Net zero refers to the balance between the amount of greenhouse gases that are emitted into the atmosphere and the amount that are removed from the atmosphere. A net zero carbon dioxide (CO2) emissions target means that an organization, region, or country is seeking to achieve zero net CO2 emissions by balancing its emissions with an equivalent amount of CO2 removal. This can be achieved through a combination of reducing emissions and implementing measures to remove CO2 from the atmosphere, such as planting trees or using carbon capture technologies. Achieving net zero emissions is seen as an important step in mitigating the impacts of climate change and reducing the risk of negative environmental and health outcomes.
