Definition 

The Intergovernmental Panel on Climate Change (IPCC) defines Negative Emission Technologies (NETs) as anthropogenic activities that remove CO2 from the atmosphere and durably store it. NETs are in reality a range of technologies from nature-based practices, such as forestation, soil carbon sequestration and wetland restoration, to technological alternatives such as enhanced weathering, bioenergy with carbon capture and storage, and direct air capture and storage.
