Abstract

Sustainable development requires the decoupling of economic growth from environmental impacts and from the use of natural resources. This article gives an overview of existing approaches to using Information and Communication Technology (ICT) in the service of sustainability: Environmental Informatics, Green ICT, and Sustainable Human-Computer Interaction (HCI).

FAQs

sparkles

AI

What demonstrates the potential of ICT in achieving sustainability goals?add

The paper highlights ICT's role in implementing decoupling strategies, suggesting it fosters a less material-intensive economy. For instance, it discusses how software-based value creation can support resource decoupling.

How have resource decoupling and impact decoupling progressed historically?add

Since the 1970s, GDP growth has outpaced resource extraction, indicating limited resource decoupling. Recent UNEP reports emphasize the need for impactful decoupling to align economic growth with sustainability.

What challenges arise regarding the recycling of ICT hardware?add

Complex material composition in ICT hardware hinders efficient recycling, with up to 60 elements in modern microprocessors. This complexity has escalated recycling difficulties, leading to resource dissipation if not recovered.

How does the Jevons Paradox apply to energy efficiency in ICT?add

The Jevons Paradox illustrates that increased operational efficiency can lead to higher overall resource consumption, as seen in the rapidly growing electricity use for computing. Between 1980 and 2008, computing power doubled every 1.5 years, resulting in increased total energy demand.

What insights does Sustainable Human-Computer Interaction provide for technology design?add

Sustainable HCI emphasizes designing technologies that support sustainable behaviors throughout their life cycles. Research by Blevis in 2007 underscored the importance of integrating sustainability as a primary design criterion in technology development.

ICT for Sustainable Development
Dr. B. Charles Henry

The use of ICT to drive sustainable development is a constant debate. Whereas one group staunchly defends emp loying ICT for guiding and implementing sustainable development, others fight vigorously to highlight its many negatives. One should readily agree that, as with most things in this world, apply ing ICT to propel any development will have its benefits and pitfalls. Its measurement must therefore be focused on whether the advantages outweigh the disadvantages. I will argue that driving sustainable development through ICT initiat ives bring much greater benefits than negative consequence. One is also acknowledging that like all good projects, protocols and methods are impo rtant to success. Therefore, when advancing sustainable development with ICT as the driv ing force, it is essential to have proper planning, analysis, implementation, and mon itoring if one anticipates favorable outcomes. I will build upon this argument in more details in the ensuing sections.

ICT and sustainable development
Eman Gamal

What Kind of Information Society? Governance, …, 2010

We discuss various views and conceptual frameworks put forward in the discussion of ICT and sustainable development: An optimistic and a pessimistic view of ICT with regard to sustainability, the three-pillar approach to sustainable development, the three-level approach to ICT impacts, the claim of human, social and ecological compatibility of ICT and the plain use of ICT for development. We show that each of these approaches has its problems and limitations and conclude with formulating the challenges of finding an analytical approach which will effectively support decision-makers in using ICT in the service of sustainable development.

An international Master's program in green ICT as a contribution to sustainable development
Alexandra Klimova

Journal of Cleaner Production, 2016

Various principles of sustainable development are currently being integrated into national policies and programs. Such principles relate to a range of aspects of human activities requiring urgent attention, including heating, mobility, food security, and sustainable agriculture. One of the fields contributing to the transition towards a sustainable society is that of green information and communication technologies (ICT). Therefore, the implementation of educational programs in green ICT is important in ensuring further ICT development around sustainability concerns. This article describes the development of an international Master's degree program named "Pervasive computing and communications for sustainable development" (PERCCOM) by an international consortium, which aimed to combine advanced ICT with environmental, economic, and social awareness. The article presents background information regarding the role of the ICT sector in environmental challenges, and a review of the literature, in order to understand what is required of ICT and green ICT graduates. The curriculum of the PERCCOM program is then described and findings on program improvement are reported. The article is aimed at academic and research professionals in the fields of sustainable development and green technologies, with the goal of improving educational initiatives to address the societal demand for sustainable development. The findings reported here contribute toward the search for a solution for sustainability, especially regarding environmental issues, among educating professionals with high expertise in networking, computing, and programming, who are able to design, develop, deploy, and maintain both pervasive computing systems and communication architectures for sustainable development.

