A Tale of Two Seaweeds
A Tale of Two Seaweeds
"CO₂"
Send personalized greetings that also positively impact our climate. Our "A Tale of Two Seaweeds" card depicts the innovative technology of seaweed sinking. While seaweed is usually beneficial, sargassum seaweed is exploding in its habitat due to warmer water and is invasive when it washes up on land in the surrounding coastal regions. Scientists have discovered how to use sargassum seaweed in a way that is beneficial to our climate by using robots to collect it and sink it to the deep ocean, where it will sequester the carbon for hundreds of years. To complete this purchase, simply select a carbon dioxide removal method and a price point to remove carbon dioxide by the kilos or the ton. Planet Earth thanks you.

Our Solutions
Biochar
Biochar starts as biomass – plant matter, old wood, agricultural waste – that is pyrolyzed, or heated to high temperatures without oxygen. The result is a solid chunk of carbon that no longer releases CO₂ back into the atmosphere. Biochar is an example of a CDR method that comes with an end product that can be used for many things including as a soil amendment, to build roads, water filtration, and so much more. Our biochar removals are supplied by CarboCulture.
Bio-oil
Bio-oil starts off as biomass and undergoes fast pyrolysis. This results in something similar to crude oil, but with less viability as a fuel. Since it has a density similar to crude oil, it can be injected into wells left empty by the oil and gas industry without risk of leaking back out into the atmosphere. It’s basically a way of putting oil back where it came from. Our bio-oil removals are supplied by Charm Industrial.
Concrete Mineralization
Concrete is the most abundant human-made material on earth, with billions of metric tons poured annually. Mineralizing captured CO₂ in concrete improves the concrete’s compressive strength, allowing concrete producers to safely lower the carbon footprint of the concrete—with no impact on quality or performance. Once mineralized, the CO₂ is prevented from releasing into the atmosphere for generations. Our Concrete Mineralization credits are supplied by CarbonCure.
Direct Air Capture
Direct Air Capture (DAC) is the process of removing CO₂ directly from the air using various methods such as adsorption, absorption, or chemical reactions. The captured CO₂ can then be stored or utilized in different ways such as injecting it underground for long-term storage, growing plants in greenhouses, or substituting fossil-sourced CO₂ in industrial processes. Our DAC removals are supplied by Climeworks.
Enhanced Rock Weathering
Weathering refers to the natural process whereby CO₂ comes into contact with water and alkaline minerals. The chemical reactions that then take place result in stable carbonate minerals that essentially trap the carbon. The enhanced part means that humans step in to make this happen on a faster time scale. One approach uses abundant, naturally reactive silicate rock, grinding it and letting it react with water.
Reforestation
Reforestation is the process of planting trees in areas where forests have been cleared. Trees absorb and store carbon dioxide from the atmosphere through photosynthesis, thus serving as carbon sinks. In addition to sequestering carbon, reforestation can also provide a range of other environmental benefits, such as preserving biodiversity, reducing soil erosion, improving water quality, and enhancing the livelihoods of local communities. However, it's important to note that reforestation efforts must be carefully planned and monitored to ensure long-term success and maximum carbon sequestration potential. Our reforestation removals are supplied by Living Carbon. You can read more about forest carbon here!
Seaweed Sinking
Seaweed can absorb carbon faster than forests and grows in the ocean without the need for freshwater or additional nutrients. Sargassum seaweed, an invasive species, is used for carbon dioxide removal while providing the co-benefit of cleaner coastlines and healthier ocean ecosystems. Our Seaweed Sinking removals are supplied by SeaGen.
Soil Sequestration
Soils can hold more carbon than the atmosphere, and healthy soils are full of carbon. Regenerative agricultural practices, such as no-till or cover crops, restore carbon-depleted soils and improve fertility. Soil carbon sequestration is a great example of how low cost, simple changes can have a big impact on the climate, as well as improve agricultural ecosystems and the sustainability of our food supply. Our soil removals are supplied by Nori.
