NOx, SOx, and other significant air emissions
Breakdown of air emissions by activities
More than 80% of SO2 emissions were produced at our refineries.
The increase in NMVOC emissions was due to the inclusion of ROGCI assets as of January (2015 figures include ROGCI from acquisition in May).
Intensity of major air emissions
Atmospheric emissions per ton of crude oil processed at our refineries and per barrel of oil equivalent (boe) produced by our Exploration and Production assets were as follows:
|Tons SO2 / thousands of tons of oil processed||0.631||0.532||0.563|
|Tons NOx / thousands of tons of oil processed||0.416||0.411||0.314|
|Tons NMVOC / thousands of tons of oil processed||0.353||0.349||0.354|
EXPLORATION AND PRODUCTION
|Tons SO2 / thousands of boe produced||0.059||0.031||0.026|
|Tons NOx / thousands of boe produced||0.190||0.114||0.094|
|Tons NMVOC / thousands of boe produced||0.301||0.181||0.188|
- The intensive figures were calculated in due consideration of the gross production of our managed assets, since the air emissions reported considers 100% of consumption of these assets, regardless of the percentage held by Repsol.
