Future-Oriented LCA

  • ️Sat Sep 02 2017

Abstract

LCA is often applied for decision-making that concerns actions reaching near or far into the future. However, traditional life cycle assessment methodology must be adjusted for the prospective and change-oriented purposes, but no standardised way of doing this has emerged yet. In this chapter some challenges are described and some learnings are derived. Many of the future-oriented LCAs published so far perform relatively short-term prediction of simple comparisons. But for more long-term time horizons foresight methods can be of help. Scenarios established by qualified experts about future technological and economic developments are indispensable in future technology assessments. The uncertainties in future-oriented LCAs are to a large extent qualitative and it is important to emphasise that LCA of future technologies will provide a set of answers and not ‘the’ answer.

Appendix: Questions

Appendix: Questions

The questions are formulated as standard questions which can be specified further in the work in the different technology areas according to the needs. The questions ensure that different types of development mechanisms can be addressed in a systematic manner. It is not expected that answers can be found to all questions in all cases. There will probably be questions which cannot be answered or where only vague guesses can be suggested. One’s first answers to the set of questions can be taken up again later in the analysis process, whereby some of the answers and the understanding of the development dynamics can be refined.

The set of questions below is an example of questions that can be used for illuminating future developments in an area (the area in the example is energy technology). The questions can either be used in a questionnaire survey, for dialogue with individual experts or for reflection internally among the LCA analysts. It is structured in three sections:

  • Basics—what technology are we talking about.

  • Drivers for technology change.

  • Changes resulting from the drivers.

Both ‘positive’ and ‘negative’ drivers (barriers) are meant to be included. The types of driving forces addressed are:

  • Technical and technological issues.

  • Science and knowledge developments.

  • Energy systems —infrastructures.

  • Use of the technology—e.g. what role in the electricity systems?

  • Where, on which markets, is the technology used—how wide spread is the use?

  • Regional and geographical aspects.

  • Industrial production of the technology.

  • Innovation networks and innovation communities of the technology.

  • Public regulation and public support.

  • Societal and political concerns.

  • Environmental challenges and possible risks.

Each question can be asked for (a) the near future; (b) the midterm future and (c) the long-term future.

  1. 1.

    Basics (in brief)

    1. 1.1

      What technology is addressed?

    2. 1.2

      What different basic technology concepts are available or seen as possible alternatives in the future? By technology concepts we mean for example, thin-film PV, silicon PV, etc.

    3. 1.3

      What are the main elements (sub-technologies) of these technology concepts? e.g. tower, blades, foundation, net connection, etc. of off-shore wind farms, etc.

  2. 2.

    Drivers for technology change

    By ‘drivers’ is both meant ‘positive’ and ‘negative’ (limiting) factors influencing the development of the technology.

    1. 2.1

      For each main element: What are the relevant developments in techniques and technological knowledge connected to this component?

    2. 2.2

      For each main element: What relevant influences from generic techno-scientific areas as material research, nanotechnology , biotechnology, biochemistry and information and communication technology can be identified as drivers for change? For example, functional surfaces, biochemical processes, corrosion knowledge, material techniques, sensor technology, microbiologic processes, etc.

    3. 2.3

      What are the relevant developments in integration of the technology in the energy systems and infrastructures? For example, integration technologies, institutional and organisational arrangements, development of fuel supply chains , regulatory procedures, etc.

    4. 2.4

      What are the relevant developments in the use of the technology: what role will it have in electricity systems? For example, central/decentral production; general purpose or specific purpose, niche markets, etc.

    5. 2.5

      What are the relevant developments in dissemination of the technology—how widespread will the use be; on what specific markets?

    6. 2.6

      What regional/national/geographical aspects can be identified as drivers for technology change? For example, specific conditions in some regional electricity systems, climatic aspects, etc.

    7. 2.7

      What relevant developments in industrial production of the technology can be identified as drivers for technology change?

    8. 2.8

      What relevant developments in the knowledge community and the network of innovators of the technology can be identified as drivers for technological change? For example, developments in the ‘industrial sector’ of the technology, industrial innovators/manufacturers, research programmes, other support institutions, etc.

    9. 2.9

      What public regulation and public support can be identified as drivers for technology change? For example, market support, development programmes, etc.

    10. 2.10

      What public, societal and political concerns can be identified as drivers for technology change? e.g. security of supply, employment, safety issues, emission restrictions, etc.

    11. 2.11

      What developments in environmental challenges and risks can be identified and become drivers for technology change?

  3. 3.

    Resulting changes from the drivers

    This section concludes from section 2, sketching the picture of the technology in the short-term future, medium-term future and long-term future and pointing out relevant LCI issues.

    1. 3.1

      Taken into account the questions in section 2—What main development path can be identified for the technology?

    2. 3.2

      Taken into account the questions in section 2—What relevant alternative/extreme development paths can be identified?

    3. 3.3

      Direct changes: Technology change.

      Picture of the future technology: What will, in brief, be the characteristics of the technology, its design, costs, use and life cycle?

      • Total design and selection of technology concept (also covering material use).

      • Design and the main sub-technologies/main parts.

      • Production processes.

      • Installation, e.g. system/support structure, foundation, site preparation, power conditioning equipment, land requirement and storage requirement.

      • Operating and maintenance.

      • Dismantling and waste handling.

    4. 3.4

      Expected impacts on LCI issues

      How will these changes lead to changes in LCI issues (material/resource consumptions, environmental impacts, etc.)

      • Total design and selection of technology concept (also covering material use)

      • Design and the main sub-technologies/main parts

      • Production processes

      • Installation, e.g. system/support structure, foundation, site preparation, power conditioning equipment, land requirement and storage requirement.

      • Operating and maintenance

      • Dismantling and waste handling
