ICE Futures Europe, the biggest exchange for carbon trading, said it might extend a 16-month suspension of its prompt market as it waits for a software upgrade at a new European Union registry.
The upgrade will allow traders to set up so-called trusted accounts in the registry, which tracks ownership of emission allowances. Without those accounts, which will allow for streamlined trading, transactions may take as long as seven days to settle, said David Peniket, the exchange’s president.
