How much CO2 does normal diesel produce?

The UK government on Page 130 here says diesel has an emissions factor of 0.086 kgCO2e/MJ fuel.

Carbon and Sustainability Reporting Within the Renewable Transport Fuel Obligation

The US government says on page 19(or 45 according to acrobat reader) that normal diesel produces 633.28 g CO2/bhp-h

Life Cycle Inventory of Biodiesel and Petroleum Diesel for Use in an Urban Bus

Now my unit converter [1] says there are 2.68452 MJ in a horsepower hour.

so the UK government says 0.086*1000*2.68452 = 230 g Co2/bhp-h and the US says 633

So the US and the UK don't agree on the NORMAL diesel Co2 footprint, yet alone the biodiesel.

Help!!! Which of these is right?

This is the reason the UK thinks that Biodiesels have about 70% the footprint of normal diesel and the US thinks it's 17%. They disagree on the footprint of normal diesel !!

Answers on my user page please!
