Key performance indicators (PDF) - Xstrata

Environmental incidents
Xstrata’s operations record environmental
incidents according to severity, with
category 1 representing very minor
incidents with negligible impact and
category 4 or 5 representing major or
disastrous incidents with medium-to
longer-term impacts respectively. Category
3 incidents cause moderate, reversible
environmental impact and require
moderate remediation. Our target is to
achieve zero category 3, 4 or 5 incidents,
which was achieved for the first time
in 2010.

Greenhouse gases
(CO 2 equivalents (CO 2 -e) million tonnes)
Greenhouse gas (GHG) emissions are
measured as CO 2 equivalent tonnes (CO 2 -e).
Xstrata’s main sources of GHGs are from
electricity used, from methane released
during our coal mining in some regions and
from post mining fugitive methane
emissions from our closed coal operations.
We seek to reduce GHG emissions through
improved energy efficiency and by capturing
coal-seam methane to generate power
wherever possible.
In 2010, Xstrata’s direct (Scope 1) and
indirect (Scope 2) GHG emissions from
its operations rose by 7% and 20%
respectively, mainly as a result of increased

energy use due to higher production
volumes in response to an improved
demand for Xstrata’s commodities. Xstrata
Coal’s Australian operations continue to
invest in using methane from its operations
for energy generation where possible.
In 2010, generating capacity from our
methane-fired power stations was 31MW,
a similar level to that achieved in 2009.
The electricity generated is either used for
power by the mine or sold to the local grid.
