Understanding risk and informing decisions
A theme in much of the evidence received during this inquiry is the need
to ensure decision-makers at all levels, ranging from individual property
owners to governments, have access to the reliable information necessary to
make informed decisions about managing climate risks. Furthermore, it is
reasoned that collecting and publicising further information about climate
risks will facilitate more timely action that will reduce the costs which will inevitably
be faced in the future. For example, the Investor Group on Climate Change
The longer Australia waits to implement effective adaptation
planning and infrastructure solutions the more expensive it will become to
adapt. Currently the economic costs are not being adequately assessed or
When considering the implications of climate change for infrastructure,
it was also emphasised that there are unique considerations. These relate to
the interconnectivities and interdependencies between different types of infrastructure
assets and the significant flow on effects associated with disruption. For
example, as Dr Lauren Rickards observed in her submission, 'transportation
services cannot operate without energy'. Dr Rickards argued that infrastructure
networks 'with critical interdependencies are at an increased risk of failure
from external shocks or stresses', and that it is important 'to understand the
extent of interdependencies and climate related risks faced by infrastructure
systems so that adaptation solutions can be developed or tailored accordingly'.
Ms Emma Herd, Chief Executive Officer, IGCC, provided similar
observations about the interdependences between business assets and essential
utilities and transportation networks. Ms Herd commented:
This question of interdependency is so key in terms of
effective adaptation and resilience planning. For a lot of businesses, their
key physical climate change risk may not be in the asset that they have direct
control over. When I say 'key climate change risk', I mean their financial
impact might be in an associated value chain or supply chain area. For example,
if you're a data centre and you're in an area subject to heatwave conditions,
your biggest vulnerability is in the resilience of the electricity network. If
you think that through, if you're a financial institution which has data
centres concentrated in areas of increased heatwave conditions, potentially one
of the banks' biggest vulnerabilities in terms of physical risk is in the
resilience of their data centre. Alternatively, if you're a property asset, you
may have invested significantly in resilience measures on site, but in fact
your biggest physical risk is then associated with the arterial roads to get to
your asset, public transport infrastructure to bring your employees in, or
precinct-level measures to protect from increased flooding or inundation if
you're in a coastal area.
This chapter considers the evidence received about how decision-makers
could be better informed, such as by conducting analysis that considers worst-case
climate projections, identifying the most at-risk infrastructure, undertaking
further research and through the public disclosure of climate risks.
Planning for worst-case scenarios
The previous chapter summarised some of the climate change projections
currently utilised by Australia's key research institutions and government
agencies. The analysis and emissions pathways framework developed by the Intergovernmental
Panel on Climate Change (IPCC) was also briefly outlined.
These projections are based on scientific data and rigorous analysis,
however, they reflect scientific understanding at a point in time. Advances in
scientific understanding of changes in the climate system have been achieved,
yet knowledge gaps remain. Future emissions levels also cannot be predicted with
There is some concern that the existing approach to developing climate
projections is overly conservative. The Breakthrough National Centre for
Climate Restoration (Breakthrough) argued that IPCC assessments have taken an
excessively cautious approach to climate change projections and have 'underplayed
high-end possibilities'. Breakthrough partly attributed this to the consensus
approach taken to compiling the IPCC's reports, which it argued results in
insufficient attention being given to low‑probability, high-impact risks
that are 'greater than we would expect under typical statistical assumptions'.
Breakthrough presented several arguments as to why it considers the global
climate models are deficient. One of the reasons is that the models do not
adequately account for carbon cycle feedback.
Another is that the rate of polar ice‑mass loss is underestimated. Alternative
studies were cited indicating that, even if just the Antarctic ice sheets are
considered, there is the potential for multi-metre sea level rises this century
rather than the up to 1.5 metre average rise referred to in Chapter 2.
Professor Ross Garnaut AO, who in 2007 was appointed to undertake a
comprehensive climate change review by the state and territory governments, and
then the Australian Government, has also discussed the potential for climate
risks to be understated. In a 2011 paper, Professor Garnaut commented that
there is a possibility of such an outcome due to scholarly reticence and
publications lags, with the pattern of increasing concerns in the scientific
community about climate risks supporting this conclusion. Professor Garnaut
It is remarkable that the review of developments in the
science—new observations and results of new research—have all either confirmed
established scientific wisdom, or shifted the established wisdom in the
direction of greater concern. This continues a pattern that has been present
for some time. As noted earlier in this paper, the fourth assessment by the
IPCC embodied more concern than the third, the third than the second and the
second than the first.
