Awareness and Practices of Carbon Footprint Reduction: A Survey among Postgraduate Students

The investigators have tried to know the awareness and practices of Postgraduate students studying in various streams of education at the University of Balasore, Odisha, India in reducing carbon footprint. In this study investigators used the stratified random sampling method to select the sample consisted of 180 students, comprising both female and male students. In the study data was collected by using Carbon footprint awareness test and Carbon footprint practices scale constructed by the investigators themselves. The findings revealed that more than half of the students had low level of carbon footprint awareness; whereas no significant difference was found between female and male students in their level of carbon footprint awareness; however students who followed different academic courses had varying degrees of awareness of their carbon footprint. The findings also revealed that half of the students had low level of carbon footprint practices and there exists a statistically significant difference in the mean carbon footprint practice scores of postgraduate students from different streams of education. There is a correlation between carbon footprint awareness and carbon footprint practices as viewed by the postgraduate students. Thus, it can be inferred that as the awareness of carbon footprint increases among postgraduate students, their implementation of practices to reduce carbon footprint also increases.


Introduction
The significant surge in carbon levels in the atmosphere during the 21 st century can be attributed to factors such as population growth, industrialization, and deforestation. Individuals and organizations rely on various forms of energy, such as electricity, coal, and oil, in their daily activities, thereby emitting carbon dioxide into the atmosphere. This carbon dioxide remains suspended in the environment for over a hundred years. The increase in carbon concentration has resulted in global warming, which is a widely discussed and emphasized issue worldwide.
The rise in global temperatures caused by increased carbon levels has led to climate change, bringing about severe consequences such as rising sea levels, extreme weather events, and the loss of biodiversity. Essentially, we are leaving our footprint in the atmosphere, making it challenging for future generations to thrive. Consequently, it becomes the responsibility of every individual to assess and reduce their carbon emissions during their lifetime.
The concerns and awareness surrounding climate change and its consequences can influence household decision-making, prompting the adoption of more climate-friendly practices. This, in turn, contributes to progress towards building a lowcarbon society. Households that prioritize reducing their carbon footprint and actively change their behavior, along with additional incentives like social norms or health benefits, play a significant role in this transition. It is worth noting that environmental awareness and behavior change are closely interconnected.
The factors associated with personal carbon footprints are linked to individuals' knowledge, values, emotions, and perceptions regarding the environment, particularly climate change. Hence, recognizing the urgent need for action in mitigating climate change, understanding the awareness and actions of the younger population is crucial. By exploring their attitudes, knowledge, and behaviors related to carbon footprint reduction, we can gain insights into their role in shaping a sustainable future. By empowering and mobilizing the youth, we can foster a generation that is equipped with the knowledge and motivation to create a greener and more environmentally conscious world.

Population and Sample
The study aimed to examine the awareness of carbon footprint among male and female postgraduate students pursuing diverse educational streams at the University of Balasore, Odisha, India. Additionally, it investigated their efforts in reducing the carbon footprint. Therefore, the study population encompassed all postgraduate students at Balasore University. The researchers considered both the students' educational streams and gender while selecting the sample, employing a stratified random sampling method. Equal numbers of samples were collected from the science, arts, and commerce streams. The entire student body studying across various streams at Fakir Mohan University constituted the population for this study, totaling approximately 1,004 students regardless of gender. Consequently, the data-generating sample comprised 180 students, including both male and female students from the three aforementioned streams. The categorical distribution of the sample is as follows;

Tools of the Study
The present study utilized the following researcherdeveloped tools to collect the required data. The final version of the research tool comprised a total of 25 items. Among these, 15 items followed a 'true or false' format, while the remaining 10 items required participants to select the correct response. Each item was assigned a weightage of 1 mark for a correct response and 0 marks for an incorrect response.

