American Airlines aims to remove carbon from the atmosphere by working with a startup that stores bricks of plant material underground. The airline announced a deal with Graphyte on Tuesday to purchase credits equivalent to 10,000 tons of permanent carbon removal with delivery scheduled for early 2025. The plant material is dried to prevent decomposition and then converted into carbon dense bricks that are sealed with a polymer barrier. Plant byproducts from the agriculture and timber industries are typically burned or left to decompose, which returns carbon dioxide into the atmosphere. This biomass material is equivalent to 3 billion tons of potential carbon dioxide removal annually, according to Graphyte.
