The phrase "Net Zero" is widely used, but what does it mean? The balance between the amount of greenhouse gas produced and the amount removed from the atmosphere is known as net zero. When the amount we add equal the amount subtracted, we have reached net zero. However, how do we do this, and why does it matter?
The term "net zero" describes a situation where the atmospheric removal of greenhouse gases equals the number of greenhouse gases entering the atmosphere. The concept of net zero is crucial because, at least for CO2, this is the point at which global warming halts. The Paris Agreement emphasizes the need to achieve net zero and calls on nations to balance anthropogenic greenhouse gas emissions by sources and removals by sinks in the second half of this century.
It will be highly challenging to eliminate all emissions within the required timeframe. We'll probably need to ramp up removals in addition to making significant and broad reductions in emissions. Hence the "net
