  Abstract European legislation continuously increases requirements for carbon footprint accounting for buildings. The energy efficiency and embodied carbon of buildings are regulated through the energy efficiency directive with targets for 2030. While construction production regulation makes it mandatory to disclose carbon footprints of key materials such as insulation by 2027. Improving building products to lower their embodied CO2 emissions and to include additional carbon storage capabilities is seen as one of the most promising ways to mitigate the climate impact of the construction sector. Technological advancements and increased use of bio-based materials are vital. However, strategies to prolong the lifespan and maximize effective carbon storage of these materials are equally important. This paper aims to explore trends in the development of new bio-based materials (with focus on insulation materials) as alternatives to existing building materials supporting the global shift towards carbon neutrality. The study objectives are to investigate and map the main areas and types of new bio-based building materials, with equal interest in strategies for reuse and recycling to extend stored carbon and reduce emissions. The results show that bio-based material could have additional benefits of energy storage, carbon sink and recycling at end-of-life. However, most assessments of these materials focus on a narrow cradle-to-gate scope and thermal conductivity as only insulation material property. Hence, to further advance on bio-based insulation materials, there is a need for further development and harmonization of life cycle assessment methods that include these aspects and can be implemented in standards and regulations.

  Product-service systems (PSS) where business combines goods and services presents a promising approach to reduce environmental impacts while still providing economic prosperity. PSS has been assessed for more than 20 years, but there is still a need for empirical evidence of the effects and development of applicable assessment methodologies based on life cycle assessment (LCA). This paper presents a novel approach to address environmental performance of PSS through life cycle based eco-efficiency that can be consistently benchmarked with macro level data. The approach was based on a method developed for assessing new business models with LCA and includes a case study for a rental company with power tools and hardware equipment. The results show that from a user perspective, the environmental benefit of renting a product depends on number of uses that is needed and transport distance, but also the weight of the product. The heavier and more expensive products are more beneficial when it comes to costs, carbon footprint and resource use. From a PSS business management perspective, two approaches were compared. First a consequential LCA approach where rental substitutes ownership and second the novel approach with eco-efficiency decoupling indicators. The consequential approach favours heavier products, and the business is dominated by a few products. For the eco-efficiency approach, the potential revenue is more important than weight. The eco-efficiency approach to LCA for PSS showed advantages to consequential LCA approach as it requires less user behaviour data and can be benchmarked with decoupling needed with the planetary boundaries framework.

  This study explores the emergence of a distinctive learning-community aspect of teaching sustainability. It uses action nets to describe major contributions shaping a learning community about sustainability. The results describe how the growing learning community of research, externally funded projects, teaching strategies, students, NGOs, and regional industry is framed within a sociotechnical network of actants and identifies events exposing the transitions in the making. Based on the findings, we discuss lessons learned from the co-creation, increasing the awareness of mechanisms involved in gaining (and regaining) support needed to create the new approach to teaching sustainability. The learning community mirrors, in many ways, the systemic nature of sustainability and sustainable development. It also introduces the uncertainty and ambiguity inherent in the transitions. It was easier than anticipated to mobilize resources, but the connections between the different contributions are also delicate, and we experience the learning community as something like fresh produce—something we must create and recreate continuously.

  FutureBuilt is a voluntary program for ambitious low-carbon construction projects. To incentivize measures that lead to the lowest climate change impact from all aspects of buildings and according to national Paris agreement pledges, FutureBuilt Zero introduces an ambition level and a novel calculation methodology for net climate change impacts over the life of a building. The ambition level is tightened over time to help Norway achieve its climate goals. A comprehensive simplified calculation method is introduced, which considers how the timing of emissions during the building life affects the contribution to global warming. Both direct and indirect emissions throughout the lifetime are included; energy use in operation and at the construction site, material production and transport of materials to the construction site, and waste management (incineration). In addition, the climate-positive effects of biogenic carbon uptake, carbonation of cement, potential for future reusability, and exported energy are included. This paper presents the criteria, describes the method and the scientific basis as well as the principles and logic behind the choices made.

  Carbon footprint over the life cycle is one of the most common environmental performance indicators. In recent years, several wood material producers have published environmental product declarations (EPDs) according to the EN 15804, which makes it possible to compare the carbon footprint of product alternatives. The objective of this study was to investigate the effect of service life aspects by comparing the carbon footprint of treated wood decking products with similar performance expectations. The results showed that the modified wood products had substantially larger carbon footprints during manufacturing than preservative-treated decking materials. Replacement of modified wood during service life creates a huge impact on life cycle carbon footprint, while maintenance with oil provided a large contribution for preservative-treated decking. Hence, service life and maintenance intervals are crucial for the performance ranking between products. The methodological issues to be aware of are: how the functional unit specifies the key performance requirements for the installed product, and whether full replacement is the best modeling option in cases where the decking installation is close to the end of the required service life.

