NZ Taxonomy -
Energy

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.

In partnership with the New Zealand Government, CSF is working to support New Zealand’s transition to a resilient, low emissions economy, by creating a sustainable finance taxonomy (the NZ Taxonomy).
