2015 Greenhouse Gas Emissions Inventory Report A Summary Presentation prepared for September 2016

2015 Goal: 15% Reduction • 2008: Phoenix City Council adopted a mandate to reduce greenhouse gas (GHG) emissions to 5% below the 2005 levels by 2015. • 2009: 2005 GHG Inventory for city operations completed – GHG emissions projected to rise 14% if the city did not take appropriate action • 2012: Inventory update found that Phoenix already surpassed the 5% reduction goal – Phoenix City Council adopted a new goal to reduce GHG emissions to 15% below 2005 levels by 2015 sustainabilitysolutions.asu.edu

2015 Reporting Scopes Total GHG emissions related to city of Phoenix operations in 2015 was 588,153 MT CO 2 e emissions. sustainabilitysolutions.asu.edu

Most Impactful Changes 1. Reduction of fugitive and process emissions (-48,367 MT CO 2 e) 2. Renewable energy generation • 4.3% of energy used in 2015 • 12,550 MT CO 2 e emissions avoided • Reduction of building electricity emissions and water services emissions 3. Switch in the fuel profile (-12,855 MT CO 2 e) 4. LED traffic signal retrofits (-2,488 MT CO 2 e) sustainabilitysolutions.asu.edu

Changes in Data • Updated Global Warming Potentials (GWPs) Greenhouse IPCC AR2 IPCC AR4 Gas GWP GWP CO 2 1 1 CH 4 21 25 N 2 O 310 298 • Updated Emissions Factors for GHG Inventories from EPA – Including eGRID emission rates • The 2012 inventory reported 678,150 total MT CO 2 e (2005) • The 2015 inventory now reports 696,709 total MT CO 2 e (2005) sustainabilitysolutions.asu.edu

Employee Commuting Emissions • Employee commuting emissions are dominated by gasoline in both 2005 and 2015. • 2015 accounted for bus and light rail which was not reported in originally 2005. However, bus commuting miles have been backcasted for 2005. 2005 2015 Fuel Type Commuting Commuting MT CO 2 e MT CO 2 e Miles Miles Gasoline 80,555,678 30,153 83,504,307 31,091 Electric 36,477 10 52,927 14 CNG 277,905 80 264,775 45 LPG 284,192 88 311,161 58 E85 12,609 2 460,061 80 Hydrogen -- -- 1,790 0 Bus * 3,158,885 338 3,158,239 184 Light Rail ‡ -- -- 289,157 38 Total 84,325,745 30,672 92,659,836 31,829 *Commuting miles for 2005 were backcast from 2015 levels using employment data. ‡ The Valley Metro Light Rail did not exist in 2005.

2015 Greenhouse Gas Emissions Reduction Report Thank you to city of Phoenix employees, residents and business owners, who are on the ground supporting the city’s efforts and who are working toward reducing their own greenhouse gas emissions. It may seem like we have a long way to go, but as this report proves, we can make a difference. sustainabilitysolutions.asu.edu
