usage restreint Presenting author: Greg Nemet University of Wisconsin-Madison Upscaling CDR Tuesday 4 June 2024 #StateofCDR | www.StateofCDR.org * À usage restreint Key messages Meeting the Paris Agreement's long-term temperature goal requires rapid greenhouse gas emission reductions and near-term scale-up of CDR Some CDR deployment is occurring, albeit at a low level To scale up CDR, innovative activity needs to intensify, of which we see robust evidence To increase CDR innovation and scale-up, policies are needed that create demand for carbon removals Public awareness of CDR has been rising Monitoring, reporting and verification (MRV) protocols are varied, proliferating and essential for scaling up CDR There continues to be a gap between the amount of CDR in scenarios that meet the Paris temperature goal and the amount of CDR in national proposals * À usage restreint Only a tiny fraction of all carbon dioxide removal results from novel methods • Total amount of carbon dioxide removal, split into conventional and novel methods (GtCO2/yr) * À usage restreint All scenarios use CDR 4 All scenarios use CDR in order to: ○ achieve net-zero CO2 emissions to stop temperature rise ○ counterbalance remaining levels of CO2 and other GHGs ○ achieve net-zero GHGs to lower temperature * À usage restreint 7-9 Gt per year of carbon removal is needed by 2050 with higher conventional CDR in more sustainable scenarios 5 • More sustainable 1.5-2°C scenarios scale up CDR at a similar pace as other scenarios • More sustainable scenarios tend to use more Conventional CDR and less Novel CDR • Sustainable mitigation strategies result in much stronger near and long-term emissions reductions * À usage restreint There is a gap between proposed levels of carbon dioxide removal and what is needed to meet the Paris temperature goal * À usage restreint Emerging diversity in indicators of CDR development, but, not yet seen in current deployment ornational proposals 7 National proposals of CDR Demonstration & upscaling Research & innovation * À usage restreint CDR demonstrations: Rapid expansion, mainly US, emerging international 8 • US $3.5b program for "DAC Hubs": 4 MT-scale DAC demos, 2 selected • Mission Innovation "CDR Launch Pad" program: coordination and knowledge sharing * À usage restreint Investment in CDR start-ups: down from peak, small portion of climate tech 9 • $856m in 2023 to 145 CDR start ups.

The first of a number of long awaited solar farms in the Northern Territory has finally opened this week, after being blocked from producing energy because of strict conditions on solar farm projects across the Top End over the last few years. Matt Thistlethwaite, Assistant Minister for Defence...
