Carbon intensity measures the CO₂ emitted per kilowatt-hour of electricity. It falls when wind, solar, nuclear and hydro dominate, and rises when gas fills the gaps - the number below refreshes about once a minute.

The band (very low to very high) is the Carbon Intensity API's national rating; measured is the settled figure, forecast the estimate before it settles.
