1 Amman, Jordan, 30 th June 2008 Life cycle assessment Introduction and application Dr. Fredy Dinkel Carbotech Inc., Switzerland Overview Sustainable development Request on a methodology for sound environmental decisions Short introduction to LCA Case study in the industry Use at regulations in Switzerland 1

2 Today it is well known that sustainable development is an important issue for the future of our society Generating tax and duties covering the caused cost Economy s bright future Business economics degree of innovation Stability on social welfare Social welfare, education Individuals health Contiguous education local Regeneration of the Nature global What is needed to reach the target of sustainable development (SD)? There is common sense that the protection of the environment from problematic impacts is important but normally decision are made on economic criteria. Protection of the environment is good but earning or saving money is better What is the consequence of this mind set? 2

3 To focus just on the economy......is like looking at a one dimension al picture Sunset at the dead sea A two dimensional picture is better...is like looking at a one dimension al picture 3

4 The one dimensional view is not enough Needs Valuation Every activity has also influences on humans and the environment like Economy s bright future Health problems from air pollution, Water pollution Noise, Accidents, Impacts on nature, Resource needs Social welfare, education To bring these dimensions together and introduce environmental aspects into management decisions it is important to valuate and quantify the environmental impacts. Regeneration of the Nature According to the evaluation of ecological impacts a lot of questions arise Valuating environmental impacts Which are the most relevant impacts to consider? toxic emission to the water climate change reduction of forests toxic releases to the air reduction of soil fertility water pollution... 4

5 According to the evaluation of ecological impacts a lot of questions arise Valuating environmental impacts How to reduce the impacts on the environment? Which is the most efficient way to do it? How to measure the environmental impacts? What is relevant? How to quantify environmental impacts to correlate them with quantitative economic data? Because of the complexity of the system the evaluation is often reduced to selected aspects or simple rules, like: Problematic substances: Chemicals, Toxic emissions, Threshold values Discussed problems: Energetic resources, Global warming Obvious problems: Wastes, Water, Noise Products from plants are always eco-friendly Products from the industry are problematic Is that enough? Let s have a look at some examples. 5

6 For example: energy from burning of fuels is related with a lot of emissions, toxic and leading to climate change On site emissions: Carbondioxid CO 2 Nitrogenoxids NO x Hydrocarbons C m H n... No emissions on site! To conclude, that electricity is better for the environment, must not be true! Because production is also related to emissions. But it is not sufficient to focus on local emissions Needs Valuation Life cycle Including different aspects The production of 1 MWh electricity from a lignite power plant is related with: 200 kg of Wastes and 1200 kg of Carbon dioxide emissions 10 kg of emissions to the water, from organics to heavy metals 250 m 3 of water use For the right answer You have to take into account The whole life cycle and The different impacts to the environment 6

7 Water Essential for life It is not always easy to get drinking water To prevent water from pollution is essential Example Water The visible pollution is only one aspect 7

8 Cotton textile a product from nature Example Natural products The production of cotton uses large amounts of pesticides and fertilizers so it is linked with emissions to soil and water. But this is not all This was a production site of cotton Enormous amounts of water are used to plant cotton The question arise if a synthetic textile could be mor eco-friendly 8

9 Problems with water can also be caused by emissions to the air or the soil For example: Needs Valuation Life cycle Including different aspects Emissions like CO 2 causing climate change this can have a strong influence on the water Emissions of NO x from traffic or energy systems causes eutrophication Pesticides in agriculture Requests to the method Science Specialist Scientific complete Practical Flexible Decision-maker Base for decision Consider a large amount of different impacts Considering the whole life cycle Quantifying the environmental impacts Good decision base Scientific bases Easy to realize 9

10 We life in a global world and have to take into account the whole life cycle and evaluate the different impacts into key figures This is the aim of the methodology of Life Cycle Assessment (LCA) Products Judgement of processes and technologies from the ecological point of view Analysis/strategy planning for product development and optimization Eco audits (EMAS, ISO 14000) Ecological business balances Data base for ecological annual reports Framework LCA Methodology LCA of product or service is complex, it undergoes subjectivity There was a need in the 90 s to elaborate a standardized assessment process It was elaborated by Society of Environmental Toxicology and Chemistry (SETAC) And standardized by International Standardization Organization (ISO) 10