Carbon Footprint Practices Scale
The investigators conducted a comprehensive review of relevant literature and research studies to identify and formulate 40 statements pertaining to personal activities and habits. These statements were designed to be straight forward and easily understandable. Among the 40 statements, there were 17 positive statements and 23 negative statements.
A five-point rating scale was employed to classify the statements, using the following options: Always, Often, Sometimes, Occasionally, and Never. Respondents were requested to select the appropriate option for each statement by placing a check-mark ().
Scoring was determined based on the nature of the statements. Positive statements were assigned scores of 5, 4, 3, 2, and 1 for the options Always, Often, Sometimes, Occasionally, and Never, respectively. Conversely, negative statements were scored in reverse, with options receiving scores of 1, 2, 3, 4, and 5. All necessary precautions were taken during the development of the rating scale.
The content validity of both tools was established by soliciting expert feedback and incorporating their suggestions to modify the items accordingly. The Content Validity Index (CVI) was calculated, and items with a positive CVI were retained, while those with a CVI of 0 or less were discarded.
In order to evaluate the reliability of the research tools, a pilot study was conducted involving 30 postgraduate students. The reliability of the instruments was assessed using the split-half method. The carbon footprint awareness test yielded a reliability value of 0.89, indicating high consistency in measuring carbon footprint awareness. Similarly, the carbon footprint practices scale demonstrated a reliability value of 0.93, indicating strong internal consistency in assessing carbon footprint practices among the participants.

Data Collection Technique
The investigators obtained permission from the respective Heads of Departments and personally visited various departments to distribute the carbon footprint awareness test and carbon footprint practices scale to postgraduate students from different disciplines. After distributing the tools, the participants were briefed about the study's purpose, and the investigators ensured that the respondents understood the objectives. The administration of both tools took approximately 35 minutes. In total, around 220 copies were handed out to selected individuals. However, out of the distributed research tools, only 180 completed and returned sheets were received. Incomplete tools were excluded from the analysis, resulting in a final dataset of 180 valid data samples for further analysis.

Analysis and Interpretation
Level of carbon footprint awareness of students According to the data in Table 1, the majority of postgraduate students (54.44%) are unaware of their carbon footprint. Around 30% of students have a moderate level of awareness, whereas   Based on the data presented in Table 2, the t-value obtained is 0.77, which was found to be statistically insignificant at the 0.05 level. The observed 't' value indicates that there is no significant difference in the level of carbon footprint awareness between female and male students. Therefore, the null hypothesis, which states that there is no significant difference in carbon footprint awareness between male and female students, is accepted at the 0.05 significance level. 15.55% of them have a high level of carbon footprint awareness.

Fig. 2: Level of carbon footprint awareness of post graduate students
The ANOVA result shown in Table -3 indicated that, at the 0.05 level of significance, the f-statistical value 4.28 was found to be bigger than the table value 3.07. As a result, it can be established that the mean carbon footprint awareness scores of postgraduate students from diverse fields of study vary considerably. It suggests that students who followed different academic courses had varying degrees of awareness of their carbon footprint. Hence, the null hypothesis that there is no significant difference in the mean carbon footprint awareness scores of postgraduate students from various educational streams was rejected at the 0.05 level.
Additionally, in order to determine the significance of the difference in mean carbon footprint awareness scores between student groups, a t-test was conducted and the resulting findings are presented in the following table. In the above Table 4, a t-test is applied between the science and arts, arts and commerce, and commerce and science groups. The calculated 't' values of 2.21 and 2.95 were found to be greater than the t-critical value at a significance level of 0.05 for the comparisons between the sciencearts and commerce-science groups, respectively. This indicates that there is a statistically significant difference between these two groups. Therefore, the findings suggest that there is a significant distinction among students in the Science-Arts and Science-Commerce groups in terms of their carbon footprint awareness.
In contrast, at the 0.05 significance level, the calculated t-value for the third group (Arts-Commerce) is 1.03, which is lower than the critical t-value of 1.98 from the table. As a result, the hypothesis stating that there is no significant difference between the mean carbon footprint awareness scores of arts and commerce students is accepted.
In other words, it may be inferred from the mean score that the science students are better at recognizing their carbon footprint in comparison to their counterparts in the arts and commerce streams. Students in both arts and commerce streams are equal in their level of carbon footprint awareness. This implies that students from both disciplines possess similar levels of awareness regarding their carbon footprint.

