Encouraging Low Carbon Food Shopping with Ubicomp Interventions

食品产生的温室气体占英国碳足迹的10%以上。与碳相关的食品干预措施，如智能手机应用程序，在很大程度上是针对超市购物者“在店内”的决定，但几乎没有显示出影响的证据。要真正做到相关，我们必须在超市内外寻求对食品获取的细致理解：包括家庭膳食的谈判和规划，以及对外卖和方便食品的定位。采用多学科方法，如人种学观察、交互设计、碳分析和众包，我们将不断开发和试验低技术和高技术干预措施，这些干预措施有意义地支持食品获取和碳意识，旨在促进低影响食品实践。该研究项目还包括与超市本身的持续接触，以探索其作为数万食品机构的角色，实现可扩展的、持续的减排的机会。

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.
