Climate Change: the Contribution of Telecommunications

Global targets for reductions in green house gas emissions require that all economic sectors take stock and then act to limit and to reduce their contributions to climate change. Telecommunications is no exception and while it can help other sectors make savings, the expansion of and growing intensity of use greatly increases the attributable emissions. These arise from a wide range of inputs, including travel and transportation, energy to power and to cool equipment. While reporting at the level of corporations has improved, it is neither consistent nor complete. For consumers and businesses there are almost no data on the various services they buy that might inform their own decision making and their own reporting of emissions.climate change, energy efficiency, green house gases, telecommunications.

The EU Climate Policy after the Climate Package and Copenhagen - Promises and Limits. Egmont Paper No. 38, September 2010

This paper aims to provide a global assessment of the European Union’s climate change policy after the Climate Package and Copenhagen. In order to do so, the paper firstly describes the climate threats for Europe as well as the birth and objectives of the EU climate and energy package adopted in 2009. Then, the different components of this package are highlighted: the EU Emissions Trading Scheme (ETS), the obligations of the non-ETS sectors, the 20% renewable energy objective, the promotion of carbon capture and storage and the framework on environmental subsidies. Thirdly, the other EU climate policy legislations are examined, comprising: energy efficiency, the GHG emissions of cars, the GHG emissions of fuels, and the Strategic Energy Technology Plan (SET-Plan). Next, adaptation to climate change is discussed, before examining the international aspects of the EU actions after Copenhagen. As a way of conclusion, the paper assesses the EU climate policy throughout four main questions: What has the EU achieved until now? What will be the costs? What will be the impact on the European Union? And, is the EU action sufficient

Opportunities and Risks of Digitalization for Climate Protection in Switzerland

Information and Communication Technology (ICT) is an important enabler for a low-carbon economy in Switzerland. ICT has the potential to avoid up to 3.37 times more greenhouse gas (GHG) emissions than the amount of emissions caused by the production, operation and disposal of ICT devices and infrastructures used in Switzerland in 2025. In absolute terms, ICT will enable the Swiss economy to save up to 6.99 Mt CO2-equivalents (CO2e) per year, with an own carbon footprint of 2.08 Mt CO2e per year. This opportunity for the ICT sector to contribute to climate protection, however, can only be realized under optimistic assumptions. In particular, it is necessary that the existing technological and economic potentials are systematically exploited by taking ambitious and targeted actions. Such actions can be especially effective in the transportation, building and energy sectors, which have the highest potential for ICT-enabled (“smart”) solutions to reduce GHG emissions. At the same time, the carbon footprint of the ICT sector itself must be reduced by 17%, which is technologically and economically feasible due to efficiency gains

Challenges and complexities in application of LCA approaches in the case of ICT for a sustainable future

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 and water consumption. The need for specific representations and metric to separately assess products and technologies is discussed. It is highlighted that applying product-oriented approaches would result in abandoning or disfavoring of new technologies that could otherwise help toward a better world. Second, several believed-untouchable hot spots are highlighted to emphasize on their importance and footprint. The list includes, but not limited to, i) User Computer-Interfaces (UCIs), especially screens and displays, ii) Network-Computer Interlaces (NCIs), such as electronic and optical ports, and iii) electricity power interfaces. In addition, considering cross-regional social and economic impacts, and also taking into account the marketing nature of the need for many ICT's product and services in both forms of hardware and software, the complexity of End of Life (EoL) stage of ICT products, technologies, and services is explored. Finally, the impact of smart management and intelligence, and in general software, in ICT solutions and products is highlighted. In particular, it is observed that, even using the same technology, the significance of software could be highly variable depending on the level of intelligence and awareness deployed. With examples from an interconnected network of data centers managed using Dynamic Voltage and Frequency Scaling (DVFS) technology and smart cooling systems, it is shown that the unadjusted assessments could be highly uncertain, and even inconsistent, in calculating the management component's significance on the ICT impacts.Comment: 10 pages.

Mapping innovation in the European transport sector : An assessment of R&D efforts and priorities, institutional capacities, drivers and barriers to innovation

The present document provides an overview of the innovation capacity of the European transport sectors. The analysis addresses transport-related innovation from three different angles. It identifies the drivers and barriers to innovation for the main transport sub-sectors; it assesses quantitative indicators through the detailed analysis of the main industrial R&D investors and public R&D priorities in transport; and it identifies the key actors for transport research and knowledge flows between them in order to detect shortcomings in the current institutional set-up of transport innovation. The analysis finds that despite the significant on-going research efforts in transport, largely driven by the automotive industry, the potential for systemic innovations that go beyond modal boundaries and leave the currently pre-dominant design are under-exploited due to prominent lock-in effects caused by infrastructure and the institutional set-up of the innovation systemsJRC.J.1-Economics of Climate Change, Energy and Transpor

All you can stream: Investigating the role of user behavior for greenhouse gas intensity of video streaming

The information and communication technology sector reportedly has a relevant impact on the environment. Within this sector, video streaming has been identified as a major driver of CO2-emissions. To make streaming more sustainable, environmentally relevant factors must be identified on both the user and the provider side. Hence, environmental assessments, like life cycle assessments (LCA), need to broaden their perspective from a mere technological to one that includes user decisions and behavior. However, quantitative data on user behavior (e.g. streaming duration, choice of end device and resolution) are often lacking or difficult to integrate in LCA. Additionally, identifying relevant determinants of user behavior, such as the design of streaming platforms or user motivations, may help to design streaming services that keep environmental impact at a passable level. In order to carry out assessments in such a way, interdisciplinary collaboration is necessary. Therefore, this exploratory study combined LCA with an online survey (N= 91, 7 consecutive days of assessment). Based on this dataset the use phase of online video streaming was modeled. Additionally, factors such as sociodemographic, motivational and contextual determinants were measured. Results show that CO2-intensity of video streaming depends on several factors. It is shown that for climate intensity there is a factor 10 between choosing a smart TV and smartphone for video streaming. Furthermore, results show that some factors can be tackled from provider side to reduce overall energy demand at the user side; one of which is setting a low resolution as default.Comment: 7th International Conference on ICT for Sustainability (ICT4S
