Mitigating climate change to achieve the goal of staying below 2 °C of warming requires urgent reductions of emissions. Demand-side measures mostly focus on the footprints of consumption. Analysing time use can add to understand the carbon implications of everyday life and the potentials and limitations for decarbonising consumption better. We investigate the carbon footprints of everyday activities in Austria. We linked data from the Austrian Time-use Survey and the Austrian Household Budget Survey with the Eora-MRIO for 2009–2010 in order to estimate the household carbon footprints of all time-use activities. We introduce a functional time-use perspective differentiating personal, committed, contracted and free time to investigate the average carbon intensity of activities per hour, for an average day and for the average woman and man. We find that personal time is relatively low-carbon, while household as well as leisure activities show large variation in terms of CO2e footprint/h. The traditional gendered division of labour shapes the time-use patterns of women and men, with implications for their carbon footprints. Further research analysing differences in household size, income, location and availability of infrastructure in their relation to time use is crucial to be able to assess possible pathways towards low carbon everyday life.

时间很重要：奥地利日常活动的碳足迹

减缓气候变化以实现将升温幅度控制在 2°C 以下的目标需要紧急减排。需求侧措施主要关注消费足迹。分析时间使用有助于了解日常生活对碳的影响以及更好地脱碳消费的潜力和局限性。我们调查了奥地利日常活动的碳足迹。我们将 2009-2010 年奥地利时间使用调查和奥地利家庭预算调查的数据与 Eora-MRIO 相关联，以估计所有时间使用活动的家庭碳足迹。我们引入了一个功能性时间使用视角，区分个人时间、承诺时间、合同时间和空闲时间，以调查每小时活动的平均碳强度，平均一天，平均女性和男性。我们发现个人时间相对低碳，而家庭和休闲活动在二氧化碳排放量/小时方面表现出很大的差异。传统的性别分工塑造了女性和男性的时间使用模式，影响了他们的碳足迹。进一步研究分析家庭规模、收入、位置和基础设施可用性与时间使用相关的差异对于评估实现低碳日常生活的可能途径至关重要。
