Notes
  • STRENGTHS: Strong beginning, with good stakeholder analysis, and professional effort to estimate carbon footprint AND report on current efforts to reduce it. The review of alternatives lacks depth, although the decision criteria are sound, and the comment on negative externalities is not linked to decision and action. Hoped to see the impact of each alternative on our carbon footprint.

  42. 42. Executive Summary Being a member of the International Sustainable Campus Network (ISCN), NTU is already mobilising the necessary resources to become one of the world’s leading universities in integrated sustainability education, research, energy efficient buildings and student involvement, reducing carbon footprints of the organisation to a minimum. However, more can be done to further improve the Brand of the school, and bring about benefits such as convenience towards its stakeholders. Being a School, the solution of educating students on reducing their individual carbon footprints has the most potential in changing the environmental scene on a macro scale. Taking a micro scale, our presentation explores the possibility of NTU further reducing its carbon footprints through E learning, buying of carbon offset credits and CNG vehicles to replace the shuttle buses. Carbon offset credits are not the way to go for NTU as it is a form of greenwashing. It will only give the perception that NTU is being environmentally friendly, when it is not reducing the amount of pollution it has. This will not bode well with the school’s values of being environmentally friendly. Also, the planting of trees does not have long term benefits as it only temporarily stores the carbon, and these trees will return the CO2 back to the environment when it is cut or burnt. E learning would not be a viable option as it will not be able to entirely replace physical classrooms and with notes still being printed during E learning, though it would be able to reduce a small portion of the carbon footprints by the NTU. The long term solution we propose would be to first continue with the current research in sustainable sources of energy by the full time staff. Next, NTU must continue striving in the education of the students on the importance of the planet component of the triple bottom line and its impact on businesses, as it is an intangible investment which would potentially affect their future employers and improve the carbon footprints of the world as a whole.
