Q615. For a 2011 report with the "Liquefied Natural Gas Storage" option selected, how does the "calculation utility" excel spreadsheet account for "Population Count and Emission Factors" when providing the user with a final CO2e number?

A615. For the “Liquefied Natural Gas Storage” calculation utility, the spreadsheet multiplies Population Counts, Emission Factors, and conversion factors to output methane emissions in tonnes CO2e for each source.
Final CO2e emissions = (Population Count) x (Emission Factors) x (Volume conversion)
