About the toolkit

This online toolkit provides people with information about different climate change scenarios and the impact they may have.

Purpose of the toolkit

The primary purpose of this toolkit is to support central government agencies with accessing relevant climate scenarios information to test policies and decision making.  

Other entities, such as local government and the private sector, may find aspects of the tool useful, but are not the intended audience for this toolkit.  

Limitations of this toolkit

Not for mandatory climate reporting entities

This toolkit is not for entities that prepare mandatory climate-related disclosures under the Financial Sector (Climate-related Disclosures and Other Matters) Amendment Act in alignment with the External Reporting Board’s (XRB) New Zealand’s Climate-Related Disclosure Standards

If you are a mandatory reporting entity, XRB - Aotearoa New Zealand climate standards has more information about climate scenarios and scenario analysis.

Non-reporting entities may find sector scenarios (or elements of the scenarios) useful for testing policies and strategies.

Non-reporting entities should keep in mind that some aspects of the reports accompanying sector scenarios may not be relevant where they concern XRB Climate-Related Disclosure Standard requirements.

Limitations of using existing climate scenarios

Using a set of existing scenarios has limitations. Each set of existing scenarios was developed by various organisations for a wide variety of different purposes, using different methodologies and assumptions.

Read more about the limitations of existing scenarios in The Emperor’s New Climate Scenarios report [Institute and Faculty of Actuaries]

It is important to consider whether the existing set of scenarios you choose is sufficiently relevant for your purposes. You may choose to alter existing scenario assumptions, provided you do so in a transparent manner.
