Other processes that enhance CO2 removal include ocean fertilisation, ocean alkalinity enhancement and marine/terrestrial photosynthetic conversion, which
Carbon sequestration is the act of capturing carbon dioxide (CO2) from the atmosphere and storing it in plants, soils, and the ocean. However practices such as tilling, which disturbs the soil, can release this stored carbon into the atmosphere. Growers can harness biological carbon sequestration in several ways, such as planting more trees, enhancing soil health, practicing regenerative agriculture, and preserving peatlands. Some practices that enhance soil health also boost its ability to capture and store carbon. Carbon sequestration is the process of capturing CO2 from the atmosphere and then storing it in a safe place. Technological carbon sequestration also helps limit global warming by storing CO2 before it is released into the atmosphere, preventing its contribution to climate change. Syngenta and Brazilian farmers are collaborating to implement regenerative agriculture practices, like cover cropping and no-till farming, for sustainable and profitable corn seed production.
Carbon removal strategies include familiar approaches like growing trees as well as more novel technologies like direct air capture, which scrubs CO2 from the air after which it can be sequestered underground. **The latest** **climate model scenarios** **show that in addition to substantial and rapid emissions reductions, large-scale carbon removal will be needed to keep temperature rise to 1.5 degrees C.** The amount of carbon removal ultimately needed will depend on how quickly we reduce emissions in the near term as well as the magnitude and duration of any increase above 1.5 degrees C, known as overshoot. Some management approaches that can increase carbon removal by trees and forests include:. Cost estimates for DAC with sequestration vary: voluntary purchases of carbon removal credits from direct air capture range from $100 to more than $2,000 per metric ton of CO2 depending on the technology, energy source, use of policy incentives, and other factors.
The new process uses heat to transform common minerals into materials that permanently sequester atmospheric carbon dioxide.
Carbon sequestration refers to the storage of carbon dioxide (CO2) after it is captured from industrial facilities and power plants or removed directly from
Different options to try to reduce overall CO2 emissions are being investigated, but the main way to reduce CO2 emissions from large industrial sources is called carbon capture and storage, or CCS. CO2 can be captured from large sources, such as power plants, natural gas processing facilities and some industrial processes. Thus even though CCS would increase the cost of electricity from a biomass power plant, customers would know that electricity produced there would actually be reducing the CO2 content of the atmosphere, making this technology particularly attractive. The concept is to capture CO2 produced by burning coal in power stations, compress it, pipe it away from the plant and then store it deep underground. Most co-firing power plants burn solid biomass like wood and agricultural waste along with coal, but some can burn a mix of natural gas and biogas. A fossil-fuel power plant is one that burns fossil fuels such as coal, natural gas or petroleum (oil) to produce electricity.

As with all kinds of carbon removal, it’s not clear what enhanced weathering would cost on a large scale, but Gurgel’s research suggests it could be cheaper than DAC and probably doesn’t need as much dedicated land as BECCS. But although enhanced weathering may turn out to be both reasonably cost-efficient and reasonably land-efficient (at least by carbon removal standards), it’s not very *rock*-efficient. “Integrated assessment of carbon dioxide removal portfolios: land, energy, and economic trade-offs for climate policy.” *Environmental Research Letters* 20 (2025).

Ho, Nature: "Carbon dioxide removal is not a current climate solution—we need to change the narrative". Listen to this episode of MIT's "Today I Learned: Climate" podcast on carbon dioxide removal. Enhanced rock weathering is a strategy to help address climate change by taking carbon out of the air and storing it in rocks.
