Summary: Telstra has shown the possibility for its business to deliver emissions reductions
across the economy. We are now using our own products and services to help our customers
reduce their own emissions. And we are using these solutions ourselves and quantifying the
environmental benefits.
Background
Telstra’s original energy efficiency programs began in the 1970’s with early research into
renewable energy technologies, leading to Telstra being one of the largest solar energy
generator in Australia with over 10,000 solar powered sites. Over the past 10 years, Telstra
started reporting externally its environmental performance. In 2007, Telstra cast a vision for
how we could help reduce greenhouse gas emissions across the economy1 through the
“Towards a High Bandwidth Low Carbon Future” report. Improvements in how Telstra
approached environmental and sustainability reporting, along with continually introducing
environmental initiatives, has led to a 10 percentage point increase in 2009 on the Dow Jones
Sustainability Index (DJSI) and maintained Telstra’s Climate Leader status on their Australia/
New Zealand Climate Leaders Index by the Carbon Disclosure Project2 for the past 3 years.
In late 2009, Telstra announced a carbon reduction target. Since that time and up to the current
time in 2010, Telstra has undertaken the development of a whole-of-company energy
allocation model3 to assist us achieve this target. With a strong commitment to reducing our
carbon footprint, Telstra is now well positioned to enable its customers to reduce their own.
Purpose
The challenge for Telstra is to minimise energy consumption and Telstra’s exposure to rising
electricity prices, while delivering the vital services our customers need. In short, we need to
reduce our environmental footprint while growing our business.
In this presentation, I will share with you what we have done to deliver on this vision to enable
our customers to reduce their greenhouse gas emissions. There are three areas where Telstra is
improving the management of its energy use and at the same time minimising the
environmental impacts on our customers.

We are doing this by:
• Enabling our customers to reduce their greenhouse gas emissions;
• Measuring our own carbon footprint onto our largest customers; and
• Quantifying the time, cost and carbon savings from product/solution deployment.
Enabling our customers to reduce their greenhouse gas emissions
Firstly, we are working with customers to reduce their greenhouse gas emissions. We know
that high speed broadband will enable the deployment of low carbon solutions across the
economy such as video conferencing, remote working, and applications of these innovations
through industry verticals such as e-Health, e-Education4 and growth in sales of these solutions
is increasing. For example, for every tonne of greenhouse gas the telco and ICT sector
generate, our industry sector is enabling the wider economy to reduce its greenhouse gas
emissions by a factor of five or more.
The industry, and Telstra, has made a commitment that we can deliver these benefits, and there
is an expectation that we will deliver on this promise. Well, I can proudly say that in Telstra,
we are delivering. The example I’ll share is in reducing transport emissions. Much of
transport’s emissions come from vehicle fleets. Within Telstra, we are enabling the efficient
deployment of field work forces using Trimble Geo Manager, a solution we offer our
enterprise customers5, particularly those in the transport sector with large fleets and field
service staff6. Let me explain. In Telstra, we have a total vehicle fleet of 14,000 and a field
workforce of about 6,000. These are the staff that connect your landline or conduct repairs
when there has been an outage. Trimble GeoManager relies on field staff being connected via
wireless broadband. It finds the shortest distance between field jobs so work can be scheduled
in the most time-effective and fuel-efficient way. It uses GPS and GIS technology with the
additional feature that it sends a regular positioning signal to a satellite. It allows work
schedulers to match the closest field staff, that have the needed skills, to the next nearest job.
In Telstra, Trimble GeoManager, has reduced travel kilometres between field jobs, by 6.5
percent year on year since 2006/077.
When running a large field work force and vehicle fleet like ours, this equates to millions of
litres of fuel saved each year. That’s a significant positive impact on green house gas emissions
reduction. But the greatest business value in implementing Trimble has been the recovery of
lost time from the field workforce. Telstra has seen an increase of more than 10 percent
productivity in our own field work force since installing Trimble.
This is transformational change: Increased productivity and reduced carbon footprint. Imagine
that impact multiplied across a national broadband network.

This is based on the 26% reduction of km/task that our national Regional Service Delivery vehicles has reported
during the period financial year 2005/6 (44.5) to 2008/9 (37.4).

