Public regulations can result in improved environmental performance of products. In this paper eco-efficiency is used to assess the most likely outcome of potential new regulations. The paper presents a case study of furniture production in Norway where different scenarios for improving the environmental performance of the products are presented. Four regulatory options for imposing environmental improvements are assessed; (1) an introduction of a tax on emissions, (2) an increase of the tax on landfills, (3) an introduction of a tax on raw material consumption, and (4) introduction of take-back legislation. ; This is an open access article distributed under the Creative Commons Attribution License (CC BY) which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited.
Purpose The purpose of this study is to understand how to improve the recognition of biodiversity knowledge for engineering students, using a case study in the context of Norway.
Design/methodology/approach A case study based on an elective course for engineering students was carried out. The course is related to sustainability and also explicitly focuses on biodiversity topics and causality for loss of biodiversity. Data was collected through questionnaires to students to understand their motivations and perceptions about the course, and through interviews with study programme coordinators, to understand their perspectives regarding sustainability and biodiversity education for engineering programmes.
Findings Three main conclusions are established: the best approach is to incorporate biodiversity content into existing courses, rather than having a specific course dedicated to biodiversity; more knowledge on biodiversity is seemingly increasing the understanding of its importance, thus, students should be exposed to these topics early in their studies; and some strategies to improve the current course are related to being more specific on how to deal with biodiversity in different contexts (such as working life and different industries), offering a higher number of examples, and linking biodiversity with other environmental impacts.
Originality/value To the best of the authors' knowledge, this study is the first to address the recognition of biodiversity knowledge in engineering programmes at a Norwegian university. The case study provides valuable insights that can be used to improve the integration of biodiversity knowledge into engineering programmes. Moreover, the methods used provide innovative and more reliable tools to better address the perceptions of stakeholders.
The construction sector is progressively becoming more circular by reducing waste, re-using building materials and adopting regenerative solutions for energy production and biodiversity protection. The implications of circularity on construction activities are complex and require the careful evaluation of impacts to select the appropriate path forward. Evaluations of circular solutions and their environmental efectiveness are often performed based on various types of life cycle-based impact assessments. This paper uses systemic thinking to map and evaluate diferent impact assessment methodologies and their implications for a shift to more circular solutions. The following systemic levels are used to group the methodologies: product (material life cycle declarations and building assessments), organisation (certifcation and management schemes) and system (policies, standards and regulations). The results confrm that circular economy is integrated at all levels. However, development and structure are not coordinated or governed unidirectionally, but rather occur simultaneously at diferent levels. This recursive structure is positive if the methods are applied in the correct context, thus providing both autonomy and cohesion in decision making. Methods at lower systemic levels may then improve production processes and stimulate the market to create circular and innovative building solutions, whereas methods at higher systemic levels can be used, for example, by real estate builders, trade organisations and governments to create incentives for circular development and innovation in a broader perspective. Use of the performance methods correctly within an actor network is therefore crucial for successful and efective implementation of circular economy in the construction sector. ; publishedVersion
