The Slovenian Environment Agency (ARSO) has kindly proposed to host the 2nd ACCORD ASW in Ljubljana, from April 4 to April 8 2022 at Austria Trend Hotel Ljubljana.

The meeting is organised as an hybrid meeting, with participants in Ljubljana hotel and remote participants.
With this hybrid format, the ASW will be organised over 5 full days (4-8 April). No LTM nor MG meetings will be organised this very week.

Participants, chairs, speakers, poster presenters: please consult the Guidelines for a smooth ASW and pay attention to the documents to provide in advance (pdf files of posters/presentations, slide for posters session).

Local information

Block reservations have been made at two hotels:Austria Trend Hotel Ljubljana (registration form, deadline is 16 March) and City Hotel Ljubljana (please send an e-mail to reservations@cityhotel.si with code reference ACCORD2022). All details in the comprehensive information document prepared by our hosts. Other hotels are also suggested in the document.
The hosts highly recommend to take lunch (self-service buffet, contribution 10€) at the restaurant of the hotel, as there are not many restaurants surrounding the venue, some have also not yet reopened after Covid-19. They will ask in-situ participants for information about lunches and dinner on Wednesday some days before the event. Those who will stay at the Austria Trend Hotel can apply for the lunch already now when filling registration form.
