Abstract

This thesis aims to assess potential environmental impacts of media and communication and to contribute to the development of methods for sustainability assessment. Although the main focus is on printed and electronic media products and environmental impacts, a broader sector analysis is also included and social aspects are discussed. The thesis provides a review of different environmental assessment tools in order to better understand their relationships and the appropriateness of different tools in different situations. Life cycle assessment (LCA) is used to assess printed and electronic versions of newspapers, books and invoices. Results of the screening LCAs of newspapers and books indicate that when comparing printed and electronic versions there are benefits and drawbacks for both. For news and books read on e-reading devices with energy efficient e-ink screens, the main environmental impacts in the studies stemmed from the production of the device and partly from disposal, with the latter having the potential to reduce some environmental impacts through recycling of materials. However, there are data gaps regarding the production of the e-reading devices, most notably for the e-ink screen and the waste management of obsolete e-reading devices. Existing data on internet energy use are uncertain. The potential impacts from a hypothetical total change from paper invoices to electronic invoices in Sweden were assessed through a screening consequential LCA regarding greenhouse gas emissions and cumulative energy demand. The results indicate that emissions and energy demand could decrease as a result of a change. The screening LCAs performed indicate that users’ practices could substantially influence the environmental impacts. Key factors which can influence results and comparisons of printed and electronic media products are total use of electronic devices, total use of printed media, amount and type of paper, energy use of electronic devices, potential printing of electronic media, electricity mix, and the system boundaries set for the assessments.

To get a wider perspective, a sector study of the ICT sector and media sector concerning global greenhouse gas emissions and operational electricity use was performed. It was estimated that the contribution to global greenhouse gas emissions in 2007 was roughly 1-2 % for each sector. To assess media and communication products from a sustainability perspective, social aspects should also be covered. The author participated in an international project group on social aspects and LCA, one outcome from which was guidelines for social LCA (S-LCA). In addition to providing guidance for S-LCA, another important role of the guidelines is to facilitate discussions, criticism and proposals for improvement and development of the methodology being developed.

The LCA and sector studies in this thesis are limited to direct and to some extent indirect environmental impacts. Further studies of the environmental impacts of more long-term changes in practices and potential structural changes, as well as potential social impacts, could provide important additional insights. This could increase the possibility of facilitating sustainable practices related to ICT and media.

Title

The guidelines for social life cycle assessment of products: just in time!

Published in

The International Journal of Life Cycle Assessment. Springer Berlin/Heidelberg 2010.

Abstract

Purpose Authors of different sustainability journals, including authors of articles in past issues of the International Journal of Life Cycle Assessment have acknowledged the rising interest and the pressing need for a social and socio-economic life cycle assessment methodology and identified challenges in its development and implementation. Social life cycle assessment (LCA) allows identification of key issues, assessing, and telling the story of social conditions in the production, use, and disposal of products. In this article, the United Nations Environment Programme/The Society of Environmental Toxicology and Chemistry Guidelines for Social Life Cycle Assessment of Products will be presented.

Aim and scope The guidelines demystifies the assessment of product life cycle social impacts and presents an effective framework representing the consensus of an international group of experts leading research in this field. The guidelines complement those for environmental life cycle assessment and life cycle costing, and by doing so contribute to the full assessment of goods and services within the context of sustainable development. They enable a larger group of stakeholders to engage. Key aspects of the framework and the research needs identified in the guidelines will be summarized.

Conclusions In a globalized world where transparency and information occupies a predominant place and where consumers and companies reach out to shed light on both the brightest and the darkest side of the economy and, when applicable, transform its condition, social LCA brings strong value. At a moment where major companies and initiatives are going forward with using LCA and are trying to track and communicate about the social impacts of their products they are increasingly held accountable for the guidelines for social life cycle assessment arrive just in time to inform their efforts.

Title

Lost in the supermarket: Mobile applications for sustainable food consumption

Published in

Master Degree Project at KTH, Media Technology (CSC), Stockholm, 2010.

