• A study has found that rising greenhouse gas emissions could significantly impact the sustainability of Earth’s orbital space.
  • Higher emissions reduce atmospheric density, slowing down the natural decay of space debris.
  • By 2100, under high-emission scenarios, the sustainable number of satellites in orbit could drop by 50-66%.
  • A decrease in the rate of satellite deorbiting increases risks of space debris accumulation.
  • Space sustainability is now being linked directly to climate change mitigation efforts
