00;00;04;08 - 00;00;05;27

Where ideas connect.

00;00;08;17 - 00;00;10;11

Michael, great to have you with us today.

00;00;10;11 - 00;00;14;14

Can you talk us through a little bit

about why not understanding

00;00;14;17 - 00;00;17;29

emission

baselines can lead to poor decisions?

00;00;18;17 - 00;00;20;22

Yeah, I think that the answer to

that is twofold.

00;00;20;25 - 00;00;25;07

There's obviously aspects of voluntary

and mandatory reporting that companies

00;00;25;17 - 00;00;30;06

need to ascribe to annually,

and a bad decision would be

00;00;30;08 - 00;00;34;04

to erroneously report to the regulators

or to your stakeholder group.

00;00;34;19 - 00;00;37;24

And so having a good understanding

of your baseline in that respect is,

00;00;37;27 - 00;00;39;10

is quite important.

00;00;39;13 - 00;00;43;11

But then we think of the functional

aspects of decarbonization is

00;00;43;14 - 00;00;47;29

you really want to understand your problem

space better or as well as you can,

00;00;48;02 - 00;00;52;05

so that you can implement solutions

to be able to decarbonize.

00;00;52;17 - 00;00;56;25

One aspect of that

that we see is with respect to scope three

00;00;57;05 - 00;01;02;01

currently organizations

and typically are using spend

00;01;02;04 - 00;01;07;13

based analysis for scope three emissions

based learning, which from an industry

00;01;07;16 - 00;01;11;04

perspective is perfectly acceptable

and largely applied.

00;01;11;07 - 00;01;14;21

But where the difficulty is, is,

is that they're unable to effect change

00;01;14;24 - 00;01;17;24

in their organization

based on that methodology.

00;01;18;01 - 00;01;21;26

And so really running to ground

material emissions

00;01;21;29 - 00;01;26;03

within scope three and elsewhere,

with appropriate methodologies for,

00;01;26;06 - 00;01;30;14

for doing Baselining is very,

very important to both decarbonization

00;01;30;25 - 00;01;33;14

and your subsequent reporting.

00;01;33;17 - 00;01;37;20

And how can spending more time

on this help businesses?

00;01;37;23 - 00;01;41;20

Michael, if you can go into a little bit

more detail and can you talk us through

00;01;41;24 - 00;01;45;09

scope three briefly

before diving into that question?

00;01;46;11 - 00;01;49;25

So businesses with scope three

emissions exposure are those

00;01;49;28 - 00;01;53;20

that typically have upstream

and downstream supply chains.

00;01;54;00 - 00;01;56;16

And if we think about it,

many businesses do.

00;01;56;19 - 00;01;59;19

And where they want to be understanding

00;01;59;24 - 00;02;02;23

emissions is in material

aspects of upstream.

00;02;02;26 - 00;02;07;19

So this could be, precursor materials

for their products or feedstocks,

00;02;08;02 - 00;02;09;08

but also downstream.

00;02;09;08 - 00;02;10;18

Where is the product used?

00;02;10;21 - 00;02;14;26

How is it transported,

how is it warehoused, etc., etc..

00;02;15;08 - 00;02;19;09

And that is different for different

products, different businesses

00;02;19;12 - 00;02;22;08

and different services

that the industry might be offering.

00;02;22;11 - 00;02;26;22

So it is really imperative for businesses

to properly understand

00;02;26;25 - 00;02;29;25

their supply chains

both upstream and downstream.

00;02;30;10 - 00;02;32;26

And then to, spend a bit of time

00;02;32;29 - 00;02;35;29

understanding the boundary

of where they want to analyze

00;02;36;07 - 00;02;39;22

and to properly understand

the materiality of those emissions.

00;02;40;02 - 00;02;44;04

For example, you might be a manufacturer

of a small product,

00;02;44;09 - 00;02;48;25

but you have a large, logistics supply

chain that sits behind the distribution

00;02;48;28 - 00;02;53;05

of that, to your client base

and really running to ground the emissions

00;02;53;08 - 00;02;57;25

for your logistics, can be quite helpful

in you being able to firstly understand

00;02;58;00 - 00;03;01;02

your business as usual emissions

for scope three and logistics,

00;03;01;10 - 00;03;04;10

but also then working

with your logistics partners

00;03;04;13 - 00;03;08;04

or if they are owned within the business,

with your fleet management

00;03;08;07 - 00;03;12;08

teams, to be able to understand how

you can solve, your emissions problems.

00;03;12;11 - 00;03;14;10

For those scope three elements.

00;03;14;13 - 00;03;17;27

And at times there can be uncertainty

00;03;18;00 - 00;03;21;09

and investment risks

associated with decarbonization.

00;03;21;22 - 00;03;26;24

Can you talk us through how we could

potentially reduce that associated costs

00;03;27;00 - 00;03;31;23

and uncertainty, as well as potentially

de-risk decarbonization?

