"You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete."

Buckminster Fuller, philosopher, futurist and global thinker (1895 - 1983)

Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs."

The Report of the U.N. Brundtland Commission, Our Common Future, 1987

"If there are to be problems, may they come during my life-time so that I can resolve them and give my children the chance of a good life."

Kenyan proverb


Visa information


SDEWES2020 Conference will be held in Cologne, Germany and if you are not an EU national or you do not have a valid Schengen document, you might need a Schengen short-stay visa. Please check here countries whose citizens require/do not require visas to enter Germany. Germany is a part of the Schengen area, for more information on the visa policy of the Schengen Area see here.

Holders of:

  • a multi-entry Schengen visa (text on the visa reads “valid for Schengen states”),
  • a residence permit of a member state or
  • a national visa of a member state

can also travel to Germany for up to 90 days in any period of 180 days. The Schengen visa should, however, have been issued by a mission of the country which is the main destination. The country of entry and departure is not the determining factor. On the planned date of departure from Germany, your passport has to be valid at least for another three months and it has to be issued within the last 10 years.

If you are not sure whether you need a visa for coming to Germany, please contact your nearest German consulate/embassy or visit this page.

If you are certain that you need a visa, you will need to apply for a short-term stay in Germany, Schengen visa type C. You will find all the necessary information on the official Federal Foreign Office Visa regulations website.

Instructions for visa procedure for SDEWES participants


Participants who require a visa for Germany need to select the “Visa letter” option in the conference registration system. The Conference will issue a certified Invitation letter, necessary to apply for a visa, only to registered authors with accepted papers and settled fees.

Participants need to apply for an invitation letter as a part of their registration in the FEE/REGISTRATION menu.

Please respect the deadlines for settling the fee in case you need a visa and don't forget to select this option in the system. Reduced and special reduced fees will be charged with an additional visa fee.

Where to apply?
Information on the diplomatic missions and consular posts of Germany where you can submit your visa application is available here. Following its entry into the Schengen area, Germany is also represented in the visa procedure by some other Schengen States. Thus, at locations where Germany does not have a diplomatic mission or consular post authorised for conducting visa procedures, you may apply at the representations of Schengen States.

As a rule, missions require between two and ten working days to decide on an application for a short stay visa. During the peak travel season, there may be a waiting period for making an application to a German mission. Persons requiring a visa to enter Germany should, therefore, submit their applications in good time. Visa application cannot be started earlier than three months before the start of the conference.
