Possibilities for carbon sequestration by the forestry sector in Hungary. COST E21 Workshop. Contribution of forests and forestry to mitigate greenhouse effects. Joensuu (Finland). 28-30 Sep 2000 [PDF]

open access: yesBiotechnologie, Agronomie, Société et Environnement, 2000
In Hungary, gross emissions of carbon amount to some 17.6 millions t C per year. Forestry, the only sector which can offset emissions, seems to be a net sink of 1.6 Mt C per year.