00;03;32;10 - 00;03;35;22

If we go back to the traditional business

model, have how the industry interacts

00;03;35;25 - 00;03;39;26

with the supply chain, it's often

very transactional, and that results in

00;03;40;04 - 00;03;43;04

you asking of end of what something costs

and really not

00;03;43;07 - 00;03;46;06

having any say in the development of that

or the optimization of that.

00;03;46;09 - 00;03;48;04

And you accept the market price.

00;03;48;07 - 00;03;52;25

I think with decarbonization,

what it enables or requires of industry

00;03;52;28 - 00;03;55;25

is to be more involved

with your supply chains

00;03;55;28 - 00;04;00;04

in both understanding how they're going

about their business from an emissions

00;04;00;07 - 00;04;03;06

perspective and potentially energy

efficiency perspective.

00;04;03;17 - 00;04;08;10

But also to understand where the costs are

within that part of the business,

00;04;08;19 - 00;04;12;28

because your vendors or your suppliers,

downstream or upstream,

00;04;13;09 - 00;04;16;05

will be themselves

potentially implementing,

00;04;16;08 - 00;04;18;17

decarbonization solutions,

00;04;18;20 - 00;04;21;28

within their business,

which could have a cost impact on you

00;04;22;08 - 00;04;26;06

and understanding where those costs

are ascribed in their value chain,

00;04;26;23 - 00;04;30;07

and in their business is very important

to understanding

00;04;30;16 - 00;04;34;21

and reducing the uncertainty

of your own decarbonization efforts.

00;04;35;05 - 00;04;39;10

And I think more broadly,

what decarbonization also promotes within

00;04;39;13 - 00;04;42;27

industry is quite an amount

of diversification from coal business.

00;04;43;09 - 00;04;46;09

So we see a lot of manufacturers

that might typically work

00;04;46;15 - 00;04;50;15

in the development or production

of components, or they might be OEMs.

00;04;51;01 - 00;04;52;18

And now they're having to think about

00;04;52;21 - 00;04;55;20

energy storage, or they're having to think

about rooftop solar.

00;04;55;23 - 00;04;59;12

So they're getting into the power business

in some respects,

00;04;59;15 - 00;05;03;11

which is not where they skillset,

not where they keep efficiencies.

00;05;03;14 - 00;05;07;17

So being able to properly understand

cost in those aspects

00;05;07;28 - 00;05;12;02

and maybe who's the most appropriate

organization to be,

00;05;12;08 - 00;05;14;08

conducting those activities

within your business,

00;05;14;08 - 00;05;18;22

you may choose to outsource to a vendor

that has a better cost appreciation.

00;05;19;04 - 00;05;20;14

In that respect.

00;05;20;17 - 00;05;24;20

Now, we've spoken

about industry roles of organizations.

00;05;25;03 - 00;05;27;27

Do you think that there is a role

for government to support,

00;05;27;27 - 00;05;32;29

or even something like blended

finance models in this space?

00;05;33;13 - 00;05;34;13

Yeah, completely.

00;05;34;14 - 00;05;36;11

And I think the the role for government

00;05;36;14 - 00;05;40;09

and also potentially industry

lobby groups, are several fold.

00;05;40;17 - 00;05;44;13

You have the very literal contributions

that government need to make,

00;05;44;24 - 00;05;48;19

to support and de-risk, project

financing, through grants,

00;05;49;01 - 00;05;53;04

potentially through assistance

in blended finance, where the government

00;05;53;07 - 00;05;57;02

will will take on some of the financial

risk of some of these, projects,

00;05;57;08 - 00;05;58;22

to get them over the line.

00;05;58;25 - 00;06;02;08

But there are other things that government

can do, to support industry,

00;06;02;11 - 00;06;06;11

because if we think of decarbonization

along the engineering development

00;06;06;14 - 00;06;09;26

chain, there's all sorts of interventions

that government can do to assist

00;06;09;29 - 00;06;14;16

the industry, whether that be assistance

with concept and feasibility studies,

00;06;15;02 - 00;06;18;21

whether that is, providing support

and assistance in front end

00;06;18;24 - 00;06;20;15

engineering and design.

00;06;20;18 - 00;06;24;10

But it could also be in the implementation

construction phases

00;06;24;13 - 00;06;29;12

where the government can either provide

capital or expertise, where organizations,

00;06;29;19 - 00;06;34;04

can't necessarily source

that value within their organization.

00;06;34;17 - 00;06;37;18

So there's a whole heap

of supporting mechanisms that government

00;06;37;21 - 00;06;43;20

can and should consider in terms of skills

within a particular organization.

00;06;44;03 - 00;06;48;17

How can organizations

across the different regions

00;06;48;20 - 00;06;53;24

sport gaps in their skills for better

planning in the decarbonization space?

00;06;54;07 - 00;06;57;05

And the second part to

this question is how important

00;06;57;05 - 00;07;00;22

is it to retain workers from sectors

like coal

00;07;01;03 - 00;07;05;19

and transitioned them into new roles

as we move through decarbonization?

