Turistindustrin rankas som en av världens största, men även snabbast växande näringar. Näringens expansion bidrar i sin tur till stora miljömässiga konsekvenser. Mer miljövänliga, spårbundna transporter är i dagsläget aktuella forskningsfrågor och diskuteras i syfte att bromsa turismens negativa, miljömässiga effekter. Studiens syfte var att undersöka ungdomars intresse och attityder kring tåg i turistiskt syfte, samt om en antagen miljömedvetenhet påverkade deras val av resa. Interrail valdes som undersökningsobjekt dels då skribenterna fann ämnet aktuellt och dels på grund av EU-kommissionens investering som ska ge 18-åringar gratis Interrailpass i år. Interrail ansågs i enlighet med teorier vara ett alternativt, mer miljövänligt transportalternativ samt turismform. En kombination av kvantitativa och kvalitativa metoder har använts för att besvara studiens syfte och frågeställningar. Enligt valda teorier förekommer ett gap mellan turisters attityder och beteende där personliga värderingar och en miljömedvetennorm, som genomsyrade beteenden och konsumtionsmönster hemma, bortsågs vid val av resa. Resultaten från de sju personliga intervjuerna samt enkätundersökningen tyder på att intresset för tåg som transport i turistiskt syfte är relativt lågt, vilket eventuellt ger en förklaring till det relativt låga intresset för Interrail hos dagens ungdomar. Även bland organisationer tolkas Interrail besitta en låg position på marknaden. Företag är inte intresserade av att marknadsföra Interrail då det inte antas vara vinstdrivande. Intresset för Interrail är lågt där aspekter som tid, pris, bekvämlighet och upplevelse väger tyngre hos ungdomars turistiska val, där tågets miljömässiga fördelar snarare ses som en positiv bieffekt. Utifrån bristande kunskap och förutfattade meningar tolkar skribenterna Interrails comeback, trots EU-kommissionens ekonomiska investeringar, som svåruppnådd. / he tourism industry is ranked as one of the world's biggest and fastest growing industries, which in return contribute to big environmental consequences. More environmentally friendly, railway bound transportation are current research questions and are discussed to prevent the negative effects of tourism. The purpose of the study was to research adolescents interest and attitude towards train for touristic purposes and if their perceived environmental awareness affected their choice of travel. Interrail was chosen as a research object partly because the authors considered it a current topic and partly because of the investment that the EU-commission made to be able to give 18-year olds free Interrailpasses this year. Interrail was in accordance with the theory perceived to be a more environmentally friendly choice of transportation and form of tourism. A combination of qualitative and quantitative methods was used to answer the purpose and questions of the study. From the chosen theories there appears to be a gap between tourists attitudes and behaviour, where personal values and the environmental norm that existed at home, was disregarded when choosing to go on a trip. The results from the 7 personal interviews and the questionnaire shows that the interest for train as transport for touristic purposes is relatively low, which could give an explanation for the lacking interest for Interrail in today's adolescents. Even among companies Interrail is interpreted as having a low position on the market. Companies aren't interested in marketing Interrail due to its low perceived economic profit. The interest for Interrail is low where aspects such as time, price and experience weighs heavier for adolescent’s touristic choices, where the environmental benefits are merely seen as a positive bi-product. From a lack of knowledge and preconceptions the authors interpret Interrails comeback, despite the financial investments from the EU-commission, as hard to achieve.

