A life cycle assessment by the Yale School of Forestry on jatropha, one source of potential biofuels, estimated using it could reduce greenhouse gas emissions by up to 85% if former agro-pastoral land is used, or increase emissions by up to 60% if natural woodland is converted to use.
Šumarski fakultet u Yaleu o jatrofi ( jednom od potencijalnih biogoriva) procjenjuje se da bi ona mogla smanjiti emisiju stakleničkih plinova do 85% ako se koristi poljoprivredno zemljište ili ako se upotrebljava prirodna šuma moglo bi smanjiti emisiju stakleničkih plinova do 60% .
