      abstract = {Having started the phasing-out of nuclear process,  Switzerland will have to face the challenge of replacing  nearly 30% of its domestic power generation in the medium  run. Currently, imports from the European Union are used  when indigenous production is unable to meet demand.  However, growing import dependency in winter represents not  only a potential threat to the security of supply but also  electricity import with a heavy GHG content. The  development of decentralized power generation through  natural gas-fired combined heat and power (CHP) plants  could be a short-medium run solution allowing to produce  electricity on the Swiss territory during winter. In this  work, we evaluate how the replacement of a part of the  inflows from neighbouring countries by decentralized CHP  plants fueled by natural gas impacts the hourly carbon  footprint of the electricity consumed in Switzerland. We  developed a four-step methodology to answer this question.  Firstly, we assess, for the years 2016 to 2019, the GHG  content of the electricity consumed in Switzerland in  accordance with the consumption principle and applying the  attributional Life Cycle Analysis (LCA) approach. Secondly,  based on natural gas delivery data, we modelled hourly gas  consumption for heating purposes by means of the heating  degree-hour method. Then, based on the previous part, we  simulated hourly electricity production with natural gas  CHP plants. Finally, we assessed the hourly GHG emission  from electricity consumption with the new solution. The  results show that, actually, imports impact strongly and  negatively the GHG footprint of the electricity consumed in  Switzerland. The results of the last part show that the  development of decentralized power generation through  natural gas-fired CHP plants can lower the GHG footprint of  the electricity consumed in Switzerland. Indeed, in nearly  all the scenarios, the naturalgas CHP solution is a  less-GHG-emitting alternative to imports.},
