I went through this case and found out that the calculations were strange.

**Exhibit 3: DPDHL Carbon Footprint 2017** - *the calculations are abit off*.

For example, based on my calculation, the total emission should be 2.1 + 9.7 + 14.7 + 2.3 = 28.8 instead of 28.44.

**Exhibit 4: Calculation Quantitative Analysis** - I cant follow the logic; I think the way the author do the computation on excel was poor. Furthermore, I still managed to follow the flow, however, I couldnt get the same results.

1. How to calculate Total Emission for Road and Air?

2. How to get the Total Emission for Overseas Festivals? Should it be a basic summation of Road and Air?

Can someone enlighten me? :)
