Fly Less
If you regularly find yourself stuck in airports, you should think twice about how important those flights actually are. There may be times when you feel you do need to fly - seeing relatives, exploring far away places, or attending a critical work event. That’s okay! But there are also times when you can choose not to fly, and feel good about it.
Talk with your co-workers and clients about why flying less is important to you, and find ways to change the travel policies. Choosing a video conference instead of a flight can save everyone time and money, and helps reduce stress. Cutting just one return economy class flight between New York and Los Angeles could save as much as 0.6 metric tonnes of CO2 – that’s the same amount of emissions that the average person in Bangladesh produces in an entire year! Not everyone has the privilege of flying, but if you fly frequently, taking a few less flights is one of the best ways to dramatically reduce carbon pollution.

By avoiding emissions from business air travel, telepresence can reduce emissions by 1–3.8 gigaton of carbon dioxide over 30 years.

Nonstop flights and the use of fuel-efficient aircraft or airlines are likely to yield fewer emissions than alternatives on the same route.

The risk of venous thromboembolism is increased 2 to 3-fold after long-haul flights (>4 h) and also with other forms of travel involving prolonged seated immobility

While a smaller portion of total travel, regional flights have the highest carbon intensity per passenger kilometer.
Impact metric calculations
To determine the carbon emission reduction estimates related to switching to flying less, the following calculations were performed:
Baseline Air Travel: (# of flights/month) x (country-specific kg CO2e/mile) x (miles/flight) = kg CO2e / month
Lower Emitting Alternative: (# of alternate travel trips/month) x (country-specific kg CO2e/mile) x (miles/alternate transit) = kg CO2e / month
Total: Baseline Air Travel – Lower Emitting Alternative = kg CO2e/month
