This being that most global emissions originate, at root, in the mineral resources of a small number of desert nations, who form a discontinuous rim around the southern and western sides of the Indian Ocean. With the gradual exhaustion of more easily smelted chalcophile mineral resources originating from the younger lands of the remainder of the globe, industry – and most especially high technology – can only become more and more dependent upon these desert Indian Rim countries. Indeed, as oil becomes exhausted and electronic technology more and more important, Australia alone will become more and more exclusively the source of mineral wealth for industry, since the vast majority of important minerals for the electronics sector like sand and lanthanide elements come from Australia, and can only be sourced elsewhere at high cost. Among present-day continents Australia is uniquely un-depleted in these elements, whose extreme affinity for oxygen means they concentrate to an extreme extent in ancient continental cratons. The Australian Craton alone has 20 percent of the Earth’s total budget of lanthanide elements, including the core and mantle.
For various political and geographic reasons, these Indian Rim nations – Australia, New Caledonia, Southern Africa and the Persian Gulf States – have generally the highest per capita greenhouse gas emissions in the world even when indirect emissions are counted elsewhere, with only North America and a few small declining industrial nations comparable:

- soon-to-be-exhausted deposits of more “ancient” (less reactive) chalcophile elements like lead, zinc or copper or
- fossil fuels or lithophile minerals imported from the desert states of the Indian Rim
My brother said that most of Australia‘s greenhouse emissions are the result of China’s industrialisation, but I think he has placed the cart before the horse. The ability to smelt and use abundant lithophile metals with very strong bonds with oxygen and hence enrichment in cratonic crust is the cause of industrialisation in East Asia. Asia industrialised preferentially over Latin America and Africa because of its large and consistently growing comparative disadvantage in agriculture, and Asian greenhouse pollution is small per capita and largely created from Australian, Southern African and Gulf minerals. Australia could develop its own polluting industry without China or India or Europe, but East Asia and Europe without lithophile metallurgy and the “Green Revolution” (which adds further to Australian emissions by permitting even poorer land to be cleared) would lack both adequate raw materials for major manufacturing and the comparative disadvantage in agriculture that encourages industrial development. For this reason, China’s and India’s emissions are much more dependent upon Australia than the other way round.
Although Australia is extremely unfavourably situated for manufacturing, this could well become unimportant if environmental regulations in the Enriched World toughen and those in Australia do not. There must exist a point beyond which lower taxes and fewer regulations would overwhelm Australia’s geographic disadvantages in manufacturing industry, especially since excessive regulation helps create demographic decline which is already well-advanced in Japan and incipient in the rest of the Enriched and Tropical Worlds.
These facts demonstrate a mere 26 percent cut in Australian emissions as both inadequate and difficult to maintain in the long term.
The usefulness of per capita emissions is a little arbitrary because of demographic differences and human migration, so that I have felt the need to look for something more genuinely “ecological” as an indication of the sustainable energy consumption of a country. Since soil nutrients determine the quality and amount of energy animal can consume, I feel greenhouse emissions per unit of available soil nutrients (extremely difficult to measure over large areas) Australia would be permitted extremely limited emissions relative to what it emits today. Australian soils average an order of magnitude less available phosphorus at the surface than Enriched World soils, and this difference increases with depth. Thus, per unit of soil fertility Australia’s emissions are certainly much higher than most major European nations (e.g. France, Spain) and orders of magnitude higher than most less-developed nations. This difference is of course much, much more extreme if we consider either:
- “poor metal” micronutrients (whose importance to Australia’s ecology has been outlined by Gordon Orians and Antoni Milewski in ‘Ecology of Australia: The Effects of Nutrient-Poor Soils and Intense Fires’)
- the large proportion of overseas emissions produced by the use of Australian minerals
