Calvin College Carbon Neutrality Project Introduction Brian Medema
Class Mandate What would it take to make Calvin College Carbon Neutral? Calvin College Carbon Neutrality Project
Outline • What is Carbon Neutrality? • What is Calvin’s current footprint? • What can we do to achieve Carbon Neutrality? • Present our plan to be Carbon Neutral in 11 years. Calvin College Carbon Neutrality Project
What is Carbon Neutrality? • Carbon footprint is a net term. • Footprint = emissions – sequestration • Reduce emissions or increase sequestration • Carbon Neutrality is when emissions are equal to sequestration • When the footprint = 0 Calvin College Carbon Neutrality Project
Why Carbon? • Carbon Dioxide is the primary Green House Gas (GHG) emitted. • All other GHGs can be thought of as equivalent to Carbon Dioxide. • 1 ton CH4 has equivalent global warming potential to 23 tons CO2 Calvin College Carbon Neutrality Project
Climate Change http://www.physicalgeography.net/fundamentals/images/greenhouse.GIF Calvin College Carbon Neutrality Project
Why Carbon Neutrality? • Intergovernmental Panel on Climate Change • Fifth Report issued Nov 17th, 2007 • Climate change is unequivocal • Human activity has caused most of the warming in the last 50 years • From http://www.epa.gov/climatechange/ipcc2007.html#cite1 Calvin College Carbon Neutrality Project
Effects of an Overall Warmer Earth • Loss of sea ice. • Rising sea levels. • Shrinking Coastlines. • Shifting vegetation zones. • Effects Developed and Developing Nations differently. Calvin College Carbon Neutrality Project

American College and UniversityPresidents Climate Commitment • Signatories commit to: • Inventory their CO2 emissions • Set target date to become Carbon Neutral • Take immediate steps to reduce GHG emissions • Integrate sustainability into curriculum • Make action plan, inventory and progress reports publically available Calvin College Carbon Neutrality Project
American College and UniversityPresidents Climate Commitment • 448 college presidents have signed • At start of semester, less than 80 signatories http://www.presidentsclimatecommitment.org/ Calvin College Carbon Neutrality Project
Project Scope • Calvin College is responsible for: • All building operations (utilities) • Construction of new buildings • Food and Waste disposal • Daily commuter traffic • Service vehicle traffic • Calvin sponsored air travel • Not responsible for vacation travel Calvin College Carbon Neutrality Project

Carbon Reduction Options * Renewable Energy is not completely carbon free Calvin College Carbon Neutrality Project
Carbon Reduction Options • Green Energy Purchasing • Carbon Offset Purchasing • Conservation • Renewable Energy Production Calvin College Carbon Neutrality Project
Carbon Reduction Options • Green Energy Purchasing • Green energy has a 5¢/kW-hr surcharge. This is in addition to the 10¢/kW-hr fee. • To completely offset Calvin’s carbon footprint due to electricity usage would cost 1.1 million dollars. This is 1.2% of Calvin’s annual budget ($92 million). Calvin College Carbon Neutrality Project
Carbon Reduction Options • Carbon Offset Purchasing • EU is trading carbon offset credits at about 32.95 US$ per metric ton of CO2 • However, TerraPass.com sells carbon offsets for 11 US$ per metric ton of CO2 Calvin College Carbon Neutrality Project
Carbon Reduction Options • Conservation • Decreasing temperature in all buildings by 3 degrees Fahrenheit during the winter and 10 degrees during Christmas break would save about $172,000 and 3,555 MTCE (5.4% of total emissions) • Reduce electrical consumption • Turn off computers at night • Shut off lights when leaving a room Calvin College Carbon Neutrality Project
Carbon Reduction Options • Wind Turbine Installation • 800 kW of Power Capability • Estimated annual power production of 2053 MW-hr/yr • Unaided Payoff Period of 10.9 years • Net Present Value $820,000 Calvin College Carbon Neutrality Project
Neutrality Plan • Install 4 Wind Turbines • Offsets the emissions from energy purchasing and use. • Awareness • Implement options to minimize commuter traffic • Purchase Carbon Offset Credits to cover remaining emissions Calvin College Carbon Neutrality Project
Neutrality Plan 4 Wind Turbines This plan calls for a new wind turbine to be built every 5 years. The wind turbines will be paid off in 5 year periods using money saved from lower heating bills and a small amount of upfront capital. Calvin College Carbon Neutrality Project

Calvin College Carbon Neutrality Project Financing Joe Englin
Total Neutrality Costs • An upfront investment of $8,500,000 would be required to make Calvin College carbon neutral for 35 years. • This would be done primarily though the wind turbine project and carbon offset purchasing. Calvin College Carbon Neutrality Project
Implementation • Ideally, this plan would be implemented immediately, however $8,500,000 is a lot of money. • If we decide to implement the plan 10 years from now, we need to save $1,050,000 per year. • From that point on, we will have enough funding to stay carbon neutral for 35 years. Calvin College Carbon Neutrality Project
Community Values • We need to set an example for the community, even if it means spending more. • Examples of this would be dorm renovations and fully subsidizing the Rapid. • If we decided to push neutrality back one year, we could fund these projects.
Sources of Funding • Increased Parking Fees – This will help reduce carbon emissions and generate funding. • Raise Tuition – In addition to the increased parking fees, a 1.16% tuition increase would be required to fund this project. • Government Grants. • Donations. Calvin College Carbon Neutrality Project
46 Year Timeline Year 1: Increase tuition 1.16% Years 1-11: Save 82% of funds generated per year for carbon neutrality, spend 18% on green energy projects Year 11: Use the $8.5 million saved from years 1-11 to fund 35 years of carbon neutrality Years 11- 46: Deposit money saved into “Green Energy Account” and use it to fund other projects.
46 Years From Now • The wind turbine proposal will save Calvin a total of $15,800,000. • The money generated by the tuition increase could be saved and invested in new green energy technology Calvin College Carbon Neutrality Project
