This is a common but incorrect assumption. Biofuels are very far from carbon neutral. Renewable is in no way restricted to the desirable.

- dTal 7y agoSetting aside other issues with it like particulate emission, how can it be anything other than carbon neutral? Where could the surplus carbon possibly come from?
- acidburnNSA 7y agoWhen biofuels are valuable, people clear forests to make biofuel. The carbon payback period can be up to 1000 years. It's called indirect land use change [1,2] [1] https://en.wikipedia.org/wiki/ILUC https://en.wikipedia.org/wiki/ILUC [2] https://en.wikipedia.org/wiki/Biofuel#Greenhouse_gas_emissions https://en.wikipedia.org/wiki/Biofuel#Greenhouse_gas_emissio...
