Public transit substantially reduces fuel use and greenhouse gas emissions, making it a wise public investment in a new, carbon-constrained economy. A typical passenger car carrying one person gets 25 passenger miles per gallon, while a conventional bus at its capacity of 70 (seated and standing) gets 163 passenger miles per gallon. "If you take the cleanest 10% of diesels and the dirtiest 10% of petrol cars, then actually the petrol models will have double the NOx emissions of the diesel ones" says Mr Molden. The report claims that PHEVs produce 2.5 times more CO2 in real life than they do in the lab, with both the BBC and which is much closer to the value for petrol and diesel cars of 164-7g per Kg CO 2 per litre of diesel vehicles. Diesel produces 2.6391 kgs of CO 2 per litre burnt. The precise figures depend on the quality of the fuel. Since fuel weighs less than a kilogram per litre, it is interesting to see how the weight of emissions is multiplied by the addition of oxygen. According to the U.S. Department of Energy, " [h]ighway vehicles release about 1.7 billion tons (1.5 billion metric tons) of greenhouse gases (GHGs) into the atmosphere each year — mostly in the form of carbon dioxide (CO2) — contributing to global climate change. Each gallon of gasoline you burn creates 20 pounds (9 kilograms) of GHG. A 100% sulphur dioxide reduction is reasonable taking into account that biodiesel, by its vegetal origin, does not contain sulphur. The CO emissions for biodiesel combustion in diesel engines are 40 to 50% lower than those for conventional diesel; this happens due to the presence of oxygen molecules in the biodiesel, mainly in the methyl or ethyl ester, helping to obtain complete combustion. What is the CO2 output per litre of diesel? Per litre of diesel fuel utilized, diesel engines emit 2.7 kg of CO2. CH4 is a flammable gas that is colorless and odorless. It has a global warming potential of more than 20 times that of CO2 and can last for up to 12 years in the atmosphere. What is the CO2 output of a diesel car? The EEA has published the provisional data for the average CO 2 emissions from new passenger cars and vans registered in the EU and in Iceland in 2018. After a steady decline from 2010 to 2016, by almost 22 grammes of CO 2 per kilometre (g CO 2 /km), average emissions from new passenger cars increased in 2017 by 0.4 g CO 2 /km. .
