2010 GHG Inventory Update
• GHG Inventory
– Total Duke broken down into
• University = University/School of Med./School of
Nursing
• Health System contiguous to Durham campus
• CAP target – carbon neutral by 2024
– Only applies to University
– Did not include Health System in CAP target

2010 GHG Update - University
• Trends
– Campus electricity use going down
– Duke Energy emissions factors lower than
originally projected
– Reduction of coal in steam production
– People driving further for their commute but using
more alternatives

GHG/CAP Update Summary
• Emissions moving in the right direction
• Economic conditions have helped this trend
• 2010 data does not reflect full implementation of initial CAP
recommendations
•
•
•
•
East campus steam plant
LEED + policy
Energy conservation
Transportation demand management efforts
• Duke Energy is still large unknown
• Thinking about how to best revise CAP projections based on updated
information and still be able to measure progress
Facilities and Environment Committee
Next Steps
• Additional GHG Inventory analysis
– Review projected vs. actual financial impact
– Further detailed analysis of specific measures and
impact
– Develop schedule for reviewing/revising CAP projections
• Sustainability Strategic Plan
– Building on CAP - Food, recycling/waste, green
purchasing, water, land use
– CSC focus next year on developing targets
• Offsets
Facilities and Environment Committee
CARBON OFFSETS - First Offsets Project Operational May 2011: Duke
University-Duke Energy Swine Waste-to-Energy Partnership
Jet Aeration System for Nitrogen Treatment (April 13, 2011)
Digester prior to cover installation (April 13, 2011)
Facilities and Environment Committee
•Yadkin County system will capture methane and generate
electricity on the order of ~5,000 CO2e tons and ~500,000 kWh
(~500 MWh) of electricity annually; represents ~2.7% of
Duke’s annual offsets needs
•System meets stringent environmental performance standards
to substantially eliminate nutrients, ammonia, pathogens, odors
and metals and stop discharge of waste to surface and
groundwater
•Offsets Initiative seeing interest in replicating system; project
considered model pilot by federal and state leaders
