Model results: Interpreting the data

After Hawkins team had decided which variables to include in the model, they needed to gather the data to generate values for those variables. They calculated the CO₂ emissions associated with every part of the vehicle. They determined how many miles a typical vehicle is driven during its lifetime (150,000 km). And they looked at the CO₂ emissions from various forms of electricity generation. Ultimately, they presented the total costs associated with three life cycle phases: production, use, and end of life. Below is a table with data representative of, but not taken from, Hawkins research. (Note that the units, kg CO₂e, refer to kilograms of carbon dioxide equivalent, a measure of global warming potential.)

	Production					+	Use					+	End of Life	=	Total Life Cycle
	Battery Materials Extraction and Manufacturing (kg CO2e)		Vehicle Materials Extraction and Manufacturing (kg CO2e)		Production Total (kg CO2e)		kg CO2e per 1000 km driven		1000s of km driven		Use Total (kg CO2e)		End of Life Total (kg CO2e)
ICEV (standard)	0	+	7500	=	7500		200	x	150	=	30000		750		?
ICEV (high-efficiency)	0	+	7500	=	7500		165	x	150	=	24750		750		?
ICEV (less total driving)	0	+	7500	=	7500		200	x	75	=	15000		750		?
EV (electricity from standard mix)	8000	+	7500	=	15500		100	x	150	=	15000		1050		?
EV (electricity from coal)	8000	+	7500	=	15500		200	x	150	=	30000		1050		?
EV (electricity from wind)	8000	+	7500	=	15500		15	x	150	=	2250		1050		?

Calculate the total life cycle kg CO₂e for each of the six vehicles. Use those total values along with the values for each portion of the life cycle to help you drag the bars to their correct places on the bar graph.
