When estimating the CO2 emissions consequences of new electricity production facilities, the emissions of the marginal production technology, often coal power, are used as a reference. What fossil fuel production technology could be assumed when estimating CO2 emissions consequences of changing fuels?
Dear Hackl,
First of all, I believe using coal will remain for the coming years, since it is abundant and cheap. on other hand, using technology viz. Carbon Capturing and Storage (CCS) can mitigate CO2 and GHGs. Regards!

Hello Roman,
if you use coal power as reference you always have to argue why you chosed coal, and not gas or hydro power. In a first step the reference always should be the power mix. In further steps the dominating fossil power technology can be used. For example estimating a new power technology in Austria, it's obvious to look at hydro power as reference.
Regards!
Dear Roman Hackl
As concerned to fossil fuels utilization for power generation, Natural gas combined cycle has lower CO2 emissions without CCS, while Pulverized Coal fuel has highest CO2 emissions. similarly UCG-IGCC-CCS has the lowest emissions.
For your understanding I have attached a slide of Air emissions.
Regards.
Dear Roman,
For your information I send you a CO2 - comparison of different technologies for electricity production as well as of different countries, and a comparison of the influence of different propulsion technologies in cars.
Kind regards,
Mario
