How much tailpipe carbon dioxide (CO 2) is created from burning one gallon of fuel? CO 2 emissions from a gallon of gasoline: 8,887 grams CO 2 / gallon; CO 2 emissions from a gallon of diesel: 10,180 grams CO 2 / gallon
Burning biofuels results in emissions of carbon dioxide (CO 2), a greenhouse gas.However, according to international convention, CO 2 emissions from biofuel combustion are excluded from national greenhouse gas emissions inventories because growing the biomass feedstocks used for biofuel production may offset the CO 2 produced when biofuels are burned.

Diesel: approximately 86.2% carbon (720g) There’s an easy formula we can use to provide the total approximate weight of carbon dioxide produced: Weight of carbon in one litre of fuel divided by the molar weight of carbon multiplied by the molar weight of carbon dioxide. Diesel: 724g/12*44=2.65kg. Petrol: 640g/12*44=2.35kg.
So, while diesel fuel contains slightly more carbon (2.68 kg CO₂/litre) than petrol (2.31 kg CO₂/litre), overall CO₂ emissions of a diesel car tend to be lower due to higher efficiency. In use, on average, this equates to around 200 g CO₂/km for petrol and 120 g CO₂/km for diesel.
If congestion mitigation raises average traffic speed to above about 65 miles per hour, it can increase CO2 emissions. And, of course, speeds above 65 or 70 also make the roadway more dangerous. • Smoothing the stop-and-go pattern of traffic so that cars move at a relatively constant speed will reduce CO2 emissions.
Ecology portal. v. t. e. Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, [1] or coal. According to the type of engine, it is discharged into the atmosphere through an exhaust pipe, flue gas stack, or propelling nozzle. A typical passenger vehicle emits about 4.6 metric tons of carbon dioxide per year. This assumes the average gasoline vehicle on the road today has a fuel economy of about 22.0 miles per gallon and drives around 11,500 miles per year. Every gallon of gasoline burned creates about 8,887 grams of CO 2. Are there other sources of greenhouse gas In the worst case scenario, an electric car with a battery produced in China and driven in Poland still emits 37% less CO2 than petrol. And in the best case scenario, an electric car with a battery produced in Sweden and driven in Sweden can emit 83% less than petrol. We also see that electric cars bought in 2030 will reduce CO2 emissions four Emissions factors quantify the average CO₂ output per unit of energy. They are measured in kilograms of CO₂ per megawatt-hour (MWh) of energy from various fossil fuel sources.
As a result, FFVs running on high-level blends of ethanol produce less net CO 2 than conventional vehicles per mile traveled. A 2020 analysis by Argonne National Laboratory found that using corn-based ethanol in place of gasoline reduces life cycle GHG emissions on average by 40%. Using cellulosic ethanol provides an even greater benefit.
Full figures and fact sheets for each car are now available from Green NCAP.All cars tested between 2019 and 2021. As you can see in the table above, the Ford Mustang Mach-e electric car (full review coming soon) is calculated to produce more GHG than the diesel-powered Skoda Octavia.

Diesels are, generally speaking, more fuel-efficient than petrol models and they do produce less CO2 - one of the main gases associated with climate change. As Chancellor, Gordon Brown introduced Gas-powered cars produce almost three times as many pounds of well-to-wheel emissions as all-electric vehicles. But all-electric vehicles still produce 3,932 pounds [1] of emissions in an average year. Emissions from plug-in hybrid and hybrid vehicles (which use both gasoline and electricity) produce about 2,000 pounds more in emissions than The continued global rise in sales of SUVs pushed their climate-heating emissions to almost 1bn tonnes of carbon dioxide in 2022, according to the International Energy Agency. and diesel cars The difference between any two vehicles with the same fuel type (such as gasoline) then comes down largely to miles per gallon. In this case, an F-150 that gets 21 mpg would emit 423 grams of CO2 per mile, whereas a Corolla getting 34 mpg would emit 261 grams per mile. In other words, 8,887 g/CO2 divided by 21 is 423 grams and 34 mpg is 261. How can burning 2,000 pounds of coal yield more than 4,000 pounds of carbon dioxide? When coal is burned, the carbon in the coal combines with oxygen to form carbon dioxide. One molecule of carbon dioxide is 3.67 times heavier than a molecule of carbon, due to the additional weight of the two oxygen atoms.

Someday it might make sense to fill cars with hydrogen. There are 19,253 SCF of carbon dioxide in one metric ton, so 1 million SCF of hydrogen will produce 13 metric tons of carbon dioxide

“On average, electric vehicles will emit half the CO2 emissions of a diesel car by 2030, including the manufacturing emissions,” said Yoann Le Petit, a spokesman for the T&E think tank, which KVU1nVw.
