Are green investment funds really that bad compared to conventional funds?

This thesis aims to provide an answer whether green investment or conventional investment Funds outperform the other in terms of risk-adjusted returns. The measures employed include the Treynor ratio, the Sharpe ratio and the Jensen's alpha. The technique employed uses a matched-pair approach over a ten-year period, to identify statistically significant out/-underperformance. The results provide mixed indications for which type of fund outperforms. Even though, some risk-adjusted-performance medians where differing, the majority of those measures did not differ to a statistically significant degree. However, green funds tend to be less exposed to market-risk, but bear higher fund specific-risk, compared to conventional funds.
