Summer travel season is here, but there are better ways to get there without destroying our planet! Catching a flight for even relatively short distances has become a common, everyday choice for many. But flying causes 5-10 times more pollution per passenger-mile than ground-based options!

Flying also puts the greenhouse gas emissions high up in our atmosphere, where they persist longer and have a greater impact on global climate disruption – a phenomenon known as “radiative forcing.”

As more and more of our campus community choose flights for business, conferences, recruiting, study abroad, etc. the emissions are really piling up. Indeed, flying now accounts for 8% of UofL’s total carbon footprint!

UofL Greenhouse Gas Emissions Sources 2016This year, consider greener, less sardine-like options that don’t involve the incivility of suspicious TSA agents and mandatory shoe removal! Try a better way! Consider a video- or teleconference – maybe you don’t need to sustainabilitytravel at all! Share a ride with others in a carpool. You can easily setup carpools, find Louisville’s inter-city connections and explore all your options for getting around with Cardinal Directions!