Les ressources minérales s’épuisent inexorablement, les minerais riches sont de plus en plus difficilement accessibles, et le traitement des minerais implique d’importants impacts environnementaux. En Nouvelle-Calédonie, l’extraction du nickel nécessite la destruction de l’horizon fertile supérieur des sols, et les mines se présentent comme des carrières à ciel ouvert, soumises à l’érosion et menaçant la biodiversité du territoire. Bien que l’exploitation du nickel soit au cœur de l’économie locale, la réhabilitation écologique des sites miniers, et la réintroduction durable d’un couvert végétal sont une nécessité.Le laboratoire ChimEco a démontré qu’il était possible de revégétaliser les sites miniers en réintroduisant des espèces végétales pionnières, résistantes et accumulatrices de manganèse. Ces plantes accumulatrices sont capables d’extraire le manganèse naturellement présent dans le sol et de l’accumuler dans leurs parties aériennes : on parle de phytoextraction. Le laboratoire ChimEco propose en outre une valorisation scientifique et à terme économique des efforts de réhabilitation engagés sur le terrain. En effet, à partir de la biomasse riche en manganèse des plantes accumulatrices, le laboratoire ChimEco a développé un procédé innovant de recyclage des éléments métalliques d’origine végétale en catalyseurs polymétalliques pour la chimie. Il s’agit de l’Ecocatalyse. Ces écocatalyseurs riches en Mn, notés Eco-Mn, ont montré une activité catalytique intéressante dans plusieurs synthèses organiques.Les résultats obtenus en écologie et en chimie par le laboratoire ChimEco prouvent la nécessité d’étudier finement la structure des écocatalyseurs en les considérant comme des matériaux innovants, afin de comprendre et d’améliorer leur activité en synthèse organique, et d’exploiter au mieux les possibilités du procédé. C’est précisément dans ce contexte que s’inscrivent ces travaux de thèse.Plusieurs techniques d’analyse ont été utilisées. Les analyses ICP-MS ont permis de déterminer la composition élémentaire des Eco-Mn. La DRX a permis de mettre en évidence la présence de sels mixtes originaux tels que K3NaMnCl6 sous forme cristalline dans les Eco-Mn. Enfin l’absorption des rayons X a permis de déterminer la nature des espèces présentes dans les catalyseurs, ainsi que le degré d’oxydation du manganèse et du fer. En outre, l’étude du réarrangement d’un acétal cyclique, ainsi que le suivi de la désorption de la pyridine à la surface des Eco-Mn, ont été utilisés pour étudier les propriétés acides des écocatalyseurs. Ces analyses ont permis de répondre à deux objectifs précis : d’une part déterminer la nature des complexes qui composent les Eco-Mn, et d’autre part, mieux comprendre les propriétés physico-chimiques de ces catalyseurs, leur degré d’oxydation et leurs propriétés acides. Ces analyses ont également permis de mieux appréhender les deux étapes du procédé de synthèse des Eco-Mn. Enfin, des catalyseurs synthétiques et témoins ont également été produits et étudiés dans les mêmes conditions d’analyse que les Eco-Mn, dans le but de déterminer si les Eco-Mn ont une spécificité et une empreinte végétale. / Mineral resources are running out, ores are hardly accessible, and ores processing damage the environment. In New-Caledonia, nickel ores mining requires to remove all the upper layers of the ground, leading to open-cast mines subjected to erosion, which threaten the environment and the biodiversity of the archipelago. Although mining ores exploitation is important for the economy of New-Caledonia, the ecological remediation of mining areas through the restoration of a vegetation cover, are necessary.ChimEco laboratory has demonstrated that it is possible to reintroduce pioneering endemic plant species, which are resistant to climate conditions and accumulate manganese, to restore New-Caledonian mining sites. These accumulating plants extract Mn from the ground to their aerial parts: it is called phytoextraction. Besides, ChimEco laboratory puts forward a new scientific and economic valorisation of phytoremediation efforts in New-Caledonia. Indeed, an innovative process has been developed to recycle metallic elements from manganese enriched biomass into innovative and polymetallic catalysts for organic synthesis. This new process is called Ecocatalysis. Ecocatalysts enriched in manganese, Eco-Mn, have demonstrated interesting and promising catalytic activities in several reactions.Regarding the good results achieved by ChimEco in ecology and in chemistry with accumulating plants and resulting Eco-Mn, it is necessary to better and precisely characterise Eco-Mn catalysts, by considering them as innovative materials, in order to understand and foresee their catalytic activity. This PhD work belongs within this context.Several analyses have been performed to characterise Eco-Mn catalysts. First, ICP-MS enables to identify metallic composition of Eco-Mn. Besides, XRD analyses highlight the presence of complex crystallized manganese salts, like K3NaMnCl6. Finally, X-ray absorption spectroscopy enables us to study the nature of manganese species which compose Eco-Mn catalysts, and to understand the oxidation states of Mn and Fe. Moreover, acid properties of Eco-Mn were demonstrated thanks to the study of a cyclic acetal rearrangement and infra-red spectroscopy of adsorbed pyridine. All these analyses were performed in order to determine first the composition of Eco-Mn catalysts, and secondly to highlight their physico-chemical properties, their oxidation state and their acid properties. Furthermore, this study also enable us to better understand the different steps of the ecocatalysts production process. Finally, synthetic catalysts were also produced and analysed in the same conditions as Eco-Mn, in order to bring out the specificities of Eco-Mn.

