Unless you’re running across the country à la Forest Gump, traveling can induce a certain amount of green guilt. Cars burn through gas; cruise ships generate up to 11 million gallons of wastewater each day; and air travel spews greenhouse gases into the sky. Happily, many domestic airlines now sponsor carbon offset programs, which let passengers calculate their carbon footprint and tack a small charge onto plane tickets to neutralize the journey’s impact on the earth. The offsets cost as little as $3, depending on the flight’s length, and support valuable emissions reduction projects, such as planting trees in Louisiana or funding projects that reduce methane levels in landfills across the U.S. To shrink your footprint, scan our roundup of stateside offset programs before booking your next flight.
Delta Air Lines
Delta pioneered domestic carbon offset programs in 2007, and its current work with The Nature Conservancy encourages flyers to fund environmental projects around the world. Today through May 22, Delta will match all carbon offset donations made through The Nature Conservancy, up to $25,000.
JetBlue’s program through Carbonfund.org supports three U.S. emissions reduction efforts: a wind farm in Wingate, Texas; a waste management project in Rodam, N.Y.; and a reforestation effort in the Tensas River Valley in Louisiana. Offsets start at $5 for flights shorter than 2,500 miles.
Virgin America also works with Carbonfund.org, but it skips tree-planting in favor of two projects that fund truck stop electrification and dairy farm biodigesters. Offsets start at $5 for flights shorter than 2,500 miles.
