Résumé :

Många länder försöker minska sitt användande av fossila bränslen och istället använda sig utav förnyelsebara alternativ. Ett vanligt sätt att göra detta är att gå från bensindrivna motorer till eldrivna. Denna studie undersöker därför produkter ur samma produktsortiment som har samma grundfunktion och användningsområde men olika drivmedel. Syftet med detta är att få ökad förståelse för produkternas kostnader samt öka förståelsen för hur deras drift påverkar miljön. Studien genomfördes som en fallstudie på Swepac i Ljungby. Studiens genomförande följer delar ur LCC, LCA, CELA och break-even met

Résumé :

In recent decades, life cycle assessment (LCA) has become a commonly used approach worldwide when studying environmental impacts linked to waste management systems. These systems are of a complex nature which includes everything from technical solutions, the environmental influence, and various stakeholders. To facilitate studies within this area of research, different LCA models are often utilised. WAMPS is a software specifically developed for assessing the environmental and economic impacts for a waste management system. During recent years, the work to bring the model up to date has begun

Wind energy technologies are considered to be among the most promising types of renewable energy sources, which have since attracted broad considerations through recent years due to the soaring oil prices and the growing concerns over climate change and energy security. In Kuwait, rapid industrialisation, population growth and increasing water desalination are resulting in high energy demand growth, increasing the concern of oil diminishing as a main source of energy and the climate change caused by CO2 emissions from fossil fuel based energy.

Global warming is one of the biggest challenges of our society. The road transport sector is responsible for a big share of Greenhouse Gas (GHG) emissions, which are considered to be the dominant cause of global warming.

Résumé :

There is an urgency within the building sector to reduce its greenhouse gas emissions and mitigate climate change. An increased proportion of biobased building materials in construction is a potential measure to reduce these emissions. Life cycle assessment (LCA) has often been applied to compare the climate impact from biobased materials with that from e.g. mineral based materials, mostly favouring biobased materials. Contradicting results have however been reported due to differences in methodology, as there is not yet consensus regarding certain aspects. The aim of this thesis is to study t

Pour établir et tester un cadre méthodologique de l’ACV, adapté à cet objectif, des ITKv réels et variés visant un même objectif qualitatif sont nécessaires. Nous propo

Résumé :

In stainless steelmaking, around 68% of the total greenhouse gas emissions come from the processing of raw materials. Thus, it is important for steelmakers to make efforts together with their raw material suppliers to implement low-carbon initiatives. To facilitate such initiatives, assessment of raw materials will provide guidance. In this work, the assessment of materials consists of two parts: i) different production scenarios are studied by using a static process model coupled with life cycle assessment approach to investigate the reduction potential of environmental impacts for Mo and Ni

Résumé :

With global emissions estimated at 7.1 Gt CO2 eq per annum, livestock represents 14.5% of all human-induced emissions and it is considered to be the largest source of greenhouse gas (GHG) emissions from the agricultural sector. However, livestock can contribute to convert nutrients from plant biomass into animal-sourced foods, which are rich in essential macro and micronutrients in the form of milk and meat, thereby utilizing resources that cannot otherwise be consumed by humans. Livestock also contributes to global food security and poverty reduction, providing regular income to producers. To

Résumé :

The purpose of this study is to compare the life-cycle cost and environmental impact of the existing fuel-based propulsion system, on public commuter ferries in Stockholm, with a battery based propulsion system. The study is divided into multiple layers. First, the operating characteristics of the route Line 80 within Stockholm’s waterborne public transportation (WPT) are collected, such as fuel consumption, propulsion power output, speed, voyage time and propulsion system configuration. Second, based on the energy demand of the route, important parameters related to the existing fuel-based pr

A construção civil é responsável por relevante impacto ao meio ambiente, da extração das materiais-primas até a disposição dos seus resíduos em aterros. A avaliação do ciclo de vida (ACV) é uma ferramenta que possibilita a estimativa dos impactos ambientais potenciais do setor de forma sistemática. A simplificação da ACV, pelo uso de dados secundários e redução do escopo do estudo, facilita sua implementação como ferramenta de promoção da sustentabilidade. O objetivo dessa dissertação é estimar faixas dos cinco principais indicadores do setor de blocos de concreto do mercado brasileiro pela si

I Sverige används många olika interiöra golvmaterial i offentliga byggnader. Studien har undersökt fyra interiöra golvmaterial, keramik, enomer, massivt furu och linoleum. Dessa material är vanligt förekommande i svenska offentliga miljöer och de jämfördes ur ett livscykelperspektiv. Studien undersökte materialens olika livsskeden, från produktion till slutskede och omfattade materialens totala GHG-utsläpp för en referensbyggnad med en livslängd på 75 år, belägen i Växjö.Denna fallstudie visar att en byggnads klimatpåverkan går att minimera vid val av interiört golvmaterial.

Résumé :

L'analyse de cycle de vie (ACV), telle qu'elle est pratiquée aujourd'hui, peut conduire à des résultats biaisés. L'utilisation de cet outil s'avère particulièrement sensible dans des cadres réglementaires. En effet, au lieu d'inciter les entreprises à réduire leurs impacts sur l'environnement, les certifications obtenues à partir des ACV risquent de produire un effet contraire : comme elles tendent à récompenser des moyennes industrielles plutôt que les résultats propres aux entreprises, elles peuvent détruire toute incitation pour ces dernières à agir correctement sur le plan environnemental.

Résumé :

River restoration projects are being installed worldwide to rehabilitate degraded river habitat. Many of these projects focus on stream habitat improvement (SHI), and an estimated 60%of the 37,000 projects listed in the National River Restoration Science Synthesis Program focus on SHI for salmon and trout species. These projects frequently lack a sufficient monitoring program or account for the environmental costs associated with SHI. The present study used life cycle assessment (LCA) techniques and topographic effectiveness monitoring to quantify environmental costs on the basis of geomorphic

Il trasporto di persone rappresenta una delle principali fonti di sostanze inquinanti e climalteranti: in l’Italia il settore dei trasporti è responsabile di oltre il 25% delle emissioni totali di CO2, oltre che di migliaia di tonnellate di altri inquinanti. Gli organismi di Governo ribadiscono da tempo la volontà di indirizzare il mercato automobilistico verso vetture meno inquinanti, tuttavia non è ancora chiaro quali tipologie di propulsioni siano più ecocompatibili.

With global emissions of human activities that drive climate change on the rise, global institutions and authorities are trying to introduce new regulations in the industry, in order to accomplish a significant reduction of carbon emissions. In order for companies to be more effective in reducing carbon emissions, not only from their products but also along their value chains and product portfolios, it is of vital importance to understand and quantify them. Following that need, tools that can measure the carbon footprint of various corporate operations (carbon calculators) have risen in popula
