How Forests Are Losing Their Carbon Absorption Capacity

Forests are absorbing less carbon than they used to: heat stress, drought, wildfires and degradation are weakening the world's largest natural carbon sink precisely when we need it most. Parts of some forests now emit more carbon than they capture — making restoration and protection urgent climate priorities.

Why absorption is declining

  • Heat and drought stress. Stressed trees grow slower and absorb less CO₂; many die.
  • Wildfires. Burning releases decades of stored carbon in days.
  • Degradation. Logged and fragmented forests store far less than intact ones.
  • Saturation effects. Older forests absorb more slowly; without new growth, net uptake falls.

What this means for climate strategy

We can no longer treat forests as an infinite free sink. Emission cuts matter more, and so does actively rebuilding absorption capacity: young, healthy, diverse forests are vigorous carbon absorbers for decades. Where trees are planted — species, climate, survival — determines how much carbon is truly captured, which is why monitoring matters.

Rebuild the sink, verifiably

Evertreen plants geolocated, satellite-monitored trees in verified projects and publishes its methodology openly — see how we estimate tree CO₂. Plant trees that restore absorption capacity, with conservative per-species estimates.

Frequently asked questions

Are forests still carbon sinks? Globally yes, but a weakening one — climate stress, fires and degradation are reducing net absorption, with some regions becoming sources.

Why do young forests matter? Growing trees absorb CO₂ vigorously for decades; restoring degraded land adds new absorption capacity.

How is real absorption verified? Through species-specific estimates, geolocation and monitoring — Evertreen publishes its methodology and tracks every tree.
