The amount of carbon dioxide emitted per liter or gallon burned varies by fuel type, since each type of fuel contains a different amount of carbon per gallon or liter. The ratings reflect carbon dioxide (CO 2), nitrous oxide (N 2 O) and methane (CH 4) emissions, weighted to reflect each gas's relative contribution to the greenhouse effect.
An emission intensity (also carbon intensity or C.I.) is the emission rate of a given pollutant relative to the intensity of a specific activity, or an industrial production process; for example grams of carbon dioxide released per megajoule of energy produced, or the ratio of greenhouse gas emissions produced to gross domestic product (GDP).
Many emissions standards focus on regulating pollutants released by automobiles (motor cars) and other powered vehicles.Others regulate emissions from industry, power plants, small equipment such as lawn mowers and diesel generators, and other sources of air pollution.
It will save about 887,000,000 U.S. gallons (3.36 × 10 9 L) of fuel and reduce carbon dioxide emissions by 8.3 million metric tons. This 2011 single-year standard will use an attribute-based system, which sets fuel economy standards for individual vehicle models, based on the footprint model.
When burned, unleaded gasoline produces 8.91 kg (19.6 lb) of CO 2 per gallon, while diesel produces 10.15 kg (22.4 lb). [23] CO 2 emissions originating from ethanol are disregarded by international agreements however so gasoline containing 10% ethanol would only be considered to produce 8.02 kg (17.7 lb) of CO 2 per gallon.

The purpose of Directive 1999/94/EC of the European Parliament and the Council of 13 December 1999 relating to the availability of consumer information on fuel economy and CO 2 emissions in respect of the marketing of new passenger cars [63] is to ensure that information relating to the fuel economy and CO 2 emissions of new passenger cars ...
Canada's Imperial Oil is proceeding with plans to build a 20,000-bpd renewable diesel plant near Edmonton which will be able to produce the fuel cheaper than it would have cost them to import from ...
A gasoline engine burns a mix of gasoline and air, consisting of a range of about twelve to eighteen parts (by weight) of air to one part of fuel (by weight). A mixture with a 14.7:1 air/fuel ratio is stoichiometric, that is when burned, 100% of the fuel and the oxygen are consumed.
