Enhancing CO2 sequestration by plants to reduce carbon footprint
This research integrates process optimization, sustainable practices, and technological innovations to augment plants' natural CO 2 absorption.

Biological carbon sequestration is natural storage of carbon dioxide. This includes storage in plants (naturally done through photosynthesis)
The new process uses heat to transform common minerals into materials that permanently sequester atmospheric carbon dioxide.
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.
Reforestation, cultivating coral reefs as carbon sinks and regenerative agriculture all hold great promise.
Two solutions currently exist: those known as nature-based solutions (NBS), and carbon capture and storage (CCS), which uses technology to

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). MIT Climate Portal: "How much carbon dioxide would we have to remove from the air to counteract climate change?". 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.
