Despite continuous efforts to reduce road noise emissions, road noise is still the dominant source of noise in Switzerland. Low-noise pavements are an effective measure for road noise mitigation, but besides their higher cost, their major drawback is a reduced service lifetime as compared to conventional pavements. How do these arguments compare in...

Despite the efforts to reduce road noise emissions, traffic noise is still the dominant noise source in Switzerland. Low-noise road surfaces (LNRS) are effective in mitigating traffic noise. But LNRS cost more and have a reduced service lifetime compared to conventional road surfaces. How do these aspects compare in a comprehensive view? To answer...

30 Jahre GAIA ‐ ein guter Zeitpunkt, um innezuhalten, zurückzublicken und einen Ausblick in die Zukunft zu wagen. Wir haben zwei Personen eingeladen, die wir zu ihren Eindrücken zur aktuellen Lage der Nachhaltigkeit und zu GAIA befragt haben. Die Interviewgäste sind: Arthur Braunschweig, Gründungsmitglied des Vereins Gaia, dessen Schatzmeister und...

Article de base sur l'analyse de cycle de vie ACV ou écobilan, comme outil pour entreprises et l'administration, pour l'analyse d'alternatives et pour la gestion environnementale, et sur l'histoire de l'ACV/écobilan d'un point de vue Suisse. Les sou-chapitres: - Comment réalise-t-on un écobilan ou une analyse de cycle de vie - Points cruciaux: les...

The “ibex fairstay” is a label for hotels denoting the hotels’ level of sustainability performance and management. In a comparative study, the ibex fairstay was seen as one of the best sustainability labels in tourism. Some 55 hotels and hostels are certified against the “ibex” method, a dozen of which with the highest “platinum” level. The methodo...

In LCA impact assessment methods, gravel has not been considered a scarce resource - until the Swiss Ecoscarcity method included it in its 2006 version. The paper discusses this development, presents arguments on the issue, and proposes ways how to go forward.

Comparing the methodological approaches of LCA (Life cycle assessment, as in ISO 14040) and of Greenhouse Gas Accouting (as e.g. in ISO 14067), such as the environmental and organisational scopes, the types of questions they answer, the typical applications. Includes a small explanatory case.

Recent developments within life-cycle impact assessment (LCIA) allow direct modeling of changes to predefined safeguard subjects that represent the environment to be protected. These changes are often expressed in a few damage indicators and calculated for each product alternative to be compared. This article analyzes the correlation among damage i...

The Swiss Ecological Scarcity method has first been introduced in 1990 and updated in 1997. Currently the Swiss version of this method is updated and extended. The update and extension of the method takes into account the recent developments in Swiss and European (as far as it is relevant for Switzerland) legislation and environmental targets. Furt...

Die vier unternehmerischen Dimensionen der Nachhaltigkeit – Markt, Finanzen, Soziales, Umwelt – eröffnen Unternehmen Potenziale für Risikominimierung, Effizienzsteigerung, Differenzierung, Innovation und Steigerung der Reputation. Dazu müssen alle vier Dimensionen in die Formulierung der Unternehmensstrategie und deren Umsetzung integriert werden....

This paper describes the assessment of the human health damages related to the man-made routine releases of radioactive material to the environment as reported in Life Cycle Assessment (LCA). The fate and exposure analyses are based on site-specific modelling of the French nuclear fuel cycle, from which generic exposure factors are derived. The eff...

LCA ecoscarcity weighting method, update 1997, published in the BUWAL (now: BAFU) series nbr. 297.

When defining the system boundaries of an LCA study, a number of delimitations have to be set: the choice of life-cycle phases to be considered, the choice of relevant processes within those phases, the timeframe of the selected life-cycle phases and processes, the geographical area, and the environmental interventions which are to be included. It...

LCA - Quo vadis? discusses overarching topics, new developments and major problems of Life Cycle Assessment (LCA), and compares LCA with site-specific environmental management. The text profits from two years of interdisciplinary, coordinated research activities of the Priority Programme Environment of the Swiss National Science Foundation. How sho...

Life Cycle Assessment, in short LCA, is a tool aiming at examining the environmental consequences of a product - or a service unit - over its whole life cycle “from cradle to grave”, In German language, the term “Ökobilanz” (“Ecobalance”) is used both for Product-LCA as well as for the environmental statement of a company. If used properly, LCA is...

Eco-balances are a set of instruments for the recording and evaluation of the ecological effects of products and processes. Eco-balances can enable weak points to be identified and an ecological evaluation to be made of alternatives in order to improve the ecological efficiency of products and firms. It is extremely important to have a clear descri...

Ökobilanzen sind Instrumente der Entscheidungs-Unterstützung, wenn es gilt, verschiedene Möglichkeiten einer Problemlösung möglichst systematisch, möglichst umfassend und zugleich möglichst rasch und kostengünstig auf ihre ökologischen Vor- und Nachteile zu überprüfen. Rückblickend auf drei Veranstaltungen in den letzten Monaten wird der Stand der...
