BlackRock has announced the launch of the iShares Global Aggregate Bond ESG UCITS ETF following increased demand from investors to incorporate ESG into their fixed income portfolios. The fund, which tracks the Bloomberg MSCI Global Aggregate Sustainable and Green Bond SRI Index, offers broad, diversified exposure to the global bond market across 70 countries and over 30 currencies. The index adopts a best-in-class approach including a series of ESG and business involvement screens as well as excluding issuers with an MSCI ESG rating lower than BBB. It also aims to achieve a measurable environmental impact by allocating at least 10% of its market value to green bonds. "As the shift to sustainable investing continues to accelerate, we have seen strong demand, from across client segments – for a sustainable global aggregate exposure," said Brett Olson, Head of Fixed Income iShares in EMEA for BlackRock.
