long-term impacts of emissions<br />
reduction efforts<br />
In 1990 our clinker factor stood at 84 percent and no alternative<br />
fuels were used in our production processes. Since then,<br />
we have taken significant steps to reduce our CO2 emissions<br />
and overall environmental footprint. Clinker reduction and<br />
alternative fuel substitution have greatly reduced the direct<br />
emissions from our manufacturing processes, while projects<br />
such as our EURUS wind farm help to curb the indirect CO2 impacts<br />
associated with our power needs. Together, these efforts<br />
represent more than 7.5 million tons of avoided CO2 emissions<br />
compared with our 1990 baseline. That’s equal to offsetting<br />
the annual emissions of 1.3 million passenger vehicles, or saving<br />
nearly 16 million barrels of oil from being consumed.<br />

developing alternative energy sources<br />
Our EURUS wind farm in Oaxaca, Mexico, has the capacity to<br />
provide 25 percent of the energy needed to run our Mexican<br />
operations, and in 2011, allowed us to avoid 489,169 tons of<br />
CO2 emissions.<br />
We are exploring ways to further reduce our carbon footprint<br />
by using efficient process technologies and changing the way<br />
we source electricity. In 2011, for example, CEMEX Philippines<br />
launched a collaborative project with Sinoma Energy<br />
Conservation Ltd to devise a system for capturing waste heat<br />
from our kilns to produce clean, alternative electricity. At our<br />
Solid Cement plant in the island of Luzon, this technology is<br />
expected to yield 6 MW of onsite energy production each year,<br />
representing 27 percent of energy needs at the Solid plant and<br />
producing an annual cost savings of approximately 35 percent<br />
from grid rates.<br />

Through these and other projects, CEMEX will continue to<br />
evaluate the feasibility of low-carbon and renewable energy<br />
solutions, including the possibility of wind and solar energy<br />
generation at many of our operations.<br />
