HOW TO READ THIS REPORT
From this research, we have developed this report to
offer decision-makers and in?uencers a ‘ready reckoner’
for net zero buildings in 2024. This report includes
signposts for board and c-suite leaders thinking about
the next round of investments and organisational
strategy, because when it comes to technology and
climate change, success requires them to look through
the windscreen rather than the rearview mirror.
We include suggestions for how board directors
and business leaders can act now, plan their next
move, and what to watch for on the horizon. We also
provide insights to give property leaders a deeper
understanding of the challenges facing corporate
tenants and opportunities to address the asymmetries
to secure a new competitive advantage.
We also spoke with policymakers, ?nanciers, technology
specialists and engineers. And we drew on EY’s
international network of experts, to develop a technology
readiness roadmap.
We applied the Green Building Council of Australia’s Climate
Positive Roadmap
4
to the technologies to frame the
discussions and determine the most practical technologies
for large-scale deployment. This Climate Positive Roadmap
sets a clear direction of travel: all new buildings and ?touts
in Australia must be net zero in operation by 2030, with
existing buildings and ?touts to follow by 2050 (Exhibit 4).
Many CEOs and C-suite leaders have a burning question in
the back of their minds: How do we create value from ESG
and the net zero transition?
In this report, we present some of the opportunities and
unpack the obstacles that CEOs and C-suite leaders will
encounter as they answer this question.
This report aims to provide a clear overview of the big
picture of net zero buildings. We recognise that readers
will have varying levels of subject familiarity and need for
detail, so we start each section with the key points so you
can read this document in less than ?ve minutes. Deeper
dives can be taken in the areas of interest to you.
To inform this report, we surveyed and spoke to board
directors, business leaders, and heads of sustainability.
This gave us insights into a wide range of perspectives
on the current state and potential future evolution of the
commercial property sector, and views on priorities for
action. We report qualitative and quantitative ?ndings for
two key groups:
• Executives who lead and oversee some of Australia’s
largest corporate tenancies, who we refer to as ‘corporate
leaders’ in this report.
• Executives from some of Australia’s largest property
development companies and asset owners, most of them
in executive sustainability roles, whom we refer to as
‘property sustainability leaders’.
Other nations are investing trillions into smart energy-
saving technology, precinct-wide energy generation and
other leading-edge solutions. To understand this and the
opportunities for Australia, we talked to both domestic and
international leaders.
