Abstract. The construction sector, a major contributor to global greenhouse gas emissions, offers considerable potential for climate change mitigation through the substitution of traditional building materials with timber. While engineered wood products like cross-laminated timber and glulam have gained attention for structural applications, the use of lower-grade wood and industrial residues for durable, non-structural construction elements remain underexplored.

Abstract. There is a vast literature on the effect of inequality on trust, establishing that equality must be a pre-condition for the emergence of trust. However, most empirical research either focuses on case studies or uses measures of income inequality, such as the Gini index. In this article, we argue that a measure of inequality of opportunities is preferable to focusing on inequality of outcomes, as it taps into the psychological foundations of trust.
