ef_cetesb: Emissions factors for Environment Company of Sao Paulo, Brazil (CETESB) 2017

Description

ef_cetesb returns a vector or data.frame of Brazilian emission factors.

Usage

ef_cetesb(p, veh, year = 2017, agemax = 40, full = FALSE,
  project = "constant")

Arguments

p

Character; Pollutants: "COd", "HCd", "NMHCd", "CH4", "NOxd", "CO2", "PM", "N2O", "KML", "FC", "NO2d", "NOd", "gD/KWH", "gCO2/KWH", "RCHOd", "CO", "HC", "NMHC", "NOx", "NO2" ,"NO", "RCHO" (g/km). The letter 'd' means deteriorated factor. Also, evaporative emissions at average temperature ranges: "D_20_35", "S_20_35", "R_20_35", "D_10_25", "S_10_25", "R_10_25", "D_0_15", "S_0_15" and "R_0_15" where D means diurnal (g/day), S hot/warm soak (g/trip) and R hot/warm running losses (g/trip).

veh

Character; Vehicle categories: "PC_G", "PC_FG", "PC_FE", "PC_E", "LCV_G", "LCV_FG", "LCV_FE", "LCV_E", "LCV_D", "SLT", "LT", "MT", "SHT", "HT", "UB", "SUB", "COACH", "ARTIC", "M_G_150", "M_G_150_500", "M_G_500", "M_FG_150", "M_FG_150_500", "M_FG_500", "M_FE_150", "M_FE_150_500", "M_FE_500", "CICLOMOTOR", "GNV"

year

Numeric; Filter the emission factor to start from a specific base year. If project is 'constant' values above 2017 and below 1980 will be repeated

agemax

Integer; age of oldest vehicles for that category

full

Logical; To return a data.frame instead or a vector adding Age, Year, Brazilian emissions standards and its euro equivalents.

project

haracter showing the method for projecting emission factors in future. Currently the only value is "constant"

Value

A vector of Emission Factor or a data.frame
