	Using biofuels in an engine still produces [[carbon dioxide]]. However, since they're derived from recent biomass which took in CO<sub>2</sub> as it was growing, the CO<sub>2</sub> released in [[hydrocarbon combustion\|combustion]] is the "same" as they took in. This makes biofuels far closer to carbon neutral (no net ~~release of~~ carbon ~~dioxide to the atmosphere~~) than fossil fuels.<ref> S. Paulson, Ph.D. (2013). ''Biodiesel Fuel'' [Online]. Avaliable: http://www.environment.ucla.edu/reportcard/article7320.html</ref> Any remaining descrepancies between the input and output CO<sub>2</sub> of biofuels need careful [[life cycle analysis]] to be measured.

	Biofuels and [[fossil fuel]]s ([[coal]], [[oil]] and [[natural gas]]) are both derived from organic matter, but differ in how recently the organic matter died. Fossil fuels come from organic matter that died millions of years ago (see the [[time scale of the universe]] page), whereas biofuels come from recently deceased matter.

Fossil fuels come from organic matter that died millions of years ago (see the [[time scale of the universe]] page), whereas biofuels come from recently deceased organic matter.

	From a climate change perspective, biofuels release just as much carbon dioxide as fossil fuels. However, since the CO<sub>2</sub> from biofuels came from the atmosphere recently it doesn't change the amount of carbon circulating through the [[carbon cycle]]. In this cycle, the carbon exists in the [[atmosphere]], [[ocean]] and biosphere, as opposed to the Earth's solidified carbon supply—where fossil fuels come from.<ref> EMBO Reports. (2008).

			==Interactive graph==
			The graph below shows energy production by energy type for countries around the world. Search for or click on different countries to see how much biomass they produce as a fraction of their total energy production. To see countries that use a great deal of biomass, look for less developed countries.
