Durable Carbon removal title

To stop the climate crisis, we must cut CO₂ emissions in half over the next decade and then bring them close to zero. But emissions reductions won’t be enough to limit global warming to 1.5°C, some emissions from hard-to-abate sectors are expected to remain and to counterbalance that, carbon will need to be removed from the atmosphere and stored permanently. To address overshoot and bring temperatures back down the world also needs to remove large amounts of legacy CO₂ emissions. By supporting new ways of removing and storing carbon, we contribute to these methods developing and becoming cheaper for others to implement. As [recent research](https://www.sciencedirect.com/science/article/abs/pii/S254243512300449X) has shown, the coming decade is pivotal for carbon removal. Without the necessary support to bring it through its formative phase, CDR is not likely to be available at scale and in time to reach net-zero.

Direct Air capture with storage (DACs)

Direct air capture (DAC) with storage refers to taking CO₂ from the air using chemical or mechanical processes. Air is passed through filter mediums or liquid solutions that bind to CO₂ molecules. Once captured, the CO₂ can be stored permanently underground. The method is scalable and not dependent on rare materials, but costly and energy intensive.
