Partial Data

When only one type of emissions data is available, the component shows what it can.

Current emissions only

Only current flight emissions available - no comparison possible

Current Emissions
This journey	95 kg CO₂

Emissions are calculated for 1 passenger in this class

Average emissions only

Only route average available - no specific flight data

Average Emissions
Typical for this route	115 kg CO₂

Emissions are calculated for 1 passenger in this class

No Data Available

When no emissions data is available, the component shows an appropriate message.

No emissions data

Neither current nor average emissions data available

Emissions are not available for this flight

Zero emissions data

Zero or invalid emissions values

Emissions are not available for this flight
