在城市化和其他多种社会经济趋势的推动下，家庭规模缩小是全球趋势。单干会带来巨大的环境挑战，因为从消费规模经济和温室气体影响中获益的可能性没有得到充分利用。换句话说，了解不同消费类别的家庭内部分担模式对减缓气候变化越来越重要。本文探讨了家庭规模、城市结构和生活方式对温室气体的影响之间的关系。当城市向外扩张时，家庭规模也在增长。因此，家庭内部共享的增加似乎减轻了城市扩张对温室气体的负面影响，这是非常合乎逻辑的，但尚未被理解。因此，协作消费的兴起为减少独居者的温室气体排放提供了潜力，并通过家庭间共享来弥补家庭内共享的减少。(C) 2016 Elsevier Ltd.版权所有。
Decreasing household size is a global trend, driven by urbanization and multiple other socioeconomic trends. Going solo poses a great environmental challenge, as the possibility to benefit from scale economies in consumption and its greenhouse gas impacts is not taken advantage of. In other words, understanding of intra-household sharing patterns of different consumption categories is increasingly important in climate change mitigation.This paper explores the relationship between household sizes, urban structures, and greenhouse gas impacts of lifestyles. When urban areas grow outwards, the household sizes also grow. As a result of this, the increase in intra-household sharing seems to alleviate the negative GHG implications of urban sprawl, which is highly logical but yet not comprehended. Thus, the rise of collaborative consumption offers potential to reduce the greenhouse gas emissions of solo dwellers, and compensate for the lower infra-household sharing with inter-household sharing.
