Why limit overseas travel? International air travel is one of the single biggest and easiest sources of carbon emissions to reduce. Kiwis love to travel the world. That love of travel is leading to some big carbon emissions. A return flight to London from Auckland can emit up to 7 tonnes of CO2, and a Wellington to Auckland return trip 0.276 tonnes. And people remember we’re aiming to reduce our carbon footprints down from 7.465 tonnes to 3 tonnes- not increase it! That means the staycation is your vacation of choice.
