In a study led by University of Oxford, scientists have calculated for the first time that every year, about two billion tonnes of carbon dioxide (CO₂) are being removed from the atmosphere.
As a reference, the authos estimate the current CO₂ emissions per year from fossil fuels and cement to be around .......... of 36.6 GtCO2.
This means that successful removal would represent slightly over 5% of what is being emitted.
About 99.9% of this CO₂ removal occurs through “conventional means”, such as restoring previously deforested ones, creating new forests, better managing soils and optimize wood usage and products. Basically forests.
On the other hand, representing the remaing 0.1%, we have Carbon Dioxide Removal (CDR), that involves capturing CO₂ from the atmosphere and storing it for decades to millennia on land, in the ocean, in geological formations or in products. Basically carbon capture and storage.
Specially in the developed countries - or countries without much land to restore forests - innovation in CDR has expanded substantially, exemplified by R&D, in patents and capacity investment. And CDR has been subject of increasing public attention.
Last December, the US Department of Energy committed $3.7 billion (€3.4bn) to finance CO₂ removal projects. The European Union, meanwhile, aims to capture five million tonnes of CO2 annually by 2030. And in 2022 we also had news about the "OPEC for rainforests", congregating Brazil, Indonesia and the Democratic Republic of Congo (DRC).
"We are still at the very start", adds co-author Jan Minx, of the Mercator Research Institute on Global Commons and Climate Change in Germany.
