    1. Greenhouse Gas Emissions and Energy Efficiency Paula Hemmer Yin Pong Chang Division of Air Quality http://www.ncair.org June 15, 2012

    2. Purpose of Presentation • Greenhouse Gas Basics • Co-benefits of energy efficiency reducing GHGsaving money • Opportunity for low cost energy assessment • GHG Reporting

    3. What are Greenhouse Gases (GHGs)? Gas in the atmosphere that absorbs and emits radiation in the thermal infrared range Linked to: Greenhouse Effect Climate Change Source: US EPA

    4. “CO2 Equivalent” CO2e = ∑ emissionsi × GWPi

    5. Current concentration = 393 ppm (NOAA) • Vertical red bar at the end is the increase in atmospheric CO2 levels over the past two centuries • Shows CO2 levels have increased 100 ppm from pre-industrial levels • CO2 level of 450 ppm is targeted as the critical threshold beyond which catastrophic and irreversible change might occur. • Source US EPA

    6. Primary Source of GHG is the Burning of Fossil Fuels

    7. North Carolina GHG Emissions By Sector 3% of Total US Emissions Ranked 12th highest in US Gross Statewide Emissions Million Metric Tons CO2e Electricity Prod. Transport. Comm./Ind. Fuel Use Ind. Processes Agriculture Waste Mgm’t

    8. Energy Assessment Co-Benefits Save Money

    9. DAQ Grant for Energy Assessments • EPA/DAQ grant to provide cost-free or reduced-cost assessments • Goal is to educate facilities on interdependency between • energy consumption • greenhouse gas emissions • energy costs • Program is open to industrial, commercial and institutional facilities • Applications need to be submitted by July 2013 • More information and application: • http://www.ncair.org/monitor/eminv/gcc/ghg_grant.shtml mechanical and aerospace ENGINEERING

    10. Who is Getting the Energy Assessments? • No. of applications = 35 • No. of assessments completed = 19 • No. of assessments “in the works” = 16 • No. Available = Approximately 60 • Types of facilities: Furniture Electronics Lumber Tobacco Chemical Hospital Food Paper Textiles Plastic Foam/Pipe

    11. Potential Reductions Identified through Grant * The payback time for implementation of each energy conservation measures varies from 2 to 62 months, with an average time of 22 months. Some measures have immediate payback.

    12. GHG Reporting Programs • EPA Mandatory Reporting of Greenhouse Gas Rule (MRR) Facility with ≥ 25,000 metric tons CO2e must report Electronic Greenhouse Gas Reporting Tool (e-GGRT) http://www.epa.gov/climatechange/emissions/ghgrulemaking.html • NC DAQ Voluntary Reporting Program Any permitted facility can submit emissions DAQ can provide technical assistance, spreadsheets Air Emissions Reporting On-line System (AERO) http://daq.state.nc.us/monitor/eminv/forms/GHG_Emission_Inventory_Instructions_Nov2009_Voluntary.pdf

    13. EPA GHG MRR Data http://ghgdata.epa.gov/ghgp/main.do
