Syftet med rapporten är att undersöka och analysera motiv och ekonomiska incitament bakom fastighetssektorns deltagande på den gröna obligationsmarknaden i Sverige. Rapporten diskuterar huruvida en grön premie eller ett Green bond premium, även kallat Greenium, existerar samt hur stort detta är. Greenium är skillnaden mellan räntan på en grön obligation och en traditionell obligation. Vidare analyseras anledningar till att ett Greenium skulle uppstå. En diskussion förs huruvida det är mer ekonomiskt lönsamt att köpa gröna obligationer i jämförelse med traditionella obligationer. År 2007 utfärdade Världsbanken den första gröna obligationen i världen i samarbete med SEB. Sedan gröna obligationens uppkomst har marknaden vuxit till ett globalt värde på över 300 miljarder dollar. Vasakronan utfärdade världens första gröna företagsobligation 2013, efter det fick marknaden i Sverige sitt största uppsving och sedan dess har marknaden vuxit kraftigt. Gröna obligationer har samma ekonomiska egenskaper som traditionella obligationer men skillnaden är att intäkterna från gröna obligationer måste finansiera miljö- eller klimatvänliga projekt. Gröna obligationer medför en del risker för aktiva aktörer. Dessa risker är bland annat anseenderisk, greenwashing och asymmetrisk information. Med tanke på den enorma påverkan företag idag har på miljön är det lämpligt att dessa tar ansvar för sina utsläpp och andra negativa externa effekter. Genom konceptet Corporate Social Responsibility har företag tagit mer ansvar för hur de påverkar samhället ur såväl ett ekonomiskt, miljömässigt samt socialt perspektiv. Genom CSR har gröna obligationer blivit populärt och i synnerhet på fastighetsmarknaden där ambitionen kring hållbarhet vuxit kraftigt de senare åren. Sammanfattningsvis kan det konstateras att ett greenium finns men att det är svåruppskattat. Enligt intervjuade personer inom fastighetsbranschen kan greenium antas vara -4 till -5 baspunkter och enligt vetenskapliga artiklar antas det vara cirka -2 baspunkter. En baspunkt motsvarar en hundradels procent. Att greenium uppstår beror på investerares stora efterfrågan och emittenters låga utbud på gröna obligationer i dagsläget. Fastighetsbranschen är ledande på den gröna obligationsmarknaden i Sverige och detta antas bero på branschens tidiga modifiering av gröna obligationer samt sektorns välutvecklade certifieringssystem av hållbara byggnader. I framtiden kan den gröna obligationsmarknaden antas växa och utvecklas inom såväl andra branscher som andra länder. / This report aim to examine and analyze motives and financial incentives behind the real estate sector's participation on the green bond market in Sweden. The report discusses whether a Green bond premium, also called Greenium, exists and how large it is. Furthermore, the reasons why a Greenium can occur are analyzed. A discussion about whether it is more economically viable to trade in green bonds compared to ordinary corporate bonds is implemented. In 2007, the World Bank issued the first green bond in the world in cooperation with SEB. Since then the market has grown to a global value over $ 300 billion. Vasakronan issued the world’s first green corporate bond in 2013 and since then the green bond market in Sweden has grown strongly. Green bonds have the same economic traits as traditional bonds, but the difference is that revenues from green bonds must finance environment or climatefriendly projects. Green bonds entail some risks for active issuers and investors. These risks include reputation risk, greenwashing and asymmetric information. Given the enormous impact companies have on the environment, it is appropriate for companies to take responsibility for their emissions and other negative external effects. Through the concept Corporate Social Responsibility companies have taken more responsibility for how they affect society from both an economic, environmental and social perspective. Through CSR green bonds have become popular and especially on the real estate market, where the ambition of sustainability has grown strongly in recent years. In conclusion, it can be stated that a greenium exists but that it is difficult to estimate. According to interviewed issuers in the real estate sector, greenium can be assumed to be -4 to -5 basis points and, according to scientific articles, it is assumed to be about -2 basis points. The fact that greenium arises depends on investors’ large demand and issuers' low supply of green bonds at present time. The real estate industry is the leading sector in the green bond market in Sweden and this is assumed to be due to the industry's early modification of green bonds and the sector's well-developed certification system of sustainable buildings. In the future, the green bond market can be assumed to grow and develop in both other industries and other countrie

In this thesis the existence of the yield premium of green bonds is investigated. This paper complies with the instructions that were used in the analysis run by Zerbib(2018). The results of the fixed-effect panel regression confirm the hyphotesis on which our paper is based on. We found a nagative premium: the yield of the conventional bond is higher than the yield of the green bond. Furthermore, this paper examines how the defintion of the greenness of the bond is specified by various institutions and experts.

This thesis examined the effect of non-financial motives, namely pro-environmental or sustainability preference, in bond pricing on the European secondary market before and during the COVID-19 crisis over the period 02.01.2019-26.02.2021. To estimate the potential yield spread between green bonds and matched conventional bonds, we applied a stringent matching method and fixed-effect regression to explore the green bond premium. The result indicated a small positive premium of 0.46 bps before the COVID-19 (01.2019-02.2020) and a small negative premium of 0.2 bps during the ongoing COVID-19 crisis (03.2020-02.2021), and the premiums have significantly changed between the two study periods, implying that the COVID-19 had a significant effect on the GB premium. Thus, before the pandemic, investors demanded compensation in the form of a higher yield return on investing in green bonds; however, during the pandemic, investors are willing to accept a lower yield on the GBs in comparison to the equivalent CB to finance environmentally-friendly projects. Additionally, the paper investigated bond volatility by analyzing the standard deviation of the daily yield. Although green bonds tended to have a higher volatility, no robust conclusion could be drawn due to a lack of statistical significance.

The green bond market offers investors the opportunity to take an explicit focus on sustainable investment projects. However, it is yet to be determined whether this novel asset class offers attractive yields compared to non-green bonds. To address this question, we study European green bonds and how they diverge from conventional bonds in terms of yields. Using a dataset of 88 matched pairs of European green bonds between 2015 and 2019, we document a significant negative green bond premium of -12 bps on average in the secondary market. The green bond premium is defined as the yield differential between a green and a conventional bond while controlling for liquidity. The results suggest that European investors accept a lower financial return in exchange for receiving non-pecuniary benefits and thus challenging the assumptions of classical asset pricing models. Furthermore, we use a matching method and two-step regression to control for liquidity and identify the determinants of the green bond premium. The results show that the negative green bond premium is less pronounced for lower-rated bonds. Moreover, we find support for variations in the green bond premium across different business sectors. Government-related green bonds experience a greater negative green bond premium than green bonds related to financials and industrial corporates.
