Funding comes from several parties and friends of the Syrian people through international institutions, such as funding from USAID, from the United States, and from the U.K. government. There's also funding from Japan, the Netherlands, Denmark, and Germany. These are the states providing support and funding through international institutions.
As for decision-making and governance in the White Helmets associations, there are elections on a yearly basis. For the Syria Civil Defence stations, there is a general bureau or authority that takes decisions. Another executive bureau is elected within Syria, and it makes all the decisions regarding Syria Civil Defence, or the White Helmets.
