Recent EPA letter estimates annual emissions from development & use of Tar Sands crude at between 1.3 & 27.4 metric tons. Anybody know the annual world total? MMTC02e is precise unit shown in link.

According to the EIA, total world CO2 emissions were approximately 32.5 billion metric tons in 2013.

Those are millions of metric tons. Global annual emissions are about 40 billion tons, so this represents about 0.05%.

Correction: in your link, the EPA has estimated the emissions from tar sands at 1.3 - 27.4 million metric tons. In your abbreviation MMTCO2e, the first M is for million and the second for metric.

Global emissions are greater than 30,000 Tg CO2/year source: EPA. One Tg is one million metric tons.
