Many
other CDR events focus on a single approach (e.g. Direct
Air Capture, biochar, or land management) or single audience (e.g. academic, professional, etc.).
The major
other advantage of CDR from fossil fuel plant cleanup is that
air capture can be done anywhere and thus where the carbon can be both removed, used, and sequestered with the use even making the sequestration profitable.
In the near term, federal policy could: i) level the playing field between
air captured CO2 and fossil - fuel derived CO2 by providing subsidies or credits for superior carbon lifecycle emissions that account for recovering carbon from the atmosphere; ii) provide additional research funding into
air capture R&D initiatives, along with
other areas of carbon removal, which have historically been unable to secure grants; and iii) ensure
air capture is deployed in a manner that leads to sustainable net - negative emissions pathways in the future, within the framework of near - term national emissions reductions, and securing 2 °C - avoiding emissions trajectories.
The
other is to
capture fossil fuel emissions before they enter the atmosphere, or to suck them directly out of the
air — a technique known as carbon dioxide removal.
But innovators are also working on
other carbon removal methods: direct
air capture systems, agricultural techniques with the potential to sequester carbon in soils, and mining techniques that use minerals to sequester carbon directly from the atmosphere, for example.
But these costs for direct

Historically, direct
air capture has been largely framed as overwhelmingly expensive or impractical at commercial scale by carbon

capturing the dilute CO2 in the
air (exhaust streams of power plants and
other industrial facilities like oil refineries, steel mills, and cement plants have much more concentrated CO2 steams).
They add: «Direct

A lot of
other methods exist as well, such as directly
capturing CO2 from the
air with large panels coated with chemicals and even restore forests.
And since
capture from power plants and
other «point sources» is far less expensive than
air capture, it makes sense to focus CCS on power plants (fossil or bio) right now.
Unlike
other air pollutants, CO2 is an intended and necessary product of combustion, which means that CO2 emissions can not be «reduced» in the same way that SO2 can, for example, by eliminating impurities or scrubbing flue gas at power plants; rather, reducing emissions will likely require efficiency improvements or some method of CO2
capture for storage or reuse.
Only by carbon

The
other way to get to negative emissions is through something called Direct