This research investigated how TBF s of São Carlos/SP have involved in environmental sustainability. It focuses on environmentally friendly strategies employed by companies in sectors that are likely to be environmentally impactful. The survey verifies the environmental performance of firms by identifying if companies have done effective actions, and investigates whether they have proactive, preventive or reactive attitudes in response to pressure from legislation, environmental certification or public pressure. This research characterized those companies considering, among other factors, their relationship with local universities and research centers, characterized the entrepreneurs and verified if environmental certification is usual with the TBF s. This research is supported by work previously done on TBF s and manuals and norms, among other sources. Data were collected by means of questionnaire sent to 10 companies from industrial sectors whose production processes potentially impact the environment. It was possible to draw a partial picture of the environmentally friendly strategies employed, verify the low certification of ISO 14001 and the need for incorporating more effective environmentally friendly practices by those companies. Entrepreneurs of the companies investigated have a high educational level, and the employees have an educational level higher than those usually observed in traditional types of businesses. Most of the founders of the companies investigated come from educational and research institutions of São Carlos which also influence the technological areas developed by the companies. / Há uma expectativa das empresas de base tecnológica (EBTs) se adequarem com maior facilidade às mudanças exigidas pelo mercado por serem empresas tecnologicamente dinâmicas, por serem mais flexíveis devido ao porte e por possuírem bases intensas de conhecimento. Esta pesquisa investigou como EBTs de São Carlos/SP vêm se relacionando com a sustentabilidade ambiental. A pesquisa se concentra nas estratégias ambientais adotadas por empresas de setores provavelmente impactantes ambientalmente. A pesquisa averigua o comportamento ambiental das empresas identificando se as empresas apresentam ações efetivas, e investigando se apresentam posturas proativas; preventivas ou reativas como resposta a pressões de legislação, certificação ambiental ou da pressão pública. A pesquisa caracterizou estas empresas considerando, entre outros fatores, sua relação com as universidades e centros de pesquisa locais, caracterizou os empreendedores e verificou se são empresas que tem como característica adotar certificado ambiental. Esta investigação se apóia em trabalhos previamente realizados sobre as EBTs e em manuais e normas, entre outras fontes. Os dados foram coletados por meio de questionário enviado a 10 empresas de setores industriais cujos processos produtivos potencialmente impactam ambientalmente. Foi possível traçar um panorama parcial sobre as estratégias ambientais adotadas, verificar a baixa adoção da ISO 14001 e a necessidade da incorporação de práticas ambientais mais efetivas por estas empresas. Os empreendedores do grupo de empresas investigado apresentam um alto nível educacional, e os funcionários possuem um nível de capacitação superior ao que geralmente é observado em empresas do tipo tradicional. Grande parte dos fundadores das empresas investigadas é proveniente das instituições de ensino e pesquisa de São Carlos além destas influenciarem as áreas tecnológicas de atuação das empresas.

