Treethanol

Treethanol is Ethanol fuel (more precisely Cellulosic ethanol) made from trees.

Forest trees contain more than 90% of the Earth’s terrestrial biomass, providing such environmental benefits as carbon capture, sustainable energy supplies, improved air quality, and biodiversity. Trees are a particularly promising source of ethanol because they grow all year round, require significantly less fertiliser and water and contain far more carbohydrates (the chemical precursors of ethanol) than food crops (like corn) do.

Criticism
Treethanol cannot help to fight against GHG because destroys trees and forest.

It is preferred biofuels from non-feedstock herbal crops (pure energy crops).
