Unfortunately, there aren't many options for green travel when you're going on holiday abroad - which leaves most of us needing to use an aeroplane to get to and from our destination.
Air travel emits as much carbon as 136million cars, at more than 350million tonnes per year.
One of the things you can do is carbon offsetting. This is where you pledge an amount of money, based on your carbon emission, to a project or charity dedicated to reducing/offsetting carbon.
I used an online calculator last week to work out the approximate carbon emission for my most recent holiday, in order to make a donation to an approved charity or project.
It estimated 0.333 tonnes of carbon was emitted, based on the flights and other modes of transport I used.
It then gave me different options on how my donation could be spent; from planting trees in the UK to helping fund community projects around the world.
Why is carbon dioxide so worrying?
In short, carbon dioxide is essential for all life but too much, and it causes climate change and it is linked to global dimming.
That said, carbon offsetting should be seen a last resort, after you've exhausted all other options to making sure your carbon footprint is as minimal as possible.
Here's some other ways you can help reduce and/or offset you carbon emissions:
