Abstract
The environmental detriments of the growing global production and overconsumption of beef, including greenhouse gas emissions, deforestation, and biodiversity loss, are well-documented. However, public awareness of how dietary choices affect the environment remains limited. This study examines sustainability views on beef consumption and the potential for behavioral change as a step toward more sustainable intake levels. An observational web-based survey was conducted (n = 1367) to assess respondents’ current beef intake frequency, views on beef consumption related to planetary health, tropical deforestation, greenhouse gas emissions, and climate change, and willingness to modify beef consumption behavior. Chi-square tests were used for group comparisons, and weighted average scores were applied to rank levels of resistance to reducing beef intake. Environmental concern related to beef consumption was associated with greater beef cutback intentions and lower long-term intake reduction resistance amongst beef eaters. Beef eaters who strongly agreed that global beef consumption negatively impacts the environment were considerably more likely to express intentions to reduce their long-term beef intake compared to those who strongly disagreed (94.4% vs. 19.6%). Overall, 76.6% of beef eaters indicated wanting to eat less beef or phase it out entirely (30.7% reduce, 29.4% minimize, 16.6% stop), with only 23.4% of them intending to keep their consumption unchanged. Compelling messages that help translate awareness into action, such as the #NoBeefWeek concept explored in this study, may support individuals in adopting more sustainable food choices. These cross-national findings provide evidence for a ‘knowledge-intent’ gap in sustainable diet research, with relevance for health communicators and policymakers. Future research could examine the factors and motivations influencing decisions to modify beef consumption, including the barriers to achieving sustainable consumption levels and the role of suitable alternatives in facilitating this transition.
Generated Summary
This research article details the results of an observational web-based survey that assessed international respondents’ views on beef consumption and its sustainability implications. The study employed a non-probabilistic, opportunity sampling method, distributing a questionnaire to over 100,000 email subscribers of The Health Sciences Academy. The survey focused on assessing current beef intake frequency, views on beef consumption related to planetary health, deforestation, greenhouse gas emissions, climate change, and human health, as well as the willingness to modify beef consumption behavior. The study also assessed the potential for behavioral change under a hypothetical #NoBeefWeek concept and long-term change intentions. Chi-square tests and weighted average scores were used to analyze the data, aiming to explore the connection between environmental perspectives, long-term change intentions, and the role of the #NoBeefWeek concept. The primary goal of the research was to examine public perceptions, and intentions concerning beef consumption to contribute to the development of strategies and policies aimed at promoting more sustainable diets. The study’s approach encompasses a cross-national perspective, providing evidence for a ‘knowledge-intent’ gap in sustainable diet research, highlighting relevance for health communicators and policymakers.
Key Findings & Statistics
- A total of 1367 respondents were included in the final analysis.
- The study found that 76.6% of beef eaters indicated wanting to eat less beef or phase it out entirely.
- 30.7% of beef eaters indicated wanting to reduce beef consumption, 29.4% indicated minimize beef consumption, and 16.6% indicated stopping beef consumption entirely.
- Only 23.4% of beef eaters intended to keep their consumption unchanged.
- 75.9% of beef eaters stated they were willing to skip beef consumption for one week as part of the #NoBeefWeek concept.
- Two-thirds (66.6%) of all respondents, including both beef eaters and beef avoiders, reported that they were either ‘likely’ or ‘extremely likely’ to encourage others to skip beef during #NoBeefWeek.
- The study indicated that beef production requires more land and water, and generates higher greenhouse gas emissions, compared to other animal protein sources.
- Globally, livestock production is linked to 14.5% to 18% of all human-induced greenhouse gas emissions, with beef cattle being the largest single source, accounting for 41% of the sector’s emissions.
- 7 in 10 (67.9%) respondents believed their interest in the planetary health effects of beef consumption had increased from completing the survey.
- 40.8% of respondents had no involvement in the nutrition or health profession, while 43.1% affirmed being a nutrition or health professional, and 16.2% said they were studying for a career in these fields.
- The study revealed that daily beef eaters exhibited the greatest resistance to long-term beef intake cutbacks, with 67.9% of them wanting to keep their long-term consumption unchanged.
- About 3 in 4 beef eaters (76.6%) indicated wanting to eat less beef or even phase it out in the long run.
- The study shows that the most prevalent long-term intention amongst beef eaters was to cut back their beef consumption.
