Anthropogenic climate change is a global problem that affects every country and each individual. It is largely caused by human beings emitting greenhouse gases into the atmosphere. In general, a small percentage of the population is responsible for a large amount of emissions. This paper focuses on high emitters and their CO₂ emissions from energy use in UK homes. It applies a cluster approach, aiming to identify whether the high emitters comprise clusters where households in each cluster share similar characteristics but are different from the others. The data are mainly based on the Living Cost and Food survey in the UK. The results show that after equivalising both household emissions and income, the high emitters can be clustered into six groups which share similar characteristics within each group, but are different from the others in terms of income, age, household composition, category and size of the dwelling, and tenure type. The clustering results indicate that various combinations of socioeconomic factors, such as low-income single female living in an at least six-room property, or high-income retired couple owning a large detached house, could all lead to high CO₂ emissions from energy use at home. Policymakers should target each high-emitter cluster differently to reduce CO₂ emissions from energy consumption at home more effectively.

通过聚类分析了解英国的高排放家庭

人为的气候变化是一个全球性问题，影响到每个国家和每个人。这主要是由于人类向大气中排放温室气体。通常，一小部分人口负责大量排放。本文重点介绍高排放物及其CO ₂英国家庭能源使用产生的排放。它采用集群方法，旨在确定高排放者是否包括集群，其中每个集群中的家庭具有相似的特征但彼此不同。数据主要基于英国的生活成本和食物调查。结果表明，在使家庭排放量和收入均等后，高排放者可以分为六类，每组在各族群中具有相似的特征，但在收入，年龄，家庭组成，类别和规模方面却彼此不同。住所和保有权类型。聚类结果表明，社会经济因素的各种组合，例如生活在至少六居室财产中的低收入单身女性，或拥有大型独立式住宅的高收入退休夫妇，₂家庭能源使用产生的排放。政策制定者应针对每个高排放者群制定不同的目标，以更有效地减少家庭能源消耗中的CO ₂排放。
