DRAFT 26 JUNE 2018 Program & participant list

Meeting Room: Kulturen - Auditoriet, Tegnérsplatsen 6, 223 50 Lund

Travel:

Lund can be reached easily by public transport. It has excellent connections to Sturup airport (near Malmö) by flygbus (30 mins) and by express train to Copenhagen Airport (CPH; 30-35 mins). From the train station in Lund you can walk to the venue in about 15 minutes. More extensive travel info is available on the Lund University website. Train and local bus tickets can be bought using the Skånetrafiken app on your mobile.

Because of its attractive position as university town, Lund has many good restaurants and hotels. Please find here some hotels in the vicinity of city centre if you need accommodation, in no particular order, with a price indication per single room per night. ICOS Carbon Portal and Lund University have no connections with these hotels. Another possibility for accommodation is Malmö, a medium size city at 10 minutes by train from Lund. he More Hotel **** (€125), Concordia **** (€115), Hotel Lundia **** (€140), Forenom Aparthotel **** (€ 115), Hotel Finn *** (€78), Grand Hotel **** (€175), Best Western Plus Nordic Lund **** (€138) TRANSCOM-IG3IS meeting program Lund, 17 – 20 September 2018
