SBB’s green framework contributes to major reductions of carbon dioxide emissions through energy efficient buildings. SBB’s green framework is in line with the so-called Green Bond Principles, which have been developed by the International Capital Market Association (ICMA). SBB has commissioned and received an independent valuation from CICERO, Center for International Climate Research, in Oslo of the green framework and associated steering documents and routines for assessing the environmental impact of the projects. In light of their assessment of project type, steering documents goals and reporting standards, SBB’s green framework has received a Medium Green assessment by CICERO.

SBB has also received a Green Evaluation with score E2 from Standard & Poor’s (S&P) in connection with SBB’s debut green bond in the capital market in February 2019. E2 is the second highest score and SBBs green framework receives a strong score for governance and an excellent score for transparency, whilst at the same time the total score is negatively affected by the fact that Sweden, compared to other countries, has a higher share of renewable energy in its energy mix. The rating scale goes from E1 to E4 and is based on three criteria; transparency, governance and mitigation.
