17 sustainable development goals (SDGs) to continue advancing our wafer
processing solutions to play a critical role in enhancing today’s
digital world. With the help of all UMC employees, we successfully
reached our ‘Green 2020’ goal for energy saving, water and waste
reduction within the first year of setting the target. In addition, UMC
created the industry’s first ‘Green Award’ to bring together outstanding
programs and ideas through the selection of eco-conservation proposals
for award consideration. This award facilitates society’s involvement in
contributing positive ideas to help better the environment. We have also
set up an ‘energy saving volunteer team’ to provide energy-saving and
carbon reduction services for the underprivileged and maximize
enterprise resource productivity in order to actively address the
problem of global warming. In the future, we hope partner with all
stakeholders to work together for a sustainable future.”
