[en] To date, little is known about the impact of processes
which cause lateral carbon fluxes over continents, and
from continents to oceans on the CO2 – and carbon budgets at
local, regional and continental scales. Lateral carbon fluxes
contribute to regional carbon budgets as follows: Ecosystem
CO2 sink=Ecosystem carbon accumulation+Lateral carbon
fluxes. We estimated the contribution of wood and food
product trade, of emission and oxidation of reduced carbon
species, and of river erosion and transport as lateral carbon
fluxes to the carbon balance of Europe (EU-25). The analysis
is completed by new estimates of the carbon fluxes of coastal
seas. We estimated that lateral transport (all processes combined)
is a flux of 165 Tg C yr−1 at the scale of EU-25. The
magnitude of lateral transport is thus comparable to current
estimates of carbon accumulation in European forests. The
main process contributing to the total lateral flux out of Europe
is the flux of reduced carbon compounds, corresponding
to the sum of non-CO2 gaseous species (CH4, CO, hydrocarbons,
. . . ) emitted by ecosystems and exported out of the
European boundary layer by the large scale atmospheric circulation.
