Commodity market
Most types of environmental economics consider the shift to measuring them inevitable, arguing that reframing political economy to consider the flow of these basic commodities first and foremost, helps avoids use of any military fiat except to protect "natural capital" itself, and basing credit-worthiness more strictly on commitment to preserving biodiversity aligns the long-term interests of ecoregions, societies, and individuals.  They seek relatively conservative sustainable development schemes that would be amenable to measuring well-being over long periods of time, typically "seven generations", in line with Native American thought.
