Carbon Footprint of an Internet Service Provider : Exploring the carbon reduction potentials of a residential router applying EcoDesign

Abstract: Global Warming is accelerated by human activity since the industrial revolution. We are currently experiencing the 4th industrial revolution with recent breakthroughs and rapid developments in digitalization, Industry 4.0 and Internet of Things (IoT). The environmental impact of the information and communication technology (ICT) industry will increase up to 3.9 % of the global environmental impact by 2030. At the same time, ICT products are able to avoid environmental impacts by almost ten times their impact. The ICT industry is undergoing a transformation influenced by scientific research and industry standards initiatives that support developments of European policies and directives, as well as increasing user demand for environmentally friendly products. As a consequence, companies are required to account and report environmental impacts along their value chain and reduce impacts by implementing environmentally conscious design such as EcoDesign.  However, integration among companies in the sector is insufficient. This is partly due to the complexity and lack of experience in accounting and reporting greenhouse gas emissions and implementing EcoDesign tools. Additionally, research on the life cycle environmental impacts of ICT companies and products is limited. Therefore, this study aims to minimize the gap between research and practice by assessing the carbon footprint of an Internet Service Provider (ISP), calculating the carbon footprint of a residential router from a life cycle perspective and exploring reduction potentials through the application of EcoDesign.  The assessment of the value chain carbon footprint of the ISP identifies that roughly 74 % is attributed to the so called indirect emissions (Scope 3), in particular category 3.11, the use of products. This is also reflected in the carbon footprint of the router. Since it is constantly in operation mode, the use phase causes up to 90 % of its carbon footprint. Different carbon footprint reduction scenarios are explored, showing that reductions are achieved through the use of new manufacturing methods, recycled materials, low-power technology, green electricity and changes in user behavior. It is concluded that EcoDesign is useful to reduce the carbon footprint of a residential router and Scope 3 of an ISP. Therefore, companies in the ICT industry that aim to reduce their carbon footprint are advised to use EcoDesign in combination with complementary environmental impact assessment tools.