Att vara lönsam är en förutsättning för företags långsiktiga överlevnad. Samtidigt blir det generellt sett allt hårdare konkurrens och antalet konkurrenter ökar ständigt. Företag behöver således hitta sätt för att kunna fortsätta vara konkurrenskraftiga på marknaden. Enligt resursbaserad teori kan företag inneha eller skapa resurser inom sin verksamhet som kan leda till varaktiga konkurrensfördelar, och som följaktligen är viktiga att identifiera och utnyttja på bästa sätt. En tillfällig konkurrensfördel anses vara värdefull, ovanlig samt icke utbytbar. För att resursen ska kunna anses vara varaktig ska den inte heller gå att imitera av konkurrenter. I denna rapport ligger fokus på hur företag inom dagligvaruhandeln försöker skapa varaktiga konkurrensfördelar genom arbetet med miljövänliga förpackningar. Miljövänliga förpackningar utgör en betydande del av branschens miljöpåverkan då dessa kännetecknas av hög omsättning och snabb förbrukning. Idag utgör egna varumärken allt större del av omsättningen bland företagen. Dessa varumärken har företagen självklart en betydande möjlighet att påverka, bland annat produktens egenskaper och inte minst dess förpackning. Denna studie bygger på intervjuer med respondenter från tre företag inom dagligvaruhandeln med varierande marknadsandelar. Studien visar att företagen arbetar med miljövänlig förpackningsutveckling på många sätt. Rapporten redogör för hur företagen arbetar för att effektivisera förpackningskedjan, utveckla förpackningar som minskar matsvinn samt hur samarbeten mellan förpackningskedjans användare ser ut och dess betydelse. Det diskuteras även huruvida åtgärderna syftar till att utveckla varaktiga konkurrensfördelar eller ej. Det beskrivs även hur företagen kommunicerar sitt arbete med miljövänliga förpackningar samt hur de strävar efter att utveckla förpackningsinnovationer.

Handel via internet har vuxit i rekordfart vilket har lett till fler hemleveranser och därmed fler transporter. Samtidigt ökar behovet av att minska konsumtionens klimatpåverkan. Symboler har varit ett frekvent använt verktyg för att förmedla produkters miljöpåverkan. Hur konsumenter anser att transportens miljöpåverkan sak kommuniceras är ännu ett outforskat område. Syftet med studien är att undersöka hur e-handelskonsumenter anser att kommunikation av miljövänligare transport bör utformas för att det miljövänligare alternativet ska framstå som mer attraktivt. Vidare vill vi undersöka om det finns skillnader och likheter i frågan mellan konsumenter med olika karaktärsdrag och i sådana fall vilka skillnader och likheter. Denna kvantitativa studie antar en deduktiv ansats där undersökningen utformas med tidigare forskning som bakgrund. En tvärsnittsdesign ligger till grund för det empiriska materialet och urvalet är e-handelskonsumenter av dagligvaror. Studiens resultat visar att enligt konsumenterna ska kommunikationen av miljövänligare transport bestå av formatet symbol och informationen ska ta hänsyn till att de motiveras mest av att göra gott för omvärlden och miljön, att ta eget ansvar samt att förstå konsekvenserna av sina val. Det största hindret enligt konsumenterna är pris. Vidare upptäcktes vissa samband mellan konsumenternas karaktärsdrag och vilken kommunikation de anser gör den miljövänligare transporten mer attraktiv. / Introduction Online shopping has grown rapidly which has led to an increased home delivery transportation. At the same time, the importance of decreasing the climate impact from consumption is a fact. Symbols have been a popular tool to communicate the environmental impact of products. The consumers’ opinions regarding how the communication of environmentally friendly transports should be made, is still an unexplored area. Purpose The purpose of the study is to investigate how e-commerce consumers consider that communication of environmentally friendly transportation should be designed to make that option more attractive. Furthermore, we want to investigate whether there may be differences and similarities between consumers with different characteristics and, in such cases, which those are. Method This quantitative study has a deductive approach and the survey was designed upon a foundation of previous research. The empirical material consists of a survey where the selection was ecommerce consumers of groceries. Conclusion This study’s results show that, according to the consumers, communication of environmentally friendly transportation should consist of the format symbol and the information should consider that they are mostly motivated by doing good for their surrounding world, acting responsibly and understanding the consequences of their action. The largest obstacle for the consumers is the price. Furthermore, some relationships were identified between consumer characteristics and what type of communication they consider makes more environmentally friendly transport attractive.

