Material Intensity Factors
The cornerstone of MIPS calculations are the material intensity factors. The Wuppertal Institute has the most extensive list of MI-factors. Factors are provided for a wide range of basic materials and energy. The factors indicate how many kilograms of natural resources in each of the five natural resource categories are used or transferred in the ecosystem to produce one kilogram of certain material or a unit of energy.

Famous quotes containing the words material, intensity and/or factors:
“The material was pure, and his art was pure; how could the result be other than wonderful?”
—Henry David Thoreau (1817–1862)
“Consider the difference between looking and staring. A look is voluntary; it is also mobile, rising and falling in intensity as its foci of interest are taken up and then exhausted. A stare has, essentially, the character of a compulsion; it is steady, unmodulated, “fixed.””
—Susan Sontag (b. 1933)
“The goal of every culture is to decay through over-civilization; the factors of decadence,—luxury, scepticism, weariness and superstition,—are constant. The civilization of one epoch becomes the manure of the next.”
—Cyril Connolly (1903–1974)
