CarbonBrief: Guest post: Combining renewables with direct air capture for ‘net negative’ emissions

The recent special report from the Intergovernmental Panel on Climate Change (IPCC) has shown that limiting global warming to 1.5C is still within reach, but that it requires rapid and stringent cuts to global CO2 emissions. Modelling pathways that achieve the Paris Agreement goals rely on swift decarbonisation of the power sector and scaling up of “negative emissions” – an array of techniques to remove CO2 from the atmosphere and store it on land or underground.
