About 86.1% of diesel fuel mass is carbon, and when burned, it offers a net heating value of 43.1 MJ/kg as opposed to 43.2 MJ/kg for gasoline. Due to the higher density, diesel fuel offers a higher volumetric energy density: the density of EN 590 diesel fuel is defined as {{cvt|0.820|to|0.845|kg/L|lb/USgal}} at {{cvt|15|C}}, about 9.0-13.9% more than EN 228 gasoline (petrol)'s {{cvt|0.720|-|0.775|kg/L|lb/USgal}} at 15&nbsp;°C, which should be put into consideration when comparing volumetric fuel prices. The {{CO2}} emissions from diesel are 73.25 g/MJ, just slightly lower than for gasoline at 73.38 g/MJ.<ref>{{cite web|url=http://ies.jrc.ec.europa.eu/uploads/media/TTW_Report_010307.pdf|title=Table 2.1|url-status=dead|archive-url=https://web.archive.org/web/20110720162258/http://ies.jrc.ec.europa.eu/uploads/media/TTW_Report_010307.pdf|archive-date=2011-07-20}}</ref>

Diesel fuel is generally simpler to refine from petroleum than gasoline. Additional refining is required to remove sulfur, which contributes to a sometimes higher cost. In many parts of the United States and throughout the United Kingdom and Australia,<ref>{{cite web|url=http://www.aip.com.au/pricing/facts/Facts_about_Diesel_Prices.htm|title=Facts about Diesel Prices|access-date=2008-07-17|archive-url=https://web.archive.org/web/20080719113021/http://www.aip.com.au/pricing/facts/Facts_about_Diesel_Prices.htm|archive-date=2008-07-19|url-status=dead}}</ref> diesel fuel may be priced higher than petrol per [[gallon]] or [[liter]].<ref>{{cite web|url=http://tonto.eia.doe.gov/oog/info/gdu/gasdiesel.asp|archive-url=https://web.archive.org/web/20010815085245/http://tonto.eia.doe.gov/oog/info/gdu/gasdiesel.asp|url-status=dead|archive-date=2001-08-15|title=Gasoline and Diesel Fuel Update - Energy Information Administration}}</ref><ref>{{cite web | url=https://carplus.co.uk/magazine/petrol-vs-diesel/ | title=Petrol vs. Diesel: Should I Buy a Diesel Car in 2022? &#124; Carplus }}</ref> Reasons for higher-priced diesel include the shutdown of some refineries in the [[Gulf of Mexico]], diversion of mass refining capacity to gasoline production, and a recent transfer to [[ultra-low-sulfur diesel]] (ULSD), which causes infrastructural complications.<ref>{{Cite web |url=http://www.eia.doe.gov/bookshelf/brochures/diesel/dieselprices2006.html |title=A Primer on Diesel Fuel Prices |publisher=Energy Information Administration |access-date=2007-03-27 |archive-url=https://web.archive.org/web/20070317055519/http://www.eia.doe.gov/bookshelf/brochures/diesel/dieselprices2006.html |archive-date=2007-03-17 |url-status=dead }}</ref> In Sweden, a diesel fuel designated as MK-1 (class 1 environmental diesel) is also being sold. This is a ULSD that also has a lower aromatics content, with a limit of 5%.<ref>[http://www.criterioncatalysts.com/static/criterion-gb/downloads/pdf/technical_papers/cri707ertc06.pdf]{{dead link|date=September 2017|bot=InternetArchiveBot|fix-attempted=yes}}</ref> This fuel is slightly more expensive to produce than regular ULSD. In Germany, the fuel tax on diesel fuel is about 28% lower than the petrol fuel tax.
