How much CO2 is created by making 1 liter of diesel?

The production of 1 liter of diesel fuel generates approximately 2.68 kilograms of carbon dioxide (CO2) emissions when the entire lifecycle is considered, including extraction, refining, and combustion. This figure can vary based on factors such as the type of crude oil used and the efficiency of the refining process. Overall, diesel fuel has a significant carbon footprint due to the fossil fuel-based nature of its production and use.
