Conclusion

  Indication that high emission levels are negatively associated with market evaluations

  Financial markets: seem to consider climate change as a business relevant factor

  Strategic management: proactively reducing a firm’s carbon dependency is important

  Next steps:   increase transparency about GHG emissions to foster these

developments   broaden awareness of climate-finance link to accelerate carbon

sensitivity of capital markets
