Estimates
The work on the estimate of an SNI started in the mid-1960s. The first rough estimate of an ‘SNI’ for the world by Jan Tinbergen and Roefie Hueting in 1991 arrived at 50 percent of the world production level: the sustainable world income. A much more advanced estimate for The Netherlands was made in 2001 by a collaboration of the National Institute for Public Health and Environment (RIVM), Statistics Netherlands (CBS) and the Institute for Environmental Studies (IVM). The estimate arrived at around 50 percent of the production level, c.q. the national income of The Netherlands. This corresponds with the production level of the beginning of the 1970s. As the population was smaller at that time, the consumption per person was substantially higher than 50 percent of the present level. In accordance with the principles of the SNI it is assumed that all countries in the world simultaneously switch over to environmental sustainability and that the costs thereof are comparable with those of The Netherlands. In the period 1990-2000 the distance between de NI and SNI increased with approximately 10 billion euros.

Famous quotes containing the word estimates:
“A State, in idea, is the opposite of a Church. A State regards classes, and not individuals; and it estimates classes, not by internal merit, but external accidents, as property, birth, etc. But a church does the reverse of this, and disregards all external accidents, and looks at men as individual persons, allowing no gradations of ranks, but such as greater or less wisdom, learning, and holiness ought to confer. A Church is, therefore, in idea, the only pure democracy.”
—Samuel Taylor Coleridge (1772–1834)
“Writing a book I have found to be like building a house. A man forms a plan, and collects materials. He thinks he has enough to raise a large and stately edifice; but after he has arranged, compacted and polished, his work turns out to be a very small performance. The authour however like the builder, knows how much labour his work has cost him; and therefore estimates it at a higher rate than other people think it deserves,”
—James Boswell (1740–1795)
“And, by the way, who estimates the value of the crop which nature yields in the still wilder fields unimproved by man? The crop of English hay is carefully weighed, the moisture calculated, the silicates and the potash; but in all dells and pond-holes in the woods and pastures and swamps grows a rich and various crop only unreaped by man.”
—Henry David Thoreau (1817–1862)
