  • New analysis, based on Google Earth data, indicates that there is 0.9 billion hectares of land available around the world to plant new forests.
  • So far, humans have put 300 gigatonnes of carbon into the atmosphere.
  • Researchers estimate that planting 0.9 billion hectares of forests would absorb two thirds of it.
  • This could be evidence to justify investments in restoring and planting forests.
  • According to the estimate, Earth could support 4.4 billion hectares of forest - excluding existing forests and land in use leaves 0.9 billion for new trees.
