The Boston Properties penalty is “$112 per tonne of CO₂e overrun, indexed annually to the EU ETS futures strip”.

Now reads

The Boston Properties penalty is “$112 per tonne of CO₂e overrun, indexed to the EU ETS December‑28 settlement strip”.

Editor's note — Distinction matters: at the front‑month strip the penalty currently lands materially below several Tier‑1 cost‑of‑reduction curves. Surfaced by a reader letter from Tetragon Advisory; credited.

… the signalling crew failed to follow the lift plan, and the operator proceeded despite the obstruction.

Editor's note — Rigging and signalling are separate ASME B30.5 certifications. Conflating them is a category error, and one with safety implications. Reporter and copy desk briefed; "rigging vs. signalling" added to the trade‑terminology style sheet.
