GDP is one of the vulnerable elements in a climate change emission scenario study. I need to be sure which type of GDP is meant to be reported and the importance of the the two calibrations. GDPppp vs GDPmer. Many thanks.
In general it all depends on the methods used in the study. If you have a comparative analysis that includes several countries better use PPP. Otherwise, MER will be more appropriate.
Is there any Reliable statistics about gdp meR? What anchor you would like to use? Us $? Sounds a bit impossible to me advice keep to gdp ppp
The IMF provides a simple explanation of PPP and MER. Please find it through the following link:

Jan Jansen , Nikolay Peykov and Yudhi Dharma Nauly thank you for contributing to this discussion. I tried reading up some articles and it is obvious that GDP ppp provides more realistic picture of differences in human economic welfare and it is also more useful in a comparative assessment for different nations. However, the GDP mer has also been very useful especially in deriving dynamic spatially scenarios which has not been done with the GDP ppp. Indeed, the Intergovernmental Panel on Climate Change (IPCC) has made use of the GDP mer in the SRES for projecting GDP. The reasons are: first, historical output data at MER are more readily available than at PPP exchange rates; second, in the context of optimizing regional consumption paths, internal prices are used rather than the world average price level; and third, international trade in energy and possibly carbon (in the future) take place at GDP mer.
