Scope 3 Category 11: Use of sold products

Scope 3 Category 11 covers emissions from the use of sold products over their expected lifetime — energy or fuel consumed by products in customers’ hands. It is often material for vehicles, appliances and fuels, and usually needs lifetime assumptions plus typical use-phase activity per product sold.

Category 11 is the use-phase of sold products — energy or fuel customers consume over the product lifetime.

Combine units sold with lifetime use assumptions (energy per use, lifetime years, load factors). Critical for vehicles, appliances, fuels and energy-consuming equipment.

Indirect use-phase (e.g. washing clothes) needs clear assumptions. Direct use-phase (fuel burned in a sold vehicle) is usually clearer to bound.

Frequently asked questions

How long a lifetime should I assume?
Use product design life, warranty policy or sector norms — and disclose the assumption. Sensitivity analysis helps when lifetime drives the total.
Do services have Category 11?
Often immaterial. Category 11 focuses on sold products that consume energy or emit GHGs in use.
Are fuel sales Category 11?
Yes — combustion of sold fuels by customers is a classic Category 11 case, using volumes sold and appropriate combustion factors.
How does this differ from Category 10?
Category 10 is processing before the end user. Category 11 is use by the end user over the product lifetime.
Should I include electricity for electric products?
Yes when material — estimate lifetime electricity use and apply appropriate grid or location assumptions, disclosed in the method.