00;07;06;11 - 00;07;08;02

Yeah, I think that's a very good question.

00;07;08;02 - 00;07;10;07

And, there is no silver bullet to this.

00;07;10;07 - 00;07;14;05

And I think the industry is,

having a degree of,

00;07;14;11 - 00;07;17;08

introspection as to how to appropriately,

00;07;17;11 - 00;07;20;20

position themselves

to increase skills and capability.

00;07;21;03 - 00;07;24;23

I think the first thing

is to properly understand business needs.

00;07;25;02 - 00;07;29;08

When a business considers technology

and engineering that consider their needs,

00;07;29;24 - 00;07;33;05

from a skill set perspective, they need

to be thinking along the same lines.

00;07;33;08 - 00;07;38;16

And we see companies that have long term

strategies to get into different, biofuel

00;07;38;19 - 00;07;42;10

plays, different future fuels industries

where they don't have

00;07;42;21 - 00;07;45;21

a domestic capability

within their organization.

00;07;45;26 - 00;07;48;08

And being able to pivot a workforce.

00;07;48;08 - 00;07;50;25

And you mentioned coal

as an example of that.

00;07;50;28 - 00;07;54;13

We see a lot of concern within the coal

sector of how those communities

00;07;54;16 - 00;07;57;17

and how those workforces,

will be repositioned

00;07;57;20 - 00;08;00;27

within this, this new economy,

this decarbonized economy.

00;08;01;06 - 00;08;04;21

So being able to understand

your needs is very, very important.

00;08;04;29 - 00;08;09;01

And I would say those needs sit right

across the vertical within the business

00;08;09;04 - 00;08;12;01

when we're considering

both technical needs.

00;08;12;04 - 00;08;16;05

So the needs to be able to design,

to operate, to maintain

00;08;16;13 - 00;08;21;03

these new technologies also within boards

and senior management

00;08;21;06 - 00;08;22;15

positions, is making sure

00;08;22;15 - 00;08;26;11

that we have the appropriate roles

and responsibilities within organization

00;08;26;14 - 00;08;30;16

to be able to orchestrate,

some of these decarbonization efforts.

00;08;30;19 - 00;08;34;18

One example is, sectors like wind,

00;08;34;21 - 00;08;38;27

completely designed differently

than, say, the oil and gas industry.

00;08;39;17 - 00;08;40;11

Thank you Michael.

00;08;40;11 - 00;08;43;16

And that leads me

to my final question for you.

00;08;44;04 - 00;08;46;29

You've given us

some really good scenarios, examples

00;08;46;29 - 00;08;50;04

and if you had $10 billion today,

00;08;50;21 - 00;08;54;03

how would you tackle the issues

we've just discussed?

00;08;55;01 - 00;08;57;25

I'd start that saying

10 billion isn't quite enough.

00;08;57;27 - 00;08;59;00

It's all I've got.

00;08;59;00 - 00;09;02;10

Unfortunately,

my joke answer is to reinvest

00;09;02;13 - 00;09;05;13

it and, get a little bit more money to

to play with.

00;09;05;16 - 00;09;07;12

But if I was really to sit back in

00;09;07;12 - 00;09;10;20

my chair and see where that 10 billion

could be more effectively

00;09;11;07 - 00;09;16;12

used, I would say I'd be putting

that towards skills building in areas

00;09;16;15 - 00;09;21;25

where your country, your organization, is

seeking to really develop its, expertise.

00;09;22;07 - 00;09;25;24

When we talk about Australia,

there's a lot of, conversations

00;09;25;27 - 00;09;30;17

around the hydrogen economy and some of

the biofuels and future fuel space.

00;09;30;20 - 00;09;35;08

I think really, tooling up the workforce

and making sure that's adequate staffing

00;09;35;11 - 00;09;39;06

capabilities, technical expertise,

and to a degree, sovereign capacity

00;09;39;14 - 00;09;44;20

to be able to build, to innovate, within

these areas would be money well spent.

00;09;44;29 - 00;09;48;29

The governments are very, very skilled

at setting up innovation hubs.

00;09;49;02 - 00;09;53;21

And, and really coalescing universities

around skills building.

00;09;53;24 - 00;09;57;09

So I think the government would be

best placed to spend that 10 billion.

Where ideas connect

The Australian Government has earmarked AUD 10 billion in lifetime investment commitments to help the country hit net-zero emissions by 2050. But is this enough? In this podcast episode, we touch on the challenges faced by the decarbonisation industry and what we can do to stay on course and avoid stagnation.

Catch up on:

  • Why the decarbonisation industry has hit a wall
  • What new technical skills are required to fast-track decarbonisation
  • The need for clear emission baselines and precise carbon footprint calculations
  • How much investment is needed to decarbonise Australia

This conversation covers the critical need for clear emissions baselines, the challenges of Scope 3 emissions, the importance of precise carbon footprint calculations and how government can assist the industry.