Professor Garnaut argued that the possibility of risks being understated
is 'not a reason to clutch for knowledge outside the mainstream wisdom';
he emphasised that 'if our discussion ceases to be grounded in the established
science, we have no firm, common ground from which to work on the most difficult
policy problem of our times'. However, the professor concluded that when
considering measures for climate change mitigation and adaptation, there is
likely merit in taking stronger action. Professor Garnaut concluded:
We should...be alert to the possibility that the reputable
science in future will suggest that it is in Australians' and humanity's
interests to take much stronger and much more urgent action on climate change
than might seem warranted from today's peer-reviewed published literature. We
have to be ready to adjust expectations and policy in response to changes in
the wisdom from the mainstream science.
Given the possibility of climate projections being overly cautious, Breakthrough
argued that a prudent risk management approach requires 'a tough and objective
look at the real risks to which we are exposed'. Breakthrough added that there
is a particular need to consider:
...those high-end events whose consequences may be damaging
beyond quantification, and which human civilization as we know it would be
lucky to survive. It is important to understand the potential of, and plan for,
the worst that can happen, and be pleasantly surprised if it doesn't. Focusing
on "middle of the road" outcomes, and ignoring the high-end
possibilities, may result in an unexpected catastrophic event that we could and
should have seen coming.
Dr Craig James from CSIRO suggested that there is a problem with people
becoming 'relaxed' about climate change reaching a certain level, such as the
consequences of the world warming by a global average of 2°C. Dr James remarked
that this is 'a dangerous space to be in, quite frankly'. Dr James noted that a
global average increase of 2°C presents significant problems for all nature-based
systems and that there is 'a lot of necessary adaptation between here and two
degrees, let alone anything beyond that'.
The committee also received evidence indicating that the private sector
does not comprehend the risk climate change presents to their activities. Mr
Andrew Petersen, Chief Executive Officer, Sustainable Business Australia,
provided the following comments about this:
Warren Buffett, that well-known raconteur, has built a
fortune on that interface between risk and reward. One of his most famous
quotes was that risk comes from not knowing what you are doing. The evidence
suggests, from the private sector at least, that it doesn't actually fully
understand the complexity of the risks that it faces and therefore does not
know yet how to respond. A recent review of corporate disclosure reports
revealed that 72 per cent of suppliers say that climate risk could
actually significantly impact their business operations through revenue or
expenditure yet only half of those are currently managing that risk.
Assessment of existing and emerging risks to infrastructure
To help understand the implications of climate change and to enable
decision‑makers to focus on the most at-risk infrastructure assets, it
was suggested that a national assessment or audit of existing infrastructure
could be undertaken. Essentially, the evidence received identified two areas in
which a national study could add value:
- by calculating the overall total anticipated cost of climate
change and the investment in adaptation measures that will be required; and
by identifying the most at-risk assets to enable adaptation
responses to be prioritised.
A vocal advocate for undertaking a national assessment of the
anticipated cost of climate change and the necessary investment in adaptation
measures is the IGCC. Ms Emma Herd, Chief Executive Officer of the IGCC,
explained that despite climate change already affecting infrastructure and
resulting in additional costs for business and government, 'no comprehensive
estimate seems to exist on the cost of climate change impacts on Australia and
the likely level of investment required for adaptation measures'. Ms Herd noted
that an accurate understanding of the potential exposure of investments to
climate risks and the ways in which business assets can be managed to reduce
exposure are key concerns for investors. Ms Herd explained, however, that the
absence of comprehensive information about the overall risk 'makes cost benefit
analysis of climate change adaptation at an aggregated level impossible to
Ms Herd provided the following further comments in support of developing
rigorous estimates about the costs associated with implementing the adaptation
measures that are likely required:
No matter which way you look at it, climate change has a
cost. So, the question then becomes: do you want to invest in mitigation to
reduce the absolute cost of adaptation, or do you want to defer investment in
mitigation and just pay the bill for adaptation on the other side? And at the
moment we're having a policy discussion whereby we're calculating only half of
that equation, which is the cost of mitigation. We're not actually calculating
the full cost–benefit analysis of climate change for Australia, which is: which
side of that ledger will we pay more on, and where do we get the most economic
benefit in terms of increasing our investment?
