The use of biofuels has been considered as a carbon neutral activity. It is based to the assumption that after harvest grows new forest that sequester the carbon that was released earlier. In that case the new forest should grow very fast. The time frame between release and sequestration is however many decades. Also using forest biomass in energy production decreases forest carbon stock. There are numerous researches done of this subject that are natural science that haven’t taken in account the economic side. My aim is to examine and compare the studies with and without the economic point of view. The method is literature survey and comparison of practices in economics and natural science to study carbon neutrality in the use of forest resources. The literature of this subject are multidisclipinary and I have tried to separate economic studies from others according to most relevant analyses and theoretical framework. In the studies there were wide consenus that use of forest resources can’t be considered as a carbon neutral activity. Also there were solid consensus that carbon sequestration increases as forests grow, thus longer rotation period increases carbon sequestration. The studies of natural science was focused among other things for payback times and climate warming. In economics the studies focused for example political management instruments like tax and subsidies. It’s necessary to include economics to the studies because they give more realistic results and guidelines to politics. Without economic aspect it’s hard to make plausible statements to political decisions. The studies of natural science are yet beneficial although they wont alone help for making political decisions. Both economic and natural scientific studies can use information over the branch of science. That’s why it is important to adapt analysis and information to support studies in own branch of science.
