Campus Carbon Calculator Overview Claire Roby Carbon Accounting Coordinator
Planning Challenges • What are our major emissions sources? • Where will our emissions be in 20 years – and where do we want them to be? • In what ways to does our current infrastructure present constraints, or opportunities? • What are the most cost effective measures to reduce our emissions? • How can we track our progress?
Why Complete a GHG Inventory? Management Tool Managing the energy costs along with the environmental impact Pedagogical Opportunity Incorporate the learning into a “living laboratory” Outreach Vehicle Strategically engage a community of individuals Civic Document Communicate your institutional commitment
Boundaries: What will we measure? • Temporal • Spatial • Scope • Scope 1: onsite and direct control • Scope 2: offsite and direct control • Scope 3: less control
Available to anyone for free download at www.cleanair-coolplanet.org • Inventory Module • Projection Module • Solutions Module
Data Input Scope 1 Scope 2 Purchased steam, electricity, or chilled water (kWh) Scope 3 Benchmarking BudgetsSquare footageStudent/Faculty/Staff FTE’s
Projection Module • Linear Projection • Normalized By Students/ Employees/Population 3. Normalized By Square Feet 4. Custom Trends
+ Cost ($) - Emissions Reduction (%) Solutions Module • Analyzes emissions reduction measures • Cost • Size of reduction • Prioritizes reduction measures • Ideal measure is low cost, large reduction
Steps in the Solutions Module • Come up with a series of projects • Enter a few pieces of data • Check the assumptions • The calculator will evaluate • Present this information
Outputs: The Big Three • 1-Internal Rate of Return (IRR) • 2-Net Present Value (NPV) • 3- Payback Time