Ms Herd continued:
...the Paris Agreement sets out quite ambitious goals of
limiting global warming to two degrees or less—we're not currently anywhere
near meeting two degrees. At best, we're at 2.6, but that's if everybody does
everything that they currently say they're going to do. We're more likely,
currently, to hit three-plus. That has huge cost implications for Australia,
and we don't know what the bill is for that current projected change. We don't
even know what the bill is for two degrees of change at the moment. So, it
definitely feels as though we're having a policy discussion with only half the
information we need, and part of the need for that national assessment of value
at risk is the need to have a fully informed public policy discussion.
Ms Herd added that businesses are undertaking assessments to understand
the potential consequences for their assets; however, they 'have to pay an
awful lot of money for it...and it's not publicly available and it's not added up
at a national level to give a view of the macroeconomic impacts'. Accordingly,
Ms Herd argued there is a preference for a whole-of-economy approach to
obtaining this information.
Professor Lesley Hughes from the Climate Council of Australia similarly drew
the committee's attention to the absence of an up-to-date national assessment
of climate change risks.
The Queensland Tourism Industry Council argued that a risk assessment to examine
the overall consequences of climate change should be undertaken that considers
the 'costs for defending buildings and infrastructure, environmental issues,
and associated socio-economic benefits'.
Others focused on how a national audit could inform the prioritisation
of adaptation work by identifying the assets most at-risk from climate change.
The Australian Sustainable Built Environment Council (ASBEC) submitted:
There would be great benefit in a comprehensive national
audit project to identify the core assumptions and technical parameters used in
the design and delivery of infrastructure. This should fundamentally inquire as
to whether climate change predictions have been incorporated into these
During the inquiry, the committee sought details about the information
currently available to government about the climate risks to infrastructure.
Dr Russell Wise from CSIRO explained that the National
Exposure Information System (NEXIS) operated by Geoscience Australia
provides 'a reasonably good understanding of current infrastructure and their
exposure to coastal inundation'. However, Dr Wise acknowledged that further
work would be useful. In particular, Dr Wise observed that scenarios
regarding socio-economic development (such as population size and the location
of infrastructure assets in the future) are not as advanced as climate change
Other CSIRO representatives similarly agreed that a national audit of at-risk
infrastructure would be of value to assist further research and planning about
climate change adaptation.
In considering a national assessment, it is evident that the scale of
the task could potentially be overwhelming. For example, CSIRO's evidence
suggested that studies of infrastructure would identify that 'enormous numbers
of houses and dollar values of structures are going to be affected'.
The IGCC acknowledged that a national assessment of adaptation costs would
be 'complicated'. To approach it successfully, the IGCC suggested it could be
undertaken as part of each IPCC cycle; that is, after the IPCC's work has been
undertaken and peer-reviewed, a national study could be undertaken with private
sector participants to take the IPCC's analysis 'down to the level where it's
investable and workable and plannable'.
Ms Herd referred the committee to New Zealand where a regularly updated report
on projected climate change implications is prepared on a cyclical basis
alongside the IPCC's work cycle. Ms Herd added that this report is supplemented
by other reports focusing on specific risks, such as the implications for coastal
infrastructure, natural capital reserves, forestry and the agriculture sector.
Ms Kirsty Kelly from the ASBEC suggested that a national assessment of
at-risk infrastructure would not need to involve testing assets. Rather, the
assessment could add value by reviewing the standards applied in the
construction of those assets and considering 'whether those standards are based
on the frequency and intensity of weather events that we are seeing now'.
