International agreements and national policy aiming at emission reduct
ion require information on the current situation as wed as recommendat
ions on how to avoid harmful environmental effects in a cast-effective
way, Energy-environment models, such as the LP-model EFOM-ENV, can be
used (1) to analyze the influences of structural changes and energy s
aving measures (2) to study the effects of strategies aiming at a simu
ltaneous reduction of multiple pollutants and (3) to develop emission
and deposition reduction strategies, Selected results of EFOM-ENV appl
ications in several Central and Eastern European countries are present
ed here, They show a high potential for fuel and technology switching
as well as for energy saving measures in these countries. This leads t
o emission reduction costs which are significantly lower than in Weste
rn European countries, (C) 1997 Elsevier Science Ltd, All rights reser
