    Introduction

    The rapid adoption of telework, accelerated by advancements in ICT and the COVID-19 pandemic, offers potential benefits for wellbeing and environmental impact. However, telework’s effects on work productivity, work-life balance, and social connectedness remain complex, particularly within hybrid models combining work-from-home (WFH) and in office days.

    Methods

    This study assessed telework’s impact by comparing WFH and office days. A survey of 1,500 full-time workers in Japan’s Tokyo Metropolitan Region focused on daily time allocation, and telework preferences during telework periods. Principal component and cluster analyses were used to identify groups with distinct work and lifestyle patterns.

    Results

    Six telework-related groups emerged, reflecting diverse experiences in productivity and daily life. Groups such as the “Overall Increase” and “Housework and Rest Increase” reported gains in leisure and family time, positively impacting wellbeing. In contrast, the “Unsuitable for WFH” group faced increased office-day workloads and reduced WFH productivity, indicating that telework’s effectiveness depends on job and individual characteristics.

    Conclusion

    The findings highlight telework’s potential to enhance wellbeing and sustainability but also underscore the need for tailored policies that address diverse job requirements and personal characteristics. This study contributes to sustainable telework strategies by offering insights into effective support systems that balance flexibility, productivity, and environmental sustainability, aiming both for an enhanced personal life and societal benefits.

    Individual behaviors of citizens are important for implementing the necessary measures for adapting to climate change. However, studies on the adaptive behaviors of ordinary citizens are limited. Therefore, in this study, we developed behavioral models to understand individual behaviors for adaption to and mitigation of climate change. We compared four behavior groups, namely, G1, individual mitigation; G2, individual adaptive; G3, long-term adaptive; and G4, solar-energy system installation behaviors. Following a questionnaire survey for the four behavioral groups, behavioral models were developed using structural equation modeling, which considered psychological factors along with selected attitudes, perceived effectiveness, norms, benefits, practicality, and intention. Furthermore, we considered the recognition and attribution of local climate change as key factors for adaptation behaviors toward local climate change. The behaviors of citizens in four prefectures in Japan, namely, Nagano, Tokyo, Saitama, and Kanagawa were considered. Among them, Nagano Prefecture, wherein the implementation of adaptation measures was at a low level while that of mitigation measures was at a high level, showed a differing trend. In the behavioral models, the recognition of local climate change directly affected the behavior of citizens in the individual adaptive behavior group. In both the individual adaptive and long-term adaptive behavior groups, the impact of benefits was substantial, with significant differences across local areas. Thus, effective adaptation strategies might involve tangible and familiar examples demonstrating the consequences of behavior, thus enhancing citizens' behavior evaluation perception and fostering its acceptance as a desirable behavior. Tailoring adaptation strategies to specific local contexts might also be necessity. To encourage citizens to adapt to climate change and its impacts, we propose two-way efforts, instead of providing one-way information, by supporting citizens to think about self-help and mutual help effectively. Our study can serve as a reference for future studies focusing on citizen behavior about climate change mitigation and enhance their adaptation for locally implemented strategies.

    A questionnaire survey was conducted on changes in work and commuting conditions in the COVID-19 situation were surveyed with respect to teleworking, which is expected to reduce environmental impact. Respondents with telework experience in 2020 were sampled in Tokyo, which is highly rail-dependent area, and in Tochigi, which is highly car-dependent area.

    Even during the period of maximum telework, there were few teleworkers who completely teleworked from home or used satellite offices, and many teleworkers worked in combining office work and home. The trend of continuous teleworkers in Tokyo was that many of them were in their 40 s, worked in the information and telecommunications industry, and had a long commuting time. Furthermore, a high percentage of them rearranged furniture or purchased new furniture for telecommuting. On the other hand, women and those in the education industry were the most frequent users only during the emergency declaration period.

    In Tochigi, where the environmental burden of commuting is high due mainly to the use of automobiles, the frequency of commuting to work was high during telework period and the environmental burden associated with commuting resumed as well, as the employees returned to their traditional work style in November 2020 when the COVID-19 disaster subsided somewhat.

    <p>  In this study, a survey residents living in Saitama, Tokyo, Kanagawa, and Nagano prefectures was conducted to deepen the knowledge required to develop educational programs on climate change mitigation and adaptation. The results are as follows: 1) The residents are becoming increasingly aware of the effects of climate change, and this awareness affects not only their adaptation behavior, but also their mitigation behavior. 2) Sufficient recognition of the causes of climate change affects mitigation behavior. An awareness of the effects of climate change on one's personal life affects current responses, and an awareness of the effects of climate change on regions affects long-term responses. 3) Regarding environmental consciousness, the perception to give priority to an action affects current responses, and respect towards nature affects both current responses and long-term responses. 4) Females, especially over 30 years of age, have a strong consciousness of giving priority to an action and have a strong awareness of the effects of climate change. Consequently, their behavior towards adaptation and mitigation is stronger.</p><p>  Based on these results, we consider implementing educational programs on climate change adaptation and mitigation. In particular, consideration is given to developing educational programs for females who are more sensitive to climate change.</p>

  • EXPLORING DETERMINANTS AND MODELS OF CITIZEN'S ENVIRONMENTAL BEAVIORS Reviewed

    Many psychological factors for environmental behaviors (EBs) have been reported, while those specific to each EB are little known. Modeling research aims to make a simple and general model to extract the core psychological structure common to many of the EBs. The simplicity, however, becomes big disadvantage for making actual countermeasures for specific behaviors. Psychological factors should be different for different behaviors. Therefore, for taking an actual step to promote the EBs, it is necessary to make more elaborate and suitable model for each EB. We conducted structural equation modeling exploratively with various variables. The data were gained through the on-line questionnaire survey conducted in Tokyo, Japan. 13 EBs, like &#039;Turning off the light frequently&#039; were picked up (n=350 for each).&lt;br&gt; The constructed model consisted of two parts. The factors on general EBs were merged and appeared as a first step, and as a second step, the each factor on the target EB appeared independently with stronger effect on the intention and the behavior. The number of factors involved in the model ranged from 10 to 16 depending on the EBs. The influential factors were &#039;attitudes&#039; (0.61-0.98 as total effect) for the intensions and &#039;Habits&#039; (0.73-0.93 as total effect) for the behaviors.

    Citizens&#039; pro-environmental behaviors were surveyed in 47 prefectures in Japan. The degree of practice of 44 everyday behaviors and implementation of 13 equipments were surveyed. On the other hand, 25 socioeconomic factors from the local-level statistics were chosen. A regression analysis between the pro-environmental behaviors and socioeconomical factors showed that the personal factors, especially the psychological ones, have more influence than socioeconomic factors on the practice degrees of these environmental behaviors. Subsidy policy of local government was effective to reduce plastic shopping bag use, but the effects of other subsidy were not obvious.
