Encouraging Low Carbon Food Shopping with Ubicomp Interventions

食物产生的温室气体占英国碳足迹的10%以上。智能手机应用程序等与碳相关的食品干预措施主要针对的是超市购物者在店内的决定，但几乎没有显示出影响的证据。要想真正切合实际，我们必须寻求对超市内外食品获取的细微差别的理解：其中包括家庭用餐的谈判和规划，以及对外卖和方便食品的定位。我们将利用人种学观察、互动设计、碳特征分析和众包等多学科方法，反复开发和试验有意义地支持食品获取和碳意识的低技术和高科技干预措施，目的是促进影响较小的食品实践。将与超市本身的持续互动纳入研究计划。探索机会，在其作为数万人的粮食机构的作用下，进行可扩展的、持续的削减。

The greenhouse gases arising from food account for more than ten percent of the UK carbon footprint. Carbon-related food interventions such as smartphone apps have largely targeted supermarket shopper decisions 'in store' and have yet shown little evidence of impact.To be truly relevant, we must seek nuanced understandings of food acquisition both within and beyond the supermarket: these include the negotiation and planning of household meals, and positioning with respect to take-away and convenience foods.Using multidisciplinary methods as diverse as ethnographic observation, interaction design, carbon profiling and crowdsourcing, we will iteratively develop and trial both low and high tech interventions which meaningfully support food acquisition and carbon awareness, with the aim of promoting lower impact food practice.Built into the research programme is continual engagement with the supermarket itself, to explore opportunities for making scalable, sustained reductions, in its role as a food institution for tens of thousands.
