Description

A function that calculates CO2e emissions on a journey on land.

Usage

vehicle_emissions(
  distance,
  units = c("miles", "km"),
  num = 1,
  vehicle = c("Cars", "Motorbike"),
  fuel = c("Petrol", "Diesel", "Unknown", "Battery Electric Vehicle",
    "Plug-in Hybrid Electric Vehicle"),
  car_type = c("Average car", "Small car", "Medium car", "Large car", "Mini",
    "Supermini", "Lower medium", "Upper medium", "Executive", "Luxury", "Sports",
    "Dual purpose 4X4", "MPV"),
  bike_type = c("Average", "Small", "Medium", "Large"),
  TD = TRUE,
  include_WTT = TRUE,
  include_electricity = TRUE,
  owned_by_org = TRUE
)

Value

Tonnes of CO2e emissions per mile travelled.

Arguments

distance

Distance in km or miles of the journey made (this can be calculated with other tools, such as google maps.).

units

Units for the distance travelled. Options are "km" or "miles".

num

Number of vehicles used.

vehicle

Vehicle used for the journey. Options are "Cars", "Motorbike".

fuel

Fuel type used for the journey. For car, "Petrol", "Diesel", "Unknown", "Battery Electric Vehicle", "Plug-in Hybrid Electric Vehicle" are options. ##' "hybrid electric" and "battery electric" account for electricity kWh emissions.

car_type

Size/type of vehicle for car. Options are c("Average car", "Small car", "Medium car", "Large car", "Mini", "Supermini", "Lower medium", "Upper medium", "Executive", "Luxury", "Sports", "Dual purpose 4X4", "MPV"),. Small denotes up to a 1.4L engine, unless diesel which is up to 1.7L engine. Medium denotes 1.4-2.0L for petrol cars, 1.7-2.0L for diesel cars. Large denotes 2.0L+ engine.

bike_type

Size of vehicle for motorbike. Options are "Small", "Medium", "Large", or "Average". Sizes denote upto 125cc, 125cc-500cc, 500cc+ respectively.

TD

logical.Whether to account for transmission and distribution (TD) for electric vehicles (only car and van)

include_WTT

logical. Well-to-tank (include_WTT) - whether to account for emissions associated with extraction, refining and transportation of the fuels (for non-electric vehicles).

include_electricity

logical. Whether to account for ... for electric vehicles (car and van).

owned_by_org

logical. Whether the vehicle used is owned by the organisation or not (only for car, motorbike).

Examples

# Emissions for a 100 mile car journey
 vehicle_emissions(distance = 100)

# Emissions for a 100 mile motorbike journey where the motorbike is 500+cc
 vehicle_emissions(distance = 100, vehicle = "Motorbike", bike_type = "Large")
