Is flying or driving higher for the atmosphere?


With regards to local weather change and journey, it generally appears that we as people are extra in tune with learn how to mitigate our small impacts (like swapping out on a regular basis objects on a trip) than our massive ones (like minimizing the huge carbon footprint we create simply to get to that trip). However the latter is actually essential: In keeping with the United Nations World Tourism Group, tourism is chargeable for about 5 % of all carbon dioxide (CO2) emissions on the earth — and transportation accounts for 75 % of that.
