Not only do SUVs on average consume about a quarter more energy than medium-size cars, they drive the increase in the automotive industry’s demand for steel. Because of their larger size and poor aerodynamics, SUVs release more tailpipe emissions.

They are also the source
of more carbon emissions during the production phase, making SUVs the second largest cause of rising CO2 emissions between 2010 and 2018, ahead of heavy industry, trucks, aviation and shipping.
For example, Volkswagen’s SUV model, Tiguan, contains an estimated 900 kilograms of steel and approximately
150 kilograms of aluminium. Instead, Volkswagen’s Golf requires only 700 to 750 kilograms of steel and 100 to 120 kilograms of aluminium.
Since 2018, Volkswagen has been producing more Tiguans than Golfs; the increased SUV production means a considerable increase in demand for these metals. In the past ve years alone, the production of Volkswagen Tiguan SUVs required at least 115,350 metric tons more aluminium and 576,000 metric tons more steel than the production of Volkswagen Golf cars. The production of one metric ton of steel releases approximately 1.8 tCO2. The additional consumption of steel by the Volkswagen Tiguan compared to the Volkswagen Golf has therefore led to an additional one million tCO2 released into the atmosphere in the past five years alone
The carbon emission intensity of the power generation technology determines the cleanliness of electricity used by the vehicles. Compared to electricity produced by fossil fuels (coal, oil and natural gas), the CO2 intensity of power generation through renewable energies like photovoltaic (PV) and wind power is dozens of times lower

The CO2 emissions from the production of hydrogen lie somewhere between natural gas and coal fired power.
If fugitive methane emissions are also considered, the total emissions for the whole hydrogen production process could be as high as 550.8g CO2-eq/ kWh.