  The forest and building sector is of major importance in climate change mitigation and therefore construction materials based on forest products are of great interest. While energy efficiency has had a large focus in climate change mitigation in the building sector, the carbon footprint of the construction material is gaining relevance. The carbon footprint of construction materials can vary greatly from one type to another, the building sector is consequently demanding documentation of the carbon footprint of the materials used. Using an environmental product declaration (EPD) is an objective and standardised solution for communicating the environmental impacts of construction products and especially their carbon footprint. Nevertheless, it is challenging to include the features of forest products as pools of carbon dioxide. There is currently a focus on research into methods for the accounting of sequestered atmospheric carbon dioxide and also implementation of these methods into technical standards. This paper reviews the recent research and technical standards in this field to promote a common understanding and to propose requirements for additional information to be included in EPDs of forest-based products. The main findings show the need for reporting the contribution of biogenic carbon to the total on greenhouse gas emissions and removals over the product’s lifecycle. In order to facilitate the implementation of more advanced methods from research, the EPD should also include more detailed information of the wood used, in particular species and origin.

  Novel bio-based construction materials and phase-change materials (PCMs) have attracted increasing attention due to their potential to reduce operational energy demand and improve building sustainability, and the potential to enlarge anthropogenic carbon sinks (Livne et al., 2022, Hawkins et al., 2023). However, current studies mainly assess their environmental performance through conventional life cycle assessment (LCA) based on laboratory-scale data. This approach has important limitations and may overlook environmental impacts associated with full-scale production (Alaux et al., 2024, Sacchi et al., 2022). To address this gap, this study applies a prospective, ex-ante LCA framework to evaluate the environmental performance of a novel bio-based composite.

  In the past 12 years, more than 50 FutureBuilt pilot projects have shown that it is possible to reduce greenhouse gas emission from transport, energy and materials for the built environment. The FutureBuilt programme supports climate friendly urban development in Norway’s capitol city Oslo and surrounding municipalities (Bærum, Asker, Drammen, Nordre Follo and Lillestrøm). All projects have until now been required to perform carbon footprint calculations and to reduce emissions by 50% compared to a reference common practice. Followng the political ambitions to further reduce greenhouse gas emissions, the FutureBuilt criteria has been updated to reflect these, with the development of a scheme called FutureBuilt ZERO. The FutureBuilt ZERO method is based on the Norwegian standard for carbon footprint calculations of buildings (NS 3720), but has taken a more forward looking approach. The method is taking into account expected future developments in society related to carbon footprint aspects that has often been left out in common carbon footprint practice. It includes contributions to greenhouse gas emission of direct and indirect emissions from operational energy, manufacturing, and transport of materials, related to building construction, operation, maintenance and end-of-life. In common carbon footprint of buildings, scenarios for maintenance and end-of-life of buildings are often assessed based on current practice. However, in the FutureBuilt ZERO method, the changes in technology and policy have been taking into account for adjusting emission factors. Other aspects that are often left out in common practice such as biogenic carbon, time-dependent characterisation factors, carbonatization of concrete, design for reuse and exported energy, are also included. The process to take into account such aspects requires input from several experts and the presentation will bring forward some of the aspects that has been deliberated in the making of the method.

  FutureBuilt ZERO introduserer kriterier for netto klimagassutslipp over hele byggets levetid. Kriteriene strammes gradvis inn over tid for å bidra til at Norge når sine klimamål. FutureBuilt ønsker å best mulig insentivere de valg som vil føre til lavest klimapåvirkning fra de mangfoldige aspektene ved bygninger. Det introduseres derfor en helhetlig metode som tar hensyn til utviklinger i utslipp over tid, og deres bidrag til global oppvarming. Både direkte og indirekte utslipp er med, fra energibruk i drift, fra materialfremstilling og transport av materialer til byggeplass, både under oppføring og for senere utskiftninger av materialer. Det er også med utslipp fra byggeplass, og fra avfallsforbrenning av utskiftinger og ved endt levetid. I tillegg tas effektene fra biogent karbonopptak, fra karbonatiserting av sement, fra tilrettelegging for ombruk, og fra eksportert energi med. I dette dokumentet beskrives metoden, og prinsippene og logikken som ligger bak.

  Torv benyttes i dag som dyrkingsmedium og i jordforbedringsprodukter. Uttak av torv medfører utslipp av klimagasser og påvirker leveområdene til planter og dyr. Ved en eventuell utfasing av torv er det viktig at bruken av andre materialer representerer en reell miljøforbedring. Denne rapporten er skrevet på oppdrag fra Miljødirektoratet, og tar for seg klima- og miljøeffekter av ulike materialer som erstatning for bruk av torv i dyrkingsmedier og jordforbedringsprodukter. Studiet omfatter materialene steinull, perlitt, biprodukter fra kokosproduksjon, bark, trefiber, kompost og avvannet biorest, biokull og ull fra husdyr. Studien ble gjennomført ved hjelp av en litteraturgjennomgang, søk i databaser og noen forenklede beregninger basert på tall funnet i litteraturen for å etterstrebe at resultatene er mest mulig relevante for norske forhold.
