Methodology GAP Forum Manual (Vallack & Rypdal (2012) (collection & analyses) Limitations to data Emission factors: & analysis Average PM10 emission factors for residential wood and coal from the 2013 inventory (Wilton et al., 2015) Coal, CO and NOx were the multifuel burner emission factors (Wilton et al., 2015). Coal, SO2 was the GAP Forum Manual default value based on New Zealand fuel properties. (Vallack & Rypdal, 2012; MBIE, 2017) Wood, CO, NOx and SO2 were the wood burner emission factors (Wilton et al 2015). PM2.5 was assumed to be 100% of PM10 for wood and 88% of PM10 for coal.
