How much greenhouse gases does the rainforest contribute each year?

Rainforests play a crucial role in the global carbon cycle by absorbing approximately 1.1 billion metric tons of carbon dioxide (CO2) annually through photosynthesis. However, when trees die or are cut down, they release stored carbon back into the atmosphere, contributing to greenhouse gas emissions. Overall, while rainforests act as significant carbon sinks, deforestation and degradation can lead to the release of vast amounts of greenhouse gases, estimated at around 1.5 billion metric tons per year globally. Therefore, their net impact on greenhouse gas levels depends on both their conservation and the extent of deforestation.
