Passengers flying from San Francisco International Airport have a new way to potentially undo the environmental damage caused by their flights.
Three kiosks recently unveiled at the airport allow flyers to pay a voluntary fee to counteract their plane's carbon emissions.
Travelers enter their flight's details to find out how many pounds of carbon dioxide they are responsible for offsetting. The machines then charge $13.50 per ton.
A round-trip from SFO to John F. Kennedy Airport in New York would cost $23.42 per person. A one-way trip to Los Angeles International Airport would cost $1.75.
Of the $13.50, $12 funds reforestation at a 24,000-acre forest preserve in Mendocino County. The remaining $1.50 supports San Francisco environmental programs.
