Introduction In 2007 CSCC s President signed the American College and University Presidents Climate Commitment (ACUPCC), a voluntary agreement for higher education institutions to reduce impacts of climate change and work towards climate neutrality. Climate neutrality is the balancing of carbon emissions and sequestration. CSCC will work toward this challenge through cost efficient emissions reductions to minimize its impact from campus operations. Emissions will be offset through forest sequestration and investing in local climate reduction projects. CSCC s emissions inventory has shown opportunities for direct and indirect emissions reductions. Direct emissions will be reduced through sustainable building management, while indirect emissions can primarily be reduced through student and employee commute solutions including promotion of alternative and public transportation. Climate change has been called the greatest challenge for humanity. Efforts to reduce human impact on climate change have been driven at a variety of levels from grassroots campaigns, personal efforts as well as government and educational institutions. CSCC is a strong leader in providing affordable education as well as demonstrating its environmental values through progressive policies and efficient campus operations management. Carbon emission reductions will be driven by CSCC s Energy Efficiency Plan as well as its Sustainability Policy. Commitment As a citizen of a complex ecological system, Columbus State Community College is committed to doing its part to sustain the environment for future generations. The college shall engage in financially-sound academic and operational activities that will result in the reduction of solid waste, pollution, and energy consumption - CSCC Sustainability Policy As an early signatory to the ACUPCC and a leader in energy efficiency planning, Columbus State Community College (CSCC) has led educational institutions in the pursuit of sustainability. CSCC is focusing on high impact, financially efficient reductions in emissions to achieve its goals and targets. Building energy consumption is the primary driver of Scope 1 & 2 emissions, thus reductions will come from lighting retrofits, campus HVAC system upgrades, computer system energy consumption optimization, and vending machine controls. CSCC will continue to develop its long-term climate strategy through future building efficiency initiatives, student/employee incentive programs to reduce Scope 3 transportation emissions as well as investment in local renewable energy and forestry initiatives to ultimately achieve climate neutrality. CSCC has set short and long-term emissions reduction targets. CSCC aims to reduce emissions 20% of baseline fiscal year 2004 by 2014 and 80% of baseline emissions by 2050. In order to ensure these targets are met and emissions projects are successfully implemented, several initiatives have been developed to promote CSCC s institutional commitment to sustainability and emissions reductions. The Sustainability Committee was created to advance CSCC s sustainability programs on an ongoing basis. The Committee includes students, staff, faculty and administrators representing a broad cross section of disciplines. The Board of Trustees and the President authorized a Sustainability Policy to declare CSCC s commitment and dedication to the principles of sustainability. In new construction, CSCC has committed to striving to build to U.S. Green Building Council s Leadership in Energy and Environmental Design s Columbus State Community College Climate Action Plan 3
(LEED) silver standard. CSCC also works with the Association for the Advancement of Sustainability in Higher Education (AASHE) as well as the Energy Star program to reduce its environmental impact. Community Education In 2008, CSCC was one of only 65 schools in the United States recognized by the National Wildlife Federation as an Exemplary School for Having Recruiting Programs and Offering Interdisciplinary Degrees in Environmental or Sustainability Studies. CSCC offers an Associate of Applied Science degree in Environmental Science/Safety and Health and a Certificate in Sustainable Building. Construction, environmental design, and applied science are integrated into these programs. The certification includes course work in the environment, architectural and LEED design, and construction management. The use of energy modeling simulation packages are introduced in the program, allowing students to compare multiple design schemes to determine which designs optimize climate and site conditions. Arts and Sciences faculty integrate sustainability into courses that include geology, geography, biology/environmental science, and chemistry. Faculty have engaged in discussions about broadening the curriculum, and two faculty members on CSCC s Sustainability Committee are actively engaging faculty in discussions on and activities related to sustainability. A major component of CSCC s long-term climate reductions will involve the participation of the CSCC and greater Columbus community. The primary source of CSCC emissions is indirect emissions from employee and student commuting, thus meaningful reductions will require promotion of alternative modes of transportation, behavioral changes and community education. In addition to program marketing and incentives to promote car sharing/car pooling, CSCC will work with the Central Ohio Transit Authority (COTA) to make public transportation available to core living areas for students and employees that are currently not well served. Carbon Footprint It is estimated that CSCC operations emitted 62,462 MT eco 2 from July 1, 2006 through June 30, 2007. This is a decrease of 4.9% over emissions from 2006. The primary drivers of emissions decreases are waste sent to the landfill (20.2% decrease), electricity usage (9.8% decrease) and commuting miles (3.3% decrease) which comprise 0.9%, 36.1%, and 55.4% of total emissions respectively. A summary of FY 2007 emissions by category and WBCSD/WRI (2004) scope are presented in the table below. Results for FY 2004 through FY 2006 can be found in the Historical Emissions Inventory Results section below. Columbus State Community College Climate Action Plan 4

Mitigation Strategies CSCC s carbon emissions mitigation strategy is a 40 year plan to efficiently work toward climate neutrality. A flexible and sustainable approach will allow for steady emissions reductions over the life of the plan. This approach will also enable iterative planning updates to account for changes in technology, economy, campus community behaviors, and regulations. A summary of the plan will be promoted throughout the campus with guidelines for behavioral changes to empower individuals and the community to make a difference. This plan will be revisited every five years over the lifetime of the plan to track progress and ensure its success. Below is an outline of the emissions reductions projects for CSCC that focus on building systems. Buildings comprise over 99% of Scope 1 & 2 emissions while also accounting for 44% of total emissions.

The cost efficiency of the project portfolio is outlined in Figure 9. The MT eco2 per payback year shows both the high impact reductions of emissions for projects with large savings for the capital invested. Figure 10 shows the impact of the projects listed above on emissions trajectory. With both the projects outlined above and the proposed long-term reduction projects, CSCC is on track to achieve its emission reduction goals. The proposed long-term reductions of scope 1 and 2 emissions focus on energy efficiency of buildings and sourcing renewable energy. By providing and promoting alternative and public transportation as well as reducing single occupancy vehicle travel, CSCC will reduce Scope 3 emissions from student and employee commuting. CSCC will also invest in local urban forestry property to offset remaining emissions. In addition to reducing carbon emissions, the polyculture forest will serve as an educational laboratory for students to learn about the complex benefits of forest ecology, carbon sequestration, water cycling and the resulting impacts on urban ecology. CSCC s mitigation plan represents a broad, diverse and efficient approach to carbon emissions reduction. Enacting this plan will provide a model for the Columbus community to emulate and will also engage the CSCC community to not reduce its negative impact, but increase its positive impact. By implementing local forestry projects, CSCC is not only acting as a responsible steward of its urban environment, it is leaving a legacy of proactive response to our greatest challenge.
