KEY TAKEAWAYS
Spain may ban short-haul flights if there are train options that could handle the same trip of less than 2.5 hours.
This measure is estimated to lower in total over 30,000 tons of CO2 annually.
A study by Greenspace analysing 14 routes to and from Spain showed that train travel costs are nearly four times more than flying.
