Explanation:

Most of the emissions of anthropogenic greenhouse gases come from the burning of fossil fuels, which include coal, natural gas and oil. However, out of these, oil is the leading cause of increased levels of carbon dioxide in the atmosphere. This occurs when the oil is burned in order to produce energy. In 2018, nearly 45% of greenhouse gas emissions in the United States came from the burning of oil.
