It employed the yield curve methodology proposed by Nelson Siegel Svensson. Statistical tests on greenium were also prepared. Daily data were collected from the Refinitiv Eikon database, covering the period from January 4, 2010, to October 17, 2024. The results suggest that greenium exists and is statistically significant. This phenomenon is noticed for the whole sample as well as the individual issuer and its bonds. The presented results show that greenium is negative and that it equals 9 basic point. The findings can be useful for regulators, governments, investors, and especially for financial institutions.
