Bioenergy can reduce greenhouse gas emissions because the carbon released can be recaptured during plant growth. But it may take decades for emissions from bioenergy to be absorbed, and converting carbon-rich ecosystems to bioenergy production could outweigh any climate benefits.
Bioenergy can be produced from a variety of feedstocks:
* Wood: logs and stumps from plantations or forests
* Oil and fats: crops (rapeseed, sunflower, palm oil, soy, jatropha, etc.), waste oils, animal fats
* Sugar and starch crops: sugarcane, sugar beet, corn, etc.
* Residues: harvesting and processing residues from agriculture (stalks, husks, etc.) and forestry (crowns, bark, sawdust, etc.)
* Waste: manure, municipal solid waste
