Livestock hasbeen described as climate change's forgotten sector, contributing an estimated 14.5% of global greenhouse gas emissions, more than direct emissionsfrom the transport sector. Yet none of the 120 national plans to be presented at the COP21 Climate Negotiations in Paris propose reducing meatconsumption. In addition to the implications for climate change this important and overlooked topic also has impacts on land use, food security and publichealth. The research project proposes investigating which interventions are effective in reducing people's meat consumption. Reserach will be carried outwith colleges, retailers and public outlets in collaboration with Cambridge University's Living Laboratory for Sustainability. A number of experiments will becarried out including: 1) Experimental before/after comparisons on meat consumption after the provision of information on the environmental, health andanimal welfare impacts of eating meat. 2) Targeting habitual and automatic behaviours, by changing the prominence, accessibility and opt-in vs op-out ofmeat and vegetarian menu options and foodstuffs. 3) Investigating the permanence of inteventions, do consumption patterns persist after experimentaltreatments stop? 4) Investigating how the effectiveness of interventions varies with age, gender, political views, etc.

畜牧业被描述为气候变化的被遗忘的部门，估计占全球温室气体排放量的14.5%，超过运输部门的直接排放量。然而，在巴黎举行的COP21气候谈判上，120个国家计划中没有一个提出减少肉类消费。除了对气候变化的影响外，这一重要而被忽视的主题还对土地使用、粮食安全和公共卫生产生影响。该研究项目建议调查哪些干预措施能有效减少人们的肉类消费。这项研究将与大学、零售商和公共机构合作，并与剑桥大学的可持续发展生活实验室合作。将进行一些实验，包括：1）在提供有关吃肉对环境、健康和动物福利影响的信息后，对肉类消费进行实验性的前后比较。2)针对习惯性和自动行为，通过改变肉类和素食菜单选项和食品的突出性，可访问性和选择加入与选择退出。3)研究干预的持久性，在实验性治疗停止后，消费模式是否仍然存在？4)调查干预措施的有效性如何随年龄、性别、政治观点等而变化。
