Bloomberg Global Mayors Challenge

We have built a Digital Twin model of the city and we’ll be using our US$1million prize money to further develop its capabilities as an engagement tool to explore climate adaptation options with the community.

Snapshot from Wellington’s Digital Twin model

The purpose of this project is to further develop Wellington’s Digital Twin model to visualise climate change impacts and explore adaptation options with scientists, mana whenua and residents in an easily accessible, interactive gaming-style format for all to use.

Wellington’s Digital Twin will be an effective tool to engage and educate residents about localised climate impacts, and the complexity of adaptation such as storm surges and sea level rise.

"As a coastal city that is highly exposed to climate change impacts and with few options for relocating infrastructure, businesses and homes, it’s critical we enable evidence-based climate adaptation decisions in the next two to three years to respond to the climate and ecological emergencies declared by Council. We need new tools and engagement methods that allow everyone to understand the impacts, and to participate in co-creating a climate-resilient city."

The prize money of US$1million will be spent over three years (March 2022 – March 2025).


Bloomberg Philanthropies’ Mayors Challenge is a global competition designed to spark innovative ideas for improving cities, and the lives of people living in them.

This challenge was entered by over 600 cities worldwide and recognises the boldest and most ambitious urban innovations that address current issues including climate and the environment.

Only 15 cities worldwide were selected as overall winners and Wellington was the only New Zealand city to take out a top prize.
