Vegetable Oil and Global Warming Posted on Apr 17 2007 at 9:24pm by It was mentioned several times during a film that describes the use of vegetable oil as a fuel that burning vegetable oil "does not contribute to global warming". This is not the case. The combustion of any oil, including vegetable oil, produces carbon dioxide and water.

RE: Vegetable Oil and Global Warming Posted on Apr 21 2007 at 4:31pm by Certainly any hydrocarbon that is burned with oxygen releases CO2 and H2O.
However, such a fuel cycle can be made carbon-neutral (or carbon-negative) by selecting source plant materials that absorb more atmospheric CO2 during their growth cycle than their derivatives release during combustion. The excess CO2 absorbed from the atmosphere is left behind in the form of un-harvested roots and other plant parts. Part of every plant on earth used to be atmospheric CO2.RE: Vegetable Oil and Global Warming Posted on Jun 20 2007 at 8:27pm by What I've read is that when the plants decompose the carbon dioxide is released into the atmosphere again. If that is true, then it seems to me that planting a tree only temporarily removes carbon dioxide from the atmosphere. That would mean that there is no way to permanently extract carbon dioxide from the atmosphere. The only thing we could do is use less petroleum and that way stop releasing the carbon dioxide that has been stored underground. Or have I missed something in this connection?
