Fast growing research on negative emissions. The 1.5☌ Target, Political Implications, and the Role of BECCS (Oxford Univ. A detailed quantitative report that demonstrates the need for negative emission.įuss, S. The Emissions Gap Report 2017 (United Nations Environment Programme 2017). Popular negative-emission approaches include bioenergy combined with carbon capture and storage (BECCS), alternative and adjusted agricultural practices such as biochar production and utilization, ambient air capture and utilization, and accelerated natural mineral weathering via electrogeochemical methods coupled with H 2 generation 1, 5.ĭen Elzen, M. To meet the 2 ☌ target, many studies suggest it is necessary to balance emission reductions with CO 2 removal and the deployment of negative emission methods, because most models indicate it is impossible to reach 1.5 ☌ with a 50% chance without significant negative emissions 2, 3, 4. The United Nations Environment Programme (UNEP) recently analysed the major emission gap to achieve this goal, but it found current state pledges cover no more than one third of the needed emission reductions 1. The Paris Agreement on Climate Change aims to hold the global average temperature increase below 2 ☌, and special efforts are made to limit the increase to 1.5 ☌ by 2100 relative to pre-industrial levels.
