Fleet emissions for transportation In $2020,$ the weighted average combined fuel efficiency of cars and light trucks in the US$,$ combined, was $18\mathrm{.}2$ miles per gallon. The average vehicle traveled about $11,800$ miles in $2020.$ Assume for the calculations below, that the $2020$ data is applicable to all registered vehicles. In $2020,$ there were nearly $14\mathrm{.}2$ million registered vehicles in California. $1.$ Calculate the fleet emissions of CO$2$ from California in $2020\mathrm{.}2.$ It is estimated that there were approximately $280$ million register vehicles in the US in $2020.$ Calculate the emissions of CO$2$ from all automobiles in the US in $2020\mathrm{.}3.$ By the year $2050,$ it is estimated that there will be perhaps $400$ million automobiles in US$.$ If this happens, and we assume driving conditions stay approximately the same, what would the CO$2$ emissions from automobiles be in $2050$ in the US$?4.$ India had about $300$ million automobiles in $2020.$ While driving conditions and automobile types are much different than in the US$,$ what will the emissions of CO$2$ be from automobiles in India, if the gas mileage and driving patterns were the same as those in the US$?5.$ By the year $2050,$ India is expected to be the largest automobile market in the world. Goldman Sachs has estimated that there will be more than $610$ million automobiles in India by $2050.$ If this happens, and we assume driving conditions stay approximately the same, what would Indias CO$2$ emissions from automobiles be in $2050?6.$ Create a bar graph that illustrates the number of vehicles and CO$2$ emissions from scenarios a$-$e$.7.$ How does this compare to annual overall global CO$2$ emissions $-$ Pick any year between $2020$ and the currently available data?
