Growth embedded in a finite Earth

This paper puts forth a growth model that takes into account the fact that the economy is embedded in a finite Earth. Economic activity causes greenhouse gas (GHG) emissions into the atmosphere and uses services from the biosphere. There are two main messages from the analysis: First, R&D in technologies that reduce GHG emissions and inputs from the biosphere must be ramped up rapidly. Second, in view of the fact that the top 10% of the world's inhabitants have roughly 76% of the world's wealth, consumption that causes emissions and uses inputs from the biosphere must decrease rapidly.
