However, research has shown that even with efficiency gains in each region, food, energy and climate needs can result in competition for land.
A profoundly changing climate could also limit the potential, with only 1.2C of warming.
“If warming continues – and all indications say it will – it will be even more difficult to maintain current levels of conventional CDRs because they will be affected by drought, storms, pests and other impacts,” said co-author Oliver Geden Said, a senior fellow at the German Institute for International and Security Affairs and an IPCC lead author.
This means that new CDR methods will have to pick up the slack.
To keep warming under 2C, deployment of these nascent technologies would need to increase 30-fold by 2030 and more than 1,000-fold by 2100, according to an Oxford University-led report.
The 1.5C target will need to be scaled up even more rapidly.
