Did you know that flying a family of four first class from Chicago to Orlando’s Disney World likely results in more carbon dioxide emissions than both parents would emit in a year’s worth of community to work every day by car?!  That’s according to my trusty manual on living a low-carbon lifestyle, Cooler, Smarter: Practical Steps for Low-Carbon by The Union of Concerned Scientists.

So what’s a carbon conscious air traveler to do besides wait for low-carbon technologies, super fuel efficiency, or other innovations to emerge?  Well, plenty! In this blog we explore purchasing carbon offsets to reduce your transportation impacts due to air travel.

Before we go there, we should say that choosing direct flights, avoiding short regional flights, or opting for bus or train travel will make a significant difference in your CO2 emissions. However, if air travel is necessary, purchasing carbon offsets is a great option with minimal budget impacts.

Carbon Offsets In a Nutshell

Carbon offsets are financial contributions that you can make to projects that contribute to reductions in CO2 emissions. These types of projects cannot pay for themselves which makes carbon offset purchases so important. Some examples are:

  • Forest conservation

  • Wind, solar, or hydro power generation

  • Methane trapping at landfills

  • Anaerobic digestion of animal waste/methane trapping

  • Distributing clean burning stoves to India

Buyer Beware

The business of selling carbon offsets is a voluntary and unregulated market with a variety of industry standards. So it’s important that you look beyond the price tag and also make sure that the purchasing company is certified by at least one (if not more) of the well-respected, third-party verifiers. These verifiers include the Gold Standard, the Verified Carbon Standard, the Climate Action Reserve, the American Carbon Registry, and the United Nations’ Clean Development Mechanism.

A certified carbon offset must achieve, at minimum the following:

  • Have a reputable third-party verification. This means that CO2 reductions can be quantified, monitored, and reported by third party auditors.

  • Be a permanent purchase. Each offset should have a unique serial number and extend through the useful life of the project. For example, you wouldn’t want to invest in a tree planting project that is then sold to a timber company.

  • Add something to CO2 reduction efforts. If it’s already a requirement to implement the project, your carbon offset purchase is not providing an incentive.

Our Top Four Provider Picks

 The first thing you’ll want to do is determine how many carbon offsets you want to buy. Many airlines and offset purchasing sites will have carbon calculators on their websites. However, the International Civil Aviation Organization (ICAO) has a pretty simple calculator that is transparent about the methodologies and assumptions used in their calculations. You can find their calculator here:

After you have an idea of quantity, then you’ll need to find a company that you can trust. We recommend the following carbon offset providers:
