    Green Bond Market Looks to Go From Billions to Trillions

    Green bond issuance in 2017 shattered the record from 2016, with both new and repeat issuers helping to satisfy the increasing demand for sustainable bond investments. Approximately $155 billion was issued by 242 issuers, including 156 first time green bond issuers. Total issuance was 84% higher than in 2016, an illustration of the spectacular growth that the market continues to experience.1

    New issuers bring diversity

    As the market’s size continues to increase, so does its diversity. The top three issuers were not only first time issuers, but also allowed investors to gain new types of exposure. Fannie Mae rocketed to the top of the issuance league tables with $24.9 billion of green asset-backed securities (ABS), backed by loans that finance either green multi-family housing, or energy, or water efficiency improvements. Although not new to the green bond market, Fannie Mae’s enhanced reporting and transparency allowed it to obtain the green designation from the Climate Bond Initiative2 in 2017. It should be noted, however, that although this designation makes the bonds eligible for inclusion in the S&P Green Bond Select Index, issuance was spread over more than 1,000 individual issues, none of which met the Index’s rigorous criteria on tradability and liquidity due to their issue size. Nevertheless, the growth of recognized green ABS issuance represents an important development and is an example of the opportunities that the securitization market can provide in addressing climate goals.

    France was the second largest issuer in 2017 with its benchmark sovereign green bond issuance. Although not the first ever sovereign green bond, it was by far the largest with over $10 billion issued in total, and helped pave the way for Fiji and Nigeria to come to market with sovereign green bonds later in the year. China Development Bank rounded out the top three issuers, with over $4.6 billion issued, including approximately $1.7 billion in EUR- and USD-denominated global issues. These bonds were “Certified Climate Bonds” and, therefore, satisfy rigorous pre- and post-issuance standards, and allow global investors to finance environmentally friendly “Belt and Road”3 projects related to energy, transportation, and water management.

    Despite the massive ABS issuance from Fannie Mae and a growing sovereign presence, non-financial corporates were the largest category of issuance in 2017. The largest corporate issue came from Mexico City Airport Trust, which issued $4 billion of secured green bonds to finance the city’s new international airport. The majority of corporate green bonds came from European issuers, with Apple rounding out the top 10 with a second green bond issuance that followed its landmark 2016 bond.

    The U.S. was the top country with $43 billion of green bond issuance, driven by Fannie Mae and municipal issuance. Corporate issuance in the U.S., however, continues to lag non-U.S. corporates. China and France were second and third highest in terms of issuer country, each with approximately $22 billion. Overall, Europe continues to dominate issuance, but the presence of an increasing number of emerging markets issuers may be a positive sign, given their need for green infrastructure.

    Bonds that finance projects focused on improving efficiency grew from 21% of the overall market in 2016 to 29% in 2017. However, energy-related projects (e.g., solar and wind projects) remained the most common from a use of proceeds perspective, with a 33% share of total issuance. Waste management and projects related to climate change adaptation accounted for 15% and 13% of total issuance, respectively.

    Once again, the amount of issuance carrying some type of independent verification increased, demonstrating the increasing importance that investors place on receiving some type of third-party review. 75% of total issuance in 2017 carried an independent review, versus an average of about 56% over the prior five years.

    2018 Outlook

    Issuance estimates for 2018 point to further growth. The Climate Bonds Initiative’s official estimate is for $250-300 billion of new green bonds. We expect the market to continue to diversify, and for a few key themes to emerge this year:


    1. Progress towards harmonized standards: Although it is unclear whether there will ever be, or needs to be, a single global standard for green bonds, progress is already being made to harmonize some of the local green bond standards and frameworks that exist. We believe that getting closer to a common standard could serve as a catalyst for further market growth.
    2. Better reporting: With the use of proceeds concept firmly established and generally accepted taxonomies in place, such as the one developed by the Climate Bonds Initiative, we believe investors will increasingly focus on the ongoing reporting by green bond issuers. Although the majority of issuers already provide some type of reporting, focus will likely shift to enhancing the level of information and providing standardized metrics. The 2017 updates to the Green Bond Principles4 (which were instrumental in catalyzing growth in the market when first created in 2014), puts increased emphasis on reporting metrics. We believe that better reporting will become commonplace, and perhaps even required, in the not too distant future.
    3. Using green bonds within SDG portfolios: The Sustainable Development Goals (SDGs) are 17 internationally agreed upon goals that seek, among other things, to protect the planet in an equitable way while maintaining and increasing prosperity. Institutional investors are increasingly constructing and evaluating portfolios through the lens of the SDGs by allocating capital towards investments which help to achieve these outcomes. Because of their positive impact, and the transparency provided through extensive disclosure, green bonds can be well suited for integration within SDG portfolios. We expect greater recognition and utilization of the SDGs by investors to promote growth of the green bond market.

    Billions to trillions

    Green bond market growth shows no signs of slowing following last year’s record issuance. In fact, out of all possible bond types, heads of debt capital markets at 20 of the top investment banks are most optimistic about green bond volume.5 However, at just ten years old, the market is still in its infancy and must grow dramatically in order to go from billions to trillions of U.S. dollars outstanding. Greater education is needed to bring into the fold fixed income investors who are not explicitly integrating ESG factors into their mandates. Increased demand will in turn encourage issuers who have so far stayed on the sidelines (with U.S. corporates the most glaring example) to jump in. With the ambitious goals of the Paris Agreement6 and the increasing awareness of the risks that climate change generally pose to sustainable development and within investor portfolios, we believe that issuers, investors, and policymakers all have a vested interest in growing the green bond market.