Measuring our own carbon footprint onto our largest customers
Secondly, we are measuring our own carbon footprint onto some of our largest customers. For
those of you who may be wondering if the current uncertainty about carbon regulation is a
reason to put your supply chain impacts of your products and services to the side, let me share
with you the actions taken by one of our largest customers, which shows just how seriously
some customers are concerned about costs of carbon in their business.
In 2008, Telstra was approached by an enterprise customer asking us to measure our carbon
footprint onto their operations8. Telstra undertook a life cycle assessment (LCA) for this
customer to measure the environmental footprint of provision of our products and services into
their operations9. Telstra calculated the energy use and greenhouse gas (carbon) emissions
resulting from provision of its products and services to that customer. The study determined the
impact for both Telstra and the customer, allowing both organisations to better understand and
manage the energy and emissions impacts of the telecommunications products and services
provided to the customer10.
Here are the results: 20 percent of the energy and greenhouse gas emissions impact was
attributable to Telstra and 80 percent attributable to the customer11. The impact of the
customer-premises equipment (CPE), which was predominantly routers, was significant and
higher compared with all other impacts from our footprint such as fixed line and mobile calls.
In fact, the emissions from the CPE represented eight percent of the customer’s total carbon
footprint.
This collaboration between Telstra and a major customer has provided a focus for both
organisations to reduce the carbon emissions impact from equipment needed to be deployed by
our customers to use Telstra’s services. This has included seeking alternative solutions to
replace or upgrade legacy routers to models and configurations that are more energy efficient.
It has enabled both Telstra and the customer to look at energy use and greenhouse gas
emissions management in a new light. For Telstra, we have a better understanding of the
contributions of our individual products and services to our own greenhouse gas emissions
footprint. For the customer, they can see how telecommunications solutions directly impact
their power consumption. Undertaking a carbon footprint onto our customers is also consistent
with our philosophy of working transparently with our stakeholders and disclosing our
environmental liabilities12.

This request became a catalyst for Telstra to better understand the carbon impact of its products and services,
building on the company-level carbon footprint (from emissions sources eg electricity, fuel & waste to landfill)
and business unit level carbon footprint already conducted.

Life Cycle Assessment (LCA) methodology was used in the study and it was limited to operational energy
consumption due to the complexity of products and services used by the customer. Embodied energy or other
material environmental impacts were not considered. Allocation rules were developed to apportion Telstra’s
network energy use to specific Telstra products and services. Although a partial LCA was completed, ISO
Guidelines were used as guidance for this study (AS/NZS ISO 14040:2006(E), AS/NZS ISO 14044:2006).
11
The total carbon emissions impact for both Telstra and the customer was 22,237 tonnes CO2e or the equivalent
to the greenhouse gas emissions from approximately 1,600 average Australian households
(http://www.environment.gov.au/settlements/gwci).

Refer to Telstra’s submission to the Carbon Disclosure Project (CDP) at www.cdproject.net. Telstra has
participated in this initiative since its inception in 2003 and for the past 4 years we have been represented on the
Climate Leaders Index demonstrating our commitment to reducing our greenhouse gas emissions and resilience to
impacts of extreme weather events.

Quantifying the time, cost and carbon savings from product/solution deployment
Finally, ICT products, such as video conferencing and remote working, provide additional
value to their functional and technical capabilities through reduced impact on the environment.
Realising this value for the customer, through the development of products and services, is
both a challenge and opportunity facing the ICT sector. Telstra has embraced this challenge
and opportunity by measuring the environmental impacts and benefits of selected products and
services, and underpinning these efforts by continuing to improve commitment to its own
environmental performance.
In April 2009, Telstra and WWF jointly launched a whitepaper on ‘Using ICT to drive your
Sustainability Strategy’13 that incorporated sophisticated Return on Investment (ROI) tools.
The four calculators enabled customers to understand the potential cost, productivity and
emissions savings from individual product use. Although only an estimation, the transparency
and breakdown of the components presented a credible tool that is valued by customers and
further tools are under development.
Follow up to this work has been in calculating the carbon emissions, productivity and cost
savings achieved, from our products and solutions, doing this in real-time, realising enhanced
value for the customer. This approach was piloted internally at Telstra in 2009 by measuring
the travel savings from video conferencing deployment including avoided carbon emissions.
At the beginning of each video conference, a software tool captured the number of attendees
substituting physical travel. The tool then used their geographic locations, the latest emissions
conversion factors, and real time data for flight and vehicle costs, to accurately measure the
travel savings14. This example demonstrates not just the direct environmental benefits of the
product, but also the link to measurable cost savings and productivity benefits. Quantification
of environmental benefits across selected business offerings, such as remote working, online
billing, and video conferencing, integrates with productivity and costs savings. And this
results in additional business value.
Conclusion
In closing, good environmental management is important for our business but it goes beyond
us - it is also important for our customer’s business. Telstra must meet its customer’s needs for
coverage, speed, bandwidth, and service, but customers are also a priority in our approach to
managing the environment: we are enabling customers to achieve their own carbon reduction
commitments.
