This solution is currently being employed. It was presented in the story Suck it Up in our anthology.
About carbon-capturing trees
We know that stopping fossil fuel combustion is not good enough, we also have to capture carbon from the atmosphere and lock it up forever. The planting of real trees which capture carbon will make a tremendous difference in the fight against climate change. “Fake” trees using a chemical resin as a carbon sponge is cutting-edge, nascent technology with theoretical possibilities.
CCS (Carbon Capture and Storage) is a well-established oil field technology used for enhanced oil recovery. It is still a relatively high-cost solution. The story Our Shared Storm describes a scheme to divert much more investment into the sector. All and every method to increase funding in this sector is required.
This video explains how carbon capture technology works. This article featuring an interview with Prof Klaus Lackner also explains the technology which is being trialled in Arizona (USA).

|Climate impact: tonnes of carbon saved/removed||CCS – carbon capture and storage – can already dispose of millions of tonnes of CO2 per year. It needs to be ramped up 1000 fold, which is a lot easier than the ramp required of other technologies.|
|Climate adaptation-resilience||CCS is a foundation technology that needs to be widely deployed at every suitable site as soon as possible.|
The oil and gas industry will eventually transmogrify into the CO2 disposal industry. It will be bigger than the existing O&G industry & needs to be boldly supported.
|Social justice i.e. addresses inequalities, diversity, inclusion||Low.|
|Cost of action needed to progress goal||Substantial costs. Disposal costs of 100s $ per tonne need to be swallowed and supported by carbon taxes.|
|Which location is the solution most needed/applicable||Existing oil and gas fields.|
|Risk||Some risk of leaks but not in all locations.|
|Feasibility||It is already a reality but it requires expanding rapidly.|
Interested in progressing this solution further?
|Actions for policymakers||National and eventually international carbon taxes.|
End to hydrocarbon subsidies.
Direct subsidy for CCS in some cases.
Massive reforestation efforts as the natural solution to carbon capture is a must.
Land preservation efforts to prevent deforestation are essential.
|Actions for funding bodies||Provide full funding for dozens of projects in multiple locations around the world.|
Fund research and development of carbon capture techniques.
|Actions for business||Adopt real prices of carbon and commit to 100% disposal.|
|Actions for public||Pay extra for energy.|
