This group has begun to track global emissions of carbon dioxide on a daily basis and begun to publish this data in near-real time on an online dashboard. (discovermagazine.com)
While total emissions of carbon dioxide, or CO 2 , from fossil fuel use and land-use change combined have remained relatively constant around 40 billion metric tons over the past decade, emissions from China and India continue to increase as emissions of CO 2 generated by the United States and European Union continue to decline.

Now, Northwestern University researchers have worked with an international team of collaborators to create acetic acid out of carbon monoxide derived from captured carbon. (sciencedaily.com)
Their alternative method takes place via a two-step process: first, captured gaseous CO 2 is passed through an electrolyzer, where it reacts with water and electrons to form carbon monoxide (CO). Gaseous CO is then passed through a second electrolyzer, where another catalyst transforms it into various molecules containing two or more carbon atoms. (sciencedaily.com)
The researchers, who carried out their work in the Particles and Catalysis Research Laboratory led by Scientia Professor Rose Amal, show that by making zinc oxide at very high temperatures using a technique called flame spray pyrolysis (FSP), they can create nanoparticles which act as the catalyst for turning carbon dioxide into 'syngas' - a mix of hydrogen and carbon monoxide used in the manufacture of industrial products. (phys.org)
Syngas is often considered the chemical equivalent of Lego because the two building blocks-hydrogen and carbon monoxide-can be used in different ratios to make things like synthetic diesel, methanol, alcohol or plastics, which are very important industrial precursors. (phys.org)
For example, a one to one ratio between the carbon monoxide and hydrogen lends itself to syngas that can be used as fuel. (phys.org)
But a ratio of four parts carbon monoxide and one part hydrogen is suitable for the creation of plastics, Dr. Daiyan says. (phys.org)

Carbon dioxide removal (CDR), also known as carbon removal, greenhouse gas removal (GGR) or negative emissions, is a process in which carbon dioxide gas (CO2) is removed from the atmosphere by deliberate human activities and durably stored in geological, terrestrial, or ocean reservoirs, or in products. (wikipedia.org)
8 However, there is significant uncertainty around this number because there is no established or accurate method of quantifying the amount of carbon removed from the atmosphere. (wikipedia.org)

Scientists are looking at a technique known as ocean alkalinity enhancement, or OAE, as a potential way to remove carbon dioxide from the atmosphere. (whoi.edu)
OAE is a carbon dioxide removal approach that enhances the ocean's natural ability to remove carbon from the atmosphere, according to Subhas, a marine geochemist in WHOI's Marine Chemistry and Geochemistry Department. (whoi.edu)
Subhas said OAE is an important technique to explore because the oceans are taking up massive amounts of carbon dioxide, which traps heat in the atmosphere and, when dissolved in the ocean, can cause seawater to acidify, adversely affecting ocean health. (whoi.edu)
Supplementing the ocean's already massive natural reservoir of alkalinity can result in the ocean actually taking up more carbon dioxide from the atmosphere without provoking ocean acidification, he noted. (whoi.edu)
But when combined with emissions reductions, marine carbon dioxide removal approaches like OAE may help us avoid the worst effects of climate change and draw down emissions that are already in the atmosphere," Subhas said. (whoi.edu)
We're basically studying the way in which if we increase the alkalinity-this buffering capacity of seawater-by a little bit, can we actually pull carbon dioxide out of the atmosphere and store it safely," he added. (whoi.edu)
If we can demonstrate that carbon dioxide can be safely and effectively removed from the atmosphere with this ocean alkalinity enhancement process, that would represent an important step towards getting out of the climate crisis. (whoi.edu)

Thanks to their big, tangled root systems that grow underwater, mangroves are able to store that carbon dioxide for thousands of years after the tree itself dies. (minecraft.net)
