Cloud Computing is often regarded as form of "green computing". However, the growth of cloud computing also goes hand in hand with an increasing demand for energy, caused by a continuously growing demand for content, data-intensive applications and bandwidth. The debates on the energy implications of...

This paper explores how companies and other stakeholders could assess the macro-level enabling potential of Information and Communication Technologies (ICT), in other words, the ability of ICT to reduce the negative sustainability impact of other industry sectors at a society level, and identifies some...

Modern hardware devices that are idle for a certain period of time enter into sleep mode as a means of reducing power consumption. Naturally, devices should remain in sleep mode for as long as possible to maximize energy savings. However, a growing number of applications perform non-urgent background...

Mobile technology offers great opportunities for renewing corporations’ sustainability agenda. In particular, the positive impact can be increased and new segments of people can be engaged. Gaming for Good is an area that combines the most popular mobile applications, games, with sustainability ingredients....

Recently, data centres have been called out for their particularly high energy consumption, which already accounts for 1.5% of the total global electricity consumption and is among the world’s fastest growing energy consumptions. To reduce the data centres’ environmental impacts, technologies such as...

The information and communications technologies (ICT) sector is seeking to reduce the electricity consumption of data processing centres. Among the initiatives to improve energy efficiency is the shift to cloud computing technology. Thanks to very favourable geographical conditions, the Canadian energy...

Energy and environmental sustainability can benefit a lot from advances in data mining and machine learning techniques. However, those advances rely on the availability of relevant datasets required to develop, improve and validate new techniques. Only recently the first datasets were made publicly available...

ICT is known to have three orders of impact: direct, indirect and systemic. The first is often regarded as 'part of the problem', the latter two can also be 'part of the solution' to reduce the global environmental impact of human activities. A number of studies show that the impact of ICT itself is...

Though rapid increase in energy consumption has become a global problem, most of the solutions developed to address it for residential consumers are based on qualitative studies conducted with small numbers of users, typically in the developed world. Recent work has begun to explore consumption practices,...

Assessments of digital services wishing to take into account an energy footprint of the Internet typically require models of the energy intensity of the Internet. A common approach to the modeling of the energy intensity is to combine estimates of market surveys of installed network devices on a national...

Sustainability research about using Information and Communications Technologies (ICTs) to reduce household energy consumption has recently focused on two potential strategies: “smart homes” that rely on sensors and technological innovations to automatically reduce the energy load, and tools that seek...

In this work, three of many ICT-specific challenges of LCA are discussed. First, the inconsistency versus uncertainty is reviewed with regard to the meta-technological nature of ICT. As an example, the semiconductor technologies are used to highlight the complexities especially with respect to energy...

In the paper a concept of an ICT system for complex management of whole city is presented. The ICT system called Smart City consist of several branch modules integrated by a GIS platform. The system is being developed by the Systems Research Institute (IBS PAN) in Warsaw in cooperation with Intergraph...

How could use of ICTs make transport systems in large cities sustainable To what degree would then everyday patterns of action, in which use of ICT is becoming increasingly integrated, be an effective force in such sustainable development In this paper we use own and other ethnographic studies of how...

Recent years have seen a rapid growth of ICT-services related to the transportation area, and for example Advanced Travel Information Services (ATIS) have been proposed as one means to achieve a decrease of environmental impacts of transportation through behavioural change. However, empirical studies...

The mobile phone market is constantly evolving. Retailers and manufacturers offer a larger number of features to customers: a mobile network more and more efficient (2G, 3G then 4G), handsets with computer features, navigation, gaming, etc. This progress involves the use of more efficient and reduced...

We present the design and evaluation of the heat recovery system for KTH’s Lindgren, Stockholm’s fastest supercomputer, a Cray XE6. Lindgren came into service in 2010 and has since been primarily used for complex numeric simulations of fluid mechanics and computational chemistry and biology. The heat...

The widespread adoption of cloud computing is having a big impact on the environment since the energy consumption of data centers and the resulting emissions are significantly increasing. Researchers and practitioners in this field are looking for methods to improve the energy efficiency of data centers...

In this paper we present the findings of an in-depth consultation with 50 experts in Agriculture and ICT. The qualitative study explored how ICTs, particularly mobile phones, could be used to accelerate the uptake of Sustainable Agriculture in Africa. Situating the responses in a broad literature review,...

Sustainability management systems are important technologies used by large organisations to monitor and control their CO2 emissions and other environmental impacts. So far, these systems have been designed to support data collection and reporting mandated by regulations, but they provide little support...

This paper explores whether it is useful to view the fundamental ideas behind the smart city concept through the lens of the ‘Public Value Management’ (PVM) paradigm. It investigates how appropriate ICT investment in cities might be articulated and valued through the concept of PVM. In order to achieve...

This paper presents preliminary findings from a big data analysis and GIS to identify the efficiency of waste management and transportation in the City of Stockholm. The aim of this paper is to identify inefficiencies in waste collection routes in the city of Stockholm, and to suggest potential improvements....
