Emission factors
The emission factors (EFs) used for Burundi's national inventory are mainly those of Burundi. Level 1 default values (Tier 1) from the 2006 IPCC Guidelines and its 2019 refinements. For indirect pollutants, the EMEP/CORINAIR (2023) guide was preferred.
Emission factors used in Burundi
This sector covers stationary combustion (industry, household) and mobile combustion (transport).
