P 2 Intern Working Group EPA’s Pollution Prevention GHG Calculator David A. Carter Kansas State University Pollution Prevention Institute July 6, 2010

``I think you should be more explicit here in step two. . . ''

Useful Conversion Factors 1 • • • 1 CCF = 100 CUBIC FEET 1 MCF = 1, 000 CUBIC FEET = 1 MMBTU 1 MBTU = 1, 000 BTU 1 MMBTU = 1, 000 (106) BTU 1 THERM = 100, 000 (105) BTU = APPROX. 100 CUBIC FEET OF NATURAL GAS = 29. 3 k. Wh • 1 k. Wh = 3412 BTU • 1 SCF = 1, 000 BTU* *P 2 Program GHG calculator uses 1, 027 BTU • 1 metric ton (tonne) = 1. 1 short ton 1 Association of Energy Engineers Certified Energy Manager Manual

EPA’s Pollution Prevention GHG Calculator • Quantifies reductions based on conversion factors – Electricity conservation – Green energy sources – Fuel use and substitution of greener fuels – Greening chemistry (reduced emission of GHG directly – Materials management (TBD) – Water conservation

EPA Pollution Prevention Program’s GHG Calculator (cont) • Converts standard metrics into metric tons of carbon dioxide equivalent (MTCO 2 e) using standard national conversion factors • Aggregates by category and by total project (does not carry project titles forward) • National conversion factor 7. 21 x 10 -4 MTCO 2 e/k. Wh; can also use state-specific emission factors – – Iowa: MRO, 9. 54 x 10 -4 MTCO 2 e/k. Wh Kansas: SPP, 7. 1 x 10 -4 MTCO 2 e/k. Wh Missouri: RFC, 8. 58 x 10 -4 MTCO 2 e/k. Wh (Why? Should be SPP/SERC) Nebraska: MRO, 9. 54 x 10 -4 MTCO 2 e/k. Wh (also has WECC) • GHG Conversion Tool_April 7 2010. xls