Utilisation of Information and Communication Technology for Environmental Sustainability: A Global Perspective
Cedric Owuru

2021

There has been a rapid development of Information and Communication Technologies (ICTs) globally, and ICT have been used as a tool to attain environment sustainability all over the world. There are diverse environmental challenges faced by developing countries such as ecosystem deterioration, pollution, resource depletion, loss of biodiversity and climate change and the management of above problems is difficult because they involve multiple actors and its occurrence is over time and space. Environmental Scientists have raised concerns on how these environmental challenges can be tackled bringing into lamplight, how ICT and environmental science research can be used to wedge these challenges in developing countries. The study is exploratory and employed the use of survey questionnaires as an instrument to collect data. Findings revealed that a lot needs to be done for ICT to be effectively used in the environment, factors such as inadequate facilities, problem of acceptance and adapt...

The Future Impact of ICTs on Environmental Sustainability
Lorenz Hilty

2004

"Information and Communication Technologies (ICTs) not only constitute an industry in their own right but they also pervade all sectors of the economy, where they act as integrating and enabling technologies. ICTs have a profound impact on society, and their production and use have important consequences for development in economic, social and environmental areas. The extent to which ICTs also affect progress towards environmental sustainability in an economy is an issue that is still under debate. There is, however, increasing evidence that significant opportunities and threats are involved. These deserve more research and more attention in energy, climate change and technology policies. The Institute for Prospective Technological Studies (part of the Joint Research Centre - European Commission) has commissioned a study entitled ‘The Future Impact of ICTs on Environmental Sustainability’, which aims to explore (qualitatively) and to assess (quantitatively) the way that ICTs will influence environmental sustainability between now and 2020. This study is the first quantitative projection to be carried out on how ICTs could affect the environment in the European Union. In order to estimate the effects of ICTs on a set of five environmental indicators, the project team adopted an innovative methodology combining qualitative scenario-building and quantitative modelling. The general conclusion was that ICTs can modify the value of these five indicators. ICTs could improve the situation, reinforcing positive effects in the environment, or they could worsen the situation. This suggests that environmental policies have to be designed to ensure that ICT applications make a beneficial contribution to environmental outcomes, and, at the same time, suppress rebound effects. There are significant opportunities for improving environmental sustainability through ICTs, which can rationalise energy management in housing (or facilities), make passenger and freight transport more efficient, and enable a product-to-service shift across the economy."

ICT for Sustainability : Proceedings of the First International Conference on Information and Communication Technologies for Sustainability
Lorenz Hilty

Our world is getting smarter: smart homes, smart cities, smart grids, smart vehicles and logistics, cloud computing, crowdsourcing. Many smart solutions are today designed in a “Green IT” context and proposed with the intention to contribute to environmental or social sustainability. Such claims include, for example, reducing greenhouse gas emissions, saving energy, finding the most sustainable alternative in a decision situation, optimising a process with regard to sustainability criteria, or enabling participation and reducing poverty. However, it is difficult to determine whether the potential net benefit of the smart solution will materialize under real-world conditions, in particular when considering the dynamics of markets, possible rebound effects and other systemic effects. "Smarter" does not necessarily imply "more sustainable". The First International Conference of Information and Communication Technologies for Sustainability (ICT4S), held in Zurich on ...

INNOVATIVE GREEN ICT FOR ENVIRONMENTAL SUSTAINABILITY
IJRCAR JOURNAL

IJRCAR, 2015

Environmental pollution is one of the serious problems faced by the people most of the countries of the world. Especially in the urban areas, those are characterized by rapid growth of population due to high fertility, low mortality and increasing rural-urban migration and industrialization. It is preferable to prevent environmental damage from occurring in the first place, rather than attempting to restore degraded environmental resources and it is not possible without environmental awareness. This paper is based on an empirical survey, was undertaken to compare the environmental awareness of male, female and science, commerce and arts teachers of higher education in Bhopal, M.P., India and also to study the role of Information and Communication Technology (ICT) in increasing level of environmental awareness. ICT is an environmentally friendly technology, which conserves natural resources and the environment. It can improve environmental performance and address climate change across the economy. ICT innovation is a key element to spur green growth in the economic crisis and recovery. The green ICT has diverse benefits that can create substantial value. It is the present & as well as future of the society. Its main goal is to find ways to produce technology in ways that do not damage or deplete the Earth's natural resources and help to increase the awareness for environment.

