March 3, 2026 — U.S. lawmakers in Congress have introduced legislation to improve research into removing carbon dioxide from the ocean, potentially through aquaculture practices like seaweed farming.
“Carbon dioxide removal is an essential tool in the fight against the climate crisis, in addition to being a driver of American innovation,” U.S. Senator Brian Schatz (D-Hawaii) said in a release. “Our bill will encourage research into mCDR [marine carbon dioxide removal] to ensure it’s safe and effective, benefits coastal communities, and protects ecosystems.”
