Greenhouse Emissions
Our Approach
OneSteel is committed to pursuing
a high standard of environmental
management throughout its
operations, as outlined in our
Environmental Policy, available
online at www.onesteel.com. We
5
strive for continual improvement
of environmental performance, the
4
efficient use of resources, and the
minimisation or prevention of pollution.

OneSteel recognises that steelmaking
has inherent resources requirements
2
and emissions intensity. The following
section details our performance in
1
environmental areas as we seek to
use energy, fresh water and other
0
resources more efficiently where
5
economically viable.
We also seek to comply with applicable
4
environmental laws, regulations and
mandatory standards. Where these do
3
not exist, we apply appropriate internal
standards that reflect OneSteel’s
2
commitment to minimise adverse
environmental impacts resulting from
1
its operations, products and services.
Our Performance:
Greenhouse Gas Emissions
OneSteel’s energy and greenhouse
0
inventory is calculated for Australian
sites that fall under OneSteel’s
operational control. This captures
the vast majority of OneSteel’s
emissions with the non-Australian
operations likely to represent less
than one percent of OneSteel’s
greenhouse inventory.
OneSteel’s current energy and
greenhouse inventory aligns with
the accounting methodologies
of the Australian National
Greenhouse Emissions Reporting
Scheme (NGERS).
OneSteel’s greenhouse emissions for
the 2010 financial year are shown
to the right. Approximately 88% of
OneSteel’s greenhouse gas emissions
derive from the steelmaking and hot–
roll/forging operations at Whyalla in
South Australia, Sydney and Waratah
in New South Wales and Laverton
in Victoria.
OneSteel updates its historical
energy and greenhouse data in
line with changes to governmental
carbon accounting methodologies
and conversion factors so that a
common approach is presented in the
underlying data as far as practicable.

Greenhouse Gas FY06-FY10
Greenhouse Intensity of Steelmaking Sites FY06-FY10
1. Smorgon Steel data
obtained for FY06, FY07
prior to acquisition in
August 2007.
2. FY09 data shows the
effect of the Global
Financial Crisis on
production, and
therefore energy
use, emissions,
and intensities.
3. Historical data has
been adjusted where
possible against changes
in governmental
methodology and facility
boundaries in energy and
greenhouse accounting
against FY10 for a
comparable basis.
4. Steel Mill sites include all
on–site activities not just
crude steel production
(e.g. including rolling,
forging).
5. Whyalla Steelworks
intensity increased
in FY10 due to blast
furnace problems
and downtime.
