Dear Authors,

The two referees made a number of interesting comments that are united in some aspects (Lack of repetitions, some drawbacks or process not sufficiently considered, comparisons with other studies).

You provided a detailed response to these comments so that I invite you to submit your revised version. Your explanations are sometimes long and complicate concluding it is not necessary to implement the suggestions/comments of the referee in the manuscript. I reaffirm the need to carefully consider the suggestions made by referees and modify your manuscript accordingly. Moreover, I suggest you to include as supplementary materials your mathematical description on how short-term active measurements of CO2 emissions can be linked to long-term passive trapping of emitted CO2.

Once you manuscript will be uploaded, it will be sent to the original referees.

Best regards,

Sébastien Fontaine
