  • Various methods are employed for this purpose.
  • For instance, abandoned coal seams can be used to trap CO2, and CO2 can be injected into oil fields to enhance oil recovery.
  • Additionally, forests and wetlands serve as natural carbon sinks, while subterranean deep saline formations can also be used for carbon storage.
  • Therefore, statements 1, 2, and 3 are all correct.
