What is LCA? • Based in a systems approach to the product • Based in the functionality of the product • Covers the whole life cycle of all materials • Cover all impacts related to environment, health and resources
Life Cycle Assessment Framework Direct applications Goal and scope definition Interpretation Identification of Evaluation Significant issues Conclusions, recommendations and reporting Inventory analysis Impact assessment
LCA Application • Identify major contributors to environmental impacts • Compare different options for improvements • Provide guidance in long term strategic planning • Help to train product designers • Compare functionally of equivalent products • Inform customers about best selection and use of products
Five important questions to be answered from LCA studies • Do we have the right projects? (Technology, organisational, marketing, etc.) • Do we work with the right products/processes (Sunrise, mature or sunset products) • Do we have the right areas of concern? (Resources, climate change, toxicity, etc.) • Do we give attention to the right solutions? (End of pipe, process optimisation, product development) • Do we in fact have the right business idea?
Development in the types of LCA applications in companies Need of competence Marketing and external information Strategic decision making Increased knowledge own products Time
Driving forces - from “regarded as” to “documented as” • Increased marked demand for more eco-effective solutions in the society • The population and welfare growth in the global society in the next 20-40 years will demand 4-10 times more eco-effective solutions. • In 1999, several Environmental Management Tools have been standardised according to ISO-14000 series (14025, 14031, 14042-43) • The Kyoto protocol implementation in European politics will result in a need to document reductions in CO2 emissions as an instrument in tradable quotas

ENVIRONMENT AS A POSITIONING FACTOR : Focus on innovative, sustainable solutions Environmental concern as a business opportunity Product-oriented strategies, life cycle and systems approach Early users of new, innovative tools (LCA, EPI, EPD, Industrial Ecology etc. Systematic implementation of tools and knowledge ENVIRONMENT AS A MANDATORY SYSTEM Focus on simpler, more easy achievable solutions Environmental concern one of several factors to be considered in decision making More traditional process-orientation to problems Focus on ISO 14000 or EMAS Case to case application of environmental tools ENVIRONMENTAL CONCERN - A POSITIONING FACTOR OR A MANDATORY SYSTEM?
Assessment of packaging solutions - net material and energy efficiencies
ENVIRONMENTAL PERFORMANCE INDICATORS AND EVALUATION • Based on ISO 14031 Standard which was approved in spring 1999 • Based on environmental assessment of products and plant operation, and stakeholder assessment • Increasing information and management value by decreasing the number of parameters to a minimum of high priority areas of concern • Used for internal management decisions and external reporting to stakeholders
Traditional environmental parameters tons of coal combusted tons of oil combusted tons of virgin clay purchased m3 water used in process per y tons of CO2 emitted to air per y tons of NO2 emitted to air per y tons of SO2 emitted to air per y kg Hg emitted to air per year kg Zn emitted to air per year Environmental Performance Indicators # days per year with emissions beyond permit # MJ of fossil energy combusted/ton of product # Kg. GWA in CO2 units/ton of product # g heavy metals/ton of product # kg recycled materials per ton of product percent of sale related to products within green range ENVIRONMENTAL PERFORMANCE INDICATORS (EPI)
EPI Environmental Management Matrix- Type and frequency of indicators?
IMPLEMENTATION OF EPI’S IN MANAGEMENT/COMMUNICATION PROCESSES Define significant aspects Define EPI’s Define target values for EPIs External reporting Corrective measures Define responsibility Internal regular reporting Effect and activity indicators
ENVIRONMENTAL PERFORMANCE INDICATOR 1 - SHARE OF GREEN RANGE PRODUCTS TO TOTAL SALE
WHY USE A REFERENCE PRODUCT AS A STARTING POINT? • To identify the most important problems and sources for problems with existing products with similar functions, both concerning environmental impacts, life cycle costs and customer satisfaction (gap analysis) • To have a reference point to document improvements with a new product
STEP 2: IDEA GENERATION FOR PRODUCT SYSTEM IMPROVEMENTS • Systematic search for improvement options based on experiences from reference case • Identify options from four strategies for improvements
IDEAS FOR IMPROVEMENT OF LIGHT FITTINGS SYSTEM 1. A new design with 30% reduction in material consumption 2. Substitution of all aluzink parts with black tin 3. Use of recovered aluminum and steel as a substitute for 70% of the virgin materials. 4. Recover the most important weight fractions after use 5. 2x36W armatures or 2x58W armatures 6. Integration of energy conserving equipments (infra red switcher, day-light switcher, modern electronic reactors etc.),

LIFE CYCLE COST EVALUATION OF DIFFERENT OPTIONS FOR IMPROVEMENTS OF LIGHT FITTINGS
CORRESPONDANCE BETWEEN PRODUCT ECONOMY AND OPTIONS FOR IMPROVEMENTS OF PRODUCTS
CORRESPONDANCE BETWEEN CUSTOMER REQUIREMENTS AND OPTIONS FOR IMPROVEMENTS
ASSUMPTION IN THE DYNAMIC LCA MODEL - 10% annual increase in total environmental performance of the production of raw materials and assembly of the light fittings - 30% increase in environmental performance of the user phase each third year, by the release of new products. - 60% recovery and use of recovered steel and aluminum in the light fittings (scenario B), compared to 0% recovery in the reference case (scenario A) - Replacement of the light fittings 1, 2, 4 or 12 times during a twelve-year period by the user, with new and more innovative solutions.
ENVIRONMENTAL PRODUCT DECLARATIONS • ISO 14025 Guidelines for Environmental Product Declarations approved in summer 1999 - basis for industrial sectors and national/international approaches • Norwegian prestudy carried out in 1999 - methodology and format to be finished during autumn • Nordic project planned to be initiated during the winter 1999-2000.
Industrial Ecology - webs of value chains Two types of industrial ecology webs • Geographical webs (Eco-parks) • Functional webs (Offices etc.)
