High consumption of red and processed meat increases the risk of several chronic diseases. Many people, especially in high-income countries, eat more meat than recommended by nutritional and health agencies. Meat production also has negative impacts on the environment and contributes to climate change. Therefore, climate protection, besides health or animal welfare, could motivate individuals to eat less meat. Willingness to reduce meat consumption and motives to do so are not yet fully understood.
Based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) extended guidelines, a scoping review of peer-reviewed original studies will be conducted to address three questions: What is the evidence regarding (1) the willingness of individuals to reduce meat consumption to mitigate climate change, (2) the awareness of individuals about the link between their meat consumption and the potential to mitigate climate change and (3) individuals having reduced meat consumption for the reason of climate protection? We will search the databases Medline (via PubMed), Scopus, Embase, Greenfile (via Ebsco) and PsynDex/CurrentContent/Agris (via Livivo) using a systematic search string. Studies from 2015 onwards, published in English, German, Danish or Dutch, will be included. We will include observational studies, qualitative studies, intervention studies (if they include surveys) and reviews. Data will be summarised in a narrative synthesis, comprising methods, population characteristics, meat type under study, indicators measured and limitations. Key findings will be grouped according to the research questions. This scoping review will help clarify the role of climate protection in individual reduction of meat consumption and identify research gaps in this field.
Formal ethical approval is not required, as primary data will not be collected in this study. Findings of this scoping review will be presented at scientific conferences and published in a peer-reviewed journal.
大量食用红色肉类和加工肉类会增加罹患多种慢性疾病的风险。许多人，尤其是高收入国家的人，摄入的肉类超过了营养和健康机构的建议量。肉类生产也对环境造成负面影响，并导致气候变化。因此，除了健康或动物福利之外，气候保护也可能促使个人减少肉类消费。个人减少肉类消费的意愿和动机尚未得到充分理解。
根据系统评价和荟萃分析扩展的首选报告项目（PRISMA-ScR）扩展指南，将对同行评议的原始研究进行范围综述，以解决三个问题：（1）个人减少肉类消费以减轻气候变化的意愿的证据，（2）个人对其肉类消费与减轻气候变化潜力之间联系的认识，以及（3）个人出于气候保护原因减少肉类消费的情况。我们将使用系统搜索字符串在 Medline（通过 PubMed）、Scopus、Embase、Greenfile（通过 Ebsco）和 PsynDex/CurrentContent/Agris（通过 Livivo）数据库中进行搜索。纳入 2015 年以后发表的英文、德文、丹麦文或荷兰文的观察性研究、定性研究、干预研究（如果它们包括调查）和综述。将使用叙述性综合方法汇总数据，包括方法、人口特征、研究中的肉类类型、测量的指标和局限性。关键发现将根据研究问题进行分组。这项范围综述将有助于阐明气候保护在个人减少肉类消费中的作用，并确定该领域的研究空白。
本研究不要求正式的伦理批准，因为不会在本研究中收集原始数据。该范围综述的结果将在科学会议上展示，并在同行评议的期刊上发表。
