We’ve created the Sustainable Finance Guide to help lenders and borrowers better understand what makes a building truly sustainable. With buildings responsible for around 20% of New Zealand’s emissions, our guide outlines how certifications like Green Star, Homestar, and NABERSNZ can support green loans and bonds.
By using our rating tools, many in the property sector are already accessing better finance terms while cutting carbon. We’re also introducing pathways like a 30% emissions reduction target for NABERSNZ-rated buildings and recognising Homestar v5 under the Climate Bonds Standard—helping drive real change in how the sector finance the built environment.
