Raleigh's Sustainability Goals and Emerging Technologies in Wastewater

1. Megan Anderson, Sustainability Manager TJ Lynch, Public Utilities Assistant Director What is the City of Raleigh doing to meet its Sustainability Goals? Emerging Technologies in Wastewater August 21st, 2019

2. What is Raleigh’s Office of Sustainability • Mission of the Office • Work collaboratively to prioritize economic, social, and environmental efforts at an individual, organizational, and community-wide level. • Test new technologies and encourage new ways of thinking to positively impact the environment, our local economy, and all who live, work, and play in Raleigh. • Current Projects Examples • Climate Energy Action Plan Community Climate Action • Resilience & Equity • Innovation & Smart Cities, Electric Vehicles • Environmental Stewardship, Food Insecurity

3. Sustainability Tracking & Rating (STAR) Metrics

4. Climate Action Background 2007: • Raleigh City Council endorsed the U.S. Conference of Mayors’Climate ProtectionAgreement 2010: • Office of Sustainability initiated Raleigh’s first GHG emissions inventory (municipal operationsonly)  2010: • Climate Energy Action Plan for Raleigh’s municipaloperations • Community-wide GHG emissionsinventory 2016: • Updated municipal and community-wide GHG emissionsinventories • Renewable Energy Overview with the North Carolina Sustainable Energy Association 2018: • CCAP- focus on community-wide GHG drivers and strategies • Intent to inform GHG reduction and renewable goals

5. CEAP Top 34Strategies Evaluation Criteria Financially Responsible Operational Impacts Realistic /Implementable Coordinates with Other Projects Carbon ReductionPotential 5

6. GHG Evaluation: Footprint • Units: lb. CO2e / Functional Unit Editable Excel Workbook Option for default and/or user defined values for inventory items and GHG equivalents References / explanations for default values Dynamic figures Total GHG comparison across alternatives GHG hotspot analysis within alternatives

7. GHG Footprint 0.06 -0.55

8. Current vs. Bioenergy GHG Production Bioenergy is able to convert digester gas to RNG which allows for GHG Footprint to decrease with increasing flow to Neuse River RRF Typical Passenger Car is estimated to emit 5.5 tons CO2e per year

9. Our Current PerformanceMunicipal GHG emissions There was a 19% decrease in GHG Emissions from the 2007 baseline to 2014. A large decrease was seen in methane emissions at the closed Wilder’s Grove Landfill and some energy efficiency.

10. Community-wide Greenhouse Gas Emissions There was a 2% increase in GHG Emissions from the 2007 baseline to 2014 despite an approximate 16% increase in population

11. Community-wide Climate Action Plan GOAL: 80% Reduction in GHG emissions by 2050 TOTALS: Buildings: 55% Transportation: 41% Waste: 1%

12. Community-wide Climate Action Plan Objectives Evaluate setting goals- climate/GHG emissions and renewable energy Community Education and Outreach Define Raleigh's climate challenges and opportunities Forecast future GHG emissions and set goals for reductions Apply national best practices in climate action planning Engage scientific, business and grassroots community leaders to develop strategies Analyze the needs and potential impacts of climate change to vulnerable communities using an Equity Framework Educate, Engage and Empower residents, businesses and institutions to implement positive actions to reduce emissions

13. CCAP Forecasting and GoalsBusiness as Usual (BAU) • BAU 68% ↑ • (9.4 million MTCO2e) • Buildings & Energy (5.2 million) • Transportation (3.9 million) • Waste (125,870) • 80% GHG reduction by 2050 (1.8Million MTCO2e)

14. CCAP Forecasting andGoalsAggressive Forecast

15. CCAP Teams at work understanding strategies and goals

16. Other Climate Initiatives Urban Sustainability Directors Network • High Impact Practices study NC Cities Initiative • Governments/stakeholders working on climate across NC Executive Order 80- State of North Carolina • Governor Cooper’s - Executive Order 80 • 40% reduction in GHG emissions by 2025 • 80,000 new EV’s on the road by 2025 Triangle Regional Resilience Assessment • Climate and non-climate impacts

17. Electrification of Transportation Study By 2040, Over 50% of All New Cars Could Be Electric Electrification of light-duty motor pool Publicly accessible charging infrastructure Public charging needs and demand assessment IT infrastructure and data-driven decision making Aligning transportation electrification with existing City plans and budgets Equitable economic development and public engagement Equity and access City roles and responsibilities Identify current and future opportunities in Raleigh

18. Public Charging Infrastructure What is the City’s role? What is the demand? How can it complement other projects?

19. Municipal Fleet Electrification How to integrate into replacement cycles? How to use current funding mechanisms? How are we tracking data? How do we expand infrastructure?

20. Equality vs. Equity

21. Energy Burden in Wake County = State Average More than 288,000 households in North Carolina live at 50 percent of the poverty line, and spend 35% or more of their income on energy.

22. Triangle Regional Resiliency Assessment

23. 48 days above 92 degrees- record in 2010 • Social Vulnerability Index: • Families below poverty line • HH with disabilities • 65 and older • Limited English… Resiliency: Extreme Heat

24. Resiliency: Properties & Flooding • Future: • more frequent and intense precipitation • Continued population growth and urbanization • Increased localized flooding • Higher risk to residential, commercial, industrial property

25. Resiliency: Road Access & Flooding • Roads: • Provide day to day transportation needs • Vitally important for safety and emergency services • Higher risk for properties with a single access point
