Complete restoration of deforested areas is unrealistic, yet 100 GtC
carbon drawdown is conceivable because: (1) the human - enhanced atmospheric CO2
level increases
carbon uptake by some vegetation and soils, (2) improved agricultural practices can convert agriculture from a CO2 ource into a CO2 sink [174], (3) biomass - burning power plants
with CO2
capture and storage can contribute to CO2 drawdown.
RD&D on
carbon capture and storage (CCS) technology is needed, especially given our conclusion that the current atmospheric CO2
level is already in the dangerous zone, but continuing issues
with CCS technology [7], [244] make it inappropriate to construct fossil fuel power plants
with a promise of future retrofit for
carbon capture.
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 problem is that we have got enough coal to burn for several hundred years, even
with a growing world population
with higher aspirations, and if we convert all of that coal, and therefore burn it, without
capturing the
carbon dioxide we would probably be able to raise the
carbon dioxide
level ultimately to around 1,500 parts per million.
