26. Executive Summary
Seminar 3, Group 5
Tan Chee Yang, Cai Wenjie, Foo Cheng Wen, Leonard Tan, Wong Xin Yi, John
NTU has a strong focus on Sustainability and has become a member of the International
Sustainable Campus Network (ISCN) in 2012. Our sustainability efforts include an integrated
sustainability education, research, energy efficient buildings. However, we are only at the beginning
of our long term goal of becoming a carbon neutral campus. While we strive to be carbon neutral,
NTU also has to protect the interest of our stakeholders, such as our students, government and NTU
officials.
Despite our sustainability efforts, NTU currently emits 99,013,736kg of carbon dioxide
annually. Our group has come up with a 3-prong strategy for NTU to become carbon neutral in
future.
Our recommendation for you to achieve this goal consist of 3 steps. First, to minimise
energy usage in the school by having more e-learning weeks in a semester and implementing a
bicycle-hire service within the campus. This will reduce NTU’s carbon footprint as less commuting is
required. Next, we will maximise the energy efficiency of the NTU campus. Tapping on the strength
of NTU’s researchers, innovation in research and development will lead to technology advancement
which allows us to use energy more efficiently and thus reduce our carbon emission. The final step is
to purchase carbon credits to offset the remaining of NTU’s carbon emissions.
With our strategy, NTU will remain as an Asian and global leader in sustainability research
and translational applications on campus.
