Once you know your footprint, you can work to offset it.
A lot of the calculators above include ways to offset your emissions through various methods - these range from planting and protecting forests around the world, to funding new clean energy projects that reduce the global reliance on fossil fuels.
Tell your friends and family, challenge them to do the same.
Better yet: if you can afford it, why not offset their emissions for them? A slightly different birthday or Christmas gift idea for you there.
Why is this important?
Offsetting our emissions isn't the solution to climate change, we need to work to reduce our overall emissions in the first place.
Instead, offsetting should be seen as a vote of support for green initiatives - be that through protecting forests and vital habitats that help store carbon, or supporting clean energy projects across the globe.
Offsetting is a good introduction to a more carbon negative attitude - for every gram of CO2 we put into the atmosphere, we should ensure we can take 2 grams out.
