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 in 2020, this meant measuring carbon dioxide and other gases released by company-owned vehicles, facilities, and equipment — not emissions from suppliers or customers using products.

Apple published its 2020 Environmental Progress Report to show how much direct carbon it was responsible for and what steps it was taking to reduce that number. The report broke down Scope 1 separately from Scope 2 (purchased electricity) and Scope 3 (everything else in the supply chain) because each category requires different solutions. A company cannot reduce emissions from a coal power plant it buys electricity from the same way it reduces emissions from its own delivery fleet.

Understanding what falls into Scope 1 matters because it shows where a company has the most direct control. Apple's Scope 1 number was smaller than its Scope 2 or Scope 3 totals, but it was the category where Apple could make changes without negotiating with outside partners.

Key Takeaways

  • Scope 1 emissions are greenhouse gases Apple produced directly from equipment and facilities it owned, measured in metric tons of carbon dioxide equivalent (tCO2e).
  • Apple's 2020 report separated Scope 1 from Scope 2 and Scope 3 because each requires different reduction strategies and shows different levels of company control.
  • The largest sources of Apple's Scope 1 emissions were company-owned vehicles and natural gas used in buildings, not manufacturing.
  • Apple's Scope 1 emissions were a smaller portion of its total carbon footprint than emissions from suppliers and product use, which fall into Scope 3.

Where Apple's direct emissions came from in 2020

Apple's Scope 1 emissions in 2020 came from two main sources: company vehicles and natural gas burned in buildings. The company operated a fleet of vehicles for employee transport, product delivery, and facility operations. Natural gas heated and powered some of Apple's offices, data centers, and retail locations, though Apple had already shifted many facilities to renewable energy sources.

The report did not break out exact percentages for each source, but natural gas typically accounts for the larger share of Scope 1 emissions at most large companies. Apple's vehicle fleet was smaller relative to its total operations because the company relied on contractors and third-party logistics for most product shipping — those emissions fall into Scope 3, not Scope 1.

Apple also measured fugitive emissions from refrigeration and air conditioning systems, which release refrigerants that trap heat in the atmosphere. These were a smaller component but still tracked as part of the company's direct responsibility.

How Apple measured and reported the 2020 number

Apple used the Greenhouse Gas Protocol Corporate Standard, the most widely accepted framework for measuring business emissions. This standard defines which emissions count as Scope 1, Scope 2, and Scope 3, and it ensures that different companies measure in comparable ways. Apple hired third-party auditors to verify the measurements, which is standard practice for large environmental reports.

The company measured fuel consumption from vehicles and natural gas usage from meters at its facilities, then converted those volumes into metric tons of carbon dioxide equivalent (tCO2e). The conversion accounts for the fact that some gases trap more heat than others — methane, for example, has a higher warming potential than carbon dioxide, so a ton of methane counts as more than a ton of CO2 equivalent.

Apple reported the 2020 Scope 1 figure alongside previous years' data to show whether the number was rising or falling. This year-over-year comparison is more useful than a single-year number because it shows whether a company's reduction efforts are working.

Why Scope 1 is smaller than Scope 2 and Scope 3 at Apple

Apple's Scope 1 emissions were significantly smaller than its Scope 2 (purchased electricity) and Scope 3 (supply chain and product use) totals. This is typical for technology companies because they do not operate factories or power plants directly. Most of Apple's carbon footprint came from suppliers manufacturing components and from customers using devices that required electricity.

Scope 3 emissions — particularly from product manufacturing and use — represented the largest share of Apple's total carbon footprint. A single iPhone uses electricity over its lifetime, and that electricity often comes from power plants that burn fossil fuels. Scope 3 also includes emissions from transporting products to stores and customers, even though Apple does not own all the trucks and ships involved.

Because Scope 1 was the smallest category, it was also the easiest for Apple to reduce. The company could switch company vehicles to electric models or install solar panels on its own buildings without waiting for suppliers to change. However, the biggest carbon reductions required working with suppliers and designing products that used less energy — changes that took longer and involved more partners.

What Apple's 2020 Scope 1 report included and excluded

Apple's report included all direct emissions from facilities and vehicles the company owned or operated. This covered Apple's offices, retail stores, data centers, and company-owned vehicles. The report also included emissions from business travel on company-owned aircraft, though Apple's private aviation use was limited compared to other large corporations.

