The carbon maps that Mathieu provided are a good starting point, but if you need to estimate it for different land uses then you will have to either do on the ground measurements, or use soil carbon models (such as CENTURY or RothC) to refine to local estimates.  There are more sophisticated techniques if you have access to hyperspectral imagery to calculate carbon, but that is expensive and processing heavy. Best bet in my opinion is to use the baseline information in the maps and modify that to individual land uses via a soil carbon model. 

Dear Dani,

These publication links could be useful for estimation of carbon in forest land use using remote sensing and GIS.
