Judging fusion on its whole lifecycle, not just clean operation.

Scope
Cradle to grave

An honest environmental case looks at the whole lifecycle — construction materials and embodied carbon, operation (zero-carbon, low waste), and decommissioning (short-lived activated material). Kronos frames its environmental screening this way, flagging the items still to be computed.

Zero operational carbon is not the whole story, and Kronos says so.

Common questions

What does a lifecycle assessment cover?

All the environmental inputs and outputs across a plant's life — construction materials, water and land use, operation and decommissioning — not just what comes out of the stack during operation.

Has Kronos finished one?

Kronos screens lifecycle impacts by product and flags what remains to be computed rather than publishing a finished, polished number it cannot yet defend.
