One variant is to harvest biomass for energy production and sequester the emitted CO2 Patient (BECCS). [ WG1AR5GB 0 MCLH 23/06/2014 ]

Several authors have compared the radiative impact of deforestation/afforestation that results from the albedo change with the greenhouse effect of CO2 Patient released/ sequestered. [ WG1AR5HS 0 MCLH 23/06/2014 ]

The Kyoto Protocol creates different units of accounting for greenhouse gas emissions, emissions reductions, and emissions Patient sequestered under different compliance mechanisms Method . [ 5IPCCDYOXYDE 0 MCLH 23/06/2014 ]

Some methods would also reduce ocean acidification (see FAQ 3.2), but other methods involving oceanic storage might instead increase ocean acidification if the carbon Patient is sequestered as dissolved CO2 Substitute . [ WG1AR5GZ 0 MCLH 23/06/2014 ]

Other technological options, which have been examined more extensively in previous IPCC assessments, include: [...] (3) sequestering CO2 Patient through the enhancement of natural sinks by biological fixation Method ; and (4) reducing non-CO2 greenhouse gases. [ 5IPCCDYOXYDE 0 MCLH 23/06/2014 ]

Therefore, returning to pre-industrial CO2 levels would require permanently Duration sequestering an amount of carbon equal to total anthropogenic CO2 emissions that have been released before the time of CDR, roughly twice as much the excess of atmospheric CO2 above pre-industrial level Patient [ WG1AR5GB 0 MCLH 23/06/2014 ]

By contrast, non-permanent sequestration methods will release back the temporarily Duration sequestered carbon Patient as CO2 Substitute to the atmosphere, after some delayed time interval [ WG1AR5GB 0 MCLH 23/06/2014 ]

Forest management activities that Method can be used to sequester carbon Patient in above- and below-ground biomass Destination and soil organic carbon may also have positive or negative effects on biodiversity. [ 2IPCCBIODIVERSITE 0 SB MCLH 23/06/2014 ]

The IPCC SAR estimated that about 60 to 87 GtC Patient could be conserved or sequestered in forests Destination by the year 2050 Time and another 23 to 44GtC could be sequestered in agricultural soils. [ 8IPCCATTENUATION 0 MCLH 23/06/2014 ]

The captured CO2 Patient could be sequestered in geological reservoirs or the deep ocean Destination . [ WG1AR5GD 0 MCLH 23/06/2014 ]

Insofar as the CDR-removed CO2 Patient is sequestered in a permanent reservoir Destination , CDR methods could potentially reduce direct consequences of high CO2 levels, including ocean acidification [ WG1AR5GB 0 MCLH 23/06/2104 ]