Products make substantial impact on environment. Design for Environment (DfE) is an approach to design where all the environmental impacts of a product are considered over entire products life. Since over 80% of the product costs are committed during the early stages, design can play a central role in reducing this environmental overloading by product. However, unlike cost and performance, use of environmental criteria and DfE is far from part of mainstream designing. Individual guidelines often exist for DfE but these are not integrated with design tools. There is a need for capture of the rationale in design process as a know how backup for later use. Life Cycle Assessment (LCA) is currently the most promising and scientifically proven technique for estimating environmental impacts of a product during its lifecycle. Current LCA tools are not well integrated with design process and CAD tools. Consequently, there is a need for an LCA tool integrated into the natural design process that can be applied to early as well as detailed design stages. Detailed LCA is critically dependent on high volumes of product specific data, time consuming, often unaffordable and used after the detailed stages of design. Current approximate LCA methods are either incomplete, inaccurate or require prior knowledge of what data is important There is substantial uncertainty involved in the environmental impact calculations in LC. While Literature discusses uncertainty of impact data, there is no discussion on how to calculate and represent the total uncertainty in the potential impact of a product proposal at any given stage in design with respect to LCA. There is a need for a method that can aid in decision making by supporting quantitative comparison of available alternatives to identify the best alternative, under uncertain information about alternatives. Often the likely performance, cost or environmental impacts of a product proposal could be estimated only with certain confidence, which may vary from one proposal to another. The overall objective of this thesis is to “Develop a support to the designers using which they can develop environmentally friendly product lifecycles in much the same way as they currently design products, at all stages of their design, while reusing information from their past design activities”. For this the specific objectives are to: 1.Understand how designers currently design products and what they need for developing environmentally friendly product design. 2.Develop a holistic framework for both generation and evaluation of environmentally friendly life cycle proposals. 3. Capture rationale as part of the design process. 4. Estimate uncertainty in the environmental impact assessment during design. 5. Evaluate product lifecycle proposals with multiple criteria under uncertainty. 6. Integrate design process with environmental impact assessment. 7. Apply environmental impact assessment through the design process. From the descriptive studies we found that there is substantial difference in the environmental impact among products having the same functionality generated during the same design process. Analysis of industrial products available in the market show similar results. This means that design can substantially affect the impact created by a product. In our studies, designers did not consider environmental impact as a criterion in evaluation and we also identified the typical activities performed by designers during An Interactive Support for Developing Environmentally Friendly Product Lifecycles designing that must be allowed, supported or taken into account while developing a support for environmentally friendly product lifecycle design (EFPLD). The requirements of the designer for support are: tools should be proactive, easy to learn, understand and use, allow understanding of design rationale, act as a checklist, reduce total time, store knowledge and experience as know‐how backup, useful in all stages of design, not require too much extra effort for analysis, integrated to CAD, aid in trade off between choices, show uncertainty analysis, aid in analysis & improvement, and consider all lifecycle phases. A holistic framework, ACLODS (is a acronym of the six dimensions) constituting the following six dimensions: a) Activities, b) Criteria, c) Lifecycle phases, d) Outcomes, e) Design stages, and f) Product Structure was proposed for development of environmentally friendly product lifecycle