There are four types of ESSL membership. Members can be organizations or persons, and they can either be full members or supporting members. The full ESSL membership has certain requirements outlined in ESSL’s Articles of Association (AoA). A supporting ESSL membership is, in principle, open to everyone.
The ESSL Membership entitles you to use ESWD data under conditions determined in a User Agreement or User Contract.
The following table outlines the main characteristics of the four membership types (fees as of 2023):
* Access to ESWD data is arranged through a User Agreement. The User Agreement for individual members can be found here. A draft agreement for commercial members can be provided upon request.
To apply for ESSL membership, please fill in and sign the form, and then return a scan or the original to ESSL (e-mail: firstname.lastname@example.org). You will be notified when your application for membership has been approved. Your membership will come into force as soon as your fee payment has been made to the ESSL bank account.
When applying for ESSL membership, please consult the Articles of Association, since all ESSL members acknowledge to abide by these Articles. Here you can discover who are presently ESSL’s supporting members.
Because of ESSL’s non-profit status, the ESSL membership dues are tax-deductible for members in many legislatures.
Fees for Institutional Full Membership
The fees for Institutional Full Members (for which specific conditions apply, see above) are calculated as follows:
Annual fee = S x N / 44 (rounded upward to the next multiple of 100 EUR)
Here, S is the size category that can be determined from the table below, and N is the nominal GDP per capita of the country in EUR according to EUROSTAT (currently called “Main GDP aggregates per capita – current prices, euro per capita, gross domestic product at market prices”), and if not available, according to the World Bank.
|No. of employees greater than or equal to||Size category|
This table contains some example values:
|N = nominal GDP per capita in EUR|
Institutional Supporting Members
For institutional supporting members, the annual fees depend on the number of employees of the applying legal entity. The fees are listed in this table:
|No. of employees greater or equal to||ANNUAL Fee (2023) in EUR|
|1 – 9||1500|
|10 – 24||3600|
|25 – 99||4800|
|100 – 249||7400|
|250 – 999||9800|
The Institutional Supporting Membership fee undergoes a yearly inflational compensation, based on the EUROSTAT Harmonized EU Consumer Price Index of the previous year (of the last available annual data, currently called “HICP”).
These fees have been decided by the ESSL General Assembly on 5 November 2018. In case of descrepancies between this page and the minutes of that meeting, the minutes of that meeting shall prevail.
If an ESSL membership is not a suitable form for you, you may consider to become an “ESSL Supporter”. ESSL Supporters wish to financially support the European Severe Storms Laboratory by a yearly donation of EUR 100.- as long as they want, without further obligations. Click here for more information.
