A sustainable finance taxonomy is a classification system. It labels and establishes credible criteria for economic activities based on their contributions to meeting environmental goals.
Our long-term prosperity and resilience depend on transitioning to a low-emissions economy. The NZ Taxonomy creates a common language between investors and businesses and intends to flow capital to activities which support the transition, by making it easier to assess the sustainability credentials of an activity or investment, thereby lowering associated costs and greenwashing risk. For businesses, the NZ Taxonomy can be used to distinguish activities that could be relevant for a broader range of financing structures offered by lenders or investors.
The TAG is responsible for providing technical input to inform taxonomy definitions for Technical Expert Group (TEG) endorsement, and for offering feedback on TEG technical methodologies for TEG’s consideration and approval.
The TAG’s key responsibilities include identifying and proposing a list of construction and buildings sector activities and measures, and associated criteria for climate change mitigation, adaptation, and resilience.
