Japan’s Government Pension Investment Fund will begin significantly increasing their investments in green bonds next year, Nikkei has reported. The GPIF, which is Japan’s largest public investor by assets managing 159 trillion yen ($1.5 trillion), will from October solicit green-bond indexes from financial index companies. According to the Climate Bonds Initiative, the global issuance of green bonds amounted to $167.6 billion in fiscal 2018. Without a linked index, Japan issued $5 billion worth of these bonds.
