Since Western lifestyles can foster obesity and other problems, attention is turning to active travel (AT) as a means of increasing physical activity for both adults and children. Children's routines regularly focus on trips to and from school which can admit walking and other AT. Yet promoting such an approach encounters a problem around the relative influence on AT of urban form and family decision making. To address it, this study applies the recently-constructed Model of Children's Active Travel (M-CAT). Via its formulations, two field sites in Queensland, Australia, were selected based on objective physical characteristics, determined as supportive and not supportive of children's AT. Parents of 206 children aged 9 to 12 years were surveyed. While 43% reported that their children used AT, a significant difference was observed among children dwelling in areas identified as having high as opposed to low support. Behind this clear result, objective attributes of the physical environment, parents' perceptions and evaluations of urban form and child and family characteristics link in intricate ways to determine children's level of engagement. The inquiry argues for an interdisciplinary approach involving urban designers, planners and health care professionals to address a complex physical and social interaction.

Heavy industry can face challenges in choosing applicable climate change mitigation measures due to a lack of technical background and practical guidance. A better understanding of these determinants is needed to design region-specific climate policies that most effectively enable more ‘successful’ low carbon transitions. Set in an emerging economy, this study aims to understand the determinants which underlie investment decision-making in greenhouse gas reduction. It relies on empirical research using an exploratory case study method in the leading cement company in Indonesia. The results show four key determinants influencing (constraining) adoption were (1) the primacy of profit-seeking objectives in operational planning and development; (2) the availability of sources (clinker substitutes and alternative energy fuels); (3) the limited access to cash capital; and (4) the complexity in implementing emissions reduction projects. The inquiry also compares determinants in an emerging and developed country to provide a comparative perspective on emissions management in manufacturing. It appears that firms from the industrial sector in emerging economies have investment strategies that are largely characterised by activities that accentuate achieving financial benefits or best value for money or cost savings in a short time frame, or ‘short-termism’. Currently, greenhouse gas emissions management activities tend to be second-preference strategies for firms in emerging economies, at least in the industrial manufacturing sector.

There is mounting evidence that, unless greenhouse gas (GHG) emissions fall back quickly, the goals outlined by the 2015 Paris Agreement to keep the global temperature rise well below 2 °C and preferably 1.5 °C will not be met. In response to these concerns, direct air carbon capture and storage (DACCS) technologies are gaining research and development attention. This article provides a thorough comparison of the two leading DACCS variants and reports on their status among major research and policy institutions worldwide. By translating the operating and capital costs to the Australian context, we assess the viability of DACCS implementation using either cheap renewable or legacy fossil energy to power CO₂ extraction plants.
