Six commercially viable ways to remove CO2 from the atmosphere and/or reduce CO2 emissions

Environmental Sciences Europe

Table 1 Estimated order of magnitude of CO ₂ capture and/or emission reduction and money involved

	CO₂capture or emission reduction	Cost or benefit
Unit	1 Million ton	1 Million euro
Options
Nickel farming	1 to 50	0 to +200
Biodiesel from diatoms	50 to 1,000	+10 to +500
Quenching forest fires	100 to 1,000	+200 to + 2,000
Supergreen energy	20 to 1,000	+50 to + 5,000
Coastal protection	10 to 1,000	-1 to + 100
Olivine in high-energy waters	25,000	-500,000^a

^aIf the figure of 500 billion euro of costs for the option in the last row is compared to the cost of the CCS-option, the deficit changes into a benefit of 700 billion euro cf.[12].
