These are from our 2024 CDR.fyi Year in Review, which pulls data from hundreds of public and private data sources to develop as comprehensive view of the market as possible. A lot of progress but a lot to do to scale the market:<p>Growth: The CDR market grew 78% in 2024 with the total purchased volume reaching almost 8 million tonnes. However, it is still highly concentrated, with 80% of purchases coming from Microsoft, Google, Stripe, and Frontier buyers .<p>Delivery: 318.6K tonnes of Durable CDR were delivered, a 120% increase from 2023 . The delivery-to-booking ratio remains low at 4.4%, but this is expected at this stage .<p>Investment: $836M of equity capital was invested into Durable CDR companies in 2024, a 30% decline from 2023 . However, the number of investments and average size of the investments both increased when we exclude outlier transactions in 2022 and 2023.<p>Warning Signs: The number of unique purchasers grew only 7% and first-time buyers declined 18%. Repeat buyer volume grew 95% and accounted for 91% of purchased volume; new buy volume remained essentially flat compared to 2023, and represented only 9% of purchased volume.<p>Challenges: The number of suppliers increased 16%, but consolidation is likely without an influx of new buyers. The sector is at risk of premature price-driven competition, potentially harming high-cost but innovative methods . More voluntary buyers and favorable policy are required for the market to continue growing.
