The ocean absorbs nearly a quarter of global CO₂ emissions each year. In theory, it could take in even more, but not without consequences. Ocean acidification and warming threaten the ecosystems that depend on stable pH levels and temperatures. To protect these systems, we need additional carbon removal pathways that complement natural ocean processes rather than overwhelm them. Blue carbon ecosystems — mangroves, seagrass meadows, and tidal marshes — cover only about 2% of E

Direct Air Capture (DAC) is one of the most technical and futuristic carbon removal (CDR) strategies. At a high level, DAC works like a giant air filter pulling in ambient air, capturing CO₂, and converting it into concentrated forms that can be safely stored underground or used in products such as concrete and building materials. Can DAC Scale? Understanding the Technology Behind the Promise The biggest unanswered question around DAC is not whether it   works   (it does), bu

Agricultural and organic waste can be transformed into long-lived products or buried for durable storage. As a matter of fact, any plant can be used in biomass carbon dioxide removal (biomass CDR). With roughly half of U.S. garbage being food waste, this represents a massive, largely untapped opportunity. Biomass CDR approaches include burying trees in low-oxygen environments, transforming plant material into bio-oil for underground injection, or producing biochar through con

Forests are often called “the lungs of the Earth,” and for good reason. As they breathe in carbon dioxide and exhale oxygen, trees lock carbon into their trunks, branches, and soils for decades. But forests do far more than clean our air, they are a scalable and cost-effective natural climate solution. The cool thing about trees is as long as they’re alive, they will never stop capturing carbon. It is widely accepted that young trees capture more carbon than their fully grown

Soils play a central role in the global carbon cycle – storing more carbon than all vegetation and the atmosphere combined. This massive natural reservoir not only supports plant growth, but has the potential to sequester carbon over meaningful timescales. Despite its potential, soil carbon storage is dynamic – meaning its permanence, or how long carbon remains stored, can be uncertain. Land management practices like tilling or environmental disturbances such as drought or ri

Why does carbon dioxide removal (CDR) matter?  Whether you’re new to the CDR space or you’ve been here for a long time, it’s important to have a high level understanding of each methodology that exists to fight the ever increasing effects of climate change. I recently completed the   AirMiners   Bootup course. If you’re interested in expanding your knowledge of CDR, the next cohort begins on November 11 ( https://bootup.airminers.com/ ).   There are   six main categories of C
