Hello Sven,
when natural lime is burned ( in medieval times a lot of forest was used
for this process) it looses its carbon.
Once mixed with water and applied to the wall as a render or used
between bricks as mortar ( thus drying), the processed or burned lime 
gets its carbon back from the atmosphere. This is called carbonisation.
