Problem $1$:

A multinational corporation is conducting a comprehensive carbon footprint analysis across its operations, supply chain, and product lifecycle. The following data has been collected for the fiscal year:

Natural Gas Consumption: $1,000,000$ MMBtu

Company Fleet Fuel $($Diesel$)$: $500,000$ gallons

Electricity Purchased: $750,000MWh$

Heating $($purchased steam$)$: $200,000$ MMBtu

Business Travel: $10,000,000$ miles $($air travel, average short$-$haul$)$

Employee Commuting: $5,000,000$ miles $($average car travel$)$

Waste Generated: $25,000$ tons $($non$-$recycled$)$

Purchased Goods and Services: $$500,000,000($spend$-$based method, average emission factor of $0\mathrm{.}1kg$ CO$2$e per dollar spent$)$

Emission Factors:

Natural Gas: $53\mathrm{.}06kgC{O}_2\frac{e}{M}$MBtu

Diesel: $10\mathrm{.}21$kgCCO ${?}_{(})\frac{2}{g}$allon

Electricity: $0\mathrm{.}4kgC\frac{O_{23}}{k}Wh$

Steam: $50kgC{O}_2\frac{e}{M}MBM$

Air Travel $($short$-$haul$)$: $0\mathrm{.}15kgC{Q}_2\frac{e}{m}$ile

Car Travel: $0\mathrm{.}4kgC{O}_2\frac{e}{m}$ile

Waste: $1\mathrm{.}2kgC{O}_2\frac{e}{k}g$

Using the given data, calculate the following:

Define what are scope $\frac{1}{2}\frac{?}{3}$ emissions, and categorize the emissions given under each scope. $($you can find information online on scopes and their definitions, give reference on where you found the information$)$

Calculate the total $C{O}_2$ emissions for each scope and the overall carbon footprint for the fiscal year.

Determine the percentage contribution of each category within each scope to its total emissions; draw pie$-$chart showing category wise contributions.
