Amazon Rainforest Becomes Net Carbon Source in 2023

A 2026 study published in AGU Advances reveals that the Amazon rainforest emitted more carbon than it absorbed in 2023. The forest released between 10 and 170 billion kilograms of carbon, marking a historic shift in its role as a global carbon sink. This transition occurred despite no increase in forest fires, suggesting a loss of resilience following extreme droughts. The findings indicate that the forest's internal capacity to capture carbon is failing, turning intact green areas into active emission sources.

This is a huge deal for nature based offsets. If the largest sink on earth is flipping to a source, the baseline for carbon credits in the region needs a total rethink.

Agreed. Most current accounting assumes these forests stay stable. If the resilience is gone, we are looking at massive permanence risks for any credits issued there.

The range of 10 to 170 billion kilograms is incredibly wide. It would be useful to know what specific data points caused that much variance in the study.

That variance usually comes from different satellite models versus ground measurements. Still, the fact that the low end is positive emissions is the real story.
