Duke University GHG Update/CAP Progress Report May 13, 2011 Facilities and Environment Committee Sustainability President’s Climate Commitment, Climate Action Plan and Greenhouse Gas Inventory Update Facilities and Environment Committee 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 Facilities and Environment Committee 2010 GHG Update 500,000 450,000 400,000 MTCO2e 350,000 300,000 250,000 200,000 150,000 100,000 50,000 0 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 Total Health System University 2007 levels = 445,561 Baseline 2009 levels = 419,706 ↓5.8% 2008 levels = 448,754 0.7% 2010 levels = 406,109 ↓8.9% Facilities and Environment Committee 2010 GHG Update - University 400,000 380,000 360,000 340,000 338,883 338,828 MTCO2e 322,355 320,000 308,310 300,000 280,000 260,000 240,000 220,000 200,000 2007 2007 Baseline 2008 2008 = 0% 2009 2009 = ↓5% 2010 2010 = ↓9% ~30,000 MTeCO2 reduced = 5240 cars removed from the road for year 3.75 more Duke Forests Facilities and Environment Committee 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 Facilities and Environment Committee Duke Energy Carbon Intensity 0.60 Oil & Gas 0.71% Hydro 1.40% Renewables 0.01% 0.50 Coal 46.68% Nuclear 51.20% 0.30 2010 Duke Energy Fuel Mix 0.20 Included in CAP Projections 2010 Revised Projections 0.10 Facilities and Environment Committee 2050 2048 2046 2044 2042 2040 2038 2036 2034 2032 2030 2028 2026 2024 2022 2020 2018 2016 2014 2012 2010 0.00 2008 Tons/MWH 0.40 Compared to CAP projections - University 390,000 2010 Actuals BAU CAP 370,000 MTCO2e 350,000 330,000 310,000 290,000 9% below 2007 baseline 12.5% below Business as Usual 270,000 250,000 2007 2008 2009 2010 •University emissions are going down since 2008 – 12% below BAU projections in 2010, Little higher than CAP target ~ 2% Facilities and Environment Committee Projections Compared to CAP - University 400,000 352,245 350,000 Linear Projection to 2024 308,310 300,000 MTCO2e 300,555 250,000 2010 Actuals BAU CAP 200,000 150,000 2007 2008 2009 2010 2011 Facilities and Environment Committee 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 2022 2023 2024 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 Facilities and Environment Committee