ICT for Sustainability – Current and future research directions
Beth Karlin

This workshop brings together researchers from the entire iSchools community to propose, share and discuss their current research and future research agendas and foster collaborations on ICT for Sustainability. Sustainability as a research focus has inspired the creation of a number of workshops and conferences, including the International Conference on ICT for Sustainability (http://www.ict4s.org). ICT plays a major role in sustainability. It threatens sustainability as ICT devices cause carbon emissions, produce e-waste, but it can also be an enabler of sustainability [4], in form of systems that support the protection of natural resources, and that foster social sustainability, in the form of systems that foster communities and participation [8, 5]. These supporting systems come from many intellectual traditions within and beyond the information field (e.g., requirements engineering [9], software quality [10], life cycle analysis [6]) and design (e.g., sustainable HCI [1, 11]). As information scholars, we have a responsibility to work to ensure the survival of life on this planet, including humans as well as other rational agents, namely animals [2]. Sustainability is thus a critical value for ICT researchers to embrace and strive toward [3, 7, 12]. The iSchools community provides an excellent place to discuss this crucial topic at the intersection of information, society, and technology. This workshop will bring together scholars from across the information field studying ICT for sustainability, to foster new interdisciplinary and multidisciplinary collaborations. 2 Proposed Format The workshop is planned as a full day workshop. We will solicit abstracts, papers, and/or position statements, and will set up easychair for managing submissions. Participant registration will be managed through the conference registration site. We will start the morning with a series of short presentations by the authors, each of them followed by a brief discussion. The audience will be engaged by guiding questions from the moderators to spark discussion. We will wrap up the morning session by summarizing the talks and connecting them to identify common topic areas and future research needs. For the afternoon sessions, we envision a series of breakout sessions that discuss selected common topic areas and future research needs. These breakout sessions shall facilitate the design of a future research agenda as well as the development of new research collaborations between the participants. The results from the breakout sessions will be reported back in a plenary wrap up session that outlines possible next Abstract This workshop brings together researchers from the entire iSchools community to propose, share and discuss their current research and future research agendas and foster collaborations on ICT for Sustainability.

Green ICT Applications towards the Achievement of Sustainable Development
Maro Vlachopoulou

E-Innovation for Sustainable Development of Rural Resources During Global Economic Crisis, 2014

"Green ICT" constitutes a new term in Informatics that describes environmentally sustainable ICT and the use of ICTs in the interest of the natural environment aiming to sustainable development. It encompasses innovative ICT tools, e-and m-services, and smart technologies in combination with green practices and green behaviour either for the ICT industrial sector or the ICT user/citizen that contributes not only to the protection and restoration of the environment but also to the enhancement of the quality of human life. Thus, "Green ICT" has become synonymous with eco-friendly technologies and software tools.

Information and Communication Technologies (ICTs) and Environment Sustainable Development -an Integrated Approach
Paraskevi Mentzelou

Information and Communication Technologies (ICTs) is the combination of hardware, software and services for capture, process, transmit and for displaying data and information electronically. Sustainable development is the development that fulfils the current needs without setting in danger the next generations' needs fulfilment. At a first glance, ICTs and environment sustainable development seems to be two sectors that look extrinsic but the impact of ICTs in the environment is widely accepted by the scientific community and frequently is taken for granted. In the scientific community there is a strong belief that these two sectors are correlated but still there are many uncertainties on where the border lines between these two scientific sectors lay. Clear quantified evidence has not been found yet despite the extensive research based on the link of ICTs and successful environment sustainable development. This study deals with the impact of ICTs on environment sustainable development and is based on the unique characteristics of ICTs and their concrete contribution to environmental sustainability. A general approach is taken by categorizing ICTs in three main domains: a) ICTs advances and development; b) Green ICTs and c) ICTs for the environment and the positive and negative affects of each category are presented.

The Role of Information and Communications Technology (ICT) In Environmental Sustainability
IOSR Journals

IOSR Journals , 2019

ICTs play a key role in the protection and sustainability of the environment. This paper provides an overview on how ICT can help tackle environmental challenges. It also examines the benefits of ICT in the environment and how ICT investments can help guide in setting policy that will promote societal sustainability. The paper further addresses effects of ICT on sustainability in the areas of education, energy, environment, and transportation. It observes that ICT can improve transportation via the use of smart meters to monitor traffic (resulting in congestion pricing) and make energy delivery and consumption more efficient with the use of smart thermostats. Tele-and video-conferencing can reduce travel needs, leading to reduced carbon emissions for the environment. Distance and online learning technologies can reduce the need for brick and mortar buildings as well as the need for transportation in delivering education. Finally, telemedicine, ehealth, and m-health have the potential to make delivery of public health more efficient. Adoption and proper utilisation of ICT thus have the potential to promote sustainability within the society at large.
