A perspective on the role of uncertainty in sustainability science and engineering

Greening aviation in era of COVID-19: Towards conceptualizing and operationalizing decarbonization

Although net-zero greenhouse gas emission targets continue to gather burgeoning streams of research, there is a lacuna in current literature on the pathway challenges towards operationalizing decarbonization. The study advanced 2 × 2 matrix of an organizing framework of challenges in accomplishing net-zero emissions targets. Using the global airline industry as an illustrative context, the study provided deep insights on the pivotal industry, institutional, and organizational challenges in the era of COVID-19 such as fleet modernization, over-reliance on fossil fuel, slow progress in the development of hydrogen and electric aircraft, risk of corporate greenwashing, and divergent approaches adopted by airlines. The challenges can be classified into policy-oriented, organization-specific, and external/macro-environment factors. The contributions to theory and practices were identified and examined.

Exploring Social Sustainability Handprint—Part 2: Sustainable Development and Sustainability

Social sustainability is a major part of both sustainable development and sustainability including societal sustainability and overall promotion of more sustainable societies taking into account multiple social/society–environment relationships and interfaces. These contexts have a strong focus on both present and future generations, encompassing sustainable development of both people and the planet. Social sustainability handprints provide many opportunities to promote social sustainability management and assessment by organizations and people and to create changes and encourage actions that contribute to overall social and societal sustainability. This study applied qualitative approaches to explore social sustainability handprints from the perspectives of sustainable development, sustainability, social and societal sustainability and sustainability assessment and indicators. This study addressed a clear research gap and aimed at identifying key definitions, elements, approaches and development focus areas within these frameworks as well as at suggesting associated implications for social sustainability handprint development. The findings suggest that social sustainability handprints can be created through multiple actions, changes, innovations and impacts to promote social sustainability based on sustainable development, sustainability and social and societal sustainability. Various actors such as all types of organizations, individuals, groups and companies can implement these ways to create social sustainability handprints. In addition, there are multiple assessment approaches that can be applied to the assessment of social sustainability handprints such as sustainability management, assessment and indicators, encompassing multiple specific elements and approaches.
