Life cycle assessment (LCA) has a number of defining characteristics that enables it to address questions that no other assessment tools can address. This chapter begins by demonstrating how the use of LCA in the late 2000s led to a drastic shift in the dominant perception that biofuels were “green”, “sustainable” or “carbon neutral”, which led to a ...

This chapter deals with the application of Life Cycle Assessment to evaluate the environmental sustainability of agriculture and food processing. The life cycle of a food product is split into six stages: production and transportation of inputs to the farm, cultivation, processing, distribution, consumption and waste management.

Cradle to Cradle (C2C) offers a positive vision of a future, where products are radically redesigned to be beneficial to humans and the environment. The idea is not to reduce negative impacts (as in LCA), but to increase positive impacts. This chapter presents the C2C concept and its relationship with the circular economy, the C2C certification and ...

We present a very simple algorithm for the Least Common Ancestors problem. We thus dispel the frequently held notion that optimal LCA computation is unwieldy and unimplementable. Interestingly, this algorithm is a sequentialization of a previously known PRAM algorithm.

Analysis and refutation of the LCAS
ACM SIGPLAN Notices, 1991A Language Compatible Arithmetic Standard (LCAS) has been proposed as International Standard ISO/IEC 10967:1991 for Language Compatible Arithmetic , Project JTC. 22.28, Version 3.1 (1 March 1991), by Drs. Mary Payne and Brian Wichmann. An earlier version appeared in both ACM SIGNUM and ACM SIGPLAN 25 1 (Jan.

Combining LCA with Thermodynamics
2007Life Cycle Assessment (LCA) is the most promising methodology to assess environmental impacts of products, services and processes. Its scope of application is constantly evolving, including e.g. application to regional scales and assessing societal consumption patterns.

An Illustration of the LCA Technique
2008It has been mentioned in Chapter 12 that Life Cycle Assessment (or LCA) is one of the analytical instruments within the toolbox for analyzing the interface of economy and environment. This section provides a worked example of the LCA technique. It is a fairly elaborate demonstration of a quite simple hypothetical product system.
