How sonochemistry contributes to green chemistry?

•Sonochemistry brings many benefits in terms of green chemistry.•The study of mechanisms is crucial to understand how improve an ultrasonic process.•In 2016, 33.3% of publications in Ultrason. Sonochem. were about green chemistry. Based on the analyses of papers from the literature, and especially those published in Ultrasonics Sonochemistry journal, the contribution of sonochemistry to green chemistry area has been discussed here. Important reminders and insights on the good practices and considerations have been made to understand and demonstrate how sonochemistry can continue to efficiently contribute to green chemistry area in the further studies.
