Review of “CFC-11 emissions are declining as expected in Western Europe “

This manuscript is well-written and the science discussed is very relevant to global atmospheric emissions, ozone loss and climate change. It also shows the importance of policy decisions to cut global emissions.

Major:

1. I am not sure what you expect and whether you have seen those results from the analysis. This is not discussed anywhere in the text. Also, if you look at the results, there are some years with high emissions. This is also expected? Figure 5, for Benelux, there is a slight positive trend? Therefore, it is better to avoid ”expected” from the title. I do agree that there is a significant reduction in emissions.
2. You have discussed CFC-11, CFC-12 and CCl4 emissions, but the title says just CFC-11?
3. “France also has the highest emissions per capita”, is it also holds good for the other countries mentioned here?

Minor:

Line 9: “, and ”

L10: from 2008 to 2021

L14: any reason for these highest regional emissions or are you talking about the slow decline there?

Abstract: The first 10 lines can be shortened

L40: all active banks are

L49: Is it bank or banks? be consistent in using this

L57: from 2012 to 2017 to understand

L58: In fact, they speculated that, and were not reporting

L106: “, respectively”

L261: any reason for this particular increase in specific years, e.g. 1995-1996?

L289: no single model particularly stands out?

L302: between 2008 and 2021

L304: which emitted less than that of

L308: as shown in Figure 3 panel (e)

Figure 5: Why Benelux shows an increase in the emission of CFC-11?

L341: To understand

Figure 1: font size is too small to read

Figure 4: colour bar is very bad, as there is a repetition of the same (very similar) colour. Please change this colour bar.

Figure 5: Any reason for the particular peaks? For instance, CFC-11 in 2010 in France and 2020 in Germany?