- In contrast, intentions to limit one’s own beef intake in the long term were almost unanimous (94.4%) amongst those who strongly agreed on all five statements that beef consumption and livestock production are harmful to the environment.
- Over two thirds (67.8%) of respondents agreed with all six statements presented to them in varying degrees.
- 75.5% of respondents agreed that beef consumption negatively impacts planetary health and 69.6% that it negatively impacts human health.
- 71.5% of respondents agreed that ‘Beef consumption results in more greenhouse gas emissions than plant-food consumption’.
- 69.8% of respondents agreed that “The livestock industry is the biggest contributor of global greenhouse gas emissions from food production”.
- About 3 in 4 beef eaters (76.6%) indicated wanting to eat less beef or even phase it out (i.e., 30.7% reduce, 29.4% minimize, 16.6% stop), with only 23.4% of them intending to keep their consumption unchanged.
- Amongst respondents, 58.1% agreed that “Beef consumption is one of the main causes of global climate change”.
- 62.1% of respondents agreed that “Beef consumption is the leading cause of deforestation in the Amazon and other tropical forests”.
Other Important Findings
- Environmental concern related to beef consumption was associated with greater beef cutback intentions and lower long-term intake reduction resistance amongst beef eaters.
- Beef eaters who strongly agreed that global beef consumption negatively impacts the environment were considerably more likely to express intentions to reduce their long-term beef intake compared to those who strongly disagreed.
- The vast majority of beef eaters found most of the listed beef products ‘easy’ or ‘extremely easy’ to give up for at least one week.
- The study revealed that the most prevalent long-term intention amongst beef eaters was to cut back their beef consumption.
- Greatest Resistance to Long-Term Intake Cutbacks Amongst Frequent Beef Eaters: Daily beef eaters exhibited the greatest resistance to long-term beef intake cutbacks, with 67.9% of them wanting to keep their long-term consumption unchanged, and only 7.1%, 14.3%, and 10.7% intending to reduce it, minimize it, or stop it (respectively).
- Conversely, those who reported the lowest beef consumption frequencies were the most willing to further reduce and even phase out their intake in the long run, compared to the more regular beef eaters.
- There is a clear correlation between environmental concern and intentions to reduce beef consumption.
- Respondents who strongly agreed that beef consumption has negative environmental impacts were more likely to express intentions to cut back on beef intake.
- The findings underline the potential feasibility for prospective initiatives like #NoBeefWeek to raise awareness and encourage short-term behavioral changes in beef consumption.
- The high acceptance rates observed indicate a growing public willingness to consider the environmental impacts of their personal dietary choices and the demand they create.
- However, the greater resistance among daily beef eaters highlights the deeply entrenched sociocultural and dietary habits that prioritize beef as a staple food.
Limitations Noted in the Document
- The study’s non-probabilistic sampling method, while facilitating ease of participant recruitment, limits the generalizability of the findings.
- Self-selection bias, inherent in opportunity sampling, may have influenced the results.
- The recruited population (students and subscribers of The Health Sciences Academy and True Health Initiative) likely possessed a higher level of environmental health literacy than the general public.
- The study’s reliance on an observational survey prevents the establishment of causal relationships between environmental impact awareness, acceptance of concepts like #NoBeefWeek, and actual long-term changes in beef consumption.
- The study’s analysis did not explore the reasons or motivations behind the change intentions or any resulting eating behavioral change.
Conclusion
The study underscores the critical need for public education to establish a clear link between consumer demand, supplier practices, and environmental consequences related to beef production. The high acceptance of the #NoBeefWeek concept indicates a public openness to consider the environmental impact of their dietary choices. However, entrenched dietary habits of daily beef eaters present a challenge. The study highlights that comprehensive communication strategies should address barriers to change, and policymakers should focus on developing strategies that inform the public about environmental impacts and encourage actionable steps. Future research should assess the effectiveness of dietary change campaigns. The study suggests that providing accessible alternatives, like those of plant-based and meat-mimicking products, might support sustainable changes in consumption patterns. In light of these findings, the study strongly suggests that there is a need for public awareness and acceptance to drive changes in the environmental impacts of beef consumption. Encouraging people to modify their dietary habits could result in positive changes to the environment. This would be a very important outcome that would make a significant impact on many of the environmental concerns that have been raised regarding beef production.