Abstract

Food production and consumption has a major impact on the environment. In the last years the awareness of this issue has been growing both in the media and among consumers. Research shows that 25% of Swedes’ greenhouse gas emissions come from food consumption. This thesis is concerned with how mobile technology can help individuals to change to sustainable eating habits, specifically through persuasive applications. The research is focused around two prototypes: Fisk.cc, a seafood buying guide and Green Recipes, a mobile cookbook with sustainable recipes. The applications were developed and tested during the research. The thesis discusses the design of mobile applications for sustainable eating from three aspects: Social interaction design in persuasive applications, Motivating users to change behavior and Need for environmental data. The report concludes with four questions that serve as guidelines for development.

The study was undertaken for the Persuasive Services Project. David Kjelkerud was supervised by Marko Turpeinen and Jorge Zapico.

Title

Designing Mobile Persuasion: Using Pervasive Applications to Change Attitudes and Behaviors.

Published in

Sharing Experiences with Social Mobile Media. Proceedings of the International Workshop in conjunction with MobileHCI 2009, September 15th 2009, Bonn, Germany. Pp 11-16.

Abstract

We have a personal relationship with mobile phones, since they are closer to us than any other technological device. They are ubiquitous (60% of the world population owns one), individual, and pervasive in our lifestyle (we have them with us all the time and everywhere). These modern devices are nearly as powerful as personal computers, always connected to the Internet, and loaded with sensors like GPS and accelerometers. These mobile devices offer opportunities for persuading users to change attitudes and behaviors towards personal and societal issues. For this paper we focus on the design of a mobile application for reducing in carbon dioxide emissions in personal transportation choices that can change attitudes and behaviors. The paper presents design practices that have resulted in a prototype social mobile application.

Title

Using a life cycle perspective to assess potential social impacts of ICT services – a pre-study.

Abstract

Buying that new mobile phone may make your life easier, provide continuous access to the net and change your image, but what social impact will your action have on others? Different stakeholders along the life cycle of the mobile phone will be affected, in positive and negative ways. Who is responsible and how can we know the impact?

Handling environmental impact with a life cycle perspective, for example using life cycle assessment (LCA), is today common practice. A similar technique for social impact, social and socio-economic LCA (S-LCA) is under development (Benoit and Mazijn, 2009). The aim of the current pre-study was to consider the use of S-LCA for information and communication technology (ICT) services to learn more about the product and facilitate consideration of social impact in different decision-making situations.

From a company perspective, social responsibility is handled in various ways, often under the heading of CSR, corporate social responsibility. Firstly, the company’s own employees are easily targeted and acted on by providing good working conditions, fair wages and working hours, etc. Considering social impact throughout a product’s life cycle is the next step and here measures and responsibilities are less clear-cut.  How is a product distributed (supply chain), how is it used and how is it finally disposed? Different stakeholders are differently affected, positively and negatively.

Four companies and organisations, all partners in the Centre for Sustainable Communications, took part in this study. They currently have different experiences and degrees of activity regarding social responsibility. The telecommunications companies, Ericsson and TeliaSonera, have started to consider social aspects in their supply chain and for their consumers. Social aspects are not only considered in terms of impact of the company management but also of impact related to products (goods and services). The media organisations (Bonnier Group and the Swedish Media Association) have not handled social aspects to the same extent as the telecommunications companies, but of course their products also give rise to social impact throughout their life cycles.

To enable a discussion on the usability of S-LCA, a simplified test was carried out, inspired by the ongoing work on including social aspects into LCA within the UNEP-SETAC Life Cycle Initiative (Benoit and Mazijn, 2009). This screening test was based on a selection of published and readily available information on potential social impacts along the life cycle of two defined ICT services. The goal was not to provide an assessment of social impact, but rather to give a rough sketch and reflect on possibilities and limitations with the method. The two ICT services in the test were mobile news and video conferencing, provided by a newspaper company and a telecommunications company respectively. An interesting feature of both these services was that the company providing the service was not providing the electronic device, the hardware platform of the service. This gives one more dimension in the consideration of who is responsible for social impacts with a life cycle perspective.