International approaches to undertaking national risk assessments could
be instructive. Recently, researchers have considered how an appropriate
framework for undertaking a national assessment of climate risks to
infrastructure could be developed for the United Kingdom. In a paper published
in April 2018, they argued that due to the interconnectivities and
interdependencies of infrastructure sectors, 'collective consideration' of the
multiple infrastructure sectors is warranted. The paper identified the
following approach for undertaking a national assessment to prioritise
A starting point will be agreement of a common baseline, some
standardized socio-economic and adaptation scenarios to provide common
reference points (but not limit development of other scenarios), and improved
records and metadata about adaptation actions. However, to fully tackle the
issues...a national capability needs to go further and must ultimately provide a
common and internally coherent analytical framework that enables different
risks to be fairly compared. It must be able to analyse the impact of 'persistent'
events (e.g. repeated sequence of storms or floods, in the same or multiple
locations) and simultaneous hazards (e.g. wind storm coupled with flooding).
This can only be achieved by producing a national database of the location,
function, design and condition of assets, and a record of any adaptation to
these assets in order to provide a reliable assessment of current and future
Research and data
Stakeholders generally agreed that a key role for government,
particularly the Australian Government, is to ensure that adequate and reliable
data, analysis and guidance is available to guide responsible decision-making.
For example, the Climate Council of Australia submitted that:
In order to climate proof infrastructure, the design,
building, financing and maintenance of infrastructure must use the best
available climate science and adaptation information available from premier
agencies such as CSIRO and [the Bureau of Meteorology].
Generally, comments from local governments and other stakeholders about
the need to be informed about how they can adapt to climate change called for
information to be updated more regularly, widely disseminated and publicised,
and utilised consistently by all levels of government. For example, Hobsons Bay
City Council submitted:
To effectively plan for and manage extreme weather events,
climate projections are needed that are based on the best available science and
are relevant to the local area. This information should be widely disseminated
and readily accessible to inform emergency management planning. It should
also inform minimum legislative standards and planning decisions to ensure
houses, buildings and infrastructure are designed and built to reduce the risk
to human life and wellbeing.
Corporate Australia also uses data collected by Australian Government
agencies to guide decision-making. Wesfarmers explained that it uses CSIRO data
to inform climate resilience planning and to improve its 'understanding of the
material climate change issues that face our divisions', including physical,
regulatory, reputational and competitive risks.
Sydney Airport referred to its participation in workshops presented by the
Australian Climate Change Adaptation Research Network for Settlements and
Infrastructure (ACCARNSI), which is hosted by the National Climate Change
Adaptation Research Facility (NCCARF) and funded by the Australian Government.
Mr Andrew Petersen, Chief Executive Officer, Sustainable Business
Australia, emphasised there is a need for the Australian Government to provide
ongoing financial support for research institutions, as well as sharing of the
data collected to assist companies and governments to make decisions about the
need for, and location of, future infrastructure. Mr Peterson argued that continually
collecting data and maintaining datasets and making them available to all
decision-makers in the economy would help build 'resilience into our economic
This section examines government support for climate research generally.
This is followed by a discussion of the evidence from stakeholders that called
for research to be used to develop specific products to assist with planning or
for existing guidelines to be updated more frequently. This discussion is based
on the evidence received during this inquiry. Relevantly, however, the
Australian Research Council (ARC) recently provided funding for a new centre
for excellence relating to climate change. The ARC Centre for Excellence for
Climate Extremes at the University of New South Wales opened in April 2018.
As this occurred after submissions to this inquiry were received, the evidence
outlined below does not consider this development.
Australian Government support for the
National Climate Change Adaptation Research Facility
Submitters highlighted changes made by the Australian Government to the
funding of climate change research. In particular, submitters referred to
funding reductions for the NCCARF at Griffith University.
The NCCARF was established by the Australian Government and commenced
operating in 2008. Since it was created, the Australian Government has provided
$56 million in funding.
However, based on current funding announcements, from 2018–19 the Australian
Government will not be directly funding the NCCARF.
Submitters commended the work undertaken by the NCCARF and other research
organisations such as CSIRO that provided resources to assist communities,
businesses and governments to adapt to climate change effectively. For example,
Mr Andrew Petersen, Chief Executive Officer, Sustainable Business Australia,
commented that, over the last decade, this work has been 'instrumental to a
number of businesses' in various sectors, including finance, insurance,
infrastructure and construction.
The Local Government Association of Queensland (LGAQ) also highlighted
the importance of the work undertaken by the NCCARF. It submitted:
While the Climate Council and a few other not for profit
organisations undertake pieces of research and prepare publications about the
implications of climate change on the matters of concern to this inquiry, there
is currently only one organisation, the...NCCARF...that provides peer reviewed and
credible synthesis of research outcomes specifically for practitioners.
