High speed rail at SETAC & NorLCA symposium

MiSA presented method, results and reception based on the recently completed Norwegian high speed rail assessment at the LCA case studies symposium in Copenhagen 26-28 November.

The paper High speed rail in Norway: method, results and reception in use of LCA for policy analysis was presented by Johan Berg Pettersen.

The results of the Norwegian high speed rail assessment are available here. There where corridors that paid back in terms of greenhouse gas emissions within the 60 year assessment period.

The general reception of the assessment is that most stakeholders consider high speed rail a commuter system. Market and economy are most promising for high speed as an extensio of the InterCity rail network South (South West) of Oslo, even if the assessment shows this not to reduce greenhouse gas emissions.

The paper also tested some concept improvements. one improvement is to have a less stringent speed requirement, allowing a more flexible alignment and thus less tunnels on the line (based on crude internal estimates). A second improvement is better adaptedcapacity and seat occupancy, thereby reducing electricity used in operation. The net efffect of these measures is for the Numedal route N1:Q Bergen-Oslo a reduction in GHG pay back period from 47 to 39 years.

The full presentation is available below. See also the conference website.
