1 Five Years of Green EffortsFive Years of Green Efforts “Commitment to Zero” Mary Harris, Physical Sciences Earth Day at GCC April 22, 2013

2 GCC 2010 Greenhouse Gas Emissions Snapshot Commuting & Purchased Electricity are the challenge.

3 Trend in Total Greenhouse Gas Emissions 1990 – 2010 Upward trend… 2010

4 “My action reflects a strong pledge by Maricopa employees to the goal and responsibilities of the Climate Commitment and sustainability.” Glasper On February 17, 2010 Chancellor Rufus Glasper signs the American College & University Presidents’ Climate Commitment. On September 20, 2011, President Kovala signs the American College & University Presidents’ Climate Commitment for GCC.

5 2013 Sustainability Survey 1.I support the efforts of GCC to reduce its carbon emissions. 6.8% (28) 2.0% (8) 11.5% (47) 35.9% (147) 43.9% (180) 1. Strongly disagree 2. Disagree3. Neither agree nor disagree 4. Agree5. Strongly agree

6 GCC 2013 – 2025 Climate Action Plan Project Timeline Insert graph here.

7 GHG Emissions Reduction Approach The main contributors to GCC’s greenhouse gas emissions are Commuting (51%) and Purchased Electricity (41%). –Commuting emissions must be counted because the emissions are due to the existence of GCC, and GCC’s ACUPCC commitment includes them. GCC will also: –Address lesser emission areas such as paper use –Incorporate more sustainability into the curriculum and college operations

8 Commuting Reduction Approach There is NO silver bullet; the recommendation is to use several approaches concurrently: –More car/van pooling, mass transit, low/zero emission vehicles, biking/running/walking –Shorter commutes, fewer commutes per week, reduced swirling –Everyone will be encouraged to use these via education and promotion. The recommendation is to use positive incentives such as covered parking and negative incentives such as parking fees as at state universities and many high schools.

9 Commuting Approach 10.5% (43) 13.4% (55) 22.5% (92) 33.7% (138) 19.8% (81) 1. Strongly disagree 2. Disagree3. Neither agree nor disagree 4. Agree5. Strongly agree 3.I am interested in exploring ways to reduce carbon emissions that result from my commute to GCC. These include car pooling, riding a bicycle, driving an all-electric or hybrid car or riding public transportation Sustainability Survey

10 Commuting Approach 33.7 (138) 1. Strongly disagree 2. Disagree3. Neither agree nor disagree 4. Agree5. Strongly agree 39.6% (162) 27.9% (114) 17.4% (71) 8.6% (35) 6.6% (27) 2013 Sustainability Survey 4.I would be willing to pay a parking fee to offset my personal commuting emissions.

11 Commuting Approach 1. Strongly disagree 2. Disagree3. Neither agree nor disagree 4. Agree5. Strongly agree 20.5% (84) 18.5% (76) 24.9% (102) 19.0% (78) 17.1% (70) 2013 Sustainability Survey 2.I would be willing to pay a fee for covered parking at GCC if it was offered as an option.

12 Commuting Reduction Approach If 30% more students carpool, ride the bus/train, walk or bike, there is a ~15% reduction in commuting GHG emissions by Offsets costing ~$120,000 - $370,000 per year will have to be purchased for the remaining 85%.This is ~$20 per student per year. The recommendation is to charge a parking fee, rather than raising tuition.

13 Electricity Reduction Approach Three main contributors: Building efficiency (25% reduction) GCC-generated solar energy (30% reduction) Buy renewable energy from SRP & APS, or buy offsets, dependent on market rates. (45% reduction)

14 Electricity Reduction Approach Building Efficiency (25%) 10% with fixed temperature set points 4% with smarter room scheduling 3% with early shut down 8% with efficiency projects (equipment & insulation)

15 Electricity Approach 1. Strongly disagree 2. Disagree3. Neither agree nor disagree 4. Agree5. Strongly agree 2.4% (10) 3.9% (16) 5.4% (22) 49.9% (205) 38.4% (158) 5.The indoor temperature of buildings on the GCC campuses should be kept at a constant level appropriate to the season and the activity in the building Sustainability Survey

16 Electricity Reduction Approach 10% savings in August = $29,000 10% savings in February = $7,500

17 Electricity Reduction Approach GCC-generated solar energy (30%) PV panels on parking shade structures, roofs, ground No energy after dark & storage expensive so must sell daytime surplus to utility and buy back at night. But, SRP only buys at 2.5 c/kWh

18 Electricity Approach 1. Strongly disagree 2. Disagree3. Neither agree nor disagree 4. Agree5. Strongly agree 5.1% (21) 2.5% (10) 10.3% (42) 30.4% (124) 51.7% (211) 7.GCC should install solar panels on rooftops and use the electricity generated to supplement campus energy needs Sustainability Survey

19 Electricity Reduction Approach Offsets (45%) Buy renewable energy from APS & SRP or buy good quality, validated offsets, choosing between them based on their market rates. The total cost of all forms of offsets would be ~$52,000 - $157,000 per year. This is ~$10 per student per year. The recommendation is to charge a parking fee, rather than raising tuition.

20 32.4% (133) 36.7% (151) 1.2% (5) 6.1% (25) 23.6% (97) Faculty (FT or PT) PSA MAT Student Other Breakdown of 2013 Sustainability Survey Respondents
