In this editorial, we discuss the necessary steps to guarantee the sustainability of Ambiente & Água journal as it grew in recognition by the scientific community. To publish world class scientific papers of professional quality, considerable amount of resources are necessary. Therefore, we will follow the trend of successful journals that have raised several funding sources to support the processing costs to publish in cutting edge technology that requires interoperability throughout a variety of platforms.

In this 25th issue, we are publishing 15 peer-reviewed papers in a variety of environmental themes.
