Valuing Green Infrastructure and Public Spaces
Virtual Event
Wednesday 27 October 2021
12:00 PM to 1:30 PM 

Free of charge

You will be able to access this event via a link sent to you the day prior.

Join us to hear leading subject matter experts discuss innovative valuation and policy approaches to valuing green infrastructure and public spaces.

Green infrastructure and quality public spaces are critical to a better living environment for everyone.

They are essential for liveability, and provide social, economic, environmental and cultural benefits to communities.

COVID-19 has demonstrated this further as people embrace the importance of walkable access to quality green and public spaces for supporting community resilience.

How do we quantify and monetise these assets in business cases and cost benefit analysis?

Hear from an expert panel on how we can better value and account for the benefits of green infrastructure and public spaces in long term government investment decision making now and into the future.

Our speakers:

Peter Colacino – Chief of Policy and Research, Infrastructure Australia
Kirsten Jensen – Principal Advisor, New Zealand Treasury
Cassandra Wilkinson – Executive Director Policy and Budgets, NSW Treasury
Dr Sorada Tapsuwan – Senior Research Scientist, CSIRO
Prof Thomas Astell-Burt – Professor of Population Health and Environmental Data Science, University of Wollongong
Dr Neil Perry – Senior Research Lecturer, Western Sydney University

The Department is developing a Sector Specific Framework that outlines best practice approaches to valuing these benefits to ensure our green and public spaces are consistently captured in policy and investment decisions.

This is a virtual roundtable event where academics and policy makers will explore innovative valuation and policy approaches being used in other jurisdictions to account for the benefits of these crucial assets.

This event is offered free of charge.


This is a unique opportunity for the whole sector to hear from leading experts in this space.

It will give participants insight into how economic policy, research and practice is evolving to create greener public spaces and cities.

If you are interested in environmental and social policy, planning, economics or simply ensuring that the places we live are greener, more sustainable, resilient and diverse, this event will inform and inspire you.
