The American Council on Renewable Energy's (ACORE) latest intern publication, titled Green Bond Market Insights—Why Corporates Matter analyzes exciting new developments in the green bond market and explains the increasing role that corporate issuers can play in its expansion. Written by summer 2016 intern, Patrick Eble, this publication comes at a time when total global debt issuance topped $4 trillion in 2015, of which only $42.4 billion (or 1.1%) were green bonds. Even more staggering are the figures for corporate green bond issuance in the United States, in which companies have issued $8 billion dollars of green bonds since 2013, a mere 0.15% of the country’s total corporate debt issuance over the same period. So how will the green bond market grow? Corporate issuance is crucial.
