If you choose to use our organizing tools for your conference (website creation, program maker, management of participants, abstract/registration handling, ...) and not run the conference with us then it is all free.
If you run the conference with us, then our pricing includes a carbon offset for each organized conference to limit the impact of research activities on our Planet. Therefore, the pricing is mostly set by the number of people participating to the conference and the number of days it lasts. It also depends on whether one wants to record and keep the conference video accessible online. Note that the conferences with less than 50 participants lasting for less than 3 days are free (except for carbon offsetting fees, which you can do on your own and send us the certificate or offset directly on our website).
Note that there are two options for when you run the conference with our streaming tools: 1) The simplest option is that you share the conference fees between everyone by choosing a unique fee per person of 20€ (it includes everything such as technical support and we also offset the carbon emissions). 2) The organizers can pay the fees themselves. In this case, you can decide to ask for a small participation fee to all of your participants so that the overall cost is shared across many people. Your organization/institute can even make profits (to be used in an altruistic fashion to offset more emissions than produced by your virtual workshop or to fund your carbon offset policy at your own institute for instance) as for instance asking for a small amount of 20 € to each of the 100 potential participants already covers the expenses for the conference and CO2 offset (about 260 € for three days) and leaves a profit of about 1500 €.
To check the ways we use to offset carbon emissions, check this page. Our policy on this is to use methods that are effective at actually removing CO2 from our atmospheres, in quantities, which can be measured accurately.
For the 2nd option, we show some typical examples of pricing for different size conferences (for more than 1000 participants please contact our sales department as we can host events with up to 10,000 persons). These numbers can vary depending on the specific configuration you end up choosing.
