The answer to this question depends on the specific gases being compared, as different gases have different warming potentials. However, in general, transportation is a major contributor to greenhouse gas emissions and produces more greenhouse gases than agriculture. According to the US Environmental Protection Agency (EPA), transportation accounted for 28% of greenhouse gas emissions in the United States in 2018, while agriculture accounted for 9%. Therefore, we can estimate that for every pound of warming gas produced by agriculture, transportation produces more than one pound of warming gas.
Out of the given options, the closest answer would be 1.3 pounds of gas produced by transportation for every pound of warming gas produced by agriculture. However, it is important to note that this is only an estimate and the actual ratio may vary depending on the specific gases being compared and other factors.
