Notes
  • Very thorough research, well-structured presentation, interesting but rather complex proposals. Not clear 'what I should do when I leave the room,' an important take-home for change agents. If we envision a future in which teams collaborate to solve complex problems, we’ll have to prepare our students in learning environments that simulate this, either in the real world or across the Internet.

  30. 30. Executive Summary       Singapore topped the list of carbon emitters per capita in Asia-Pacific region in 2010, reported by WWF. The Singapore NEA responded that the country is greatly dependent on fossil fuels as its small size limits the switch to alternative sources of energy. NTU being a leading institute for education and research thus has to stay ahead and to reduce its contribution to the amount of carbon emitted. The university does have measures in place to reduce the energy consumption and to CO2 emission. This presentation identified 10 alternatives and evaluated them based on Cost, Ease of Implementation, Impact on Environment and receptivity. Hence we present our C2SR strategy to assist NTU in reduction of GHG and energy consumption. The water reduction and waste minimization aims to reduce indirect GHG emission and by utilizing Gamification, we encourage students and staff to save and take ownership of energy usage. In addition, due to limited sheer size of Singapore, we recommend the use of Vertical Farming and grow crops on barren walls along the campus. This cools down the building’s internal temperature, improves energy efficiency, and creates a greener campus. Also, we plan to raise awareness by having “sustainability ambassadors” to implement CO2 reduction project and to spread the message of our cause. Situation Analysis Alternatives Recommendations Risk & Mitigation Conclusion 30
  31. 31. Calculation of Scope 1: Direct GHG emissions Scope 1 Carbon footprint = 123,061 tons/year Direct GHG emissions   Direct transportation sources Purchased electricity Based on ISCN-GULF report, NTU utilizes 164 million kwh in 2012. We take this to be purchased electricity. To calculate direct GHG from direct transportation sources, we used a guesstimate 1. NTU’s main transport comes from public buses, shuttle buses and cars 2. For buses, assume that every hour there are 16 public and shuttle buses roaming NTU, covering a distance (to-and-fro) of 20km/day. In a day, there are 18 operating hours. Therefore, total distance = 16 x 20 x 18 = 5760km/day. 3. For cars, there are 53 carparks in NTU, with each carpark, on average, having 40 carpark lots. Assume total number of expected cars in NTU correlates with the quantity of carpark lots that was planned by NTU, this implies that total number of expected cars = 53 x 40 = 2120 cars. With 50% utilization (since carparks are not always occupied, especially during the term breaks), and each car covering a distance of 10km/day, implying a total distance of 0.5 x 2120 x 10 = 10,600km/day Based on carbon calculator, NTU produces 123,000 tons/year of carbon dioxide 4. Carbon footprint, using a carbon calculator online, is 43 tons/year for cars and 18 tons/year for buses. Total carbon footprint = 61 tons/year Source: Steven Sprangers, http://www.carbonify.com/carbon-calculator.htm , http://www.carbonindependent.org/sources_bus.htm , NTU data Situation Analysis Alternatives Recommendations Risk & Mitigation Conclusion 31
  32. 32. Calculation of Scope 2: Electricity Indirect GHG emissions Scope 2 Carbon footprint = 3,409 tons/year Electricity indirect GHG emissions    Employee commuting Student commuting Water Usage Based on ISCN-GULF report, NTU utilizes 814,000 cubic metres of water in 2012. We take this to be water usage. Based on carbon calculator, the carbon footprint is 708 tons/year To calculate indirect GHG from employee commuting, we used a guesstimate 1. In 2012, total expenditure on manpower is $644,603,000. Assume that, on balance, the average pay for each staff (high pay for professors is balanced out by the comparatively lower admin staff etc.) is $80,000. This implies that estimated number of employees is 8000. 2. Average distance per staff (to and fro) = 50km 3. Total distance travelled per day = 8000 x 50 = 400,000 km.day 4. Carbon footprint = 671 tons/year To calculate indirect GHG from student commuting, we used a guesstimate 1. 2. 3. 4. 5. 6. Total number of students = 33,000 Total number of students that stay in hall = 16 halls x 550 = 8,800 Total number of students who don’t stay in hall, implying they have to travel = 33,000 – 8,800 = 24,200 Average distance per student (to and fro) = 50km Total distance travelled per day = 1,210,000 km/day Carbon footprint = 2,030 tons/year Source: Steven Sprangers, http://www.carbonify.com/carbon-calculator.htm , http://www.carbonindependent.org/sources_bus.htm , NTU data Situation Analysis Alternatives Recommendations Risk & Mitigation Conclusion 32
  33. 33. Calculation of Scope 3: Other Indirect GHG emissions Scope 3 Carbon footprint = 2,500 tons/year Other indirect GHG emissions To calculate indirect GHG from paper consumption, we used a guesstimate  1. 2. 3. Paper consumption Total number of students = 33,000 Each student uses 26kg (2 boxes of A4 paper) per year = 858,000kg Based on campus carbon footprint calculator, carbon footprint = 2500 tons/year Source: Steven Sprangers, campus carbon footprint calculator, NTU data Situation Analysis Alternatives Recommendations Risk & Mitigation Conclusion 33
  34. 34. Calculation of carbon emissions reduced as a result of converting course content to online learning 1 Reduce paper consumption Estimated to reduce carbon emissions by 1000 tons 2 1. 2. Paper consumption in NTU is producing 2500 tons/year. The best estimate for carbon emission is 1000 tons under Fermi’s law. Using guesstimate, Reduce carbon footprint as a result of student commuting Estimated to reduce carbon emissions by 1015 tons 3 Using Fermi’s law, Reduce electricity consumption that arises from classroom usage Estimated to reduce carbon emissions by 1230 tons 1. 2. Total carbon footprint from students who commute is 2030 tons/year If most of the content is converted to online learning, there is a lesser need for students to travel to school. Since a significant content is online, a reasonable estimate of reduction is 50%. Using guesstimate, Total purchased electricity’s carbon footprint is 123,000 tons/year 2. Since NTU’s bulk of activities come from teaching, the impact of the online learning is high, and we estimate a 0.01% reduction in electricity consumed Note: Fermi’s law indicates that the overestimates and underestimates will balance out, and the error is usually within one order of magnitude.
