How the change works
- 01 / Public decision
Frequent trains between urban centers
- 02 / Physical change
Some trips may replace flights
- 03 / Possible outcome
Lower emissions depending on employment and grid
A service competitive in terms of frequency, price and duration can move part of the trips from the plane and the car to the train.
Research and local documents ↓What the evidence tells us
The AVE has connected Madrid and Barcelona since 2008; Renfe documents the improvement of the service up to direct times of about two and a half hours in 2023.
Conditions and limits
Promotional estimates of avoided emissions assume an alternative means: we do not treat them as observed savings. Construction, employment and new trips matter.
Other possible benefits
Direct connections and less dependence on airports.
