ICT for Sustainable Last-Mile Logistics: Data, People and Parcels
We finish by discussing key opportunities for intervention and further research in ICT4S and co-created Smart Cities, connecting our findings with existing research and data as a call to the ICT4S community to help tackle the growth in carbon emissions, pollution and congestion linked to parcel deliveries.

The Material Footprint of the ICT and E&M Sectors
Abstract: This paper explores different life cycle based material footprints for the ICT and E&M sectors. The basic material footprint is defined by mass. In this study a large number of materials (mainly metals) were studied and results indicate that the ICT and E&M sectors uses about 0.5% of these selected materials. The material carbon footprint for the ICT and E&M sectors – the carbon footprint of the raw materials acquistion and EoLT stages – is found to be about 0.9% of the selected materials carbon footprint, and about 0.1% of the total global carbon footprint. The material footprint defined as the material resource depletion potential was estimated to be between 13% and 49% of the global material resource depletion potential depending on methodology. Finally, a material toxicity potential footprint was estimated based on ReCiPe to about 4% of the global toxicity potential related to the selected materials and global cement production. Overall the reults indicate that the ICT and E&M sectors are important from a resource and toxicity potential. The recycling scenario plays a crucial role for all results. In this study a current scenario with low recycling rate was assumed, and the results may improve considerably with increased recycling.

Energy Consumption of Mobile Data Transfer – Increasing or Decreasing? Challenges in Evaluating the Combined Impact of Technology Development & User Behavior
Abstract: Mobile data consumption in Finland is among the highest in the world. Increase in mobile data usage has been rapid and continuous growth is foreseen. While the energy consumed per transmitted gigabyte has substantially decreased, it seems that the absolute annual energy consumption related to mobile operators’ activities has started to increase. Simultaneously, consumer behaviour is changing. While new end-user devices are more and more energy-efficient, we use more and more time with mobile devices. Is increasing usage outweighing achieved energy savings? What kinds of options are available for tackling increasing energy demand? This paper discusses current and future trends related to energy consumption of mobile data transfer and mobile networks in Finland. Using a top-down approach and publicly available data, an illustrative trend (kWh/gigabyte) for the energy consumption of transmitted mobile data was constructed for the years 2010-2016. In addition, energy consumption related to mobile data transfer is discussed from a life cycle perspective, considering both direct and indirect energy use and challenges in conducting such assessments. Contributions of relevant technological and social developments (radio network technology transformations from 4G to 5G and consumer behavior) are analyzed considering possible trade-offs and pointing out aspects that require future studies.

An Empirical Evaluation of Database Software Features on Energy Consumption
Abstract: Although software does not consume energy by itself, its characteristics determine which hardware resources are made available and how much energy is used. Therefore, energy efficiency of software products has become a popular agenda for both industry and academia in recent years. Designing such software is now a core initiative of software development companies aiming toward social responsibility. Meanwhile, however, developing environmentally sustainable software products is a challenge in that performance, functionality and energy consumption can reflect conflicting goals. In this paper, our objective is to analyze the effects of different features on energy consumption of the IBM DB2, a commonly used database product. The empirical work focuses on three features. We executed a workload in preconfigured software with some features enabled or disabled and with different numbers of users. To compare the different scenarios, three sets of green metrics were utilized. The metric set identified various parts of the software system where energy is consumed. Our findings may suggest that the conflicts among software system performance, functionality, and energy consumption can be mitigated by choosing a combination of features that interact in a way that improves energy efficiency.
