Unaccounted gas amounts to nearly 2% of US greenhouse gas emissions

Putting together data from here and here.

These documents show:

-Over the last five years the US total annual unaccounted for gas averaged 247 billion cubic feet, which translates to 123 million metric tons of equivalent CO2 (according to my process for calculating shown here for Massachusetts).

-The total US GHG emissions were 6,633 Million Metric Tons.

123/6633 = 1.9%
