When we heat our homes or drive our cars using fossil fuels, carbon dioxide and other greenhouse gases (GHGs) are released into the atmosphere. These are often referred to as emissions. Some of these emissions are absorbed by carbon sinks. Carbon sinks are natural systems, like forests or wetlands, that suck up and store carbon from the atmosphere. Net-zero refers to the balance between the amount of emissions produced and the amount that can be absorbed by these carbon sinks.
To achieve net-zero, we need to reduce the amount of emissions that are released into the atmosphere so that it is equal to what can be absorbed by our natural environment. Think of it as a two-sided weighing scale!