Fig. 3: Percentage analysis of carbon footprint practice level of students
The data presented in Figure 3 provides a clear visualization of the same information. The overall findings reveal that over 50% of the students included in the study exhibited a low level of carbon footprint practices.
Based on the data presented in Table 6, the calculated 't' value is 1.501, which was determined to be statistically insignificant at the 0.05 level. The observed 't' value indicates that there is no significant difference between female and male students in terms of their carbon footprint practices. Therefore, the null hypothesis, which states that there is no significant difference between male and female students in their carbon footprint practice scores, is accepted at the 0.05 significance level. The ANOVA analysis presented in Table 7 reveals that the calculated F-statistic of 8.005 is greater than the critical table value of 3.04 at a significance level of 0.05. This indicates a significant difference in the mean carbon footprint practice scores among postgraduate students from different streams of education. It suggests that students from various educational backgrounds vary in their carbon footprint practices. Consequently, the null hypothesis, which assumes no significant difference among postgraduate students from different streams of education in their mean carbon footprint practice scores, is rejected at the 0.05 significance level.
Additionally, in order to determine the significance of the difference in mean carbon footprint practice scores between student groups, a t-test was conducted, and the resulting findings are presented in the following table.
In the above Table 8 't' test is applied between the Science-Arts, Arts-Commerce, and Commerce-Science groups. It is learnt that the estimated't' values of 2.14 and 3.98 are greater than the 't' critical value between the Science-Arts and Commerce-Science groups, respectively, at 0.05 level of significance, which means that the difference among the two groups was found to be statistically significant. Thus, the findings showed that there are significant differences among the students in the Science-Arts and Science-Commerce groups.  In contrast, for the third group (Arts-Commerce), the calculated 't' value is 1.86, which is lower than the critical 't' value of 1.98 at the 0.05 level of significance. Therefore, there is no significant difference observed between Arts and Commerce students in terms of their mean carbon footprint practice scores.
In other words, it may be interpreted from the mean scores that the science students are better at their carbon footprint practice level in comparison to their counterparts in the Arts and Commerce streams.
Students in both Arts and Commerce streams are equal in their level of carbon footprint practices.

Relationship between Level of Carbon Footprint Awareness and Adoption of Carbon Footprint Practices
The relationship between carbon footprint awareness level and carbon footprint practices can be established by calculating the coefficient of correlation. The strength and direction of the relationship are indicated by the coefficient of correlation, typically denoted by the letter 'r'." The above table shows the correlation between carbon footprint awareness and carbon footprint practices as viewed by the postgraduate students.
A detailed explanation is given below with the help of the diagram.

Fig. 4: Coefficient of correlation between level of carbon footprint awareness and carbon footprint practices of post graduate students
According to the data presented in Table 9, it is observed that the correlation between carbon footprint awareness and carbon footprint practices is 0.92. The coefficient of correlation, which indicates the strength and direction of the relationship, is positive. Moreover, the correlation is found to be significant at the 0.01 level, further confirming the strong relationship between carbon footprint awareness and carbon footprint practices.
The observed correlation of 0.92 between carbon footprint awareness and carbon footprint practices suggests the presence of a relationship as perceived by the students. Consequently, the null hypothesis, which assumes no significant relationship between carbon footprint awareness and carbon footprint practices among postgraduate students, is rejected at the 0.01 level of significance. These findings also indicate a strong, positive association between activities aimed at reducing carbon footprints and an understanding of carbon footprints.
It may further be interpreted that higher the level of awareness of carbon footprint, the higher is the level of practices for reducing carbon footprint among the post graduate students.

Conclusion
The analysis of results indicates a strong correlation between carbon footprint practices and awareness.
However, the majority of students exhibit a low level of awareness and engagement in carbon footprintrelated practices. To protect the environment, it is crucial to disseminate knowledge and promote actions that minimize carbon footprints. Scientific research demonstrates the critical link between the environment and life, as well as the impact of carbon emissions on ecosystems. The goal of carbon footprint awareness should be to develop a population that understands the issues and is motivated to reduce their carbon footprint. Changes in educational curricula should prioritize environmental education and empower individuals and communities to actively participate in solving environmental problems. Increasing awareness about carbon footprints is vital, as people are more likely to adopt sustainable behaviors when they understand the problems and their consequences. Education efforts can involve public campaigns, school programs, and government policies. By fostering a sense of responsibility and urgency, we can encourage individuals and communities to mitigate climate change by reducing their carbon footprints. Teacher education plays a crucial role in shaping students' awareness and actions, necessitating comprehensive training on carbon footprints. NGOs and the media also have significant roles in raising awareness and disseminating accurate information about carbon footprints. This study's findings offer valuable insights for designing targeted interventions and educational programs to enhance carbon footprint awareness and promote sustainable practices based on gender and educational streams. Taking action to reduce our carbon footprint is essential in addressing climate change, and these findings can inform policymakers and administrators in refining environmental education strategies.
