Net zero or real zero? Assessing the carbon dioxide removal in net zero pledges
Net zero or real zero? Assessing the carbon dioxide removal in net zero pledges.
In our latest analysis of net zero targets, we find an increasing number of governments disclose plans on the type and scope of carbon dioxide removal within their borders to meet their longer-term targets — but detailed information across government’s plans remains scarce.
Across 28 countries accountable for over 80% of global emissions, these plans aim for combined forest sinks of 4.7–5.7 GtCO2e, which would represent 12–15% of their 2019 emissions. Eight of these countries also plan for engineered carbon dioxide removals (such as direct air carbon capture) of 0.7–1.3 GtCO2e. With estimated costs for engineered CDR at a scale of up to USD 400 per tonne CO2, governments would need to invest hundreds of billions a year for these removals.
