DIRECT EMISSIONS (SCOPE 1)
3% OF TOTAL 2017 EMISSIONS
Direct Emissions relate to activities
that directly generate greenhouse
gases, such as the combustion
of natural gas, transport and
nontransport fuels, as well as
through the use of synthetic
gases in air conditioning. Our
Direct Emissions increased by
approximately 9% in 2017.
The primary reason for the increase
in Scope 1 emissions are synthetic
gases used for the US centres.
These emission sources occur
on non-regular schedules due to
maintenance, leaks, or upgrades
to refrigerant systems. In addition,
natural gas consumption at UK
centres increased in 2017.

INDIRECT EMISSIONS (SCOPE 2)
36% OF TOTAL 2017 EMISSIONS
Indirect Emissions are the second
largest component of our Total
Emissions. These emissions
arise when the suppliers of
electricity, heating, steam and
cooling to Westfield Corporation,
combust fossil fuels to generate
energy sources. Our Total
Indirect Emissions decreased
by 8% in 2017. This decrease
was due to our ongoing effort to
reduce GHG emissions through
emission reduction initiatives,
such as upgraded LED lighting
several centres (see US LED
program), improved heating and
ventilation efficiency, and reduced
lighting loads.
