Indianapolis International Airport rebuilt its 10,000‑foot Runway 5R‑23L using concrete that captures and permanently stores carbon dioxide, completing a $190 million project approved by the Federal Aviation Administration.
The new pavement, laid with CarbonCure technology that injects recycled CO₂ into fresh concrete, replaced more than 450,000 square yards of surface and is expected to have a 40‑year service life, while the captured carbon is said to equal the CO₂ associated with planting about 1.2 million trees.
