What is carbon dioxide removal and how does it work? * What is carbon dioxide (CO2) removal? * Which carbon dioxide removal method is best ? * What is carbon dioxide (CO2) removal? * Which carbon dioxide removal method is best ? In this article, we'll explain what carbon dioxide removal is, how it works, and 6 ways carbon dioxide can be captured from the atmosphere. ## What is carbon dioxide (CO2) removal? Like other organic methods of carbon dioxide removal, plants drink up carbon dioxide through the process of photosynthesis. Wetlands are experts at storing carbon in soil, as they **remove carbon dioxide from the atmosphere by capturing carbon in plant roots and bodies just like forests.**. ## Which carbon dioxide removal method is best ? If reading this article on 6 ways to remove carbon dioxide has made you interested in reducing your carbon emissions to further fight against climate change – Greenly can help you!

**In addition to steep reductions of GHG emissions, the IPCC 6th Assessment Report (AR6) considers CDR to be a necessary component of successful strategies for limiting global warming to 1.5–2°C.** *The State of Carbon Dioxide Removal report* (2nd Edition, 2024) estimates that 7–9 gigatonnes (Gt) CO2 removal will be required each year by 2050 to achieve the climate targets of the Paris Agreement. Other land-based CDR approaches include **accelerated weathering** of natural carbonate and silicate rocks, methods for increasing soil carbon uptake (e.g., agricultural sequestration), and storage in above- ground biomass (e.g., **reforestation/afforestation**). **Existing programs and activities in global carbon cycle, marine ecosystem, and climate research are essential for informing CDR research, and include: NOAA’s global to coastal observing networks and data assimilation, NOAA’s Earth system and regional ocean modeling, and NOAA’s ecosystem research.** NOAA’s existing and innovative assets can inform evidence-based decisions on implementation of CDR techniques by federal and state agencies, the private sector, and nonprofit organizations.

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.

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.

His research focuses on the innovative application of environmental laws to emerging technologies, including climate engineering, deep decarbonization, nanoscale materials and microplastics, and climate liability. His research lab is developing a range of electrochemical processes to help industries become more energy efficient and to capture carbon dioxide from ocean and air point sources. **How should we support research and development in the CDR arena to more effectively meet goals related to decarbonization and clean energy efforts?**. **MR:**Several markets exist for the carbon dioxide captured through CDR processes, but the most common application is in enhanced oil recovery.

# DOE Explains...Direct Air Capture. The Department of Energy’s Regional Direct Air Capture Hubs program will develop four domestic direct air capture hubs to demonstrate a direct air capture technology or suite of technologies at a commercial scale. The Department of Energy’s Regional Direct Air Capture Hubs program will develop four domestic direct air capture hubs to demonstrate a direct air capture technology or suite of technologies at a commercial scale. **Direct air capture** technology is a form of carbon dioxide (CO2) removal that takes CO2 from ambient, or still, air. ## DOE Office of Science: Contributions to Direct Air Capture. DOE supports direct air capture research, development, and demonstration through the Offices of Fossil Energy and Carbon Management and Clean Energy Demonstrations and the Advanced Research Projects Agency–Energy. DOE also supports research on direct air capture through the Office of Science Basic Energy Sciences (BES) and Biological and Environmental Research (BER) programs.

### The Ocean as a Part of the Climate Solution: Marine Carbon Dioxide Removal (mCDR). The sheer scale of the ocean also means that any marine carbon dioxide removal solutions proven to be viable and safe have the potential to go to the scale needed. Ocean Based Carbon Dioxide Removal.

The road maps are focused on electrochemical CDR, microalgae cultivation and carbon sequestration, blue carbon restoration and carbon sequestration, macroalgae cultivation and carbon sequestration, and ocean alkalinity enhancement. There has been a great deal of debate about the potential contributions of marine carbon removal techniques to help blunt the ocean-climate crisis, but the reality is these discussions are occurring in an environment of very limited field data. ### Core Principles Guiding Ocean Visions' Work on Carbon Dioxide Removal and the Ocean.
