...calculation that's been attracting attention is the Happy Planet Index (HPI), which combines economic metrics with indicators of well-being, including subjective measures of life satisfaction, which have become quite sophisticated (HPI uses data from Gallup, World Values Survey, and Ecological Footprint). The HPI assesses social and economic well-being in the context of resources used, looking at the degree of human happiness generated per quantity of environment consumed. The HPI metric was driven in part by the recognition that the environmental costs of economic growth must be figured into standard-of-living reports. (See the worst business deals...

"It's unsustainable, because you're just taking without putting anything back. But when you rotate cattle on grass, you change the equation...
...colleagues used came from the Envisat satellite, launched by the European Space Agency, which gave them a rough picture of methane concentrations across the entire atmosphere. They then combined that with measurements from the multinational Gravity Recovery and Climate Experiment (GRACE) satellite, which gave them a broad estimate of planet-wide groundwater levels. Finally they added surface-temperature data from the U.S. National Center for Environmental Prediction/National CENTER for Atmospheric Research, because heat can increase methane emissions from wetlands as well.
