This first hands-on guide to ISO-compliant Life Cycle Assessment (LCA) makes this powerful tool immediately accessible to both professionals and students. Following a general introduction on the philosophy and purpose of LCA, the reader is taken through all the stages of a complete LCA analysis, with each step exemplified by real-life data from a m...
This chapter spans the time from the early days of Life Cycle Assessment—LCA (the time of the so-called ‘proto-LCAs’ between about 1970 and 1990), until recent trends of simplified/streamlined LCAs, the footprint specifications (carbon footprint, water footprint) and Life Cycle Sustainability Assessment—LCSA.
Important benchmarks along this span ar...

Purposes
The revision of the ISO LCA (life cycle assessment) standards in October 2006 brought some changes of the critical review process compared to the older series ISO 14040–43 (1997, 1998, 2000a, b). Furthermore, the importance of LCA has grown rapidly in recent years, but this growth was not accompanied by a corresponding increase of knowledg...
Background
The editor of this journal has been waiting for such a contribution of the life cycle assessment (LCA) practitioners and users for years, since the last debate of this kind dates back to beginning of the new century. It is remembered as the “Two planets debate” and coincided with the emergence of life cycle management, i.e. the use of li...
1 IntroductionSociety of Environmental Toxicology and Chemistry(SETAC) has published a code of practice for environmentallife-cycle costing (LCC), which provides a framework forevaluating decisions with consistent, but flexible systemsboundaries as a component of product sustainabilityassessments (Swarr et al. 2011). The code of practicebuilds on a...
This book provides detailed information about comparative LCA of different solders used in electronics. As Life Cycle Impact Assessment, the Japanese LIME method is used.
In a recent letter to the editor, Jørgensen et al. questioned that life cycle costing (LCC) is relevant in life cycle-based
sustainability assessment (LCSA). They hold the opinion that environmental and social aspects are sufficient. We argue that
sustainability has three dimensions: environment, economy, and social aspects in accordance with the w...
This note describes the “a posteriori” critical review process of a large Life Cycle Assessment (LCA) study. This LCA study
covered nine different recycling options of used tyres. The review was conducted by an international and multipartite seven-member
review panel. It should be noted that the preliminary administrative tasks took more time than...
Polyvinylcarbazol (PVCA) zeigt im festen Zustand Excimerfluoreszenz. Diese Fluoreszenz wird durch geringe Mengen Perylen, Hexachlor-p-xylol (HCX) und Trinitrofluorenon (TNF) gelöscht. Die Messung der Fluoreszenzquantenausbeute des PVCA als Funktion der Löscherkonzentration zeigt, daß die Energieübertragung durch Excitonendiffusion zustande kommt. Ü...
The predecessor of today's increasingly important ecological balances was the Limits of Growth Report published by the Club of Rome in 1972. Ecological balances cover mass and energy flows and emissions from the raw materials via intermediates all the way to the end products, as well as waste disposal. This also includes the balance of ecological a...
Das Fluoreszenzspektrum von Biscarbazolylpropan (BCP) weist eine konzentrationsunabhngige Excimerbande auf. Die Quantenausbeute der Monomerfluoreszenz ist nur etwa halb so groß wie bei Carbazolderivaten, die keine intramolekularen Excimere bilden können. Monomer- und Excimerfluoreszenz von BCP werden durch Sauerstoff unterschiedlich gelöscht.Die qu...

The book focuses on environmental LCC but also analyzes conventional LCC and societal LCC, providing case studies for each. It presents the link between life cycle costing and life cycle assessment and then explores public, private, and societal options. The book also explains all components of the method using the cross-cutting example of a washin...

Monomeric carbazole derivatives show phosphorescence in the wavelength region between 400 and 500 nm. Poly(vinyl carbazole) (PVCA) in dilute frozen solutions also shows phosphorescence in this region and, in addition, delayed fluorescence owing to triplet-triplet annihilation. The latter depends on the molecular weight of the polymer, high-molecula...
The photostability of UV stabilizers of the ortho hydroxybenzophenone type is discussed in terms of excited state proton transfer and radiationless transitions in the “phenol” and “quinone” tautomers. The first triplet state of the phenol form derived by quenching experiments is located between 22,000 and 20,090 cm−1. These limits of T1, together w...

Background
Life cycle assessments have been performed using different methods before the name was coined since about 1970 in several countries of North America and Europe. It was the merit of SETAC to start a standardization process which culminated in the LCA-guidelines ('A code of practice') in 1993...
Background The critical review is an important, though not always well understood and correctly applied element of Life Cycle Assessment studies. It is the intention of this paper to analyse the relevant standards and to present personal experiences in conducting critical reviews.Results and Discussion A peer review for LCA-studies was first propos...
Background
LCA is the only internationally standardized environmental assessment tool (ISO 14040-43) for product systems, including services and processes. The analysis is done ‘from cradle-to-grave’, i.e. over the whole life cycle. LCA is essentially a comparative method: different systems fulfilling the same function (serving the same purpose) ar...
To me, the speed in the development of Life Cycle Assessment seems to be breath-taking. Last year we forgot to celebrate the 10-year jubilee of SETAC's 'Code of conduct' and the Sesimbra Workshop, and nobody reminded the missing reference to this milestone towards standardization. The main stream of the development led to ISO 14040-43, but there we...
Ecological Balances as an Instrument for Product Evaluation. The predecessor of today's increasingly important ecological balances was the Limits of Growth Report published by the Club of Rome in 1972. Ecological balances cover mass and energy flows and emissions from the raw materials via intermediates all the way to the end products, as well as w...
We would like to report on an innovation to be incorporated in Int J LCA beginning with the January edition in 2003; it concerns the expansion of the journal by a section on LCM (Life Cycle Management). This new section will clearly be separated from the LCA 'nucleus', has an Editorial Board of its own and is peer-reviewed as well. This activity ta...
Sustainability-a term originating from silviculture, which was adopted by UNEP as the main political goal for the future development
of humankind-is also the ultimate aim of product development. It comprises three components: environment, economy and social
aspects which have to be properly assessed and balanced if a new product is to be designed o...

The background of this work is the international decision process with regard to the selection of chemicals to be assessed with priority. In order to stress the precautionary principle, mass flows were analysed rather than concentrations, threshold values, etc., as preferred by the chemical legislation (which still excludes the marine area). Lindan...
Life cycle assessment (LCA) often seems to be "timeless", since it compares functional units of analysed alternatives per se. It is demonstrated that temporal aspects enter LCAs, however, in all main components from goal definition and scoping to valuation in an ad hoc manner; in fact, it cannot be without time. Its methodology and practical releva...
