Material Input Per Service Unit
Material input per unit of service (MIPS) is an economic concept, originally developed at the Wuppertal Institute, Germany in the 1990s. The MIPS concept can be used to measure eco-efficiency of a product or service and applied in all scales from a single product to complex systems. The calculation takes into account materials required to produce a product or service. The total material input (MI) is divided by the number of service units (S). For example in case of a passenger car, the number of service units is the total number of passenger kilometres during the whole life span of the vehicle. The lower the material input per kilometre, the more eco-efficient is the vehicle. The whole life-cycle of a product or service is measured when MIPS values are calculated. This allows comparisons of resource consumption of different solutions to produce the same service. When a single product is examined, the MIPS calculations reveal the magnitude of resource use along the life-cycle and help to focus efforts on the most significant phases to reduce environmental burden of the product.

Famous quotes containing the words material, input, service and/or unit:
“Since art is the expression of beauty and beauty can be understood only in the form of the material elements of the true idea it contains, art has become almost uniquely feminine. Beauty is woman, and also art is woman.”
—Rémy De Gourmont (1858–1915)
“Family life is not a computer program that runs on its own; it needs continual input from everyone.”
—Neil Kurshan (20th century)
“Let the good service of well-deservers be never rewarded with loss. Let their thanks be such as may encourage more strivers for the like.”
—Elizabeth I (1533–1603)
“During the Suffragette revolt of 1913 I ... [urged] that what was needed was not the vote, but a constitutional amendment enacting that all representative bodies shall consist of women and men in equal numbers, whether elected or nominated or coopted or registered or picked up in the street like a coroner’s jury. In the case of elected bodies the only way of effecting this is by the Coupled Vote. The representative unit must not be a man or a woman but a man and a woman.”
—George Bernard Shaw (1856–1950)
