World-System (1960-2100) Steady State and Collapse

 




Several studies indicate that no country has achieved a true steady-state economy, which is defined as an economy with a stable level of resource use maintained within ecological limits. 
However, some countries demonstrate features that could be considered closer to a steady-state approach:
  • Stable resource use: A few countries have shown relatively constant resource use year-to-year, including Denmark, France, Japan, Poland, Romania, and the US.
  • Biophysical degrowth: Germany, Guyana, Moldova, and Zimbabwe are experiencing a decrease in resource use in the majority of indicators.
  • Balancing stability and degrowth: Some countries like Lithuania, Slovakia, Sweden, Ukraine, and the UK demonstrate characteristics that lie between degrowth and stable resource use.
  • Holistic stability: Japan stands out as the only country achieving relative stability across all seven indicators of the Biophysical Stability Index. 
While no country fully embodies a steady-state economy, some countries are showcasing promising trends in resource use and stability that could potentially lead towards a more sustainable economic model in the future.
