I agree that this organization pushing the data makes it suspect, in the sense that given finite time resource I'd probably not bother to review this study for methodological consistencies and instead wait on confirmation or refutation from secondary sources.
It appears that they are just parroting back data from BP [1], which unfortunately just passes the buck to another organization with suspect motivations. Their methodology refers to the IPCC recommendations, so if followed should at least be consistent with other attempts to measure CO2 output, but without more detail of the inputs to the model it's difficult to be sure.
