Worldwide, Carbon-Rich Peatlands are Dangerously Under-Protected

New Study | February 2025 | Conservation Letters

600 billion tons of carbon stored - more than all forests combined

By Wildlife Conservation Society

Why Peatlands Matter

3% of Earth's surface
600B tons of carbon stored
17% currently protected

Peatlands store more carbon than all the world's forest biomass combined.

Protection Levels: Peatlands vs Other Ecosystems

Peatlands
17%
Mangroves
42%
Saltmarshes
50%
Tropical Forests
38%

Nearly one-quarter of peatlands face heavy human pressure.

Peatlands Under Pressure

15%
drained for agriculture
5-10%
degraded through vegetation loss or mining
40%+
degraded in tropical regions
1.5-2.5B tons
CO2 emitted annually from damaged peatlands
"Failure to protect peatlands puts their carbon stores at high risk" - Kemen Austin, PhD

Indigenous Peoples: Vital Caretakers

27% of global peatlands on Indigenous lands
1.1M km² under Indigenous stewardship
85% lack other formal protection

Strengthening land rights = stronger conservation outcomes

"Indigenous Peoples are already important caretakers of peatlands" - Paul Elsen, PhD

Where Are the World's Peatlands?

Top 10 countries hold 80% of global peatlands:

  • 🇨🇦 Canada
  • 🇷🇺 Russia
  • 🇮🇩 Indonesia
  • 🇺🇸 USA
  • 🇧🇷 Brazil
  • 🇨🇩 DRC

More Than Carbon: Why Peatlands Matter

Freshwater

10% of world's unfrozen freshwater stored in peatlands

Biodiversity

Home to mosses, birds, fish, butterflies, and snails

Climate

Critical for limiting global warming to 1.5°C

Conservation of undegraded peatlands + recovery of degraded ones is essential.

The Time to Act Is Now

"If we act now to conserve peatlands, then we can reap some enormous benefits - at a relatively low cost." - Kemen Austin, PhD
  • Elevate peatlands in UNFCCC negotiations
  • Support national peatland strategies
  • Strengthen Indigenous land rights
  • Fund conservation and restoration
