In carbonr: Calculate Carbon-Equivalent Emissions

Calculate CO2e emissions from ferry journeys

Description

A function that calculates CO2e emissions between ferry ports.

Usage

ferry_emissions(
  from,
  to,
  via = NULL,
  type = c("Foot", "Car", "Average"),
  num_people = 1,
  times_journey = 1,
  include_WTT = TRUE,
  round_trip = FALSE
)

Arguments

from	Port code for the port departing from. Use seaport_finder to find port code.
to	Port code for the port arriving from. Use seaport_finder to find port code.
via	Optional. Takes a vector containing the port code that the ferry travels through. Use seaport_finder to find port code.
type	Whether the journey is taken on foot or by car. Options are "Foot", "Car", "Average".
num_people	Number of people taking the journey. Takes a single numerical value.
times_journey	Number of times the journey is taken.
include_WTT	logical. Recommended TRUE. Whether to include emissions associated with extracting, refining, and transporting fuels.
round_trip	Whether the journey is one-way or return.

Details

The distances are calculated using the Haversine formula. This is calculated as the crow flies.

Value

Returns CO2e emissions in tonnes for the ferry journey.

Examples

# Emissions for a ferry journey between Belfast and New York City
seaport_finder(city = "Belfast")
seaport_finder(city = "New York")
ferry_emissions(from = "BEL", to = "BOY")
