Comments and Suggestions for Authors

Comment: In this manuscript, Chiara Rossi et.al. Start by evaluating dairy products using life cycle assessment methods and discuss some strategies to reduce greenhouse gas emissions from dairy products throughout their life cycle, i.e. carbon sinks. Dairy farm capacity is the main means of mitigating climate change in the dairy supply chain. Overall, there are some issues that need to be addressed before going any further. Some opinions are listed below: 1. Figure 2 Figure 3 The ordinate value is not clearly expressed. Please correct. 2. The article mentioned that 63 consumers participated in the study. Whether the data collected from these 63 consumers is reasonable and whether the number of consumers has a great impact on the consumer research. Please explain accordingly. 3. As shown in Figure 2, the production and consumption stages of one kilogram of aged cheese account for a large proportion of more than 14% of the total carbon emissions, which does not meet the figures. Please confirm the results, and if there is no objection, please explain the situation.