This service is vitally important to facilitating the uptake
of leading thinking by time poor practitioners who are not climate change
specialists, but have content expertise e.g. coastal engineers, urban and
regional planners and policy and regulation makers.
The Australian Coastal Councils Association (ACCA) and Professor Lesley
Hughes from the Climate Council of Australia called on the Government to
provide further funding to support the NCCARF and for funding for climate
change adaption generally to be stable and ongoing.
Sydney Airport also submitted that it would 'encourage the ongoing work' of
ACCARNSI and the NCCARF.
The ACCA focused on the CoastAdapt tool to illustrate the importance of
the work undertaken by the NCCARF and the need for the Australian Government to
provide the NCCARF with ongoing funding. The Association submitted:
The cut in funding means that NCCARF will be unable to
continue its adaptation research activities including research to further
develop the CoastAdapt web tool, which was launched in September 2016 to assist
coastal councils respond to rising sea levels and other climate impacts.
The CoastAdapt web tool quickly became established as a vital
source of information and guidance for coastal councils attempting to minimise
the impacts of a changing climate on their local communities and environment.
The decision to cut funding for climate adaptation research was a major
disappointment to coastal councils and other agencies attempting to deal with
the imminent threat of a changing climate.
The LGAQ expressed concern that the CoastAdapt could become obsolete
without ongoing funding to maintain and update the tool. The LGAQ called on the
Government to provide funding to maintain the tool and to expand it to include
modules on bushfire, heatwave and flooding.
Australian Rainfall and Runoff
Concerns were expressed about the approach taken to updating the Australian
Rainfall and Runoff guideline (ARR). The ARR is prepared by Geoscience
Australia and is used by designers and engineers 'for the estimation of design
flood characteristics in Australia'.
The ARR was first published in 1987 and was not updated until 2016.
While submitters welcomed the 2016 update, there was general concern about
the time that elapsed between updates, particularly as climate change was not
considered in the original version. For example, a joint submission from a
group of engineers and scientists stated:
The 1987 edition of ARR did not address potential impacts of
climate change at all, so approaches to incorporating climate change prior to
the release of the 2016 edition of ARR varied considerably between studies,
where climate change was considered at all.
To help ensure that infrastructure can be designed to be resilient to
the effects of climate change, Consult Australia called for the Australian
Government to ensure that Geoscience Australia has adequate resources to update
documents such as the ARR more regularly.
Consult Australia also suggested that resources should be made available to
Geoscience Australia and other relevant bodies to develop material similar to
the ARR for other climate-related matters, such as temperature, wind and
Mapping and other datasets of
High-level projections and simulations of flooding and coastal
inundation were identified in Chapter 2. Other examples of tools developed to
assist local governments to gain a more detailed understanding of the
interactions between flooding and different management measures were provided,
including a tool developed by CSIRO to assist local governments located along
the Port Phillip coastline.
Floodplain Management Australia (FMA) highlighted the importance of
useful flood risk information compiled by a respected source for informed
decision‑making. The FMA submitted:
Having access to flood risk information underpins effective
flood management and our ability to reduce the flood vulnerability of
communities. Educating and engaging the broader community on their
vulnerability to the impact of flooding and other natural hazards is also
essential to building resilience. FMA supports transparency and education
around flood risk.
Mapping information is also valuable for the insurance sector.
Overall, it was acknowledged that governments have undertaken work to
gather data and to ensure that relevant data are available to businesses and
It was also noted that large amounts of data have already been collected. Given
this, Ms Megan Motto from Consult Australia indicated that there is a need
to identify 'what we need, how to make use of it, how to make sense of it [and]
how to analyse it in a way that's useful for us in designing the buildings and
roads and rail of the future'.
