Removing and storing carbon dioxide from the atmosphere, called "negative emissions," could slow climate change. Climatologist Kira Rehfeld is working on how.

The NETPEC project converts carbon dioxide into solid carbon using solar energy and catalysts. Though still experimental, this technology could help offset emissions and support climate goals. Experts stress it's no substitute for ending fossil fuel use but a vital backup.
