Dossier Legislative introduced 29-jul-2026
Bill introduced in Congress — not yet passed by either chamber, and not law.

A bill to require the Secretary of Energy to remove carbon dioxide directly from ambient air or seawater, and for other purposes.

Key claim: Senate bill S5170 would require the Secretary of Energy to remove carbon dioxide directly from ambient air or seawater.

Abstract

(S5170 · 119th Congress) Latest action (2026-07-29): Read twice and referred to the Committee on Energy and Natural Resources.

Why this matters

Direct air capture and ocean-based CO2 removal are among the more expensive and least-deployed climate mitigation pathways, so a statutory mandate for DOE to perform removal (rather than merely fund R&D) would shift the federal role from technology development to operational deployment. The practical effects — costs, siting, energy demand, and MRV standards — depend on scale and funding, which are not specified at introduction.
