Notes
  • A rich set of alternatives, happy to see the impact of your proposed plan on our carbon footprint. The gradual shift from classroom to online learning may indeed be viable, but its risks demand careful thought and mitigation, such as potential impact on our international accreditation and on the market for our graduates (employers not on your stakeholder list). Current online education is often little more than a video of a lecture, accompanied by an assignment. If we envision a future in which teams collaborate across the Internet to solve complex problems, we must prepare students by building our learning environments to simulate this. Nice executive summary!

  26. 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.