The report excluded emissions from leased vehicles and facilities where Apple did not have operational control. If Apple leased office space in a building where the landlord controlled the heating system, those emissions counted as Scope 2 (purchased energy) or were attributed to the landlord, not to Apple. This boundary matters because it affects how much responsibility Apple claims for its carbon footprint.

The report also did not include emissions from contractors and suppliers, even when Apple paid them to perform work. Those emissions fall into Scope 3 and are tracked separately. This distinction is important because it shows what Apple directly controlled versus what it influenced through purchasing decisions.

How Apple's Scope 1 reduction strategy worked

Apple's approach to reducing Scope 1 emissions focused on two areas: converting vehicles to electric power and installing renewable energy at facilities. The company expanded its electric vehicle fleet and worked with charging infrastructure providers to support employee adoption of EVs. For buildings, Apple installed solar panels and geothermal systems at multiple locations and purchased renewable energy credits to offset natural gas use.

The company also improved building efficiency by upgrading insulation, HVAC systems, and lighting. These changes reduced the amount of natural gas and electricity needed to heat and cool spaces. Apple set a target to reach carbon neutrality across its direct operations by 2030, which meant Scope 1 and Scope 2 emissions would need to approach zero.

However, the 2020 report acknowledged that some Scope 1 emissions would be harder to eliminate. Certain facilities and vehicles did not yet have viable zero-carbon alternatives, and switching them would require technology that was still in development or too expensive at scale. Apple's strategy included investing in emerging technologies like sustainable aviation fuel and advanced battery systems.

How Scope 1 fits into Apple's total carbon footprint

Scope 1 was one piece of Apple's total greenhouse gas footprint, but not the largest piece. The company reported all three scopes together to show the full picture. Scope 3 — which included manufacturing, transportation, and product use — represented roughly 75 percent of Apple's total emissions. Scope 2 (purchased electricity) was the second-largest category. Scope 1 was the smallest but still significant enough to measure and reduce.

Understanding this breakdown matters because it shows where Apple's biggest climate impact came from and where the company needed to focus its efforts. Reducing Scope 1 emissions was important for demonstrating commitment and for the areas where Apple had direct control, but the real carbon reductions would come from working with suppliers to make manufacturing cleaner and designing products that used less energy over their lifetime.

Apple's 2020 report presented Scope 1 as part of a broader strategy that addressed all three categories. The company could not reach carbon neutrality by only reducing direct emissions — it needed suppliers to decarbonize their operations and customers to use products more efficiently.

Frequently Asked Questions

Why does Apple separate Scope 1 from Scope 2 and Scope 3?

Each scope requires different solutions. Scope 1 is under Apple's direct control, so the company can switch to electric vehicles or install solar panels without negotiating with partners. Scope 2 and Scope 3 require working with electricity providers and suppliers, which takes longer and involves more stakeholders.

What is tCO2e and why does Apple use it instead of just measuring carbon?

tCO2e stands for metric tons of carbon dioxide equivalent. It converts different greenhouse gases into a single number by accounting for how much heat each gas traps. Methane and refrigerants trap more heat than carbon dioxide, so the same weight of these gases counts as more tCO2e.

Did Apple's Scope 1 emissions go down between 2019 and 2020?

The 2020 report showed year-over-year changes, but the specific numbers and direction of change depend on which facilities and vehicles Apple included in each year's measurement. The report indicated progress toward the 2030 carbon neutrality target, though Scope 1 was not the main driver of that progress.

Can Apple eliminate Scope 1 emissions completely by 2030?

Apple's target is carbon neutrality, not zero emissions. This means the company will reduce emissions as much as possible and offset remaining emissions through carbon credits or removal projects. Some Scope 1 sources — like certain specialized equipment or facilities in remote locations — may not have zero-carbon alternatives available by 2030.

Why is Scope 1 smaller than Scope 3 for a company like Apple?

Apple does not own factories or power plants, so it does not produce emissions directly at the scale of manufacturing companies. Most of Apple's carbon footprint comes from suppliers making components and from customers using devices that require electricity. These fall into Scope 3, which is why it is the largest category.
