ONCLUSION
Alarming global climate changes and limited reserves of fossil fuels expanded the market
with biofuels. Despite the rapid marked expand there are still some questions to be answered
before fully substituting the fossil fuels with liquid biofuels. One of these questions is
environmental sustainability of biofuels.
feedstock
yield
for
biofuels
production
are
strongly
influenced
by
local
meteorological conditions like temperature and precipitation;
environmental impacts are distinguished, due to location of feedstock production;
assessment of liquid biofuels should include the whole LCA, from feedstock
production to the biofuel production and consumption. Only when all inventories and
energy flows are taken in to the account real environmental, health and social
assessment of acceptability can be done;
since the environmental impacts are related to yield of feed stocks, it is questionable
whether the countries would assure enough quantities of biofuels to meet the policy
goals. The challenge is being addressed also to reach increasing demand to biofuels
and at the same time decrease environmental impacts;
Nowadays the question is not whether renewable biofuels will play a significant role in
providing energy for transportation, but rather what the implications of their use will be for
economy, for the environment, for global security and for the health of whole mankind.
