An illustration of plane pollution. (The WorldPost)
According to former U.N. climate chief Christiana Figueres, we have only three years left in which to “bend the emissions curve downward” and forestall a terrifying cascade of climate-related catastrophes, much worse than what we’re already experiencing. Realistically, is there anything that you or I can do as individuals to make a significant difference in the short time remaining?
The answer is yes, and the good news is it won’t cost us a penny. It will actually save us money, and we won’t have to leave home to do it. Staying home, in fact, is the essence of making a big difference in a big hurry. That’s because nothing that we do pumps carbon dioxide into the atmosphere faster than air travel. Cancel a couple long flights, and you can halve your carbon footprint. Schedule a couple, and you can double or triple it.
Atmosfair is a German public interest group that recommends limiting your air travel to about 3,100 miles per year — if you live in Los Angeles, that’s one round-trip flight to Mexico City. If you must exceed that limit, Atmosfair invites you to compensate by sending conscience money on a prorated basis to support climate stabilization efforts around the world. Last fall, having accepted an invitation to speak in Morocco, I used this online calculator to determine the carbon cost of my trip. My seats alone on the round-trip flights from Los Angeles to Casablanca (with a layover in Paris) helped emit about 8,400 pounds of carbon dioxide, prorated, into the atmosphere. Double that because my wife accompanied me. In sum, our seats alone on the planes to and from Morocco helped unload about 16,800 pounds of carbon dioxide. And this, of course, was just a small fraction of the emissions cost of the flight as a whole.
To put this into perspective, my wife’s and my annual carbon footprint in Orange County, California — counting gas, electricity, transportation and waste disposal — is about 33,000 pounds, according to the carbon footprint calculator of the U.S. Environmental Protection Agency. (To put that total into further perspective, the average Indian’s annual carbon footprint is just 3,000 pounds.) By taking one optional international trip that helped emit about 16,800 pounds of carbon dioxide into the atmosphere, my wife and I increased our 2016 carbon footprint by more than a third. The harm we did with one international trip surely neutralized any good that we did all year as recyclers, eco-consumers and financial contributors to environmental organizations.
To put our flights’ 16,800 pounds of carbon dioxide further into perspective, the average American generates about 1,300 pounds of carbon dioxide a year through beef consumption. Minute by minute, mile by mile, nothing that we do causes greater or more easily avoidable harm to the environment than flying, which more often than not is optional or merely recreational.
