Carbon emission from tropical forests


From UPSC perspective, the following things are important :

Prelims level : Forgone carbon removal

Mains level : Carbon emission from tropical forests

  • A new study says that carbon impacts from the loss of intact tropical forests have been grossly underreported.

About the study

  • The study has calculated new figures relating to intact forest lost between 2000-2013.
  • It has found that the long-term net carbon impacts, through 2050, are six times the current estimates.
  • Conventionally, only carbon emissions from readily observed forest clearance are considered.
  • This study accounted for less readily observed degradation processes that follow forest clearance – selective logging, edge effects, and defaunation.

Forgone carbon removal

  • Another metric used in the new study is “forgone carbon removal”.
  • Forgone removals are an estimate of the amount of carbon that cleared or degraded forests could have sequestered had they remained intact beyond 2000.
  • Full accounting of these additional factors led to a 626% increase in cumulative net carbon impact from intact forest loss, the study says.
