Open Access for IWA Publishing's S2O journals is made possible through a Subscribe to Open (S2O) model. Each year, institutions, organisations and individuals contribute to our annual Open Access goal by 'subscribing’ to individual journals or to the entire journal package. These S2O subscriptions allow us to waive author fees (APCs) in these journals.
To help us sustain this model and ensure that our S2O journals can remain Open Access, individual authors can choose to support the model by contributing the cost of what would have been the journal’s APC towards an individual S2O subscription. Support is possible at three different levels, $1,850, $1,200 and $500.
