Barcelona is served by the AVE high-speed train service between Barcelona and Madrid, and most other cities in Spain, as well as trains from the French SNCF-run TGV high-speed network, with direct trains from Paris (6h 44mins), Lyon, and Perpignan.

We encourage all participants of the conference to investigate and consider possibilities to travel to Barcelona by train, minimizing the carbon footprint caused by their travel.

Emissions offset

Typical values for emission equivalents produced by air travel are between 250g/km for short domestic flights, and 150g/km for long-haul flights. A one-way flight for example from Amsterdam to Barcelona thus results in roughly 762kg CO2 emissions for a return flight (2,582 km):, non-CO2 emission impacts not considered. Taking a long-distance train will reduce emissions to roughly 10% or less. (return 3,066km): 6kg CO2 emissions Detailed calculation for your trip can be investigated at: or

Should you decide to travel by air, you may wish to consider offsetting travel-related emissions through donations to solar, biomass, or energy-efficiency projects. Alternatively, you may compensate the CO2 emissions separately through services or other similar organizations.
For the EMS2023 in Bratislava, 20% of the onsite attendees (or their employers) did pay compensation denotations to offset the emissions induced through their travelling to meeting.