However, local governments and other owners of infrastructure need more
detailed and tailored information to consider and plan for risks. For example,
the committee was advised that the publication of risk mapping at a local level
would help inform decision-making. By ensuring reliable information was freely
available, it was suggested that governments could then require investors to
take responsibility for any subsequent decisions to build in at-risk areas,
enabling future governments to resist future pressure for resources to protect
CSIRO submitted that there is 'insufficient data for sophisticated urban
modelling', and suggested that there 'may be benefits from having standardised
nationwide high-resolution information, including tide, rainfall and terrain
Dr Russell Wise from CSIRO advised that Emergency Management Australia is
'exploring the development of a national capability on disaster risk
information to understand what's required now and into the future and the
changing nature of the natural hazards that will be causing disasters'. Dr Wise
suggested that this work, which is focused on natural hazards, 'could be much
more broadly applied to other forms of the more insidious chronic changes
caused by climate change'.
Hobsons Bay City Council submitted that, in its view, at present there
is 'a significant gap in information available for coastal planning and
sea level rise'. The Council detailed its concerns and suggestions for
improvement as follows:
The national first pass assessment of sea level rise is at a
high resolution with limited usefulness for land use planning. Effective
mapping that shows likely sea level rises over a range of time periods is
needed at a scale that can inform land use decisions. It is most effective to
undertake this mapping at a federal or state level due to the scale of the
problem and to ensure a consistent approach between regional agencies and
include local councils.
Mapping should be refreshed at regular intervals (e.g. every
decade) and incorporate the latest scientific information. Mapping should
clearly communicate the probability of the risk occurring in a way that is
clear to the community. For example: 'based on the best available science at
the time there is a 10 per cent chance that sea level rise will be less than
this and a 90 per cent chance it will be greater than this.' Such an approach
will enable the community to understand the risk and will limit the temptation
for modelling to be based on lower level risks due to political pressure.
Hobsons Bay City Council advised that the continued funding of key projects,
such as the CSIRO modelling of coastal and land-based flooding around Port
Phillip referred to in paragraph 3.41, 'is a priority to coastal communities'.
Similarly, Lake Macquarie City Council called on the Australian Government
to continue to invest in science that contributes to improved climate change
projections regarding sea level rises and associated coastal hazards'.
It was also suggested that existing work undertaken to better understand the
effects of climate change in particular regions should be better publicised.
The Climate and Health Alliance also urged increased 'investment in
vulnerability mapping programs to identify and map vulnerable populations and
infrastructure to inform climate adaptation strategies and emergency response
In addition to calls for continued investment in risk mapping, including
the development of more detailed maps tailored to particular regions, broader
concerns about the need for coordination and government leadership were put
forward. The FMA argued for the development of a national approach to how
information about flood risk associated with climate change should be prepared
and published. The FMA argued that a national approach would be useful to
overcome resistance in some locations about how the public release of such
information could affect property values. The FMA explained:
We acknowledge that many of our Local Government members face
political and public pressure due to perceptions—warranted or otherwise—about
the impact of releasing flood risk information about property values,
development opportunities and insurance premiums. A national approach to how
climate change flood risk information should be prepared and publicly
disseminated, and how such information should be applied in the planning of
existing and new areas, would go a long way to diffusing parochial reluctance
in dealing with the issue.
Ms Megan Motto, Chief Executive Officer, Consult Australia, commented
that there are also issues with the interoperability of the systems that store
Although several stakeholders commented on the value of information being
make public, it was argued that enhancements to how public information is released
are also necessary in some instances to maximise the utility of the information.
For example, Mr Mark Leplastrier, Senior Manager, Natural Perils, IAG,
referred to the Australian Tropical Cyclone Database managed by the Bureau of
Meteorology. Mr Leplastrier commented:
Every man and his dog is basically picking up that dataset
and trying to make sense of it to understand cyclone risk. If we could put much
more scientific effort into establishing a much better source of truth there,
we'll start being able to have aligned views of risk and what to do about it.
Mr Leplastrier added, however, that Geoscience Australia is developing a
Tropical Cyclone Risk Model (TCRM) that is 'basically digesting historical
cyclone tracks' and has the ability to produce a risk model that could be used
in insurance or planning. Mr Leplastrier explained that a key feature of the
TCRM is that it has been set up to enable researchers to 'contribute to the
model and improve on it'. Mr Leplastrier observed that this model:
...might be an interesting thing to take forward, if we can
actually really focus scientific attention into that model. It's a bit like a
local government flood study, which is a very good set of scientific
information. If we could do that with these other important hazards and then
have that available for people like insurers or engineers to pick up, that
would be very, very good.
