# The Use of Artificial Intelligence for Assessing the Pro-Environmental Practices of Companies
## 3 Results  
### Analysis of Data Obtained from the Questionnaires  
The results were analyzed in scoring tables presented as Supplementary Materials. The column headings represent the questionnaire number, and the rows represent the criteria corresponding to the survey questions. The tables present the original grouping of the questions by the stages of the product's life cycle, which is of key importance for the problem under analysis. The main objective of the development of the scoring tables was to compare the involvement of manufacturing companies in environmental activity at various stages of the product's life cycle. Two identical tables were composed--one for SMEs and one for LEs. Table S1 in the Supplementary Materials presents the assessment of pro-environmental solutions implemented in small- and medium-sized enterprises (SMEs). Table S2 in the Supplementary Materials presents the assessment of pro-environmental solutions implemented in large-sized enterprises (LEs). They contain a summary of results of pro-ecological activities of companies to date from the point-of-view of product life cycles (27 questions--Sections I-IV of the questionnaire). The results concerning the plans and future activities of the companies not connected with the product's life cycle are presented and described in Chapter 5.6. In order to make these tables more readable, the criteria were presented in a short form. In the case of single-choice questions, the exact answer was presented (\"yes\", \"no\", or 0, if the answer was not obtained or obtaining an answer was not possible, e.g., the question was irrelevant to the respondent's business activity). In case of multiple-choice questions, where more than one answer was possible (the company meets more than one of the criteria provided), the number provided was the sum of the marked entries. The positive value of the sum represents a positive influence on the environment; a negative value represents a negative influence on the environment. Each respondent could obtain a maximum of \(m_{pd}\) = 35 positive answers in the \"Product design\" (as the first stage of the product's life cycle, Table 2 above) group of questions if all answers to the questions in this group were \"yes\" (for questions with \"yes/no\" answers) or all the answers would be selected (for the remaining questions in this group). The number of surveyed SMEs is \(n_{SME}\) = 15, i.e., the result of equation \(z_{pd,\,SME}\) = \(m_{pd,\,SME}\)\(n_{SME}\) = 35 \(\times\) 15 = 525 equaled 100% of the positive opinions provided for SMEs surveyed during this stage. The number of surveyed LEs was \(n_{L}\) = 15, i.e., the result of equation \(z_{pd,\,L}\) = \(m_{pd,\,L}\)\(n_{L}\) = 35 \(\times\) 15 = 525 equaled 100% of the positive opinions expressed for the LEs surveyed during this stage. The same calculations were used for the remaining stages of the product's life cycle (\(z_{pm,\,SME}\) = 300 and \(z_{pm,\,L}\) = 300 for product manufacturing, \(z_{pu,\,SME}\) = 450 and \(z_{pu,\,L}\) = 450 for product use, and \(z_{pr,\,SME}\) = 240 and \(z_{pr,\,L}\) = 240 for product recycling). A preliminary analysis of the data was conducted to reveal the implementation of environmental solutions at certain stages of the product's life cycle. This presents the significance of the life cycle phases for both SMEs and LEs and permits the observation of the differences in pro-environmental activities in companies of various sizes (Figure 2). LEs presented a high level of implementation of environmental solutions at the product design and manufacturing stages. The significance of the other stages of the product's life cycle for LEs was relatively steady--all the results are equal to or higher than 20%. The existence of a certain environmental equilibrium is typical for LEs. Most of them have sufficient funds to consider the implementation of environmental solutions at all stages of the product's life cycle.
