A 60% carbon cut just changed hands

Corporate climate figures are usually discussed as though they belong to the company. They belong to a person, and on 1 September 2026 Apple's changed owner.

The size of Apple's cut

Apple states that its carbon footprint is 60% below 2015 levels. That reduction was achieved over the fifteen years Tim Cook was chief executive, a period in which the company also went from $108 billion of revenue in FY2011 to $416 billion in FY2025 and added more than 100,000 employees.

Cutting absolute emissions by 60% while quadrupling revenue is the difficult version of the exercise. The easy version — the one most published figures describe — is intensity: emissions per unit of something that is itself growing.

Who now owns it

John Ternus, chief executive since 1 September, joined Apple in 2001 and spent his career in hardware engineering, latterly as the senior vice president responsible for it. He was not adjacent to the footprint. Materials, manufacturing and packaging are hardware decisions, and hardware is what he ran.

That is an unusual and rather demanding inheritance. A chief executive who arrives from finance or from software can treat the environmental programme as something reported to them. This one signed off the products it measures.

Where the difficulty sits

There are more than 2.5 billion active Apple devices in use across 200-plus countries and territories. Every one of them was manufactured, shipped and will eventually be disposed of, and the great majority of a device maker's footprint sits in exactly those three places rather than in its offices.

So the number that changed hands is not an office number. It is a supply chain number, and supply chains are slow: a decision taken about a material this year shows up in a footprint several years later, under whoever is running the company by then.

What to watch, and when

Not the announcement. The next annual environmental report is the first document in which a 60% figure is either extended or quietly restated, and it will be the first one this chief executive is answerable for. Fifteen years of reductions is a long enough run that continuing it is unremarkable and breaking it is very visible — which is, in practice, the strongest incentive a climate target ever has.
