This open access book represents a journey documenting the development of tools and methodologies over 3 decades and asks where the future lies. It further develops seminal work carried out under the auspices of the Capacity building in Sustainability and Environmental Management (CapSEM) project co-funded by the EU Erasmus programme from 2016-2019 as well as research projects such as IGLO-MP2020, SUSPRO, and SISVI. It gathers existing paradigms of environmental management within the relevant frameworks which have driven the way in which this discipline has developed. It seeks to both challenge and support the way in which business sectors have approached this previously, with a more holistic and overarching model being provided, moving through four very distinct levels.  It therefore provides not only a different approach, but a different way of thinking. Systems thinking is characterized by four levels: Process, Product Value Chain, Organisational and Systemic which combinesMaterial Flow Analysis (MFA), Life Cycle Assessment (LCA), Corporate Social Responsibility (CSR) and Industrial Ecology (IE) principles. In its practical application, Corporate Social Responsibility, for example, thus becomes an integral part of a much wider business strategy and impacts on all business activity, not added value for its own sake, but a valuable component in a wider toolbox as a fundamental part of any business strategy and plan, changing, flexing and developing over the years.
The book is divided into 4 parts: moving from context and background, to the theoretical model or toolbox, onto its practical application in case studies and culminates in looking at the future and potential developments. It represents the multi-disciplined collaboration at NTNU and beyond, exemplifying its use in a wealth of business sectors and a range of stakeholders from construction to textiles to wind power as outlined in the European Circular Action Plan.