Government, public, stakeholders It is a globally recognized method 12

13 Application of LCA in industry In an environmental management system - for finding relevant reduction potential and measures, it is important to use: Quantitative methods like LCA to find the most efficient environmental reduction potentials. wood brigde, long lifecycle Because they can be linked to economic indicators the most wood brigde wood brigde, air dried efficient measures according to economy and ecology can be found leading to Eco Efficiency ecomomic efficiency low high low wood brigde, energy from wood composite bridge high ecologic efficiency Swiss post service The postal service in Switzerland Schweizer Post being the largest transport company in Switzerland has started to use LCA 10 years ago and used it for their strategic decisions. In a first step they have done a overall LCA on the company to see what are the main reasons for the environmental impacts. 13

19 Introducing the concept of overall environmental impacts in Swiss regulation Regulations In the year 1998 the Swiss regulation on water prevention was modified by the following article concerning about the introduction of waste water in rivers or lakes : Art. 6 The threshold value can be relieved for industrial waste water if the over all environmental impact are lower by introducing the waste water into a water than other waste water treatments. The question arises: What means overall environmental impact Industrial case study The situation: An industry has waste water with propylene glycol. Which is not very toxic, but has a high BOD. The threshold values are not met. There is no waste water treatment plant near by. The technical solution: In Switzerland the used technique to treat the waste water, if there is no waste water treatment plant, is: Evaporating the waste water and burning the concentrate in a waste incinerator. 19

20 The questions arised What is more problematic: The production of electricity The emissions to the air by burning the concentrate The emissions by the transports The energy used The wastes But No emissions on site or Industrial case study The water pollution Are there other possibilities? The global ecological view of the waste water treatment, in this special case Industrial case study 140 % 120 % relative Environmental Impacts 100 % 80 % 60 % 40 % 20 % % Normal technical treatment No treatment ventilation energetic recources non-renewable UBP

23 Introducing the concept of LCA in regulations Regulations In the regulation on the tax of mineral oil from 20 th January 2008 there will be tax reduction on fuels from renewable resources if the following conditions are fulfilled: The reduction of greenhouse gases over the whole life cycle will be reduced by 40% The overall environmental impact is not higher than the impact from the use of fossil fuels. It has to be proven by the applicant with an overall balance. Fusszeile Life cycle analysis It is a very powerful tool in Cleaner Production assessment As decision base for investments and improvements In regulation According to the E.U.: LCAs provide the best framework for assessing the potential environmental impacts of products currently available. Thank you for your attention 23

24 Assessment of the Environmental Impacts of Electricity Production and Heating sources In Jordan Goal of the Study Is to compare the environmental burdens of the production of electricity mix used in Jordan with the environmental burdens of Producing electricity by combined cycle gas power station. 1

25 Jordan Electricity Mix Jordan produces 90% of its electricity and imports 10% from Egypt and Syria. Jordan electricity Mix: It is found that about 70% of Jordan electricity is produced by Natural Gas and rest portion is generated by a mix of Heavy Oil, Diesel and Renewable Energy The data used in this study is based on electricity generation statistics in 2005 (statistical year book- Jordan, 2005). Assessment Methodology our analysis was based on a leading LCA software, where we used the Ecological Scarcity 2006 method that asses the effects of emissions (air, water and soil) on human health, ecosystems, climate change and use of fossil and natural resources. RSS has already purchased this software (Simapro) and has access to the largest international database on LCA. We are undertaking an LCA study for an important industry. 2

26 Analyzed system with the highest environmental Impacts Oil Gas Comparison of the environmental impacts to use electricity from the Jordan grid compared with the production of electricity in a combined cycle gas power plant Evaluation with ecological scarcity 3