Mr Neil Plummer from the Bureau of Meteorology commented that, although
there is 'a lot of data and information available with which to make better
decisions...there is a need for more accessible, nationally integrated datasets'.
Despite it being acknowledged that governments understand the need for publicly
available data, there are apparent issues with proprietary data. Mr Karl
Sullivan from the Insurance Council of Australia explained that the insurance
sector has struggled to access certain datasets at a reasonable price. Mr
There are a number of datasets, even some residual flood
datasets, where we are still negotiating, after a decade, to try to obtain
those datasets at a reasonable cost and reasonable price, considering that
anything you purchase has to be passed on to your customers at some point.
Mr Dwayne Honor from the FMA noted that it is difficult to get
information from all infrastructure asset owners that is needed to 'understand
the interconnected nature of our critical infrastructure', such as the
information held by local governments and telecommunications providers. Mr
Honor explained that the information can be obtained, but 'sometimes it is not
an easy process'. Mr Honor continued:
It depends on the resources of the other asset owners, and
then whether they want to share it with you. Some of them are pseudo-private
organisations and aren't as willing to share information as government agencies
can be. Oftentimes it is just ignored because it is too hard to get the
Mr Honor suggested that a protocol could be developed to which relevant
organisations could sign up that would enable information sharing and address
concerns about sensitive information being disclosed.
Mr Sullivan emphasised that the public release of previously
cost-prohibitive datasets in the past has also resulted in beneficial and
innovative outcomes. Mr Sullivan noted that the release of the geocoded
national address file, which previously cost around $20,000 a year for each
individual licence, resulted in 'a huge amount of innovation not just from the
insurance industry, who were suddenly able to access it more freely, but from
small start-up companies, innovators and app developers'.
Ms Megan Motto, Chief Executive Officer, Consult Australia, also noted
that there is an issue with data being 'held in disparate locations and places
and by different authorities', such as local, state and the Australian
governments, as well as private businesses. Ms Motto noted that this issue is
receiving attention with the cities reference group established in 2017 by the
Australian Government reviewing how to bring together data from both the public
and private sectors.
Finally, another issue when considering data is the potential for
confusion about the various types of datasets available. Mr Neil Plummer from
the Bureau of Meteorology commented that 'I think there is, at times,
uncertainty amongst planners and other agencies about just what datasets are
available and the best ones to use'. In particular, Mr Plummer noted that
there is a danger in solely relying on historical data given the current trends
in climate variables.
Disclosure and management of climate risk by corporate Australia
The committee received evidence discussing the importance of disclosure
by companies about their exposure to climate change to enable accurate pricing
of risk. In particular, the findings of the Taskforce on Climate‑related
Financial Disclosures established by the G20's Financial Stability Board and chaired
by Michael Bloomberg were noted.
The IGCC noted that it is increasingly recognised that Australian
businesses have 'an obligation to identify and manage material climate change
impacts for their operations and disclose material risks and impacts to the
The IGCC argued that investors are forcing change by reviewing their
investments and expecting that 'ASX300 companies which they invest in (or are
currently assessing with a view to potentially invest), to have developed
climate change adaptation strategies'.
In addition, the need for directors and boards to consider climate risks
carefully was noted. The legal opinion provided by Mr Noel Hutley SC and
Mr Sebastian Hartford-Davis in 2016 that climate change risks should be
considered by company directors and that these risks may be relevant to a
director's duty of care and diligence was referred to in several submissions.
The Senate Economics References Committee recently considered carbon
risk disclosure practices within corporate Australia. In its April 2017 report Carbon
risk: a burning issue, that committee concluded that 'carbon risk reporting
was not sufficiently prevalent amongst Australian firms, and that when
information was provided it was often of variable quality'. The committee recommended
that the Australian Government 'commit to implementing the recommendations of
the Financial Stability Board Task Force on Climate-related Financial
Disclosures where appropriate, and undertaking the necessary law reform to give
In its March 2018 response to the report, the Government welcomed the
release of the final report of the Financial Stability Board Task Force on
Climate‑related Financial Disclosures and encouraged stakeholders to
consider the recommendations. However, the Government argued that law reform is
not required because the Corporations Act 2001 is principles-based and
does not stop stakeholders from implementing the recommendations.
