En klimatanpassad järnväg : Långsiktig planering av infrastruktur i ett föränderligt klimat

Global warming is going to affect our society in many ways. One can say that the problem we face has two different sides. One of those sides has received a lot of attention, namely how we can reduce our emissions of greenhouse gases. However, because of the climate system's inertia the climate will continue to evolve over a period, no matter how much we will cut back on emissions. Because of this, we have to start adapting our society to the climate changes that we cannot influence. This side of the problem has been termed climate adaptation. Swedish society is, just like the rest of the world, faces major challenges in climate adaptation. An important part of the challenge is to protect the infrastructure. The Swedish Rail Administration’s (SRA) part of the challenge is to maintain a functioning rail system, regardless of how the environment around the railway is changing. By taking account of climate change when planning for new rail, future problems can be avoided. This report investigated what SRA can do to create a climate adapted railway. Within the scope of this report, useful information is identified and a working model for how this information can be used when planning new railways is suggested. The model is then evaluated in a case study and the results are presented. The goal is that the work will provide a wide basis for every day work on climate adaptation within Banverket
