Question:

A cement manufacturing plant is preparing a greenhouse gas $($GHG$)$ emission inventory to assess its carbon footprint. The plant uses various energy sources and materials in its operations. The following data has been provided: Data on consumption & production: The plant consumes $15,000,000kWh$ of electricity annually. The plant uses $5,200,000m^3$ of natural gas per year. The plant produces $15,000$ tons of clinker per annum. Relevant factors for calculation: For electricity; EFco$2$e: $0\mathrm{.}459kgC{O}_2\frac{e}{k}Wh$

For natural gas; NCV: $34\mathrm{.}54T\frac{J}{{10}^6}{m}^3,E{F}_{cO2}$:$53\mathrm{.}67\frac{t}{T}{J}_J,E{F}_{cH4}$:$5k\frac{g}{T}{J}_J,E{F}_{N20}$:$0\mathrm{.}1k\frac{g}{T}J$

For clinker; EFco$2$e: $0\mathrm{.}526$ tons $C{O}_2\frac{e}{?}$ ton of clinker

$100-$year GWP values: $C{H}_4$:$28,N_{2}O$:$265$

Based on this information, provide answers for the following questions:

Calculate the greenhouse gas emissions from electricity consumption: How many tons of $C{O}_2$ e does the plant emit from its annual electricity consumption? Calculate the greenhouse gas emissions from natural gas consumption: What is the total GHG emissions in tons of $C{O}_2$ e due to annual natural gas consumption?

Calculate the greenhouse gas emissions from clinker production: Compute the total process emissions resulting from clinker production in tons of $C{O}_{2}e.$ Calculate the total greenhouse gas emissions for the plant: What is the total annual GHG emission in tons of $C{O}_{2}e$ for the entire plant, considering all the data provided?

Suggest a mitigation measure: Based on the data, suggest one mitigation measure to reduce the plant's greenhouse gas emissions and evaluate its impact.
