FUGITIVE EMISSIONSFor fugitive emissions from mining, processing, storage and transportation of coal, the 2019 Refinement includes
guidance on emissions of carbon dioxide (CO2) emissions from underground and surface mines.
For fugitive emissions from oil and natural gas systems, the 2019 Refinement includes emission factors
representative of current practice, including for unconventional oil and gas exploration, and methods and emission
factors for abandoned wells.
For fuel transformation, the 2019 Refinement includes a new section on fugitive emissions from fuel transformation,
including methods for fugitive emissions from charcoal production, coke production, coal to liquids and gas toliquids.
