that all-natural gas stocks are combusted. BLM Colorado is assuming 100 percent combustion of coal as
well, as we are unaware of any other non-combustion uses for coal stocks at non-trivial scales.
Table 2.2-19 provides BLM's estimate of each fuel's GHG contribution and the percent of the carbon
budget increment the fuel's COz emissions would represent on an annualized basis.

Emissions units are Million Metric Tons, Estimates are based on EPA missions facto , *Data assumes 50 percent
federal DRMS production for Federal mines with no ONRR documentation, percent Carbon Budget(CB)calculated
for mean face value(500Gt)
The snapshot data above shows that consuming all of the Federal energy produced in the U.S. in 2017
(onshore & offshore) would be equivalent to 0.26 percent of the remaining carbon budget, while the
Colorado component of the Federal mineral estate is approximately 0.01 percent of the carbon budget
and just 1.14 percent of total U.S. fossil fuel energy emissions (COze) on an annual basis. At the current
production rates shown, total Federal mineral combustion would exhaust the carbon budget in
approximately 377 years, while Federal minerals in Colorado would do the same in about 8,794 years.
These timelines show a stark contrast relative to the current global scope emissions track. The data also
provides a nice illustration of why coupled carbon is an appropriate metric for establishing a target-based
emissions budget, in that relative to the COze estimates, COz emissions from fossil fuel combustion clearly
