Reviewer 1 Report

Comments and Suggestions for Authors

11)      The results of the survey and the binary logistic regression must be listed in the Abstract, which must be commented on.

22)      In chapter "1.2. Review of the literature", statistical data on the total worldwide (Europe, USA, Asia...) plastic packaging waste as well as statistical data on the market for organic vegetables must be included.

33)      It is very important to mention whether this statement refers to Ireland or globally to the world (lines 222-224) - "Additionally, given the present economic setting, including rising food prices (there was an 11.7% increase in food and non-alcoholic beverage prices between Dec 2021 and Dec 2022 [42]), ..."

44)      In the Results, I suggest replacing the terms "5c" and "50c" with "0.05 €" and "0.50 €".

55)      Since the results of the survey are summarised in a single Table 2, I suggest splitting the table into several tables and presenting them in the chapter where the results are discussed.

66)      I suggest merging the discussion after the tables and the "Discussion" chapter so that the same sentences and phrases are not repeated. It should be decided whether the tables should be explained after the presentation of the results or separately in the "Discussion" chapter.

77)      In the Conclusion chapter - The main conclusions of the study must be presented in a short and clear version, without abbreviations and labels. Please correct this sentence: "The significance of 2 of the 3 current purchasing habits proposed here indicates that habits should be used to mediate the attitude-behaviour gap found in sustainability-related research, that arises from biases and wishful thinking."

Reviewer 2 Report

Comments and Suggestions for Authors

The study presents a topic of interest regarding the factors that might be correlated with the willingness to pay for environmentally friendly packages for  leafy greens. I propose some recommendations:

The introduction has to be extended, by presenting more thoroughly the research gap and the structure of the paper.

The literature review has to be correlated more specifically with the hypotheses,  as for each hypothesis to identify some studies used for its foundation. 

The result of testing a hypothesis should be presented as accepting/supporting or rejecting/not supporting it, not by claiming the hypothesis is true/false. 

In data analysis process,  the identification of factors influencing the willingness to pay (WTP) was claimed (rows: 270-271), but the analysis approach evaluates the correlation not the causal relationships. Furthermore, the chi-square value has to be presented for all the relationships, even for those not statistically significant. 

The discussion  section has to be completed with other studies that are in line or in opposition with the results. Also, the conclusions has to outline in greater extent the limitations, the theoretical and managerial implications.

Reviewer 3 Report

Comments and Suggestions for Authors

The research work is interesting as it gives us information on consumers' willingness to pay for sustainable packaging. As the topic in question is sustainable packaging, there is a lack of information in the theoretical part about what sustainable packaging means, its characteristics, costs, etc. Please find attached a document with some comments and suggestions.

Comments on the Quality of English Language

The punctuation must be improved. There are long sentences where the idea is lost a bit.

Reviewer 4 Report

Comments and Suggestions for Authors

The study is quite interesting however there is lack of some substantial informations. It is of key importance to add detailed description of the survey (In method section). Moreover there is no precise characteristic of a study group (sex, age, etc.). Please add this information as well. Plus there is a few typos for instance see page 1 line 36 or page 4 line 165.
