Trend in Total Greenhouse Gas Emissions 1990 – 2010

Upward trend…

2010

“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.

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

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.

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.

2013 Sustainability Survey2. I would be willing to pay a fee for covered parking at GCC if it was

offered as an option.

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 2025.

• 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.

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)


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)

Electricity Approach




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.



10% savings inAugust = $29,000

10% savings in February = $7,500


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

Electricity Approach




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.



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.