27 Comparison of the environmental impacts to use electricity from the Jordan grid compared with the production of electricity in a combined cycle gas power plant Evaluation with ecological scarcity Results The study showed that power generation using NG Combined Cycle, best technology has lower impact on the environment. CO 2 emissions will nearly be reduced to the half. SO x emissions will be reduced by about 90%. NO x emissions will also be reduced by about 75% 4

28 Conclusion Producing electricity using NG combined cycle best tech. is more efficient than the current electricity mix used in Jordan. Combined cycle power generation is economically feasible and environmentally friendly. It does need new investments, but with rising prices it can be interesting economically. Energy Options In Jordan Goal of the analysis: To find the best source of heating with the least environmental Impacts 5

30 Adaptation to the Jordan situation Valuation methodology and databases The need for adaptation Actual LCA valuation methodologies and databases were developed in and for Europe and North America Some environmental problems as well as human activities are specific to countries or regions Thus, valuation methodologies and databases must be adapted to the Jordan situation 1

31 Adaptation of valuation methodology Ecological scarcity 2006 valuates environmental impacts according to Swiss environmental policy goals If a human activity generates an environmental impact in a field which is highly sensitive for Switzerland, it will be highly valuated Adaptation of valuation methodology Ecological scarcity 2006 does not highly valuate the use of water as there is no water scarcity in Switzerland However, Jordan is amongst the 5 countries suffering the most of water scarcity Thus, Ecological scarcity 2006 is to be adapted to take into account water scarcity in Jordan, but not only (greenhouse gases, air pollution, natural resources consumption, etc.) 2

33 Adaptation of databases Already adapted: Jordan electricity mix Refinery Planned adaptations: Traffic Waste Power production (solar energy) Agriculture Expected outcome Environmental impacts resulting from Jordanian activities are valuated according to a valuation methodology reflecting Jordanian environmental policy goals This will provide a reliable base for decision-making in all sorts of fields in Jordan (energy, water, transport, etc.) 4

34 Next steps What has been done Kick-off workshop was launched in January-February to give to local stakeholders an introduction to the LCA approach and its methodological framework. Enable them to understand the importance of such a tool in implementing eco-efficiency, better natural resource management and reducing pollution in Jordan. Raising of building capacity and now we have Necessary software tools Access to the largest international database on LCA Performed different case studies and a project for an important industry in Jordan 1

35 Looking forward to The experiences of the last month have shown that LCA can be a very powerful tool for Industries Government Public services To find the relevant environmental impacts Improvement potentials of these impacts To make Decisions for investments The choice of eco-efficient solutions Communication with stakeholders Our plans (1) Detect the relevant sectors with an overall Jordan LCA and the reasons for the environmental impacts like Human health from toxic emissions Reduction of natural resources by water consumption Influences on eco systems by emissions and land use. This gives a sound base of discussion with the ministries knowing the reasons and finding potential options of reduction, and then strategic development projects can be defined. 2

36 Our plans (2) Develop case studies in various sectors considered as hotspots in Jordan like energy, industry, water, traffic, waste, construction, house holds The economic aspects is possible to be included in all this analysis. This insures that the feasibility of proposed projects can also be evaluated from an economic point of view. How to materialize this plan This plan is necessary for different levels: -Governmental -Industry and services -Technical service providers; database and capacity building 3

37 On governmental level we are convinced there are following needs: Jordan needs clear and effective laws and regulations to support emerging sustainable development strategies and policies. Effective environmental policy and regulations have a potentially greater impact on sectors to address environmental problems at the source On industrial and services we are convinced there are the following needs: Good case studies to show that LCA Can provide them with good opportunities to find eco-efficient solutions Give a good base for investments Improve the environmental management Is a perfect tool for communication with stake holders Can open to Jordan companies European market 4

38 On technical level - database and capacity building we are convinced there are the following needs: A national team and a discussion between the different users Adoption to the Jordan situation the international database the valuation methodology We have just started to do it and invite you to join us. October workshop on LCA October workshop is open for all interested parties. So we invite you to discuss now the following issues What are the possible case studies What topics you suggest - Legislation -Needs of the industries -National information national database To take the opportunity to use the powerful tool of LCA for a sustainable development in Jordan. 5
