How do you calculate greenhouse gas emissions from diesel?

How do you calculate greenhouse gas emissions from diesel?

1 liter of diesel weighs 835 grammes. Diesel consist for 86,2% of carbon, or 720 grammes of carbon per liter diesel. In order to combust this carbon to CO2, 1920 grammes of oxygen is needed. The sum is then 720 + 1920 = 2640 grammes of CO2/liter diesel.

How much CO2 is produced making a diesel car?

The CO2 emissions from petrol and diesel are around 2.4 kg per litre [1], i.e. 10.9 kg per gallon (since 1 gallon is 4.546 litres).

Does diesel contribute to greenhouse gases?

The U.S. Energy Information Administration (EIA) estimates that in 2019, diesel (distillate) fuel consumption in the U.S. transportation sector resulted in the emission of 456 million metric tons of carbon dioxide (CO2), a greenhouse gas.

How do you calculate greenhouse gas emissions?

GHG emission = 0.001 * Fuel Usage * High heat value *Emission factor. You can get these values from the EPA’s GHG Reporting Program (GHGRP) documentation and your own records.

How are diesel engine emissions calculated?

Report actual emissions in tons/year. Calculate actual emissions using one of the following methods: If the emission factor is in units of pounds per quantity of fuel (gallons or cubic feet): Actual emissions (tpy) = Emission Factor (lb/unit) x Actual Annual Fuel Use (unit) x ([100 – Control Efficiency] ÷ 100)

How much of greenhouse gases are from cars?

In 2019, greenhouse gas emissions from transportation accounted for about 29 percent of total U.S. greenhouse gas emissions, making it the largest contributor of U.S. greenhouse gas emissions.

Does diesel or gas pollute more?

However, in truth, gasoline is a greater polluter than diesel. That fact is equally indisputable. “While diesel fuel contains slightly more carbon (2.68kg CO₂/litre) than petrol (2.31kg CO₂/litre), overall CO₂ emissions of a diesel car tend to be lower.

How do you determine if a gas is a greenhouse gas?

For each greenhouse gas, a Global Warming Potential (GWP) has been calculated to reflect how long it remains in the atmosphere, on average, and how strongly it absorbs energy. Gases with a higher GWP absorb more energy, per pound, than gases with a lower GWP, and thus contribute more to warming Earth.

How much CO2 is in a litre of diesel?

around 2.62 kgs
Burning a litre of diesel produces around 2.62 kgs of carbon dioxide, whereas petrol has a lower carbon content and produces about 2.39 kgs.
