Objectives of ICOS

• To establish an integrated long-term global GHG
  observation infrastructure
• To determine regional GHG fluxes from
  observations and attribute these to processes
• To enable early detection of surprises
• To provide regional GHG budgets for policy
  support
• To provide access and services for data and data

CO2 Emissions from Fossil Fuels
Increase rate 1990 - 1999 1.3 y-1 2000 -
2006 3.3 y-1
Acceleration of the increase of fossil fuel CO2
emissions since 2000
5
Recent trend of Fossil Fuel Emissions
Recent increase of CO2 emissions higher than all
the IPCC's scenarios
6
CO2 accumulation in the atmosphere
Only 46 of the fossil fuel emissions remain in
the atmosphere
7
Fate of Anthropogenic CO2 Emissions (2000-2007)
1.5 Pg C y-1

7.5 Pg C y-1

Climate Change at 55 Discount
Natural CO2 sinks absorb 55 of all anthropogenic
carbon emissions slowing down climate change
significantly. They are in effect a huge subsidy
to the global economy worth 50 billions US
annually if an equivalent sink had to be created
using other climate mitigation options (10 per 1
ton of Carbon)
