Countermeasures of Double Carbon Targets in Beijing–Tianjin–Hebei Region by Using Grey Model
Round 1
Reviewer 1 Report
the work is very interesting overall. The remarks will be more in the form especially at the level of the tables. It would be better to avoid tables straddling two pages like Tables 3, 5 and 6.
I also recommend replacing tables 1, 2 and 3 with histograms if possible. It will be more meaningful in my opinion.
Congratulations again for your excellent work.

Table 1, Table 2, Table 3 and Table 4 in the original text have been changed to a histogram. That is, Figure 2, Figure 3, Figure 4 and Figure 5 in the present paper. At the same time, the Figure of the fourth section is improved. It's clearer than before.
The cross-page issue with tables in this paper has been improved.

Reviewer 2 Report
I quite enjoyed reading this paper. There are two areas you must improve before I may recommend publication of your paper in this journal.
First you need to do proper literature review so that readers know if there are any papers on carbon emission prediction had been published and then you need to highlight what makes your paper original/novel by comparing to these published papers.
Second you need to explain more about fractional accumulation GM (1,1) model and also need to justify why choosing this method to predict carbon peak is the right decision.

Reviewer 2:
- First you need to do proper literature review so that readers know if there are any papers on carbon emission prediction had been published and then you need to highlight what makes your paper original/novel by comparing to these published papers.
The literature review has been improved. From the prediction model of carbon emissions, the analysis of factors affecting carbon emissions, and the analysis of temporal and spatial differences of carbon emissions in specific industries, this paper describes the research papers on carbon emissions published in the past to fully explain the background of carbon emissions research. Thus prove the difference between this study and previous studies, prove the novelty of this paper.
- Second you need to explain more about fractional accumulation GM (1,1) model and also need to justify why choosing this method to predict carbon peak is the right decision
The study design has been improved. In the third part of the paper, the case of calculation using FGM(1,1) is added and its validity is verified. Corresponding to sections 3.2 and 3.3 of the revised paper. At the same time, the reason of choosing the FGM(1,1) model to predict carbon peak time is explained in the third section, and the validity of the FGM(1,1) model is verified to prove the correctness of choosing FGM(1,1) model to predict carbon peak time.
