1.B - Fugitive Emissions from fuels

Last updated on 18 Mar 2020 09:18 (cf. Authors)

Short Description


During all stages of fuel production and use, from extraction of fossil fuels to their final use, fuel components can escape or be released as fugitive emissions.

While NMVOC, TSP and SOx are the most important emissions within the source category solid fuels, fugitive emissions of oil and natural gas include substantial amounts of NMVOC and SOx.

1.B - "Fugitive emission from fuels" consist of following sub-categories:


Solid Fuels

production and transformation from hard-coal and lignite


Liquid and gaseous Fuels

crude oil, liquid oil products, natural gas, town gas, refinery gas, venting and flaring



This chapter is included in "liquid and gaseous fuels".

Proportional share of fugitive emissions concerning emissions of the energy sector and national total amounts

pollutant fugitive amount in year 2018 share within the energy sector share within the national inventory
NOx 1,77 kt 0,18% 0,14%
NMVOC 43,38 kt 20,65% 4,17%
SOx 5,98 kt 2,72% 1,54%
PM2.5 0,93 kt 1,61% 0,89%
PM10 4,60 kt 5,94% 2,08%
TSP 14,00 kt 13,90% 4,10%

Recalculations covering the past two years have been carried out as a result of the provisional nature of a number of statistics in this area.

For pollutant-specific information on recalculated emission estimates reported for Base Year and 2015, please see the pollutant specific recalculation tables following chapter 8.1 - Recalculations.
