Methane Monitoring Science Act would direct NASA to improve detection of agricultural and industrial methane Two lawmakers introduced the Methane Monitoring Science Act to direct NASA to improve the nation’s ability to detect methane emissions from agriculture—including livestock—and industrial sources. The bill seeks expanded satellite and measurement capabilities to locate and quantify leaks for mitigation and enforcement.

Air France–KLM hit with €7.5m penalty after missing 2025 jet‑fuel GHG targets tied to €1bn green bond Air France–KLM expects a €7.5 million (USD8.8 million) cost after failing to meet 2025 jet‑fuel greenhouse‑gas targets tied to a €1 billion (USD1.1 billion) green bond. The missed target will be recorded as a penalty against the group's results and underscores tangible costs of corporate decarbonisation commitments.

Leeham: Is Boom’s Supersonic Bet Doomed as Military ‘Green’ Policies Falter A Leeham News column questions whether Boom Supersonic’s commercial bet remains viable as faltering military ‘green’ policies remove a potential demand pillar. The piece also criticizes urban air mobility hype, calling eVTOLs “perfectly mediocre” and overpriced in its assessment.

Sustainable water recycling for long‑duration space habitats Water for drinking, hygiene and plant growth is a primary constraint on long‑duration human spaceflight: resupplying the ISS costs on the order of tens of thousands of dollars per delivered mass. Durable, efficient closed‑loop water sourcing and reuse are essential to enable months‑to‑years surface and orbital habitation.