There was a lot of information available on potential social impact for parts of the respective life cycles. This kind of information is gathered by scientists, NGOs and others. A small share of the information was compiled for the selected stakeholder groups: worker and consumer. This information indicated that there are social impacts all along the life cycle and that these may be positive or negative and of differing magnitude. As stakeholders become aware of the possible negative social impact, increasing engagement from organizations and companies in social responsibility will be requested.

When companies start to consider social impacts in the supply chain, it is expected to be easier to reach the first and second tier of suppliers. However, ILO (2007) has established that the workers at the beginning of the supply chain (farthest away from the end-product) are generally the most disadvantaged. In some cases, handling e-waste is also leading to major negative social impacts. Raw material acquisition and waste management may have large implications on the social impact related to a product, with best case or worst case possibly leading to significantly different results. A life cycle perspective would facilitate identification of improvement potential.  A key question is who is responsible, or rather who will accept responsibility.

As there is information available for parts of the processes and stakeholders throughout the life cycle of the ICT services studied, the question remains how this information can be used by companies providing products for end-consumers. This pre-study indicates that it can be useful to apply a life cycle perspective and compile data in relation to a specific product also when considering potential social impacts. This would facilitate the inclusion of processes and stakeholders for example at the beginning of the life cycle, where impact may be considerable and negative, and make these more visible. Development of S-LCA is thus interesting in order to provide transparent and ‘standardised’ assessments of potential social impact. By providing guidelines or standards, the assessments of social impact could be interpreted and criticised more easily. The possibilities for using S-LCA to increase knowledge and ultimately improve social conditions should be further studied and developed.

In the field of S-LCA there is plenty of future research to be carried out, examples of which are provided by Benoit and Mazijn (2009). One important way of getting more experience and enabling further development of the method and its practice is through performing case studies. ICT products would be an interesting field for this.

Title

Twenty thousand leagues under the sea: A life cycle assessment of fibre optic submarine cable systems.

Published in

Degree Project at KTH, Department of Urban Planning and Environment, Division of Environmental Strategies Research (fms), Stockholm, 2009.

Abstract

Submarine cables carry the vast majority of transcontinental voice and data traffic. The high capacity and bandwidth of these cables make it possible to transfer large amounts of data around the globe almost instantaneously. Yet, little is known about the potential environmental impacts of a submarine cable from a life cycle perspective. This study applies Life Cycle Assessment (LCA) methodology to collect and analyse the potential environmental impacts of a submarine cable system within a single consistent framework. The system boundary is drawn at the limits of the terminal station where the signal is transferred to, or from, the terrestrial network. All significant components and processes within the system boundary have been modelled to account for the flow of resources, energy, wastes and emissions. Data quality analysis is performed on certain variables to evaluate the effect of data uncertainties, data gaps and methodological choices. The results highlight those activities in the life cycle of a submarine cable that have the largest potential environmental impact; namely, electricity use at the terminal station and cable maintenance by purpose-built ship. For example, the results show that 7 grams of carbon dioxide equivalents (CO2 eq.) are potentially released for every ten thousand gigabit kilometres (10,000Gb/km), given current estimations of used capacity. The potential environmental impacts are directly linked to capacity and system usage, thus, increasing data traffic improves the environmental performance of the submarine cable system per unit of data. A focus area for further improvements is the emissions from ships, where the greatest gains in environmental performance are likely to be made through reduced emissions. This study is perhaps the first tentative step in linking together research into the environmental impact of terrestrial ICT networks.

The study was undertaken at Ericsson Research in Kista. Craig Donovan was suvervised by Åsa Moberg (Centre for Sustainable Communications) and Fredrik Jonsson (Ericsson).
