The sum of such efforts allowed us to save approximately KRW 2.4
billion per year and reduce GHG emissions by 10,458 tCO2-eq.
Improving our operational methods
Our energy saving approach is multi-pronged: not only do we
improve the efficiency of our conventional operational methods
in the tire manufacturing and energy use process, but also we
work to widen the awareness of our entire team concerning
such issues. Implementing the power demand management
system, reducing the use of unnecessary equipment, and
adopting staggered production all aided in the reduction of the
unnecessary consumption of power and thermal energy. We also
managed our workspaces with reasonable temperatures and
smart lighting to conserve energy. Eventually, these activities
enabled us to reduce nearly KRW 2.4 billion in expenses per
annum and mitigate GHG emissions by 12,986 tCO2-eq.
exemplary innovation is our Technodome which saves us nearly

the curing press, and the improvement of heat exchangers.
