A time-use approach: high subjective wellbeing, low carbon leisure

The driving factors behind urban communities' carbon emissions in the selected urban villages of Jakarta, Indonesia

As there is a high number of urban communities and residential activities like electricity uses, transportation, food consumption, garbage production, and knowledge on climate change and carbon emissions, these affect the resulting carbon emissions in the city. However, the studies learn about the association between household and human activities, socio-demographic characteristic, carbon emissions and climate change knowledge on urban communities carbon emissions at Jakarta are still rare. This study aimed to assess whether daily human behavior, demographic variables, climate change knowledge, and carbon emissions knowledge affecting carbon emissions of urban communities. A cross-sectional study design was performed via a structured questionnaire survey and a jejakkarbonku application towards 200 respondents who were living in the two selected urban villages of Jakarta, Indonesia (Jatinegara and East Cengkareng). The results revealed that the mean urban communities' carbon emissions in the region were 4.4 tonnes CO2 eq/th. Electricity consumption in the kitchen and dining room produced the most carbon emissions (38.6%), and waste disposal activity produced the least (0.68%). Urban carbon emissions affected by employment status and income level, but not according to food consumption, garbage production, climate change and carbon emission knowledge. Climate change and carbon emissions knowledge influenced by marital and employment status. Although not significant, in theory, these two types of knowledge contribute indirectly to carbon emissions. Further research on the low carbon diet, intervention studies to increase deep awareness on the carbon emissions and climate change is needed to develop strategies reducing carbon emissions at urban communities.

Estimating the carbon footprint of household activities in Japan from the time-use perspective

The household sector is a major driver of energy consumption and greenhouse gas (GHG) emissions. However, most existing studies have only estimated households' carbon footprint from their expenditures. Households' daily activity time, a scarce resource that limits and determines their consumption behavior, has rarely been integrated into the estimation. Incorporating the daily time-use patterns should thus provide a more practical perspective for mitigation policies aiming at promoting sustainable household lifestyles. In this study, by linking household time-use data and expenditure data of Japan, the carbon footprint and the GHG intensity of time of 85 daily household activities constituting the 24 hours in a day are estimated. Compared to the maximal 20-activity disaggregation in existing studies, our detailed 85-category disaggregation of daily time enables unprecedented details on the discrepancies between the carbon footprint from daily activities, many of which have previous been treated as one activity. Results indicate significant carbon mitigation potential in activities with a high GHG intensity of time, such as cooking, bathing, and mobility-related and activities. Average daily GHG emissions were also found to be higher on weekends as time-use patterns shift from paid work to free-time activities, highlighting the need for mitigation strategies on a weekly scale.

Transformative low-carbon urban innovations: Operationalizing transformative capacity for urban planning

Cities can set in motion sustainability transitions through experimentation and innovation. To invest in and mainstream solutions that contribute to urban transformation agendas, urban planners needs to understand which innovations have transformational potential as well as how these innovations can accelerate sustainability transitions. In order to explore this, existing frameworks of transformative capacity provide the guidance, but they are generic, abstract, and challenging to apply for urban planning. As part of our effort to develop a more operational version of the transformative capacity framework by Wolfram (2016), we conducted a systematic scoping review of the academic literature to determine the characteristics of people-based and nature-based low-carbon innovations that constitutes their transformative capacity. After reviewing 65 records, we identified dimensions indicating each of the transformative capacity components through analysis and synthesis. Besides contributing to the science-policy interface through a knowledge synthesis on low-carbon people-based and nature-based innovations, this paper examines bridging frameworks to inform urban planners in developing practical solutions and actionable elements for low-carbon urban futures.

The Catalogue of Leisure Activities: A New Structured Values and Content Based Instrument for Leisure Research Usable for Social Development and Community Planning

Leisure is a phenomenon that undergoes constant change. These changes are sometimes global, but more often, they are localized. For this reason, the capturing of leisure and leisure activities poses a major challenge for researchers. In particular, they struggle to capture measurements for leisure activities in such a way that these measurement results can be compared over time, in different places, and in different communities. We have therefore identified the need for a tool that makes it possible to compare both time- and place-specific measurements. Based on our long-term research, we have created the Catalogue of Leisure Activities (CaLA), which is built on two pillars—content proximity and value consequences of leisure activities. Therefore, the CaLA allows for the capturing of the complexity of leisure activities and using the data thus measured as variables in statistical hypotheses, longitudinal comparisons of research across locations, over time, and across population groups (e.g., children, adults, etc.). It also allows measurements of other secondary characteristics (e.g., favor rate, duration, etc.) to be linked to the activities found. The results of measuring leisure activities using the CaLA can be used in research as a dependent or independent variable. As a result, we can detect many hitherto hidden relationships that significantly influence leisure experience and its quality. The CaLA also opens up many more possibilities for a wider range of applications in practice, e.g., in counseling, psychology, and coaching in support of individual development, in helping professions, social work and pedagogy when working with students and clients, and among managers when planning the development and maintaining the competitiveness of leisure facilities. Last but not least, the CaLA can be used by community leaders and politicians when designing public policies or developing a sustainable society.
