heat buildings with renewable energy, and replace high-emission refrigerants. However, some industrial processes and emergency backup systems still require fossil fuels. Most companies aiming for carbon neutrality plan to offset these remaining emissions through carbon credits rather than eliminate them entirely.

How often does Apple update its Scope 1 emissions number?

Apple publishes an updated Environmental Progress Report annually, usually in the spring. Each report includes updated Scope 1, Scope 2, and Scope 3 numbers for the previous year. This lets you track whether the company is actually reducing emissions or whether the number is staying flat or growing.
