Problem $2$:

Average $C{O}_2$ emissions from a car are $114\mathrm{.}1gC{O}_2-e\frac{q}{k}m,$ average particulate matter emitted is approximately $16\mathrm{.}589m\frac{g}{k}m,$ and average NOx emissions are $2\mathrm{.}57\frac{g}{k}m.$ Assume the car travels for $1Mkm$ in its lifetime.

What are mid$-$point and end$-$point methods for life cycle impact assessment? State clearly the definitions and differences.

Calculate both midpoint and endpoint impacts ${?}_{(})$ on all relevant indicators due to the given car in its lifetime. Tabulate and present your results.
