1. Life Cycle Assessment (LCA) LCA is a method that considers energy and raw material consumption, different types of emissions and other important factors related to a specific product’s entire life cycle from an environmental point of view. 4 (c) 2006 Dr. Bert Bras & Felipe Roman, Georgia Institute of Technology (for LCA)

Introduction LCA: 1. Life Cycle Assessment 5

1. Life Cycle Assessment Framework ISO 1404x Interpretation (ISO 14043) Goal and Scope Definition (ISO 14040) Inventory Analysis (ISO 14041) Impact Assessment (ISO 14042) Improvement Assessment / 6

Step 1: Coffee Maker Purpose of a LCA? Determine how to improve the environmental performance of a coffee maker Possible Decision criteria? o total energy consumed (cp. slide 5) o eco-indicator 99 score (EI99) o equivalent CO 2 produced (carbon footprint) Function of a coffee maker? Functional units? Cups of coffee poured, Time coffee is warmed etc. System boundaries? Five years of use, Europe, only production, usage & end-of-life stages 8

Establish purpose & goal Define decision criteria, function and functional unit Define system boundaries o Place (world/continent/country; cp. down right) o Life cycle stages (cp. top right) o Time (to be defined individually) Determine required data quality / sources (most complicated issue in practise) Step 1: Goal Definition & Scope

The more processes, the more complex … Raw Materials Manufacturing Process Energy Water Solid Waste Liquid Waste Gas Waste Manufacturing Process Energy Water Solid Waste Liquid Waste Gas Waste Manufacturing Process Energy Water Solid Waste Liquid Waste Gas Waste Manufacturing Process Energy Water Solid Waste Liquid Waste Gas Waste End Product 10 Step 1: e.g. Life cycle stages

Difficulties & Limitations of Step 1 How do you compare different products that provide similar functions or services? How do you compare similar products that provide multiple functions or services? How do you define more abstract functional units such as entertainment from toys or higher self-respect? Where do you stop drawing the bounds to your system? 11

Step 2: Inventory Analysis 1.Make a process tree or flow chart classifying events in a product’s life cycle 2.Determine all mass and energy inputs and outputs 3.Collect relevant data! 4.Make assumptions for missing data 5.Establish (correct) material and energy balance(s) for each stage and event 12

Difficulties & Limitations of Step 2 Finding data is hard and usually very time- consuming Published data on material loads exist, but is often inconsistent and/or not directly applicable Obtained data are usually discrete, static and linear (makes many simplifying assumptions) Mistakes are easily made in quantification Mass and energy balances may not be correct Results can be generalized improperly 16

Difficulties & Limitations of Step 3 Subjective, subjective, subjective!  Impact categories chosen  Indicators chosen for impact categories  How metrics / load affect impact indicators  Weightings used for impact categories Where are the impacts occurring?  U.S., Europe, Brazil? How much can that area take before it breaks down? Or can it handle it without any problems? How are managers and engineers supposed to know the effects of every load on the different impacts? 20

Step 4: Improvement Analysis 1.Identify areas & opportunities for improvement 2.Evaluate with respect to the original goal definition 3.Target lifecycle areas/processes/events with large impacts Large amounts with low hazard Small amounts with high hazard 4.Ask yourself: What are the resources required and risks involved? 21

Table Source & Figures from 1 st Slide: Ashby and coauthors, 2004, “The CES Eco-Selector – background reading”, 2 nd edition, University of Cambridge and Granta Design, pp General Comments / Discussion A domestic coffee maker is a simple product  How would it be different from a commercial coffee maker (e.g. Starbucks)? It is fairly representative of appliances - main impact is use phase  What other products have their main impact in the use phase? Which products have their main impact in the production or disposal phase? 23

2. LCA - Summary Focus should be on the product’s entire lifecycle, not the product itself We saw the main steps of LCA (ISO ) We saw the limitations & difficulties within each step of LCA Although LCA has various limitations, its underlying philosophy is the right direction 24

3. Environmental Management Systems 26

A management system means what the organisation has to manage concerning its processes or activities in order that its products or services meet the organisation’s objectives, such as satisfying the customer's requirements, complying to regulations or meeting environmental objectives 3. Environmental Management Systems 27

ISO 9000ff. and ISO 14000ff. are among ISO's most well known standards ever. They are implemented by more than a million organisations in 175 countries. ISO 9001 helps organisations to implement quality management. ISO helps organisations to implement environmental management. New 2010: ISO helps organisations to implement social responsibility. 3. Environmental Management Systems Surrounding/some connections: 28

ISO is for environmental management. This means what the organisation does, in order to: minimize harmful effects on the environment caused by its activities, to conform to applicable regulatory requirements, and to achieve continual improvement of its environmental performance. 3. Environmental Management Systems 29

ISO Most widely recognised and adopted standard > 130,000 organisations certified worldwide Well established, good reputation Internationally recognised Can take a long time to implement – especially within large complex organisations Can be costly to implement – tools and consultancy (in Europe also the EMAS system, not considered here) See additionally: Environmental Management Systems
