CO2 Emissions in South Korea, 1945-2012

So the following table and figure are comparing different estimates of South Korea's CO₂ emissions from 1945-2012.
I want to know why BP's estimates for recent years are much larger than those of other institutions.

Note: Original carbon contents of CO₂ emissions in the GCP estimates were multiplied by a conversion factor (= 44.0095/12.0107) to make CO₂-equivalent numbers.
