1. City of Boulder Operations Sustainability Management Planning Alison Schwabe, Sustainability Program Manager, McKinstry Joe Castro, Facilities & Fleet Manager, City of Boulder Colorado Climate Network Workshop, 30 April 2013

2. Inventory Process Step 1 – Make Inventory Decisions Step 2 - Gather Data for Base Year  Use master data workbook (ICLEI)  Keep detailed notes and sources! Step 3 - Calculate Emissions  CACP software (ICLEI)  Consumption x GHG emissions factor x GWP = GHG emissions Step 4 – Forecast and Report Emissions (optional)  Forecast to target year  Report by scopes to avoid double counting

3. COB Inventory Decisions Made [Reference Document: Local Government Operations Protocol v 1.1, May 2010] http://www.theclimateregistry.org/downloads/2010/05/2010-05-06-LGO-1.1.pdf Base year: 2008 Boundary: Operational control (owns and operates-measure what you manage) Electricity emissions factor: eGRID 1.2% increase from 2005-2007 1,883 lbs CO 2 /MWh to 1,906 lbs CO 2 /MWh Scope 3: employee commute, business travel, wells-to-pump, materials, solid waste

4. Electricity Emissions Factor  Local (Xcel)  2007: 0.75 kg-CO 2 /kWh  Regional (eGRID)  2007: 0.86 kg-CO 2 /kWh  State average

5. Stationary Sources Buildings and Facilities Public Lighting-streetlights, traffic signals Water Treatment & Transport- pumps, irrigation Refrigerants Solid Waste from Government Operations Wastewater Treatment Facility COB Sources of Emissions Mobile Emissions Vehicle Fleet Mobile Equipment Refrigerants Wells-to-Pump (Scope 3) Employee Commute Business Travel Materials Production Asphalt & Cement Copy Paper Computers & Hardware Fertilizer Food Inventory Boundary: All facilities, vehicles, etc. operated Not including facilities leased to others Not including jointly owned facilities not operated

6. COB 2008 Baseline Inventoried Emissions by Sector

7. COB Inventoried Emissions by Sector 30.4 mt-CO 2 e/employee, 0.64 mt-CO 2 e/capita Commerce City=38 (2008) and Westminster=25 (2006)

8. COB 2008 Baseline Inventoried Emissions by Source

9. 2008 & 2011 GHG Emissions by Sector Reductions Buildings – 20% Materials – 62% Wastewater – 19% Water – 32% Public Lights – 6% Fleet – 5% Overall: 26% decrease from 2008 to 2011

10. Data Collection Challenges  Overall Guidance – collect the least amount of information that will be used  Questions about why the City needs the data  Methodology – what data to collect?  Baseline data harder to collect – older  Accuracy – are the data good?  Timeliness – staff are busy  Keeping data organized (very important!)
