Material input per unit of service

Material input per unit of service (MIPS) is a unit of eco-efficiency that quantifies the sustainability of production by breaking down products into services they provide and examining the amount of material that needs to be displaced in order to provide a unit of service.As an example: Automobile factories don't make automobiles but services of transportation. A car is broken down into the mileage it provides as services and that is evaluated against total material displacement in manufacturing, fueling, maintenance and waste disposal.
