Notes
  • An interesting set of alternatives, although I wish you had carried your carbon footprint analysis through to the evaluation of alternatives. As much as I love riding my bike, I very much doubt its impact on my carbon footprint is higher than virtualization or LED lighting. The proposed 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 are not on your stakeholder list).

    10. 10. Calculating activity data 0 CO2 emissions are calculated by multiplying activity data for each (sub) 0 0 0 0 0 category with the corresponding emission factor Emission factors – Measure of the average amount of a specific pollutant or material discharged into the atmosphere by a specific process, fuel, equipment, or source. It is expressed as number of kilograms or particulate per ton of the material. Example: Transport – CO2 from fuel use Electricity – CO2 from fuel combustion Water – Emission factor of supplying and treating the water in water companies Paper – emissions of producing and transporting the paper 10

    12. 12. Calculation assumptions: • Distance based on average distance of 35km travelled per student per day • 13 weeks per semester, 130 days per year • Paper usage of 3028 reams per school per year • Water usage of 4.58m3 per student per year Source: Singapore Environment Council – School Green Awards 12
    13. 13. Alternative environmental strategies 1. 2. 3. 4. 5. Transforming a significant proportion of our course delivery from classroom to an online format Buying an equivalent amount of carbon offset credits from CO2 Australia Energy Management Centre Data Centre Virtualization Bicycle Rental Services 13
    14. 14. Alternative 1: Transforming a significant proportion of our course delivery to an online format 0 A platform to deliver lessons to the student population through online methods, such as e-lecture, social media, etc. 0 Assuming that the school has in place a well-structured online lesson plan 14
    15. 15. Alternative 1: Transforming a significant proportion of our course delivery to an online format (Con’t) Benefits Disadvantages More flexible learning process, allow students to learn effectively at their own pace Lack of person-to-person interaction, discussion may not be well-facilitated online and queries may not be adequately answered Reduce carbon emission from Cause of procrastination, as learners students/employees commuting, paper with low motivation or bad study habits usage and the use of classroom might lag behind electricity Train one to be a more active learner and more independent at the same time In the event of emergency (for instance, SARS outbreak), student learning is not affected Slow and unreliable internet connection might cause one to be unable to learn effectively 15
    16. 16. Alternative 2: Buying an equivalent amount of Carbon Offset credits from CO2 Australia 0 A permit which allows a country or organization to produce a certain amount of carbon emissions and which can be traded if the full allowance is not used (Google Definition) 0 This form of credit allow a company to ensure that they keep within their target for carbon emission, at the same time, sell off any excess carbon credit to reward them. 0 This is in line with the Kyoto Protocol, which was adopted initially in 1997 by various countries 16
    17. 17. Alternative 2: Buying an equivalent amount of Carbon Offset credits from CO2 Australia (Con’t) Benefits Cons In cases where carbon emissions are inevitable, this carbon offset scheme provide a way to remediate the effects Does not solve the root problem; No incentive for companies to reduce emissions, merely offset Does not require any additional implementations for the organization purchasing the carbon credit Concentration of emissions in specific regions of the globe which can potentially be harmful for those regions Difficult to estimate amount of emission absorbed by trees Difficult to guarantee permanence of forests. Carbon trees are temporary and can “easily release carbon.... Through fires, disease, climatic changes, natural decay” 17
    18. 18. Alternative 3: Energy Management Centre 0 0 0 0 0 Automated sensor system implemented throughout NTU All electricity is switched off automatically when the venue is not in use Ability of Management Centre to remotely control all electricity usage Electricity resumes when user steps into the venue Saves about 75% (~ 123 Million kWh) of idle electricity Source: Princeton University; Low power Wake-on-LAN Challenges&Solutions 0 0 0 0 Replace all existing old fluorescent and incandescent bulbs with LED LED lighting lasts up to 10 times longer LED uses 67% lesser amount of electricity Ability to save up to 10.7Million kWh amount of electricity in NTU Source: EarthEasy; NTU 2013 ISCN-GULF Sustainable Campus Charter Report 18
    19. 19. Alternative 4: Data Centre Virtualization 0 Approximately, only ¼ of electricity is utilized for core functions of data centres 0 About 50% was wasted due to cooling purpose and other peripheral function 0 Web virtualization for data storage could reduce energy wastage by more than 50% 0 Ability to save up to 33% of electricity in NTU 0 Further extended through collaboration with Toshiba to implement Infocommunications Technology (ICT) Source: Host Europe: Advancing CSR and Sustainability In a Medium-Sized IT Company; Cool Idea-Potential One-Third Cut in Data Centre’s Bills 19
    20. 20. Alternative 5: Bicycle Rental Services 0 Provide bike rental services at nearby MRT Stations and within campus 0 Students can rent the bikes using their EZ-link cards 0 Reduces carbon emission from shuttle buses and provides an alternative means of transport for students 0 Also encourages a healthy lifestyle 20
    21. 21. Decision Criteria Affordability 0 Within financial capabilities of NTU 0 Initial cost < overall benefit Receptivity to change & ease of implementation 0 Drastic changes may result in backlash Impact on the environment 0 Extent of reduction of emissions 0 Effect on net environmental impact Availability of resources 0 Technical & monetary resources 21
    22. 22.

    23. 23. Recommendation 0 For a start, we will increase the number of online classes to replace existing seminars in a bid to reduce paper wastage and travelling needs. 0 At the same time, we will gradually implement the bicycle rental system at Boon Lay and Pioneer MRT Stations. 0 This will help us achieve our goal of reducing our carbon footprint. 23
    24. 24. Executive Summary 0 Carbon emissions have been increasing rapidly, leading to global warming. Each of us has a role to play in reducing these emissions. An organization like NTU will need to take up measures and various initiatives in order to reduce their carbon footprint, and play a part in corporate social responsibility to lead by example. 0 We have come up with several alternatives to achieve these objectives. Firstly, we aim to transform our normal seminar class into an online one, which enables us to reduce carbon emissions in many ways. Paper usage, the use of electricity classrooms, student commuting all cause substantial carbon emissions. Hence, online classes help to decrease our carbon footprint. 0 Another alternative would to be purchase carbon credits from companies like CO2 Australia. Purchasing such credits allows us to offset our carbon emissions and is hassle free. Other alternatives include using Energy Management Center , Data Center Virtualization and implementation of bicycle rental service. 0 When evaluating these alternatives, our decision criteria are based on ease of implementation, affordability, availability of resources and the impact on environment. 0 Taking up such measures bring in financial benefits, improves the reputation of the organization and most importantly, helps to alleviate the effects of our carbon footprint on the environment. 24
