carbon sink

Atmospheric CO2 reservoir

A carbon sink is a natural or artificial system that absorbs more carbon dioxide from the atmosphere than it releases, effectively storing carbon.

Forests, oceans, and soil are major natural carbon sinks.

The term appears frequently in climate discussions: We need to protect forests as vital carbon sinks.

The opposite—a system releasing more carbon than it absorbs—is a carbon source.
