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 it was moving toward its goal of becoming carbon neutral by 2030. The Scope 1 measurement was one piece of that picture. By tracking what it directly controlled, Apple could identify where to cut emissions fastest and prove progress year to year.

Understanding what Scope 1 covers helps you read any corporate emissions report. It shows you the difference between a company's own operations and the much larger footprint created by its supply chain and products in use — which fall into Scope 2 and Scope 3.

Key Takeaways

  • Scope 1 emissions come only from sources a company owns or operates directly, such as company vehicles and on-site fuel use.
  • Apple's 2020 Scope 1 emissions were measured in metric tons of CO2 equivalent (tCO2e), a standard unit that lets you compare different greenhouse gases on the same scale.
  • Scope 1 is usually the smallest of the three emission scopes for large tech companies, because most emissions come from supply chains and product use rather than company facilities.
  • Apple reported its Scope 1 figure alongside Scope 2 and Scope 3 to show the full picture of where its carbon footprint came from.

How Apple counted Scope 1 emissions in 2020

Apple measured direct emissions from company-owned or leased facilities, corporate vehicles, and equipment. This included natural gas burned in buildings, fuel used by company cars and trucks, and refrigerants released from air conditioning and refrigeration systems.

The company converted all these different gases into a single number using CO2 equivalent (tCO2e). This conversion accounts for the fact that some gases trap far more heat than carbon dioxide. Methane, for example, is roughly 28 times more potent over a 100-year period, so one ton of methane counts as 28 tCO2e. This standard lets you add up different gases and compare them fairly.

Apple worked with third-party verifiers to check its measurements. The company also followed the Greenhouse Gas Protocol, an international standard that defines which emissions belong in each scope. This consistency matters because it means you can compare Apple's numbers to other companies' reports and know you are looking at the same thing.

Why Scope 1 is small compared to Scope 2 and Scope 3

For a technology company like Apple, Scope 1 emissions are typically the smallest piece of the total carbon footprint. Apple's direct operations — the buildings where employees work and the vehicles they drive — produce far less carbon than the manufacturing of iPhones, MacBooks, and other products, or the electricity those products use over their lifetime.

Scope 2 covers electricity purchased from the grid to power Apple's facilities. Scope 3, the largest category, includes emissions from manufacturing partners, shipping, and customer use of products. A single iPhone manufactured in a coal-heavy region and used for years can generate more emissions than Apple's entire corporate office footprint.

This is why companies serious about carbon reduction often focus first on Scope 3. Scope 1 reductions — switching to electric company vehicles or installing solar panels — are important for credibility and culture, but they move the needle less than redesigning supply chains or making products more efficient.

What the 2020 report included and what it did not

Apple's 2020 Environmental Progress Report stated its Scope 1 emissions figure and explained the main sources. The report also showed how Scope 1 fit into the company's overall carbon footprint and its progress toward the 2030 carbon neutral goal.

The report did not include detailed breakdowns of every facility or vehicle. It did not explain year-by-year changes in Scope 1 alone, because that number fluctuates based on factors like how many employees were in offices (which was reduced in 2020 due to the pandemic) and weather patterns affecting heating and cooling needs.

If you want more granular data — emissions from a specific facility or a comparison to 2019 — you would need to contact Apple directly or look for supplementary technical documents the company may have published alongside the main report.

How to read the tCO2e number in context

When you see Apple's Scope 1 figure in tCO2e, remember that this number alone does not tell you whether the company is doing well or poorly. You need context: Is it lower than the previous year? Lower than competitors? Is the company on track to meet its stated reduction goal?

Apple's 2030 carbon neutral commitment means the company plans to reduce emissions by 75 percent from 2015 levels and offset the remaining 25 percent. The 2020 Scope 1 figure was one data point in tracking that progress. A meaningful assessment requires looking at all three scopes together and checking whether the company's actions — renewable energy investments, supply chain changes, product redesigns — match its numbers.

The tCO2e unit itself is useful because it lets you compare Apple to other companies or to national and global emissions benchmarks. One metric ton of CO2 equivalent is the same whether it comes from Apple, Microsoft, or a manufacturing facility in another country.

Why companies separate emissions into three scopes

The three-scope framework exists because a company's carbon footprint comes from very different sources, and each requires different strategies to reduce. Scope 1 is what the company controls directly. Scope 2 is energy purchased from outside. Scope 3 is everything else — suppliers, transportation, customer use, waste.

This separation helps investors, regulators, and the public understand where emissions actually come from. It also prevents double-counting: if Apple buys electricity from a wind farm, the emissions from generating that electricity appear in Scope 2 for Apple but not in Scope 1, even though the wind farm itself has Scope 1 emissions.

For a company like Apple, this framework reveals that cutting Scope 1 alone would not achieve meaningful climate progress. The company has to transform its supply chain and product design — much harder and more expensive than switching to electric vehicles or renewable energy at headquarters.

How Apple's Scope 1 measurement connects to your own carbon footprint

Understanding Scope 1 helps you think about your own emissions in the same way. Your direct emissions — driving a gas car, heating your home with natural gas, using propane for a grill — are like Scope 1. Your indirect emissions — electricity from the grid, emissions embedded in products you buy, flights you take — are like Scope 2 and Scope 3.

When you read that Apple reduced emissions, you are seeing the result of thousands of decisions: which suppliers to work with, how to power factories, what materials to use in products. Your own carbon footprint works the same way. Reducing it means looking at all three categories, not just the most obvious one.

Frequently Asked Questions

Why does Apple report Scope 1 if it is such a small part of total emissions?

Scope 1 shows what a company controls directly and can change quickly. It also signals commitment: if Apple is serious about climate, it should reduce emissions in its own operations first. Reporting all three scopes together gives a complete picture and shows investors and customers that the company understands where the real work is.

What is the difference between tCO2e and regular tons of CO2?

tCO2e (metric tons of CO2 equivalent) converts different greenhouse gases into a single unit using their warming potential. One ton of methane becomes 28 tCO2e because methane traps heat much more effectively than CO2. This lets you add up different gases and compare them fairly across companies and countries.

Did Apple's Scope 1 emissions go down in 2020?

The 2020 report showed Apple's progress toward its 2030 goal, but the pandemic complicated year-to-year comparisons because fewer employees were in offices. To see whether Scope 1 specifically went down, you would need to compare the 2020 figure to 2019 data in Apple's previous reports or contact the company for detailed historical data.

How does Apple's Scope 1 compare to other tech companies?

Direct comparisons are difficult because companies report with different levels of detail and may define facility boundaries differently. However, Scope 1 is typically the smallest category for all large tech companies. The real differences show up in Scope 3, where supply chain choices and product design create vastly different carbon footprints.

Can I use Apple's Scope 1 number to calculate my share of the company's emissions?

Not directly. Scope 1 covers company operations, not products sold. If you own an Apple device, your share of emissions comes from manufacturing (Scope 3 for Apple) and electricity use, not from Apple's office buildings or vehicles. You would need Scope 3 data to estimate the carbon footprint of the products you use.
