Research On The Effect Of Environmental Information Intervention On The Low-Carbon Diet Of The Public

In response to the climate crisis,countries have advocated low-carbon economy and sustainable development.At present,the greenhouse gases produced by the food system are on the rise.The agricultural production stage is the period when the food supply chain produces the highest carbon emissions,and the production of animal foods such as dairy products produces more greenhouse gases than plant foods.Since production is ultimately driven by consumer demand,changing the diet,especially reducing the consumption of dairy products,is a key measure to promote carbon emissions reduction and is of great significance to achieving climate goals.However,the increased consumption of dairy products under the COVID-19 has made the problem of food carbon emissions more serious.The public has insufficient knowledge of the carbon emissions caused by the production of dairy products,and academics have also lacked research on the public’s knowledge of low-carbon diets.This paper uses the method of random controlled trials to explore the effect of environmental information intervention on the public’s intake of dairy products.First,based on the research content and related theories,put forward research hypotheses from the effect of environmental information intervention on the intake of dairy products,and establish the corresponding measurement model;secondly,introduced the design plan and sample selection,baseline survey,random allocation,intervention implementation and final evaluation survey implementation process of this experimental project;thirdly,the variables and the related content of the base period balance test and the loss test are shown;Then,the quantitative model was used to test the impact of environmental information intervention on the intake of dairy products,and to further explore whether the impact of environmental information intervention on the public’s intake of dairy products in different income groups showed differences;finally,the research conclusions were summarized based on the research results,And put forward corresponding suggestions based on the conclusion.First of all,under the intervention of environmental information,the public’s intake of dairy products has not significantly decreased.Although the public recognizes that dairy products produce a lot of greenhouse gases during the production process,they have not significantly reduced their intake of dairy products.Due to the existence of cognitive-behavioral bias and unchanged environmental preferences,environmental interventions have not had the expected effect.Under the intervention of immunity information and joint information,the public’s intake of dairy products has increased significantly,which is manifested in that under the intervention of immunity,the public’s intake of dairy products has increased by 399.47g;under the joint intervention,the public’s intake of dairy products The amount increased by 273.44g.Secondly,in terms of internal mechanisms,environmental information intervention has promoted the improvement of public environmental awareness,but the environmental preference score has not increased significantly,and the improvement of public environmental awareness has not effectively translated into a reduction in the intake of dairy products.Immunity intervention and joint intervention have significantly improved the public’s awareness of immunity and the score of immunity preference.Both are the pathways for information intervention to promote the increase in the public’s intake of dairy products.Finally,the heterogeneity analysis showed that compared with the low-income group,the negative impact of environmental intervention on the public dairy intake was relatively greater in the high-income group,while the positive impact of combined intervention on the public dairy intake was relatively smaller in the high-income group.Since the altruistic level of high-income group is significantly higher than that of the general group,it shows more altruistic behavior under the intervention of environmental information.Based on the research conclusions,this article puts forward the following suggestions:(1)Guide the public to pay attention to carbon emissions and optimize the content of environmental information transmission;(2)Locate altruistic groups and deliver environmental information to the target groups;(3)Improve the design of carbon tax for food consumption,Increase the public’s consumption cost of high-carbon food.