designs. Through descriptive studies we found mainly 4 categories and associated sub categories of uncertainty in information with respect to LCA in design. The four categories are uncertainty in product structure, lifecycle phases, data quality, and methodological choices. The sub categories are assemblies, sub- assemblies, parts, relations, and features in product structure, material, production, distribution, usage, and after‐usage in lifecycle phases, temporal relevance, spatial relevance and sample size in data quality, and temporal relevance, spatial relevance, and comprehensiveness in methodological choices. At any point of time, uncertainty in information available is an accrual of the combination of the individual uncertainties. A method called confidence weighted objectives method is developed to compare the whole lifecycle of product proposals using multiple evaluation criteria under various levels of uncertainty. It is compared with normal weighted objectives method and found to be better since it estimates the overall worth of proposal nd confidence on the estimate, enabling deferment of decision making when decisions cannot be made using current information available. A new integrated platform IDEA‐SUSTAIN is developed in this thesis for supporting synthesis in product development on a commercial CAD workspace, while also aiding automated capture and storage of the rationale behind the decisions for retrieval whenever required during design. It is extended to support life cycle assessment of product proposals created by automatically extracting the information already stored while designing and ask for other information required to model the lifecycle without much extra effort from the designer. Then it uses the method for uncertainty reasoning developed also as a part of this research to estimate the level of confidence on the impact value owing to the incompleteness in knowledge available. The estimation is possible at part, assembly or product levels, for a single lifecycle phase or multiple phases. Using in‐house design exercises and feedback questionnaire evaluation of support is done. The usage of Idea‐Sustain has been found to be the best for both generation and evaluation of product proposals. The two computer aided tools – software (LCA) and Idea-Sustain-are compared with each other for fulfilling the functional requirements by analysing the feedbacks given by the designers on these tools against these requirements. Idea‐Sustain fulfilled well most of the requirements while the software (LCA) fulfilled only some of the needs, that too less effectively.

By measuring intentions to purchase, this research gives insight into environmental attitudes, pressures to purchase environmentally friendly apparel, factors that inhibit environmentally friendly apparel purchasing, awareness of environmentally friendly apparel purchase options, and marketing insight into the eco-friendly consumer. The theory of planned behavior (TPB) was used to assess consumer purchasing intentions for environmentally friendly apparel. The TPB consists of a three-pronged measurement: individual attitudes, subjective norms, and perceived behavioral control. Individual attitudes were gauged on three dimensions which included environmental attitudes, demographic patterns, and environmentally friendly apparel purchase intentions. Subjective norms involve social pressure to engage in eco-friendly behavior, perceived individual environmental impact, and desire for uniqueness in dress. Finally, perceived behavioral control was studied through previous environmentally friendly apparel purchases, accessibility of environmentally friendly apparel purchase options, and cost of environmentally friendly apparel. The results revealed that individual environmental attitudes, social pressure to behave environmentally friendly, perceived individual environmental impact, desire for uniqueness in dress, past environmentally friendly apparel purchases, accessibility of environmentally friendly apparel purchase options, and cost of environmentally friendly apparel all have an impact on intentions to purchase environmentally friendly apparel. The variable with the strongest relationship to intentions was social pressure. A demographic profile of intent to purchase environmentally friendly apparel, however, was not possible with this sample. This indicates there is not specifically one type of person who purchases environmentally friendly apparel.

