Carbon dioxide emissions from petrochemical production are a key
category in the Russian national greenhouse gas inventory. Up to 95% of CO2
emissions in this category come from the production of ethylene, methanol,
and carbon black. Refining emissions estimates for petrochemical production is
necessary to reduce uncertainty in CO2 emissions estimates. This paper presents
the results of developing a national CO2 emission factor for carbon black
production based on data from manufacturing enterprises. The national emission
factor was developed using the IPCC Tier 2 methodology, which relies on a
carbon mass balance approach across the production cycle. The factor was
developed using data from six major carbon black enterprises by determining
individual emission factors for specific production facilities and then computing a
production-weighted average. Emission factors are highly dependent on the
feedstock structure. The use of gaseous feedstock significantly reduces target
product yield and increases СO2 generation to 12 or more tons of CO2 per ton of
carbon black. In contrast, the utilization of liquid and solid feedstock
substantially reduces CO2 emissions, with specific CO2 emissions reaching up to
2.07 tons of CO2 per ton of carbon black. The national emission factor was
determined to be 3.178 tons of CO2 per ton of carbon black, which is 21% higher
than the default IPCC factor previously used. The uncertainty of the factor,
calculated using the IPCC Tier 1 methodology, was estimated at ±5%.
