Speaking at a State Street Global Advisors Green Bonds Summit in Boston, Climate Bonds Initiative Chair Sean Kidney announced that the Natural Resources Defence Council (NRDC) had joined the Governing Authority of the Climate Bonds Certification and Standards Scheme.
The Standards Scheme will help spur the growth of the global green bonds market by giving investors and governments an easy way to assess the integrity of environmental claims.
Mr Kidney said: "According to the International Energy Agency we need at least a trillion dollars a year to be flowing into low-carbon industries if we're to avert catastrophic climate change. That money will come largely from bond markets. We need to ensure it's invested properly."
