Dear Authors,

We would like to see the following change and minor revisions in your paper in order to be published soon. Please address the following changes:

1. Page 13, Line 330, “an increase during …”
2. Page 15, Line 364-370. I think this part represents a comparison but is kinda apart from the context. I suggest rephrase the sentences. For example, “… will be reduced to 27t in 2020. This is much lower than the estimation from our previous study using the transformed normal distribution function...”.
3. Figure 4 has been revised into black/white version as compared with the ACPD version. I think the color one is better.
4. Page 15, Line 384-385, “… were the largest two emission processes, accounting for 49% and 24% of national emissions, respectively.”
5. In table 1, column for NS of Limestone, some numbers “1” are in red, what does it mean?
6. I suggest to add words on the improvement of the method and finding in the conclusion. For example, Line 390 can be extended to specify the innovation and merits of the method and findings compared with previous studies.

Best regards
