$9.$ Suppose the cost of the product purchased by Industry A from the outsourced company is $40\%$ more than the cost of in$-$house production but gets a benefit of lesser $CO2$ emissions, then, what $CO2$ tax will make it attractive for the company to buy the product at $40\%$ more cost ten its current cost. Answer philosophically if not by numbers. And if you are the owner of the company what strategies you will adopt? Buy or make or both?

$10.$The UAE's GDP is expected to grow at $7\mathrm{.}1\%$ CAGR for the next $26$ years given its current GDP of $415$ billion dollars. Assume that its energy needs also grow at similar rates. Calculate its energy consumption for $2050$ in MTOE and find the per capita energy consumption capita$).$ Assume projected population growth by $2050.$ Calculate the total $CO2$ emission now and in $2050$ assuming if oil remains the backbone of energy. Assume $2\mathrm{.}36Kg$ of $CO\frac{2}{k}g$ of oil and assume $CV$ as $11,200$kca$\frac{l}{k}g$

$11.$Suppose UAE announces a net zero pathway with a target year of $2050.$ Calculate the renewable energy capacity to be installed by UAE for $2050$ for the above scenario.

$12.$Let's suppose in an realistic situation UAE increases its RE from current level to $80\%$ by $2050$ in a uniform manner $($rest of energy coming from current fossil fuels$).$ Then calculate the total $C{O}_2$ to be removed by $2050.$

$13.$Elaborate Kaya's identity with respect to its component terms.

$14.$Can you calculate each of these terms $($from previous questions$)$ for UAE taking the data available from official websites. Please state the strategies to bring down terms III and IV now and by $2050.$
