What are peatlands?
• Peat: organic matter accumulated over thousands of
years, storing concentrated carbon in thick layers
Fens occur at groundwater level
Peat bogs accumulate peat above ground water levels
The peat bog is
rain water fed
Tropical peat swamp

Peat, carbon and climate change
• Globally peatlands store 550 Giga ton (Gt) Carbon
• Equivalent to 30% of terrestrial carbon
– twice the carbon stored in forests
– 75% of all carbon in the atmosphere
• Global emissions 2 - 3 Gt CO2 / yr
~ half of LULUCF
Peatlands store large amounts of carbon
Peatland degradation leads to CO2 emissions
which contribute to global warming
Hotspots of CO2 emissions from drained peat
0.5% of land surface
~ 10% global emissions
~ almost half from Annex 1 countries
SE Asia:
~ 6 % of global emissions
• world’s main source area of
peat emissions

Peatland deforestation:
• since 2000: 1.5%/yr: twice the rate for non-peatlands
• currently 45% deforested
Peat forest conservation
• < 5% of total peatland area
Preliminary results

Logging and drainage
• Channels used to
transport equipment
and logs
• Result in drainage
and oxidation of the
peat soil,
• Cause high
emissions of CO2
• Increased fire risks

• Between 1997 and 2006 there were over 60,000 fires in peat
swamp areas on Borneo in 3 out of 10 years (1997, 1998, 2002)
• Most affected were deforested and drained peatlands

Conversion SE Asian peat forest areas
Even when the rate of peatland conversion
decreases, annual peatland emissions will
continue to increase
This makes it a totally different ball game
from forests
Stopping the rate of conversion is not
enough. To decrease peatland emissions
eco-hydrological restoration (rewetting &
replanting) is necessary
Omissions in reporting on peat emissions
• Weak in both Annex 1 and non
Annex 1
• Peatlands unknown
• Drainage often not accurately
assessed
• IPCC default values underestimate emissions
• Emissions from extraction for
horticulture may remain
unreported
Omissions in reporting
• Agricultural fires assumed to
burn renewable biomass
• Ground water extraction and
offsite drainage not recognised
• Estonia, France, Germany,
Latvia, Poland and Romania
are not reporting emissions
from organic soils in general
• Bogs are placed under different
categories
• Unmanaged drained peatlands
ignored
Pros and contras for accounting of peat based
emissions and emission reductions under LULUCF
• No accounting? No incentive! 
• Mandatory accounting
– offsetting against fossil fuel 
– support for higher targets 
– creates incentives for reducing emissions from
peatland degradation 
As a result
• As a result, UNFCCC and Kyoto are overlooking a
large part of the 2000 – 3000 Mt CO2 emissions from
peat degradation
What if current lack of mechanisms is perpetuated?
Use of peat-based palm oil
as biofuel results in 3 to 10
times more emissions as
use of fossil fuels
REDD Recommendations
• Support developing countries
to reduce emissions
• Community-based
approaches
• Deforested peatlands
included
• Exclude drained plantations
• Exclude emission reductions
resulting from peatland
shrinkage
Needed
•Pro-poor development
•Community based mechanisms
•Address root causes of peatland
degradation
– illegal logging
– unsustainable development, e.g.
conversion to plantations
– perverse incentives
•Good governance/Green policy
•Financial incentives
– monetise international peatlands values