The thesis deals with the problem of global ecological crisis caused by excessive consumption of material goods, particularly in countries of "The Rich North" (western countries). In the theoretical part I set up individualized man as a consumer in the system of modern society, which indicates the conditions of its existence mainly through the market. I discuss the possible way out of the ecological crisis through ideological changes in the company initiated from the "bottom", based on the internalization of values leading to responsible and moderate consumption. I demonstrate alternative ways of life, environmentally friendly in terms of consumption, and discuss the obstacles and ways of its spread. The research was conducted through interviews with eco-advisers who are dealing with consumption, as potential "opinion leaders" in this case. I tried to look their conception of responsible consumption and their potential impact on society in favor of spreading the idea of an environmentally responsible way of life Key words Ecological crisis, consumption, consumerism, modernity, individualization, values, responsible consumption, modesty, environmentally friendly way of life

Recent studies have suggested that an increasingly large proportion of a building's energy cost consists of energy consumption during the building process, before the building becomes operational. A large part of this "early energy" consists of indirect energy that has been used to manufacture building materials and components and to transport material to the construction site. Furthermore, there is the more direct energy used in construction projects such as construction electricity, district heating, LPG and diesel fuel used on-site. These costs are in a more direct and comprehensible way linked to the construction site and can be influenced by the developer and / or contractor. Therefore, this report focuses primarily on the direct energy involved during a building’s constructions phase. The problems that exist today are several. For example, both clients and contractors have very poor means of monitoring energy consumption on construction sites thus making it difficult to optimize the costs. There are no reliable statistics regarding energy usage, which makes it difficult to analyze problems and to suggest improvements. One of the reasons is that the cost of construction energy, or at least the monetary value of the potential savings, is considered to be negligible in the context of a major construction project and the subject has therefore rather low priority. Furthermore, the clients rely heavily on the contractor’s expertise and have big faith in the contractor’s ability to optimize energy usage. On the other hand, contractors assume that the customers are fully informed and aware of their own needs and that the contractor should only offer what the customer asks for, as cheaply as possible. However, it would be possible for both parties to make substantial savings by adopting a more efficient energy management. In order to achieve this, construction energy issues have to be considered early in the planning process and throughout the entire project. The best results are achieved when the developer and contractor share a common vision and there is open exchange of knowledge and experience. To facilitate this dialogue and to create a tool to address the issue early in the project, this exam-work has led to a prototype for a template that is intended to be used as a letter of intent between the parties, by which they can jointly or individually clarify and specify their energy goals within a specific project / Nya utredningar tyder på att en allt större andel av en byggnads energiåtgång återfinns i de tidiga skedena, innan huset ännu tagits i drift, det vill säga under produktionsfasen. En stor del av denna "tidiga energi" består av indirekt energi som har använts i framställningen av byggmaterial och byggnadskomponenter samt till transporter för att få materialet på plats. Därtill finns den mer direkta energin, i form av byggström, fjärrvärme, gasol och diesel som används på byggena. Dessa kostnader är på ett mer direkt och lättöverskådligt sätt knutna till byggarbetsplatsen och bakomliggande processer är något som beställare och entreprenör har inflytande över och kan förbättra. Följaktligen kommer denna rapport främst behandla den direkta energin som används under en byggnads uppförandefas. Problemen som finns idag är flera. Delvis har många aktörer, både på beställar- och utförarsidan, bristfälligt statistiskt underlag angående byggenergin. Detta resulterar i en undermålig eller obefintlig uppföljning och identifiering av förbättringsmöjligheter gällande energianvändningen. En bidragande anledning till problemet är att kostnaden för byggenergi, eller åtminstone det monetära värdet av en potentiell besparing, av många anses som en försumbar del av ett stort byggprojekt och frågan blir därför nedprioriterad. Vidare verkar det inom beställarleden finnas en viss överdriven tilltro till entreprenörernas expertis och vilja att utveckla branschen i energihänseende medan det omvända förhållandet delvis råder bland entreprenörerna, där man utgår från att kunderna är aktiva beställare som vet vad de vill ha. Entreprenörerna föreslår sällan alternativa lösningar utan försöker snarare uppfylla kundernas kravspecifikationer till ett så billigt pris som möjligt. Det skulle dock kunna vara möjligt för bägge parter att spara både pengar och koldioxid genom en effektivare energihantering. Dessa åtgärder kräver att byggenergifrågan finns med tidigt i projekten och i planeringsprocessen. Allra bäst resultat uppnås när beställare och entreprenör har en gemensam målbild och ett öppet utbyte av kunskaper och erfarenheter. För att underlätta denna dialog har vi tagit fram ett förslag till en mall som är tänkt att fungera som en intentionsförklaring mellan parterna varigenom man gemensamt eller individuellt kan tydliggöra och konkretisera energimålen i byggprojekten. Vi har även tagit fram förslag till formuleringar gällande energieffektivitet som kan inkluderas vid upphandlingar.
