On top of drastic emissions cuts, IPCC finds large-scale CO₂ removal from air will be “essential” to meeting targets

"Large-scale deployment of carbon dioxide removal (CDR) methods is now
“unavoidable” if the world is to reach net-zero greenhouse gas emissions,
according to this week’s report by the Intergovernmental Panel on Climate
Change (IPCC).

The report, released on Monday, finds that in addition to rapid and deep
reductions in greenhouse emissions, CO₂ removal is “an essential element of
scenarios that limit warming to 1.5℃ or likely below 2℃ by 2100”.

CDR refers to a suite of activities that lower the concentration of CO₂ in the
atmosphere. This is done by removing CO₂ molecules and storing the carbon in
plants, trees, soil, geological reservoirs, ocean reservoirs or products
derived from CO₂.

As the IPCC notes, each mechanism is complex, and has advantages and pitfalls.
Much work is needed to ensure CDR projects are rolled out responsibly."
